Aveman This is a solid kit, the car pulls HARD with it. I sold my car and bought a e30 to turbo after being in this car. I'm sure he could work out a good price installed. You'd be in STI/350z category with this kit installed, at 8 psi. With good engine management you could bump it up a few more psi.
I have a video of racing my racing my buddy's modded G35. I pulled about 4 car lengths on him.
