guys, ive bought a built rb30, its running forged rods, pistons, race bearings +b/e bearings, but this block was using a RB25NEO head. So comp ratio will be around 8.4:1 with NEO head, 7.9:1 with R33 RB25 head.
and now im going to run an rb26head. ive etimated it to be about 7.8:1 with a 1mm head gasket, should i raise it? or what should i do? how could i make it higher?
or what does this mean? can i run extreme amounts of boost? is it gunna drink fuel faster than i can piss?
