Hey Guys, Need a bit of help with with the car.

I own a 2010 WRX, have had a Ecutek, 3" turbo back exhaust and the cold air induction done all thanks to maximum motor sport, giving it a nice 288hp at the wheels.

But i have been told that the next step is to rebuild the bottom end of the motor. , don't exactly have 6k lying around to do this, so does anyone know where i can get cheap parts and labor to come up with the same result?

Also suggestions on a nice set of coil overs and sway bars

Thanks in advance
