alright guys, i've tried searching and didn't really come upon much. maybe im just using the wrong key words of something. lols.. im doing a mild gsr build, i've gone with usdm itr pistons with .25mm OS..(block has already been bored/hone) ive read/searched of a few guys using OEM factory size and with good results..(compression,power, reliable) factory only calls for one part number only, of as i was told from factory..

my question is.! what do you guys recommend i go with and what option is there out there for me..? im sure this question have been cover several of times, numerous .. ehehe.. but now its my turn.. :D

thanks gUys.!

 

im leaning towards oem hg but anyone.?

 

OEM is good for at least 81.5mm
Felpro from Autozone is also a good alternative if you can't get OEM right away.
