SOMEONE PLEASE HELP ME!!!

Ok heres the situation. My borther has a small fifty trim turbo and is going to run it on a stock re-built LS/VTEC (gsr Head). Bottom end will be 81.5mm, ARP head bolts, Cometic head gasket. All tuned with Hondata. So there wont be any issues.

Its a B18A bottom end, but right now we are deabting if he should run, PR3 Pistons or P73 pistons. We are trying to keep the compression as high as possible since we are going to only run low boost on a tiny turbo! 8-10PSI.

But we are not sure what piston to go with yet..

WHAT DO YOU GUYS THINK????

 

Why do you want such a high CP? If you use any of those pistons your going to be over 11.1

which pistons USDM or JDM?

 

USDM, only planing to run low boost, so compression isnt that big of a deal...

Fine tuning on a Dyno!

 

Well i ended up going with the ITR piston, i heard the PR3 have weak ringlands!
