Im building my itr motor and i need a Thin head gasket to bump my cr im at 11:3:1 and want around 11:6:1 but cant find a thin gasket for a 82mm bore anyone know of any? I tried searching but no luck only thicker or just oem thickness. any imput would be great ty

 

don't 100 percent quote me on this but my engine builder told me that honda 81mm headgaskets are good up to about 83mm or so. cuz I was askin him for the same reason

 

just wondering, whats special about 11.6:1 vs 11.3:1?

take the middle layer out or I think spoon makes a thinner gasket.

 

because thats the sweet spot for my cams. I was wondering if they can cut it to 82mm? can anyone conferm this. I was going to get the buddy club if I can make it fit a 82mm bore but i asked a few places and said they dont make anything for that. I did however contact someone who can special order a cometic .7mm but how much cr will that raise over stock, stock is .76mm? anyone got any input on this would be great i know some people are running a 82mm bore

 

all oem head gaskets for 81 MM will work with 82mm pistons/cyl.. i've done it several times...

 

ok sweet so would any other work the same ie spoon/mugen/bc?

 

I believe Cometic can make you a Head Gasket to suit your needs, check with them. . .

 

i checked and i could order a custom one and it would be .7mm but thats kinda thick considering stock is .6mm i think. after talking to don i think ill go with a oem and remove the middle or a mugen.

 

PM'ed

 

thanks for the help allmtr. think i got it figured out now. few more parts and she will get assembled

 

Good luck w/ the build
