Swap S2 Ex. cam into NA 20V ?

[coolhand]

Hi guys, I've started the engine rebuild trip and want to put the NA 20V ex. cam into my S2, but does anybody know if its o.k/safe or otherwise detrimental/unworkable to do the opposite
The reason I ask is because I have in my stable a daily driven 90 20 V and thought that it would be ideal if I could simply swap out cams between the two !
Saving money and gaining the timing benefit for the S2....and hopefully not having too serious an impact on the 90's performance.
Any enlightenment on this would be appreciated

It probably has serious impact on the 90.

From what I understand the 7A cam is higher lift too, so you gain benefits from increasing exhaust flow to the turbo in the S2 ...but if you put the lower cam in the 20V I think it will compromise performance significantly? Might see an improvement at the bottom end but I can't imagine that it is a wise move. Anyone with more experience on this care to confirm or otherwise?

NM cam is different to 7A

Mmmm....I did a search on cams here and dug out a quote from the timing/mapping man himself ...Minhea, stating that it's no problem and in fact might tame the peaky response on the 90, but still seeking more feedback..ANYONE actually done this out there ?????
