Difference between USDM & JDM ITR Pistons
I just want to know the difference between the two, because the JDM yeild a slighty higher compression, why is it?
DO they have a higher dome?

well the JDM P73 piston's part number is: P73-00
US P73 is: P73-A0 ("a" I assume = american)
Dunno the actual heighth specs but these images help show the differences.
JDM ITR piston (P73-00)...

Perfect that is what I was looking for!
So the bigger dome raises compression. How big of a compression difference is there between the 2?

well US ITR engines are rated at 10.6cr, JDM ITR is rated at 11.0cr, so approx. .5 points higher w/an ITR piston.

Re: Difference between USDM & JDM ITR Pistons (Katman)
Okay, Another question. Is it a good idea to use pistons that were previously used before, or can you buy after market ones, and if so who do you recommend.
