My RB30E made 109rwkW on a dyno, it's standard with GTS1 cam and GTS2 extractors.
Dropping $10k into it would easily make 250rwkW Do it hero, and post results (so we can laugh at you). By the time you're done, you could have bought an RB25DET.
You came here for advice, you got it, you don't like it so you're going to fight us? Kids these days...
