Best Motor for Forced Induction

Death-the-Kid

anta honma ni shinude
I've already broken it down. Stock Vtec head. Stock LS bottom
End. As in factory spec on head and bottom end. .

that doesn't make it a stock engine lol... is a mini-me swap stock? no it's not. not to mention there are 3 heads with 3 different results.


I said one of the many reasons, not the main reason. I agree that Vtec heads greatly outflow them. Yet ANOTHER reason why it's a superior base to build on. Speaking generally.
superior is relative. the ls has more stroke and more displacement which is a great base to start off on add a vtec head and you get your power sooner with less revs required

Look up an LS/V with any Unmodifed Vtec head and unmodified bottom end.Then look at it's complete
Counterpart. That's the proof and the argument.
again which lsvtec ? one with gsr, b16, or type r head?

-b16 will yield the worst results because of the s***ty cams it comes with and that it doesn't do much for the compression

-gsr head has smaller combustion chambers and better cams with marginally less head flow over the b16. so it will yield more power and higher compression

-the type r has the best cams and flow but doesn't do much for compression

what counterpart is there? there is no counterpart it's a Frankenstein engine.





You're just pulling my replies out of context and saying im wrong. You're right about that one, if you're changing rod lengths, crankshaft and pistons then it won't matter
Much what you start with.
1. no i'm not, you're just putting your foot further into your mouth
I
There's no doubt in my mind that a GSR is a superior motor, stock or potential for being built.
2. then you just contradicted yourself because according to you the gsr will "always" finish on top no matter what.


I'm honestly not even sure what you are babbling about. The stock GSR cams were not meant to be used in conjunction with the LS stroke and compression.
what are you talking about? the gsr cams are not super aggressive so you still have a nice power band with them. do you understand how cams work or engines for that matter. gsr cams are a nice daily cam for that compression ratio and stroke will only help your powerband?

you do realize even b16's pick up 10whp with gsr cams and they are under 1.6 liters of displacement? so why wouldn't the more effective engine be able to utilize the same cams with a nice flowing head? your logic is illogical


Again.. Never said they were all the same. Simply that they all outperform an LS head and
that none of them were meant to be mated with an LS block
.


I agree. Sounds like a rarity around your parts.
I'm saying none of the parts we add to our engines were meant to be there from the factory whether it be skunk 2 cams or an itr manifold on a b16. so to say that the head was never meant to be added as an upgrade when it's been proven to to mate to the block is a retarded statement. that's why it's called a "Modification". our engines were never meant to run gt3076r turbo but people do it so what's your point?


More displacement does you no good if your air can't
Get in and out efficiently. Which brings up my point again- The cams arnt set up for an LS bottom end.

1. no s*** it's no secret more displacement isn't as effective without a better flowing head...that's why they do ls vtec hahahahhaha. I didn't know you had to set cams up for your bottom end... please explain to us how the ls bottom end can't handle gsr cams. i've gotta hear this one.


2. it's not rocket science that a vtec head out performs a non-vtec head. that's the point of lsvtec. put the bigger displacement longer stroke with the free flowing head.

3. you have very little knowledge of what you're talking about. how old are you 19? what engine are you running?

As you clearly did not read what I posted:
Look at it, too, from a manufacturing standpoint- Honda is already making the higher displacement B18A and B blocks (blocks are identical, only difference was in the head), so why go to the extra time and expense of developing and manufacturing a separate block, especially if it will decrease output?

The answer is easy: R/S.


What is R/S?


R/S is the abbreviation for rod to stroke ratio. It is the ratio of the length of the connecting rod to the length of the piston stroke, or the distance the piston travels from the top to the bottom of its stroke. As the ratio gets lower, the amount of stress on engine internals increases exponentially, killing long-term reliability. The higher the number is, the slower the piston is traveling, killing power output.

The ideal R/S is 1.75:1 (Three cheers for the B16A, at a near-perfect 1.74:1!).


