start with bolt-ons

You are jumpin' the gun man. First off if it is an A4 (automatic) You will want to get a converter. Then like co.6z28 said...start with your major bolt ons. Full exhaust, intake, ported throttle body...ect.

well thanks for all the help I have found some rings I think i am going to change the pistons also because I am going to be there anyways so why not and I found some bolt on's also. I am now looking for a air box that will vacume up to the ss hood so my hood will be fully operational any ideas where to get one that sucks up to the scoop i know it has rubber seals on the box that when you close the hood they suction up together?

Other than an FTRA you might have more trouble trying to do that.
