ok, without slammin u for sayin 15 psi on a fmax turbo, u should be more specific(a/r, all the specs of the turbo and such) if u want real good answers, but heres my opinion JE pistons (low compression lik 9.0.1), rods(crower), since it is a H series, find out wether urs is open or closed sleeved, if u dont kno what that means tell me and ill tell ya, but i dont wanna type it all out if u already kno, either way its always smart to get it resleeved...but not always necessary. anymore questions let me kno
ps- i almost forgot, before u upgrade anything buy hondata for turbo h23, and ull be set, hondata is better than internals and would be the first thing i would do if i were u
