Bigg Tim said:An EVO or STI is easier, but it says something more taking a 140hp can and making 400whp out of it.
To get that high, you will need a motor, headwork, intake and exhaust manifold porting and polishing, big intercooler, a TON of fuel and deep pockets. I hope you get it, that would be cool to see more out there.
