What rstdave is saying is right imo, mines mapped for about 2 bar but as it's still a std bottom end (and gearbox) it's turned down to 1.5 bar. I don't think it would take sustained thrash at a trackday at 2 bar
and i think that's about the limit of the turbo?

PF Nick's car was a standard bottom end and that went on for a good while with similar spec

Mines similar spec, L6 weber management, TT stage 3 t3, stage 3 head and old PE SX428 cam and did 243bhp at 1.5 bar
Also did 219bhp at similar boost (16psi)

consistent figures
