As far as I know the factory revlimiter is around 7500rpm
and I have read when chipped they can reach as high as

Redline starts at 7000rpm solid at 7500rpm to 9000rpm max.

From what I have read the RB25, RB26, RB30 are better off-
boost than the RB20.

Hope that helps.

The RB20DET is a fun free reving engine but it doesn't produce power unti aroundl 4000 RPM the RB25 has the ball bearing turbo much nicer across the revrange I think.
Oh and if you'd like some info on the RB series engine check out this site,

RB20 loves to rev.
Its got nothing down low at all - but standard ceramic turbocharger makes boost very early (2500rpm odd from memory).
Mine revved through to 8000rpm without a problem - once it starts revving it just wants to keep going

Yes, it has to be the silver-top (ECCS). The red-top (NICS) has variable inlet runners, controlled by a butterfly at the inlet port. Often these butterflies jam open, and the car then drives like a dog.

I've had my RB20DET (relatively stock) bouncing off the rev limiter (8k) in 1st and 2nd (wet road, no traction)
