for 1500 bucks i think you can get alot more than a 16g and exhaust. evo16g, evo560's, wally 255, safc, and an intercooler could be had for under 1500 bucks just put on a open 3 inch downpipe.. thats the bare minimum and i guess its possible to make 300hp on that. i would rather do it right and have a better setup though with dsmlink, some bigger injectors, AFPR, wideband, etc.
