ok my rb20 one is farked and i need a new one, ive been looking at all sorts of RB's for them, basically my Q is, whats the difference between the unit for each engine, is there any?
like i said i need one for an rb20 and have looked at non-turbo rb20 ones and ones off rb26's but im not sure which ones will suit, should they all? or are they all different units?
btw, this is the part here, its probs called something else aswell.
cheers
