First thing I did was a turbo back exhaust and 12psi boost increase.

I then threw on a fmic and pushed boost up to 1bar, at this point my fuel pump fell over and couldn't keep up so on went a bosch pump. I found from 12psi to 15psi peak power didn't increase all that much (~12rwkw) but the mid range was a hell of a lot more lively.

Mine ran that for years then eventually I finished off the new motor and dropped that in.

Unless your going to throw on a larger turbo I wouldn't bother with an ecu remap or aftermarket ecu as the turbo is out of airflow anyway so there are very little gains to be had (unlike the r33 in the same situation)
