motor build for turbo. need info

NO! You cannot reuse stock headstuds. When the headstuds are in and torqued they absolutely DO stretch. It is recommended by everyone EVEN HONDA DEALERSHIPS that you DO NOT REUSE HEADSTUDS.

I would just run ARP's

Look dude, they are not stretch bolts, they are just head bolts. If torqed properly they should not stretch. Plenty of people have reused bolts over and over again without any problems. So yes you Can reuse head bolts. The dealer wants you to buy new ones so they can make some more profit off of you.

 

[AlexD]

All head bolts will stretch to some degree, with the OEM ones more than ARP. Stock OEM Honda ones do stretch, thats how they are whether or not you choose to believe it. Go call your performance or tuning shops, look it up anywhere you want, and even ask them if they recommend using stock head studs over again for performance builds.

If you want to reuse your head studs for your daily driven grocery getter civic i dont see the issue. But the fact that you are condoning the reuse of stock head studs on a boost build is ridiculous, and will only lead the OP to future headaches, frustration, and a lighter wallet.

OP, get the damn ARPs and be happy.

Well his vehicle isn't boosted. As I stated earlier for motors that will have higher clyinder pressures you will want to upgrade. For stock motors with bolt ons it is ok to reuse the bolts if they are in good shape. If the bolts came off a normal motor they should not be stretched. An easy way to tell is to take a die that matches the thread pattern for the bolt and run it up the threads. It should not cut into the threads, so if you are getting metal shavings while using the die (assuming you have the correct pitch die) your bolt is stretched and needs to be replaced.

 

[AlexD]

have you read the thread title at all?

Heres what I want you to do if you dont believe me. Take stock honda head studs and measure them, put them in the motor and torque them to the correct specs, run them for 100,000 miles and take them out. Measure them again, and tell me that they do not stretch.

Honestly if you talk to anybody who is knowledgeable in building ANY motor, and you tell them you plan on reusing your head studs for a boosted build (once again, the title of this thread is....), and they might giggle a little bit.

Heres an example, ever wonder why high hp builds go with arp bolts or similar? Because under that type of force, oem honda bolts will stretch, and it causes the head to lift, resulting in blown head gaskets.

This is what happens to metal when its exposed to heat and pressure, especially over long periods of time and use. If you think an oem honda head bolt isnt going to physically change at all or stretch over its lifetime you are unfortunately wrong.

Ever held an ARP head stud up to an OEM head stud? Youll notice the ARP headstud screws into the block, you tighten that down, and then you put the nut on and tighten that down onto the bolt. This way, when the bolt stretches, it sits on top of the nut instead of stretching into the block like the OEM headstud.

Whatever dude, I'm not here to change your mind. If the bolts are ok reuse them. If you want to play it safe buy studs. What the hell do I know, I've never built any motors before.

Ok some one hasn't been reading. Im not asking about head bolts i know i need arp head bolts plus the boost i want to run arp is min. I was asking about main studs as in crank bolts. im going ot get brand new oem crank bolts anyways. Thanks for every ones help. I got my plan down for the hole build just need to start buying parts now.

plan

cp 9;8to1 pistons witch should put me at 9;4.1 best i can do with cp 81.50mm
manley rods
AEBS/Professional Products intake manifold
oem main studs
cometic gasket set with headgasket
gsr cams
type r valve train
arp headbolts
acl race bearings
type r oil pump
gates racing belt
1000cc id
golden eagle block gaurd

turbo kit by godspeed
turbo by preiscon 57 trim
hks bov
tail wastegate

ecu
aem ems series 2 with meth kit and all sensors

goal as of right now 350 whp with the option of 450.

thats my build i got a b18c block on the way right now

This is going to be a sweet poor man's type r

what dose most people do? reuse or new oem?

You can reuse everybolt in the motor, even the headstuds.

Been reading?

Where'd you come up with that parts list?. It doesn't seem appropriate for your goal. Maybe you should talk to a shop before you start purchasing parts you may not need. Just sayin, but hey what do I know.

 

[ssmokeyy]

what parts don't i need? I have picked each part for a reason. This motor needs to last 5 years min.

 

[Aussie]

You buying all these expensive parts isn't going to make the motor last any longer. I can make 400hp on a stock block and have it last 5 years if taken care of.

Unfortunately "if taken care of" is up to the owner of the car.

Build your block if you want to go out and abuse it without having to worry about whether or not youre going to throw a rod.

400whp on a stock block isnt anything special, people are in the 500s and even 600s on stock block.

But the question is how long its going to last under the abuse.

If you think a stock block with an identical setup to a built block with forged internals sleeves or not is going to last longer, youre dead wrong. And im talking identical down to the amount of honda bond and tune.

Im going to respectfully disagree with your view on how long parts will last.

If I use better quality parts, put together by experienced people, tuned by experienced people, it will always last longer than a stock block under the exact conditions in which the car is driven in etc.

You wont change my mind because you are wrong and you refuse to accept it.

Can stock bolts be reused? yes. Is it recommended for what the OP is doing? absolutely not.

The path you are recommending the OP is only going to lead to problems with his car, and I dont understand why you refuse to accept or are oblivious to that.

But what the hell do I know, I only own something similar to what the OP is trying to build.

Feel free to talk to a shop about head studs as well "dude", and ask them what they recommend for a forced induction build.

plan

cp 9;8to1 pistons witch should put me at 9;4.1 best i can do with cp 81.50mm stay 81mm if possible and break in the motor under boost
manley rods great choice, I wouldve went with manley if I could start over
AEBS/Professional Products intake manifold a skunk 2 or blox intake manifold would work fine as well, if you want a different manifold, I suggest the victor x for power up top
oem main studs
cometic gasket set with headgasket OEM ONLY, screw the cometic
gsr cams
type r valve train not needed unless youre uprading cams, if you do, go ITR cams best bang for buck
arp headbolts yes, thank you.
acl race bearings
type r oil pump all integra oil pumps are the same
gates racing belt good stuff
1000cc id good stuff as well
golden eagle block gaurd no block guard is the best block guard, skip it, dont even.

turbo kit by godspeed skip this and find something more reputable, save your money if you have to. Making rushed purchases and decision is never good. never settle for stuff thats sub par
turbo by preiscon 57 trim
hks bov
tail wastegate

ecu
aem ems series 2 with meth kit and all sensors meth is not necessary, nor is the AEM EMS. There are several EMS systems that will do a good job for less or for free. You stand to save yourself hundreds by considering these options

goal as of right now 350 whp with the option of 450. obtainable with pump gas, 450 is going to be a stretch for your setup with that turbo. Go with a bigger turbo and a better manifold and 450 will be more feasible

thats my build i got a b18c block on the way right now

This is going to be a sweet poor man's type r

Ive put my 2 cents in.
