Difference Between Rb25det Series 1 And 2 Cams

[13thracer]

quick question what the difference between rb25det series 1 and 2 cams are they interchangable

[MsG_ChRiS]

I would think that they would fit i think it would be the ones from the NEO RB's that wouldn't.

but would there be a reason to change to them anyway...

its not like they would give much of a boost in performance ...

are you building an engine or something and you can them cheap?

the cams changed in the R33 RB25 after September 97

before that date are S1 cams, after are S2

i have a set of hks cams for a series one laying around and am looking at buying a 33 in the near future so am wondering if they could be fitted to a series 2 engine if i ended up buying a series 2 33
