I have a friend who made over 200rwhp out of an rb30na but he stuffed around for years... The headwork was a piece of artwork - I drove the car once - and was more impressed with my ca18det silvia! All I did to it was get a friend to write a chip, 14 psi boost, dump pipe and exhaust. Trust me, I hotted up a red metor once, then dad and I installed a rb20 det after disappointment. I know a rb25 is streets afead of a red moter 202 - but then again a turbo in my opinion is a good step up again.... 200rwkw isn't so impressive after a few weeks - you just get use to it
