if your still interested in a vr-4, my friends dad just picked one up from auction.i think he's looking for somewhere around 4,000.if you want i can get more info and pics for you.
and i agree with SR20, i dont know many people with boost controllers that keep it at stock boost.but i know you and your car so im sure you'll know what to ask.and can we assume this one will be as clean as the ka-t when you get it.
