From our Australian friends.... A long list of different builds and the results from the dyno:

Interesting point of note, it appears that many are running the stock un-tuned ECU on aftermarket turbos & mods, upto around 170-180 rwkw.

Stock injectors with stock fuel system is more like 160-170rwkw, but can be higher with bigger lph fuelpump, adjustable FPR, tune to suit. X those figures by 1.341 to get hp. At factory the 270cc injectors are near on 100% duty on some parts of fuel map.

160-170rwkw (around 168rwkw) can be done with ECU tune, 3" exhaust from turbo dumppipe back (front pipe, catback exhaust with no cat), hybrid stock RB20 turbo.

Stock engine can produce up to 330hp at engine at 14.5psi / 1bar (190-200rwkw) with FMIC, boost controller, ECU tune, injectors, fuelpump, 3" exhaust from turbo back, clutch upgrade.

It is very interesting to see the wide variety of results. Some very high quality builds with expensive engine management are producing only marginally more, or some times less than other builds using eprom and ebay turbos. Truly an artform.
