Hello guys,

buying a forged domed piston for my 318. It will run on a 250 nitrous shot.

Which one would you buy if you were me...

TRW WL2329F30 - http://store.summitracing.com/partdetail.asp?part=TRW%2DWL2329F30&autoview=sku


Main differences arethe ring size. KB is 1/16 and TRW is 5/64.

Both will give me almost 12:1 CR.


No much infot for the TRW.