Why a low R/S is bad for reliability


A low R/S means the rod will be closer to a horizontal angle on its upstroke. This means that more of its force will be pushing the piston horizontally, rather than vertically. What does this mean for your engine? Two things.

1. There will be more stress on the sides and in the center of the rod, rather than on its ends, leaving the rod more vulnerable to breaking. Picture a straw. This is no special straw, just an ordinary drinking straw. Is it going to be easier to bend this straw by applying pressure onto its ends, or at its center? Now think of your poor connecting rods.

2. There will be more stress on your cylinder walls. Once again, the rod is pushing the piston at a more horizontal angle- right into your cylinder walls, rather than up and through them. The risk here is double: A. Putting that piston right through the cylinder wall. B. The cylinder wall will actually flex under the pressure, causing the shape to turn from a circle to an oval or oblong shape. This causes the loss of the seal created by the piston rings. What happens? A small amount of oil could slip past into the combustion chamber. Bad things happen from here: The oil gets combusted, leaving nasty carbon deposits in your combustion chamber and exhaust ports- not a good thing for flow or valve sealing.

It's also important to note that as the RPMs increase, so does the amount of stress on your engine's internals.


What is power, exactly, and how do Hondas make it?

Warning: Once you see this, you will never look at horsepower and torque readings the same again, especially after you think about it.

P= (TR)/5252

P= power, in horsepower
T= torque, measured in lb/ft
R= Engine speed, in RPMs

Therefore:

Horsepower= (torque x RPMs) / 5252

Try it- pull out a dyno and see what you get.

So from this, we can conclude that if we increase torque or engine speed, we will get more power, right?

Remember that, it's important...

Now how do Hondas make power? Our tiny little 1.6-1.8L engines aren't exactly oozing spare displacement and creating gobs of torque, are they? Hondas make power through revving, and revving high. So why does everyone place so much emphasis on creating torque? It's because all these bolt-ons you see advertised won't raise your redline, but they will increase torque. There's nothing wrong with squeezing every last ounce of torque out of your engine- you should. But trying to get torque from more displacement in a Honda is like trying to fill a swimming pool using a squirt gun. You'll never get enough for it to be useful.

---
The LS/VTEC suffers from a bad R/S, due to the fact that it utilizes an LS block with a R/S of 1.54:1.
A bad R/S is bad for the engine, especially at high RPMs
Hondas make power through revving, and high power through revving higher, high compression, and aggressive camshafts

Because of its R/S ratio, it is not recommended that you rev an LS/VTEC past 6750 RPM on stock internals- the redline of a stock B18A-B. With a fairly built bottom end, it is still not recommended that you rev an LS/VTEC past 7800 RPM.

As we just discussed, in order to get any considerable power out of an engine, aggressive camshafts are a must. In order to get any benefit from aggressive camshafts, the ability to rev the engine high is a necessity. What good is VTEC if you can only use it for the top 1000 RPM of your powerband?

And because I'm on my phone I will simply link you;
http://www.phatwhippincrx.20m.com/custom4.html

I'll get back for more quoting and dyno sheets when I'm on a computer.
LOL do you know how old that info is? dude i found that years ago and it's outdated. according to that info b16's are better than b18c5's because of their rod/stroke ratio. LMAO.... that's like the old hp/liter argument actually meaning anything. he's advocating using a b16... seriously ? I know the guy he's quoting "5thgencivic. he's on www.superhonda.com. I moderate the forum he's talking about. lol b16 being fast all motor compared to what? i've been there for 7.5 years. that article was written at a time before they even had professional lsvtec install kits. back when you were using back yard parts to mate the head to the block.


jeff evans website defuses 90% of the info on that page with half of the builds he does. why don't you post some real results as opposed to a Google query of an outdated opinion page. the issues people see with lsvtecs were the rod bolts letting go at high revs like 8000+. if you upgrade them then you're fine. you want a reliable ls vtec, then do rod bolts and heads studs with possibly some bearings. why don't you phone into psi pro, or ddtech. ddtech sn here is "ALL MOTOR" he builds custom cams and engines for his business. he started with lsvtec and now rolls 2.0 vtec allmotor that smokes some crazy stuff at the track. why don't you tell him how much merit that page carries. He is also from www.superhonda.com. his SN there is 9300rpms.

