Compression for turbo

[Spawne32]

blox intake manifold for 800hp :rofl:

I think you need to re-evaluate the 800hp goal because that puts the build in an entirely different class. Do you intend to make 800hp on pump gas?! I dont know anybody making anything close to that much power on pump gas in a Honda. In the Evo world, those guys love big power on pump gas but they do it with uber low compression - 8:1. And they also have more discplacement too.

You will need better rods than off the shelf Eagle H beams with upraded rod bolts You def need to upgrade the wrist pin too and you will probably want to go with a stronger custom piston. You will need a main girdle for the b18b block with main studs.

Clearly you will need bigger injectors and twice the turbo - But you already know that.

And AEM COP wont work with Hondata. You will need to use the Hondata CPR with the S300. Or go with AEM EMS to use the AEM COP.

Not to mention the fact that the BLOCK itself isnt capable of withstanding 800hp even with sleeves. The main's cant hold it for very long.

Alright, well that's why im checking on things before I buy parts. I want to make sure I get feedback from others who have done this. Obviously it's not a common thing for me to build engines for turbo which is why i'm doing the research now. I thank everyone for the input. What would be a more suitable build for 500 or 600 hp then?

 

[Rayda9]

Thanks for the info though Muckman, The more info the better and i'm just looking to learn on this. How can I build a strong turbo motor without learning right?

 

[Spawne32]

500-600 is a much more reasonable goal, and very much attainable on pump gas alone

I could live with 500-600. I don't need anything too high if i'm going to keep it halfway streetable. I just want something more than what I got and for a while I was driving my dad's friend's old Chevy II Nova which had 1022 hp 965 lbft torque to rear wheels. So to me, the teg seems kinda slow. But I wasn't the one who built the Nova, my dad's friend was. Anyway, on topic again, lol I would like some suggestions on parts seeing how i'm slowly inching my way closer to the engine build.

for 500hp your parts list becomes alot more sensible now...

Wiseco pistons 9.0:1 (or 9.1:1 comp) which come with the piston rings and wrist pins
piston choice is purely preference, wiseco and cp are typically 2618 forged aluminum, which will require a piston to wall clearance about .0040 to .0050, where as piston manufacturers like supertech use 4031 low expansion forged aluminum alloys which require less piston to wall clearance.

Eagle ESP H-Beam Forged Rods for B18A1/B1
eagle H beams are good for up to 600hp on paper, but I tend to feel alot safer using a name brand like manley for rods. I dont even trust my crower H beams up to 500hp to be honest, just because i know the core product is made overseas in china or taiwan

Darton M.I.D. Wet sleeves
MID sleeves are not a requirement, you could just as easily run something like LA sleeves which are open deck

Micropolished and balanced stock crank
stock crank is internally balanced, and will rarely need to be balanced again, chamfering the oil holes on the rod journals is a much more effective investment

BC Stage 2 Cams (boost spec obviously)
GSC makes a much better turbo profile cam, consult muckman on this

750-1100 CC injectors (Still researching)
your going to want something in the 1000-1500cc range, injector dymanics or fuel injector clinic will do the job nicely, stay away from GRAM's and RC injectors.

Blox Intake manifold and throttlebody (68mm)
no complaints here but manifold tuning for where you want your power band, will be critical, runner length and plenum volume is to be considered here

AEM COP kit
ACL Bearings
ARP Bolts/Studs all around
OEM Thermostat
Mishimoto Fan Switch
Mishimoto Z-Line Intercooler
Greddy 05H-18G turbo
Hondata S300

the rest is all relative to your preference, turbo sizing, GTX32 or GTX35 equivalent would be I think the appropriate choice for a turbo.

Great info, much better than I anticipated. Thank you for that, I appreciate the help. The only reason i'm going with the Greddy for now is because I got the whole kit for next to nothing from a friend who wrecked his teg bad. He was parting it out, and I got his turbo kit off his b20 (which someone else bought) so for $175 working the turbo kit was mine.

Well your welcome to see how hard you can push the greddy turbo but i dont know that its going to make anything over 400hp.

Oh, trust me, I kno. i can only get a max of 14 psi out of it from what the factory could tell me about it. So i'm not expecting to make over 400 hp right away. I know for a fact later on that I will need a bigger turbo to make my target hp but right now that turbo will have to do. Once I save up I was thinking about getting a Garrett of some sort but not sure what yet, still got some other factors to add in.

I don't log in enough to properly keep up with this discussion- so I will throw some food for thought out there as far as the goals go.

What experience do you have with high horsepower cars? A stock Integra goes anywhere from 110-160whp. 300hp is a whole new beast- which is probably faster than you think for somebody used to mildly built cars. You shouldn't set an 800hp goal if you've never even seen 300hp. 800hp isn't very streetable at the least. Not only running race fuel to get that number you also have to imagine it will be quite a bit of power for the roads. If you're building a car specifically to be towed to the track it's not a big deal.

Are you going for bragging rights here, or do you actually have a plan in mind? 600hp seems like a good number, but it may be way overkill for the average Honda owner.

I wouldn't be going for bragging rights one bit, and from stated before I was used to a supercharged Chevy II Nova which pumped out over 1000 hp. I'm not used to building hondas too much but if you take a look back a bit in the threads and all the advice people had been giving me, I have decided on 500-600hp. As for being towable to the tracks, that will be impossible due to me not having a truck or trailer and I wanna be able to run 93 octane pump gas anyway. So there's been tweaks to my plan so far, but before I buy parts im still looking for more info on what a good solid but powerful build would consist of.

What clutch are you planning on running?

Don't get me wrong, i'm not trying to steer you away. You may be the first one asking about it that has prior knowledge on the topic. It's not often you see people who join saying they want 1000hp- who's done research. Lol.

Spawne and Muckman probably have more information on the subject than I, so I will tip my hat to you and wish you good luck on the build. Be sure to post up some pictures of the beast when it's done. :thumbs up
