Rb26 Head

[silvio]

Hi guys i'm looking at doing a rb24 rebuild and i was pondering if there was any great improvements in puting a 26 head on her rather than the oll 20 head also are there problems that make it too difficult to even bother with

thanx

why bother just put a 26 in the car

[-_-StRyDeR-_-]

its possible.... but will take quite a bit of moding (oil galleries n coolant dont line up). if you can do allll the work urself, then go for it, if you cant, you'd find it cheaper to just throw a rb26 in there. or better yet, throw a 26head onto a 30 bottom end.

Why would you? The RB26 head has a HUGE combustion chamber (relative to the RB20), so you will DROP compression ratio. The RB20 is gutless enough as it is off-boost, without de-compressing it further.