http://realstreetperformance.com/store/brian-crower-1-92l-stroker-kit-honda-civic-si-b16a-84-5mm-stroke-2934.html

oh look a b16 1.9 liter stroker kit. where is the rod stroke ratio now?
As you clearly did not read what I posted:
i did and it's more proof you really don' t know what you're talking about considering i know the people in the article :roll::D

why don't you read the article more carefully, you don't even know what you're reading. do you understand that the point of building your motor isn't just hp but power under the curve. hondas are incredibly slow for the hp they produce. why do you think hondas use such obnoxiously close trannies? it's called tq multiplication because they make s*** for tq across the board. that's why i have an ls trans with b16 3rd, 4th, and 5th and a type r final drive. they have to make up for their lack of tq someway or another.

LOL. Where are you getting half of these things you're blabbering about? You're just making things up and replying to things I haven't even said. Haha. Seems to be your knack.

I'm not even sure what you're looking for anymore. I give you my reasons for my opinion.. You say crap out of no where, throw in a few uneducated insults, an tell me to prove my point more. I give you a link, and you simply say its wrong because you know the guy.

umm.. it's all in the article you posted... or did you not read it all? :lol:



i know this guy and he has no idea what he's talking about. Where they make reference to "SHO" they are referring to www.superhonda.com.... did you not read your own article? lol this article was written at a time when they didn't have golden eagle kits. back when they were hit or miss.


blabbering about? you mean the facts you keep ignoring? or the fact you have proven you have no idea what you're even talking about.

"ls bottom end wasn't meant to handle gsr cams"

really dude? no wonder you haven't seen a decent lsvtec? if half of your friends have as much "knowledge" as you do, i doubt they could even change their own oil without throwing a rod...

This arguement has done two things.
1. taught me a ton about ls/vtec builds (which I'm currently doing)
2. Made me want to get started on my build!
Death has very valid points and actually owns an ls/v, whereas Prozon doesn't. My point would be that the technology of ls/v's has evolved and become a great build if done correctly. I have a b20b and plan on putting a b17 head I picked up on it. A b17 not because of power, but because of the "rarity" and I have a full b17 laying around with a cracked block.

i've had 2 b18c1's before i had this motor so i appreciate both sides. never had a crvtec before. honestly though this motor is getting torn down once i finish working on my civic. gonna drop some forged internals in the lsvtec and all new gaskets and shoot for 400whp on pump gas. that's why it's not bad to start off with an b18b and add a vtec head down the road or whatever else you want to upgrade as you want to make more power. you can literally decide which direction and where you want to invest money as you go.

crvtec are nice for all-motor builds and low boost builds(due to the sleeves). throw 5 lbs of boost at it off of a small trim turbo have a quick little bugger.

there is a girl here with an automatic crvtec...




it's automatic because she has a birth deformity which prevents her from shifting. it's on an ls auto trans. i keep trying to tell her that she should upgrade to the automatic gsr trans. it still walked a mugen civic si

Let me go back and properly quote and address everything I have missed or just poorly responded to. I'm actually on a computer now and can actually see what I type. It's difficult to type out replies and quotes when I have to scroll three times to get to the end of a sentence.

you can't make blanket statements like that. do you know how hard it is to get to 180whp with a gsr or any non k-series engine from honda? and any gsr that is at my whp level with similar mods would have problems touching my tq curve. and the initial cost for either motor is considerably more expensive than an ls block.now should you throw away your gsr for an lsvtec? no. it's not cost effective. but if you're goal is to build a motor from the ground up and you already have an ls block there is no need to spend 2500K+ for a 142whp gsr engine
If we're using the term blanket statement, we might also throw in that this "blanket statement" is an opinion.

o·pin·ion/əˈpinyən/
Noun:

