i want to up the cr a tiny bit, i've heard the spoon/mugen head gaskets will raise the cr by .3, while the jdm itr already has 11.1:1 cr, adding this head gasket will give it 11.4:1. im not planning on upgrading the cams or valvetrain so i was wondering if adding a bit more comp will be worth it. is 11.4:1 too much for the stock itr head or should i just leave it alone, 11.1:1? thanks in advance.

 

.3 is not worth pulling the head.

stock JDM ITR is 11:1 BTW.

 

i always thought it was 11.1:1. can anybody confirm this?

That's what my B18C6 is and it is the same as the JDM B18C.

 

u guys know your arguing over a 10th of a point of compression. lol basically no diff.

No really though, i always thought it was just 11:1 but i cant confirm.
