id say yes my rb20 has been build for 400 hp at the whells bigger turbo full tune intercooler etc etc all forged internals and been dynod at 406 hp at rear but detuned to run at 220kw only
when i had my workshop i used to use prestige auto electrics cant remember their number but speak to rob he does lots of full re-wires etc only decent one i know
i put a pod filter on a big after market turbo rebuilt the motor it now hammers out at around 4oo hp but i have it detuned atm and it is runing around 220 kw according to the dyno
