unless your going custom up pipe, you are going to need a turbo exhaust manifold, turbo xrossmember, and turbo swaybar.

you are also probably going to need a better fuel pump, and injectors, and some kind of engine management. and probably a few other things that i cant think of.
someone can correct me if i'm wrong, i'm still somewhat new to the whole turboing an rs thing

(edit) sorry, i didn't see that you said you had a hydra, ignore the em part.

Don't forget about gauges.

Boost, Oil pressure, EGT, and Wideband O2 (For tuning) at a minimum. Don't forget aboput oil feed and return, coolant lines, and intercooler.

Also, prepare to replace a clutch depending on the condition of your existing one.

I believe your car used top feed injectors so that puts you in the market for 440 cc WRX injectors.

Somebody else feel free to chime in on this since I am not intimately familiar with teh 02+ EJ25's
