    Even fully built ej race motors do not handle nitrous with any amount of reliability.

    Just to be clear, you do know that it would be much cheaper to just sell your car and buy a WRX or STi than trying to build and turbo your car?.. you're going to need to replace pretty much everything, including wiring, ECU, transmission, etc (if you want it done right).

    Yeah just like ej257 said, it's pretty much a lost cause to build a 2.5i into a custom turbo'd wrx clone... It'd very quickly turn into a money pit... If I were you I'd either trade up or if that's not an option, put on some light bolt-on's and do some suspention upgrades with bushings, short shifter and build an auto x car... They also do sell better camshafts for the 2.5i that they claim will give you about 20-30bhp increase with a tune which if it's correct with cams, catback, intake, and tune you MIGHT be at around 200-210ish horsepower at the crank... Just food for thought, but I'd look into it more though...
