i just bought a stock head gasket for my gsr that has ctr pistons in it...
you think itll hold up or should i get another one??


and yes i searched =P

it will hold up but i hope you are planning on race gas cause your compression is gonna be up there a lil ways

neeks

err i was hoping on 87 octane @ rotten robbies =x

87 Octane + CTR Pistons = Detonation

dammit!

ok so its safe to say that the stock head gasket will be cooL as long as i use premium gas...

buuuuuut in the long run itll be cheaper to buy a thicker/aftermarket head gasket and spend a little less on gas...

so which one would you recommend?

thanks for your replies btw

CTR's in a GSR will yeild around 12 to 1, with a stock headgasket, your best bet would be to run ITR's which yeild about 11.4:1 but you'd stilll need to run some good gas, aren't stock GSR's suppose to take like 89 or higher?

he should read the post about the compression ratio of ctr pistons...its right on top in the all motor forum...if i remember right the compression ratio with ctr's and a p72 head is like 12.5 or higher

a stock head gasket will work.
If you want to lower your compression a little, try a thicker than stock headgasket by Cometic.
