LQ9 short block, LS3 heads, LS3 intake, 1 7/8's headers and either TD's or a 3.5" I pipe and cut out, and a custom 23x/24x cam. You'll probably need something close to a 4000rpm stall converter and wont break 500hp but might get you close, what do you expect from a budget setup and a stalled auto.

Better flow, but at the cost of low speed torque do to the loss of port velocity. If your car was a M6 ported cathedral heads would give you close to the same power and better low speed torque but a A4 with a stall converter doesn't need it. Another reason is the LS3 intake flows close to the same as a Fast 92 and can be bought new with injectors, fuel rails, and DBW TB for $500, you can't use the TB but you can sell it for $100-150.
