An excellent book published by CARTECH and written by Sean Hyland, titled: How To Build Max-Performance 4.6 Liter Ford Engines, is an excellent resource for anyone contemplating rebuilding or modifying a modern four valve (or five valve) V8 such as the Audi.

Many topics are discussed, at length, in the bbok including fuel injector sizing. Check it out!

as long as it doesn't tell u how to wire a cruse control unit, I'll check it out ;)
