what head gasket for boosted application?

i've been doing a search on here but i havent found any advice on what head gasket to use for a boosted application.

got an h22 with a t3 greddy turbo, unsure of the size or any of that. so what kind of head gasket should i be looking at? how much boost is it good for? thanks!

Alex

Cometic Gasket, Inc. i know they make exhaust and main seal gaskets, unsure about head gaskets, tho I'd really like to say for a fact they do.

Re: what head gasket for boosted application?

a regular felpro gasket from autozone or some place wouldn't do??

Also, do i want some specific type of rings or do stock rings work well? i have JE pistons in darton sleeves with eagle rods

I'm sure it would hold up fine, but since your tearing apart your motor anyway, might as well invest in something better then what your using now. And I'm not sure thats not really a question I can answer. Google h22 turbo piston rings or something. Or see if JE offers rings that fit the pistons you have.

Re: what head gasket for boosted application?

just go with OEM rings... and im not sure if cosworth makes a HG for the h22 but ive never heard one bad thing about them and i run it also.. but ive heard some different opinions on cometic HG....now why would you even consider going with an autozone HG before going with an OEM honda one

btw i run cosworth on my sr20

and u say u have pistons well what C:R are they... stock or lower... if they are stock go with a little thicker one if not stay oem specs

dont cheap out using autozone **** or you wont have a motor that runs for long

Re: what head gasket for boosted application?

I thought the thicker the gasket the lower the compression, since your running turbo prolly should be bigger. but idk i thought i heard that somewhere probably here

Re: what head gasket for boosted application?

considering I am the only guy boosting an H22 to reply yet, I think I'd listen to me over these other guys... I also know a little bit about motors and the a tad about the h22.


Rings... Dont use OEM. If your not running OEM sleeves, OEM rings are not your friend. You shoulda have been able to purchase some rings with your pistons... Also, upon purchase of rings, make sure you buy a ring end gap file. Your going to have to file the rings to the appropriate gap. You'll need a feeler gauge to measure this gap as you do it too. If not done right, kiss your motor goodbye...


HeadGasket... Use OEM or cometic for boost. OEM works great as its high quality MLS gasket. Several guys (including me) are pushing over 600whp on a stock one. Cometic makes great gaskets too. They are the better option if your looking for a thicker application to lower your compression or if you need it because your clearances are shot. But, they are just as good as OEM in every aspect.

Re: what head gasket for boosted application?

We use oem honda gaskets on all our builds, even the 700hp d-series we are working on. Like stated above. The OEM MLS is a great gasket to use in any situation.

I can hook you up with one too, just let me know

Re: what head gasket for boosted application?

x2 We pretty much covered it... It sounds alot more technical though, lol. My dad has stock gasket with a t3 turbo pushing 10-15psi without problems.

Re: what head gasket for boosted application?

i bought the motor as is, the previous owner put the forged internals in. spoke to my machine shop and they told me they can probably resleeve that one piston with a new dry darton sleeve. have to bring them the bare block with one piston so they can use to measure and whatnot.

only problem is i cant get the damn crank bolt off, even with my IR impact wrench.

im stressin the f*** out after reading all this piston ring gap and all, seem like im in way over my head. i don't even care about a turbo right now i just need a daily driver :/
