Do the suspension and brakes first then start on the motor, if you put a motor in the car that makes it run mid-14's the stock brakes and suspension will spoil the fun. You could also upgrade the cylinder head while you build a fresh bottom end. Flat top pistons, cam that pulls from about 3K to 7K and then add good cylinder head. To get the acceleration you want you'll going to need close to 100 RWHP, this is what a full race A12 puts out, so the A14 or A15 will still need to be fairly roarty..............I'd say don't get hung up on a set number just build a good solid street motor, that combined with suspension and breaks will make a fun car.
