Tomei Pon-cam Question

[RB30_LX]

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-

So which head are you going to run? Rb25 or Rb20?

And I presume it is not a n/a head you are thinking of....

[RB30_LX]

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??

[r32-25t]

The rb20 head will be a nightmare to try and make it work

[RB30_LX]

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

[Hadouken]

mate this will be a headache

[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?

You need to sit back and realise what you're asking.

First you say you're building an RB30DET using an R32 RB25DE head and want to know if R33 Poncams will fit. Then you're asking about it going into an RB20DET.

What do you want to do? Put the cams in the RB25DE head or RB20DET?

What he's saying is that the cams from an RB20DET will go into the R32 era RB25DE head and vice versa. After that it gets confusing.
