how far will a 3mm head gasket lower my compression?
if the compression is 10:1!

Im running an inline pro 3mm headgasket, i believe it drops the compression down 1 pt, i could be wrong though.

 

how many psi are you running?

 

i still have to get tuned (hondata) I plan on running 12-14 on 94 and 15-16 on race.

 

right on! what type of kit is it?

 

i don't think that it drops the cr only by 1 pt... i also have a 3mm plate and my cr ist 7.7:1 .... original was 10.2:1

I really doubt that it drops it that much, I think it's around 1pt.

 

If it is a 3mm headgasket that equals .11811 inches, original GSR motor at 10:1 then with this gasket I calculate 8.2962:1 WHOAH! I think the 3mm askets are meant for the ITR motors of 10.6:1 and 11:1 JDM ITR. The 2mm gasket on your 10:1 motor would put you at 8.9624:1 so very close to 9:1. Your sig says JDM GSR motor, if so and no chanes that is a 10.6:1 CR motor.
