The next one up from my 7064 fits the same housing and will allow for 580bhp if I go for the 2.2 Ally block...this is Marks estimate and he is normally right on the money.
Ain't 7064 and 9180 the compressor and exhaust wheel diameter sizes in mm?
What I mean is they come with different exh housing options so for example would 500hp yb on a 7064 be on a .82 exh housing and say a 700hp yb like Mark Hudds be on something like a 1.05 housing?
