vw 1500 engine tweeks

a well tuned 1500 is a potent motor without tweks but a good set of extractors will always make things better and a set of twin carby's would do me
good luck

bore increase to 1640cc, Twin port heads, extractors and some Kadrons (twin carbs)......thats probably the easiest and cheapest upgrade outside of a full rebuild.

Dont want to steal this thread but i already have a 1600 twin port, would i gain a lot more horsepower by just adding extractors and twin carbys?

^yep.
