RB camshaft question

[sean8564]

What is the Duration on RB20,25 and 26 cam shafts and why can you not interchange the shaft from a 25 to a 26

http://www.tomei-p.co.jp/_2003....htmlrb26 uses solid lifters, so diffrent cam profiling however you can use rb20 cams in rb25s.

Minor thread resurection...

I heard somewhere that you can actually swap the valve train and cams from an RB26 onto an RB20. Don't know if it's true, be sweet if it was.

heh, if it were only that easy.......lifters and springs are totaly diffrent however you can use z32 stuff in the rb20 head no problem.

what about 26 valves onto a 25

[eh?]

No, different valve lengths
