I had a turbo ga. Pretty fun. about $450 to turbo it, running 5psi off a saab 900 turbo charger, eclipse sidemount, sr20 injectors, maxima fuelpump, custom manifold. I say it put out about 160 or so to the ground. Not to shabby for a car that weighs around 2200lbs. Also they dont like to be supercharged lol. But I say make a cheap turbo kit, rag the shit out of it daily. It will keep going. A fun little beater. Now an SE-R I would not use as a beater, those are worth money to invest in.
