i have a boosted jdm d15b vtec and am looking for some internal upgrades and have found out that the vitara pistons are a direct swap into my engine. i am wondering what exact pistons to get tho.. iv been searching for this for a while now and have found out little info on the fitment of vitara pistons into my d15 and was wondering if anyone has done this swap. if so, what year vitara pistons will fit? do they match up with the z6 rods? am trying real hard to build this little guy up right now i am running 8psi at 193whp. and want some better numbers. anyone who has done this swap please post some results or some swapping info..
thanks
