there are mods for it, i think toda has got forget pistons that raises the compresion, there are cams but vvti has to be unplugged, but dont think these mods will get your car going faster than a supra. the more NA horsepower you get the more undrivable the care is going to be on the street, on the track is a diferent story. If you want it for the track there are billet and forget components at http://www.trdparts.jp/. For the street my recommentdation would be 260-280 degrees camshafts on both the inlet and exhaut,my cousin has got this setup on his corola, dont forget about the ecu and the fuel pump
