Hey guys, I'm putting together a B16A Turbo setup. I thought I'd get a Cometic head gasket while I had the head off. What thickness would you guys recommend? I am aiming for 250-300whp. I have TT Rods and SRP Turbo Pistons. They have .030 in 81, 81.5, 82, 83, and 85mm available on eBay. What do you guys think? Thanks in advance!

 

i think you should get a stock oem head gasket.

 

i put a cometic thicker head gasket on my boosted stock b16 thinking it would be good and my tuner told me after the fact that i could have gotten more power with a oem gasket ...so i would stay stock man

 

If that's what you guys recommend I think I'll go that way. Because I already have a OEM Head Gasket set. Would the OEM head gasket handle 300whp?

 

The oem gasket is just as good as the Cometic.Some people prefer the oem over the Cometic anyway.If you already have a dished piston than the .030" thickness is good.If the bore is 81 to 81.5mm than you want the 81mm.

 

I ran oem all year long in a nitrous motor spraying anywhere from 100-250 hp at it on top of the 210 it made on motor. No issues at all with OEM.

I have always used them in both nitrous and turbo motors with 0 issues up to the 500whp range.

 

ya just go with the oem

 

I need one to get low my compression with my old set up(nitrous- 11.5 - 1) Just change the OEM gasket to cometic 70mm w/o change my internals and run turbo with 25 psi...
