Stage one consists of a complete exhaust system: downpipe, de-cat and cat back.(aftermarket elbo gives no advantage on the standard turbo), A front mounted intercooler, a walboro 255lph fuel pump, a decent boost controller and a set of 1 stage colder plugs.
This set up, with the boost at 0.85 bar will see 250 to 270hp on a healthy engine using the standard ecu.
The next step involves a new turbo(there are many options) a larger set of injectors and a mappable ecu.
A healthy RB20 can run up to and even a little above 400hp on standard internals.
If you want anything more then changing to an RB25 may be a better option as forged internals are not a easily found for an RB20.