1. A view or judgment formed about something, not necessarily based on fact or knowledge.


I don't actually have to have cold hard facts as to why I believe something, hell- that's what makes an opinion what it is. However, an opinion is not simply wrong or right just because you say it is. I justified my comment with my reasoning and I will continue to do so. If you think that an LS/V is superior in any way, why would you not want to give up your GSR bottom end for an LS one? Is it because the lower compression makes for a less powerful engine?

that doesn't make it a stock engine lol... is a mini-me swap stock? no it's not. not to mention there are 3 heads with 3 different results.
i said no such thing as a stock lsvtec engine. the head in question was stock..... an lsvtec is not stock since lsvtec never came factory. the head is set to factory specs. the fact that there are 3 different variants of lsvtec and that it never came from the factory as a real motor then there is no such thing as a "stock ls vtec"
I even broke it down for you and you continue to ignore what I said, you shouldn't take things so literally. I told you what I meant by a stock "LS/V" and you continue blabbering on about it.. I think that you're taking this whole "half-assed" thing really personally. :roll:

superior is relative. the ls has more stroke and more displacement which is a great base to start off on add a vtec head and you get your power sooner with less revs required
More displacement by .1, in my opinion it's not enough to make a difference.


1. no s*** it's no secret more displacement isn't as effective without a better flowing head...that's why they do ls vtec hahahahhaha. I didn't know you had to set cams up for your bottom end... please explain to us how the ls bottom end can't handle gsr cams. i've gotta hear this one.
I never said it couldn't "handle" it, did I?? I didn't mean to if I did, simply that it's not SET UP for it.

2. it's not rocket science that a vtec head out performs a non-vtec head. that's the point of lsvtec. put the bigger displacement longer stroke with the free flowing head.
And losing power in the process because of the lower compression. The only reason I would run a lower compression is to boost the crap out of it, and even then it's pretty useless because now days with a good tuner you can boost higher compression and avoid melting a piston. There's not enough displacement in a Honda motor to make power simply from that- hence revving to nine grand. Do you see any V8's that rev to 10k? VERY SELDOM. Why? Because they have five times the displacement of a Honda and don't need it. I mean serious displacement, not ".1"...


3. you have very little knowledge of what you're talking about. how old are you 19? what engine are you running?
No sonny, i'm not nineteen. I don't live with my parents, and I don't simply have I/H/E. Not that age should be any factor here. (I'm not even sure why it would be.) My previous motor I rebuilt a B18b1 that made 261hp on 10psi. I've since pulled that motor to drop in a friend's CRX. The shell is most likely going to be parted until I find a better candidate for the new motor. My current motor (on the engine stand) is a B18c1. Benson Sleeves, Manley Rods and CP Pistons running 10:1 compression. ARP head studs. ACL Bearings. The head has had a port job done as well as crower valvetrain. Freshly rebuilt Garret T3/T4 57 trim ready to bolt on. Machining done at D&G Performance.. Yadda yadda.. forgetting quite a bit..

it's outdated. according to that info b16's are better than b18c5's because of their rod/stroke ratio. LMAO.... that's like the old hp/liter argument actually meaning anything.
It never said that, but then again you're not good at reading. It simply states that the B16 has a better R/S and that he would prefer a B16 over a LS/V. I don't think I read anywhere in there saying "The b16 is a better motor than the B18c5" simply that it has the best R/S.

jeff evans website defuses 90% of the info on that page with half of the builds he does.
Defuses that info, how? Because there are LS/V's making serious power with some serious cash put into them? The point is again moot- we're not talking fully built motors with thousands sunk into them. I'm speaking of stock versus stock here. There's no doubt that you could make any motor make some serious power. But the cash put into them to make them reliable and powerful isn't worth it in my opinion. Hell, you have to sink what- a grand into a "kit" to make an LS/V reliable in the first place? (I could be off on that price, I haven't looked into LS/V kits.)

