RB30_LX

I don't see the headache... Just need to know if anyone has fitted poncams that are supposed to be for r33 rb25det's into an rb20det?

I have an RB25de head (non turbo) from an r32...

I'm running an R32 RB25DE Head... (easily interchagable with RB20 cams) But as the R32 RB25DE head is so low volume- The easier question to ask is; if the pon-cam in my initial post will be ok in an RB20DET head??

Hi All, Wanting to know if anyone has direct experience/ knoweledge on pon-cams.. Specifically if PN# 143021 264/264 duration 8.5mm lift will run in an rb20/ r32rb25de head? They are listed as suitable for R33 rb25det up until '97 manf date. But confilcting info on the web is rife and i cant find a clear answer. - Some say theses cams aren't compatible with VCT in the rb25dets that they are listed for. (Thus making them quite suitable for the rb20dets).??? this may be BS?? I am looking at these cams for my rb30det build (using r32rb25de head), but not sure if these would be compatible with CAS etc. Thanks for any help-
