Intrested in this power as its probably all I could afford if I ever venture back to cossie ownership

well in my personal experiance i always run a re-shaped / ported head for any cossie engine spec but again a .63 T35 hybrid should run (HELD) 24psi and produce 400bhp on a well fuel`d (400cc/min+) healthy engine.
P.S 2 BAR is 29.4psi (14.7psi = 1 bar) thats a lot of boost for a turbo like that, expect a very very short life out of the turbo!