why don't you read the article more carefully, you don't even know what you're reading. do you understand that the point of building your motor isn't just hp but power under the curve. hondas are incredibly slow for the hp they produce. why do you think hondas use such obnoxiously close trannies? it's called tq multiplication because they make s*** for tq across the board. that's why i have an ls trans with b16 3rd, 4th, and 5th and a type r final drive. they have to make up for their lack of tq someway or another.
An an LS bottom end isn't going to make up for that. Incredibly slow for the HP they produce? In my experience they're a lot faster then a few other things. Power to weight ratio is a big player in that one. Not only is weight a huge factor, but so is gearing as you stated. But then again, why are we getting into this? We're speaking of LS/V's and any torque gains from an LS bottom end is purely insignificant in the matter. (In my opinion.)



the main reason you don't see 600np non-vtec engines is because their head flow is s***. even a worked non-vtec head will not outflow a stock vtec head. it's all about the cfm. not their rocker arms. you throw rocker arms with revs not hp.
I said one of the many reasons. I never said it was the the main reason. And believe me, a ported non vtec head can flow enough to make the power. It will probably never outflow it's vtec counterpart, but it can be done. We already talked about this. Revving is part of a Honda, they have no displacement and make their power through revs. Put a 5k RPM rev limit on a Honda motor and see how much power you get out of it. The idea that you don't have to rev a Honda high to make that kind of power is a little absurd in my mind. I have yet to see a Honda make real power below 5k.

there is no debate. you talking out of your butt and haven't provided any proof to back anything up that you have said. you simply refuse to listen. i give you facts and examples from real life experiences and other sources. other members have even chimed in yet you live in your delusional bubble and proceed to spread mis-information
Just because you disagree does not mean I am spreading misinformation or talking out of my butt. Sorry to burst your bubble..


they make the same hp if not more than a gsr with more tq with stock parts. how is that half-assed? a gsr in stock form is also half-assed then.
And where are you getting THAT information? You keep showing me built motors making more power. Lets throw up a stock ls bottom end with a stock C1 head slapped on. They don't make as much as horsepower.

142-145whp in pristine condition and 110wtq? yeah that sounds impressive and they only cost $2500
I could get a complete swap for $2500, transmission axles, ecu and everything for less then that. Where the f*** are you buying $2500 GSR's from? Hell, surf Craigslist and there's numerous GSR's on there for less. I bought my complete GSR for $500. (Minus a wiring harness, distributor and injectors.)


stock head from one motor and stock bottom from another motor doesn't make the motor stock.
No, but when I say "stock ls/v" I am referring to a stock bottom end, with a stock vtec head. Okay? DO YOU UNDERSTAND?? Do I need to repeat it for the tenth time? Sorry if my terminology is off!! bear with me you f***ing prick. -_-


No my argument is you can't make blanket statements because of your own ignorance and lack of experience. saying that a said motor is half-assed when it's been proven time and time again otherwise.
I've already addressed my position on the whole blanket statement arguement. Again, it is my personal opinion.. re-read that a few times, because as much as you're saying "You're dumb, blah blah blah." You seem to misread or ignore quite a few things I have said.

and my remark was in reference to you saying that an lsvtec will never be on par with gsr in terms of using stock parts for initial power or aftermarket parts for potential higher hp. which is a ludicrous statement because they can use the same parts.
No, they can't. You cannot put LS parts in a GSR and say they are stock GSR parts. It doesn't work like that. The statement isn't ludicrous if you read it correctly.


their bottom ends weren't setup to make HP? lol you've gotta be kidding me. they have the same hp limitations from the factory as a gsr. LMAO are you kidding me? a stock gsr and a stock ls both hit the limit of reliability around 300whp. who told you that it wasn't setup for hp. the only weak point they have is the rod bolts which isn't an issues until you start wanting to consistantly hit 8K+rpms.
I never said anything about horsepower limits, quit pulling this crap out of thin air. You need to read what I type, and then read it again, and then once more to be sure. I swear it's like you're twelve. You see one word and you just draw conclusions as to what that word could have been leading to...
As I stated somewhere, at some point during this whole jumble of nonsense- the lower compression of an LS block won't make the same power as say a full GSR. The .1 displacement is not enough to make up for the lower compression.. as you could tell if you pull up a LS/V that has not been BUILT.

