Okay so i've been looking into going all motor. I was looking at a set of RS machine pistons for my GSR hatch. I'm just doing pistons right now with stock rods and stock valve train. I eventually will upgrade the valve train.

I've looked around and couldn't really find anything that would lead me to choosing one or the other, the ITR's or PR3's. I know that the PR3's are JDM spec and would yield a higher C/R than the ITR's. But the ITR's come with the Teflon coated skirts. I was thinking about going with the PR3's b/c of the higher C/R. so my question is which pistons should i go with the ITR's or the PR3's?

also i'm not sure if i would have to do any modifications to the ITR pistons to fit onto my stock GSR rods. I know that with the PR3's i wouldn't have to do any modifications. so the question is would i have to modify either the ITR pistons or my stock rods to make them fit?

another question: would i have any problems running just the pistons and not upgrading/modifying anything else... ie: ecu, valvetrain?

any help would be greatly appreciated. and i'm sorry if there is already another post on this but i couldn't find exactly what i was looking for!
