Assuming what you have is healthy, you will be limited by fueling, you will be running rich if you turn up the boost, but with a well setup Apexi S-AFC or similar, you should then see around 275fwhp at 0.9bar.

At 1bar you may even see 300 on a generous dyno. But the ceramic turbo won't last long.

You will get a little more from the RB25 turbo but it is a little more laggy.

For more than 300fwhp (geniune) you really need your turbo rebuilt in steel, a tunable ecu (something like Nistune would be fine), some bigger injectors and a fuel pump.

there's a great thread on skylinesaustralia.com with dyno plots for all sorts of level of tune for the RB20.