any build will not make the desired power if not built properly.
An LS V consisting of a stock LS bottom end and a stock vtec head will not make as much power as a full vtec motor. That's the point. No need to bring up dyno sheets of motors with cams, pistons, port jobs, ect ECT, because that's not the point i'm addressing.

ummm none of our engines were meant to have upgraded parts from the factory hence why that statement is just retarded. then again this is coming from the guy that thinks all vtec heads are the same.
Never said that. Just that they were all superior then a non v, and that the full version is better then the unmodified LS/V variants. Should have expected that from the guy who can't read..

it's evident you've never actually modified an engine before or been around quality builds. and you just contradicted yourself yet again.
The above mentioned motors don't count I assume.. :roll: I do a helluva lot more then tinker with Honda's.

and how does more stroke and more displacement which means more volumetric capacity with the same head flow equate to less power ? engine is an air pump. more air equals more what? i'll let you think about it.
WHOA! More air in and more air out means more power? You sir are a genius! The first modfication most people do are generally intakes and exhausts, for JUST that reason. I think any kid with a set of car keys can tell you that much. This is the basis of everything we do to make power. That's where compression comes into play, you can have the same airflow yet produce better power with compression because the mixture will burn better. Now this isn't the only thing involved obviously, but I don't think I need to explain how combustion engines work to you.. do I....? "I'll let you think about it."

I've spent entirely too long typing this.. My friend pointed out to me that this has gone on quite a bit longer than it should have. I think at some point we're just going to have to agree to disagree, because I doubt i'm convincing you and I know you're not convincing me. But in the case that you won't agree to disagree.. well i'll see you tomorrow for what i'm sure to be an educational and mature argument. :roll:

An an LS bottom end isn't going to make up for that. Incredibly slow for the HP they produce? In my experience they're a lot faster then a few other things. Power to weight ratio is a big player in that one. Not only is weight a huge factor, but so is gearing as you stated. But then again, why are we getting into this? We're speaking of LS/V's and any torque gains from an LS bottom end is purely insignificant in the matter. (In my opinion.)




I said one of the many reasons. I never said it was the the main reason. And believe me, a ported non vtec head can flow enough to make the power. It will probably never outflow it's vtec counterpart, but it can be done. We already talked about this. Revving is part of a Honda, they have no displacement and make their power through revs. Put a 5k RPM rev limit on a Honda motor and see how much power you get out of it. The idea that you don't have to rev a Honda high to make that kind of power is a little absurd in my mind. I have yet to see a Honda make real power below 5k.


Just because you disagree does not mean I am spreading misinformation or talking out of my butt. Sorry to burst your bubble..



And where are you getting THAT information? You keep showing me built motors making more power. Lets throw up a stock ls bottom end with a stock C1 head slapped on. They don't make as much as horsepower.


I could get a complete swap for $2500, transmission axles, ecu and everything for less then that. Where the f*** are you buying $2500 GSR's from? Hell, surf Craigslist and there's numerous GSR's on there for less. I bought my complete GSR for $500. (Minus a wiring harness, distributor and injectors.)



No, but when I say "stock ls/v" I am referring to a stock bottom end, with a stock vtec head. Okay? DO YOU UNDERSTAND?? Do I need to repeat it for the tenth time? Sorry if my terminology is off!! bear with me you f***ing prick. -_-



I've already addressed my position on the whole blanket statement arguement. Again, it is my personal opinion.. re-read that a few times, because as much as you're saying "You're dumb, blah blah blah." You seem to misread or ignore quite a few things I have said.


No, they can't. You cannot put LS parts in a GSR and say they are stock GSR parts. It doesn't work like that. The statement isn't ludicrous if you read it correctly.


