how much boost can a stock H22 head gasket withstand? - Honda Prelude Forum

ok, let's agree that I mean on a engine that has proper tuning and has been machined properly.

my block is a JDM closed deck w/darton sleeves.
I have ARP head studs also.
does anyone know the break point of the OEM gasket?

I think it will take an excess of 15 psi. Stock H22 gaskets are made of metal.

Woah...so you are the guy I saw at NOPI...Sweet Lude man...I took like a dozen pics because I knew my friends wouldn't believe me.

The OEM gasket is pretty strong. Golden Eagle Mfg. recommends the stock headgasket with there sleeves. The weakest link would be the head studs.

I ask because I blew the Cometic gasket that I had, and I have a stock gasket (new) just sittin around. I just put in the car today, and after careful examination, I belive that It is gonna seal as good as or better than the aftermarket gasket.

hey hustler904, I'm glad somebody saw my lude down there in the no-man's land at NOPI. thanks for takin' pics... that makes my day that somebody else can appreciate my vison for my third gen.

P.S. I also have a fifth gen, another 3rd gen(stock) and an IS300
