not sure exactly what turbo is on the rb20.. i pressume its a t28 garret with perhaps a ceramic turbine? if thats the case then you will be limited to around 15psi, however to run that safely you will need to at the very least upgrade your fuel pump, maybe also injectors and either get a piggy back unit to control fuel or maybe something like a chiptorque chip or unichip to control both fuel and ignition maps...
with that turbo i dont think you will get more than say around 140kw's @ the wheels, assuming its the t28 ceramic which also come off the vg30's...
figure out what sort of power and drivability you want for your car and then select a turbo based on that.. basically whateva turbo upgrade you do u need to upgrade the fuel and ecu as well 
a nice turbo would be maybe a vf30 ihi or maybe even a gt28 off an s15 (rated @ 280hp @ 16psi or so), both will start boosting earlier than mine id imagine (vf22 boost starts at 2500rpm compare to stocker 2200rpm or so) and both turbo's will be able to get you around 160 - 170kw's at the wheels with the right tunning and setup

It's a great turbo when turbo charging lightly in that I mean 10-12psi as it is in it's peck range and was built ot supply 10psi from factory to the nissan six
It's fault is the Ceramic turbine this means it's limited to about 14-15psi thne if overspun could shater in you exhuast, this can be replaced but by the time you do hi-flow better off in first place buying a HKs or newer aftermarket garret version
They are whatI call a mixed between T28 and older T3 they look like a T3 but act more on a T28 which Ithink from memory is what they are.

Hey Franks,
The stock injectors will be able to provide enough fuel quite easily at the suggested boost levels for that turbo, you will definately need however a new fuel pump, a chip will provide further gains as well.
The positive thing about that turbo is that i believe it has the same flanges as the new gt28 turbos, if thats the case then you will be able to upgrade to an s15 bb turbo capable of an easy 280hp, when/if you do take that option sometime down the track then you will definately need to upgrade the ecu and injectors
