allthewaytotheskyline Posted November 22, 2017 Share Posted November 22, 2017 Need help finding new correct forger pistons for 9.0cr for new engine build with 25 neo head? What has everyone else used? I know spool do a custom set of cp pistons and also I can order a set off the shelf of cp but they bring comp to approx 9.3cr which ive told you will need to put a thicker head gasked. Any help would be appreciated. Thanks,Bass Link to comment https://www.sau.com.au/forums/topic/472752-rb25det-neo-head-on-rb30-block-forged-piston-choice/ Share on other sites More sharing options...
iruvyouskyrine Posted November 23, 2017 Share Posted November 23, 2017 I have a completely standard RB30E bottom end with a RB25DET neo head and compression came to around 9.2 CR so forged RB30E pistons would do the job fine.
