Rb25det neo head on rb30 block forged piston choice????

[allthewaytotheskyline]

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

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.

Hmmm which gasket are you using and did you take much off the block?

Also which forged pistons were used?

He said completely standard bottom end.
