Hey guys, I am basically going to rebuild my GSR to somewhat ITR spec, I have found an ITR head but it has been milled .10 and I was wondering what this would do for my compression..

basically planning

jdm OS ITR pistons in a b18c1 block
mugen headgasket

I think thats all that would effect my CR ratio, so I was wondering if anyone could guestimate what mine would be around...

 

look at the compression calculator on the c speed racing site

a b16 head is probably going to be cheaper than a ITR head also.

 

Compression calc didnt have anything about head milling, and basically i want the ITR head for the porting and the LMA's...

 

Take .010 off the head gasket thickness

 

im we-todd-did, cant figure the bastard out..

 

nevermind..

wont be purchasing the milled head anymore.. thanks for your time RJ
