    I need a new map sensor and the boost by gear solenoid before I up it, but hopefully later this summer. My wife is in nursing school, so we're trying to save as much as we can right now.

    The car is still running like a champ though. The other night, I was coming home from a local meet at 1:30 in the morning. A C6 (non Z06) wanted to play on the highway. We did 5+ pulls and it pulled hard on the Vette each and every time, even when they got the jump on me. 60 or 70 to 120.

    If memory serves me correctly, from this forum back when I had my 1st ep, back in 06, I'd read that one of the weak links in the a3 was the oil pump, which can't keep up with revs above 6900 rpm. Its a problem unique to the a3, and it doesn't take much imagination to come up with the list of problems that can cause

    The oil pump is the same as the A2 so Iím pretty sure it can keep up oil pressure at those RPM. Donít believe me, get part numbers for both model cars and you will see that it is the same.

    I got a stock k20a3 turbo making about 275HP at 15psi of boost. Issues that arose was stock clutch and stock fuel system limiting the Potential Horsepower that it could make. Changed to stage 4 clutch and now have a return fuel set up with regulator to run E85 with injectors and fuel pump. The HP gains per pound of boost is about 7.6, my set up is rated for about 300-400 horses before I run into turbo problems, but for the build thatís plenty. Raising boost to about 25psi and adding E85 which is automatically a 50HP gain in most cases. The car would make about 400 theoretically. Or use 5psi less and be at 20psi and be about 360HP. Sounds realistic to me given what the car has achieved already, and having cooling properties from running E85 letís hope the engine can last.