I never said anything about horsepower limits, quit pulling this crap out of thin air. You need to read what I type, and then read it again, and then once more to be sure. I swear it's like you're twelve. You see one word and you just draw conclusions as to what that word could have been leading to...
As I stated somewhere, at some point during this whole jumble of nonsense- the lower compression of an LS block won't make the same power as say a full GSR. The .1 displacement is not enough to make up for the lower compression.. as you could tell if you pull up a LS/V that has not been BUILT.


An LS V consisting of a stock LS bottom end and a stock vtec head will not make as much power as a full vtec motor. That's the point. No need to bring up dyno sheets of motors with cams, pistons, port jobs, ect ECT, because that's not the point i'm addressing.


Never said that. Just that they were all superior then a non v, and that the full version is better then the unmodified LS/V variants. Should have expected that from the guy who can't read..


The above mentioned motors don't count I assume.. :roll: I do a helluva lot more then tinker with Honda's.


WHOA! More air in and more air out means more power? You sir are a genius! The first modfication most people do are generally intakes and exhausts, for JUST that reason. I think any kid with a set of car keys can tell you that much. This is the basis of everything we do to make power. That's where compression comes into play, you can have the same airflow yet produce better power with compression because the mixture will burn better. Now this isn't the only thing involved obviously, but I don't think I need to explain how combustion engines work to you.. do I....? "I'll let you think about it."

I've spent entirely too long typing this.. My friend pointed out to me that this has gone on quite a bit longer than it should have. I think at some point we're just going to have to agree to disagree, because I doubt i'm convincing you and I know you're not convincing me. But in the case that you won't agree to disagree.. well i'll see you tomorrow for what i'm sure to be an educational and mature argument. :roll:
1. it's not just .1 displacement it's the stroke as well. makes more power sooner. and i just showed you that you can make up for the lower compression ratio. hence the dyno that i have provided.
2. stop offering your opinions as facts. where did you justify your opinion with facts or reasoning when i have continually dis-proven them with actual evidence. you have yet to produce anything other than an ancient google query written by one of my clueless forum members from years ago
3. again stock ls/vtec is wrong so stop using it. how you broke it down is still wrong. get off of it already
4. build a b18b1 to take 261whp? they do that on stock parts. congrats .. on accomplishing the norm
5. no you do not have to invest a grand into an lsvtec in reliability parts. how much do you think rod bolts cost? lmao i thought you build motors
6. and you still don't know what you're talking about anytime you make statements that the "ls bottom end wasn't meant to handle gsr cams"
7. the full version of what is better than the non-moddifed lsvtec. there are three different heads with different results. and lsvtec with a factory ls bottom end and factory b16 head will make less hp than a factory ls bottom end mated to a factory gsr head. so what is the factory variant you're comparing one of the 3 lsvtec combinations with? if you're comparing to a gsr then gsr's only make between 140-145whp. there are a good portion of lsvtec that make that kind of power on the stock cams from the head and stock pistons. where are you getting your data from? lol
8. you did say something about power. the gsr is superior in making end all potential and that the ls bottom end wasn't setup to make power with a vtec head. what the hell are you smoking? for somebody that "builds" hondas you sure make some noobsauce statements. how is the bottom end not setup to make power with a vtec head. how is that even a logical statment?
9 why are you trying to explain compression to me when i had to educate you on compression and cams?
10. why don't you find us a dyno of a ls bottom end with gsr head and post the numbers since you're so sure of yourself

11. please post up pics of you with this "engine" you're building. i don't understand how somebody that is building a "built" turbo engine doesn't understand the basic principals of engine building. "an ls bottom end wasn't meant to make power with a vtec head" yet they make more power than b16's and similar power to gsr's and have more tq than both.. you even claimed the gsr has more end all potential?

Again, WHY DO I NEED TO JUSTIFY AN OPINION IN THE FIRST PLACE?

1. it's not just .1 displacement it's the stroke as well. makes more power sooner. and i just showed you that you can make up for the lower compression ratio. hence the dyno that i have provided.
Even if it does make more power sooner, it's so very insignificant. If it were worthwhile everybody and their brother would be tossing the GSR bottom end out for an LS block.

