I have a B16a bottom end and i was just wondering what OEM pistons make more compression?? JDM CTR or JDM ITR pistons??? Thanks

 

both will give higher compression but the CTRs (PCTX pistons) will give more than the ITRs though. I'm not sure on the ITRs but if you're planning CTR's you're going to have to modify the b16 connecting rods to fit (1mm of each side of the rod), so a trip to the machine shop is necessary.
