no i know about boosting itrs... but i just didnt think that a stock gsr block with just a b16 head would sky rocket the compression like that. just have a b16 now with gsr tranny. just wanted to put a 1.8 bottom end on it. but i think a thicker head gasket would lower it to the 10s? what do u guys think?Originally Posted by xPhantomSilviax