2. stop offering your opinions as facts. where did you justify your opinion with facts or reasoning when i have continually dis-proven them with actual evidence.
You haven't disproven a thing. You posted a built motor's dyno, which has no merit when referring to stock parts. Even so, the dyno you posted, although close, still made less power then a full on counterpart. Decent torque curve? Still has no bearing when I'm not trying to say anything about power curves at all.

What was yours 180/133? Bone stock ITR, making more power and torque than your "LSV."191whp/140tq

Build the head and throw in cams like your motor, and I bet you it would be even further off.

3. again stock ls/vtec is wrong so stop using it. how you broke it down is still wrong. get off of it already
Never once did I say either of these. YOU'RE spreading misinformation by saying that. I simply said my opinion was that it was half assed. My OPINION. I never once said "It's wrong" or "Stop Using it." Where the f*** are you getting THAT one? For someone who keeps talking about misinformation you sure do make up a lot of crap. And simply because you dislike the guy, does not disprove what he said. You tried saying he was telling people that the B16 was better than the GSR motor.. which he never said, and I pointed out with quotes, not quotes taken out of context and what you assumed they meant. Hahaha. :roll:

4. build a b18b1 to take 261whp? they do that on stock parts. congrats .. on accomplishing the norm
It wasn't built, the only modification to it was ARP head studs- the point was that little old me rebuilt the motor myself. But I know how you blow things out of proportion so I thought I would mention it.

5. no you do not have to invest a grand into an lsvtec in reliability parts. how much do you think rod bolts cost? lmao i thought you build motors
$300 for the kit to actually bolt the head to your bottom end.
http://passwordjdm.com/Golden-Eagle-B-Series-LSVTEC-Conversion-Kit-P3593C581.aspx
$65 for rod bolts, another $120 for head studs, $500 there. Another $100 to mill the head, deck possibly too might need decked you're at $600 just slapping a stock head on- keeping your old bearings, rings, ect.


8. you did say something about power. the gsr is superior in making end all potential and that the ls bottom end wasn't setup to make power with a vtec head. what the hell are you smoking?
I have yet to see a LSV's max power more of that of a GSR. (I'm speaking generally, both being built to the teeth.)

LOL. Oh look, a GSR bottom end. -_-

You see how posting up built motors does you no good? We're not talking of built motors.

for somebody that "builds" hondas you sure make some noobsauce statements. how is the bottom end not setup to make power with a vtec head. how is that even a logical statment?
9 why are you trying to explain compression to me when i had to educate you on compression and cams?
Lmfao, Butt hurt much? You didn't really educate me on anything yet.. and because you seem to be missing the concept of compression when talking about LS/V. Why do you think so many people upgrade pistons when building them?

11. please post up pics of you with this "engine" you're building. i don't understand how somebody that is building a "built" turbo engine doesn't understand the basic principals of engine building. "
You will see the motor as well as a full list of specs soon. I'll be making a well documented build thread soon enough. A few members here have already seen the motor in person. :roll:

10. why don't you find us a dyno of a ls bottom end with gsr head and post the numbers since you're so sure of yourself
From your buddy Jeff Evans himself..

LS/V: 165whp/124tq
LS/VTEC b16a head conversion
b17a cams
itr intake manifold
usdm itr exhaust manifold


GSR: 171whp/138tq

Edelbrock Performer X Intake Manifold


ITR: 186whp/136tq

AEBS intake manifold


(All had 2.5" exhausts.)

There you go, nearly stock GSR and ITR against a stock-ish LS/V. Having trouble finding completely stock motors, nobody really tunes a stock motor... To be fair I did find a LS/V making 192whp/148tq..... with a 12:1 compression, lol. :roll:

Does that satisfy you? I justified my opinion.
I know i'm not supposed to feed the trolls, but I can't help it sometimes. :thumbs up

You can make 260hp in LS motor easy with turbo. Just get ARP head studs and a decent turbo kit and call it a day.
