are you lookin at autos or manuals? i have an 01 manual and with just a chip and upgraded vp put down 354. i havent put it on the dyno but im sure with just my sticks i got amost 400 out of it. plus upgrades for 24v are much cheaper, depending on what you lookin at at least. injectors, fuel system, things like that. my bother has an 03 and sticks for it are stupid expensive. also auto trannys will not take that much power before they crap out and they dont get as good fuel mileage as standard. as far as room, he does have a little more bein a 4 door, but i can just move me front seats up a litte and have just as much if not more.
