RB26 - hp and reliability?

[[SPESHAL]]

I've bought an R32 GTS-t with an RB26, has a T61, HKS 272's, Wolf, etc, makes 470 rwhp @ 18 psi with stock internals.

What is the maximum, reasonably reliable, hp that a stock internalled RB26 can make???

Any weak points that can be addressed - the oil pump yeah??

Cheers

GOTBOOST has been a very tough package for a while and has no signs of stress.

Its got a soft tune in it so i feel you will get a good run out of it if you dont crank it up.
