Don't do it! stick with injection. If you want more power and noise, throw away the ECU, air filter box, air flow meter, plenum chamber and assorted widgets.
Purchase 1 x programmable ECU (MBE, DTA, Emerald, Omex etc), 4 x intake ram stacks (as long as practical) 4 x pod air filters (Piper X or similar), air temp sensor and throttle position sensor.
You can use the standard throttle bodies and linkages, crank position sensor and water temp sensor.
After fitting together you can play to your heart's content with fuelling and ignition either on a rolling road or from the passenger seat while driving. No fiddling around with jets, emulsion tubes and choke sizes - the results are instant.
If you change a componant eg. camshafts, then you can adjust the fuelling and ignition timing to suit without having to buy any more bits.
Most of these systems have inbuilt traction control and launch control to play with when you have found your optimum set-up.
I have done this on 3 of my cars over the years and wouldn't go back to carbs now.
Food for thought?
