20 How can I get more power out my VW?

A:Buy a VW a VR6 engine :-. It’s an FAQ that’s

of a book, and that’s probably you should start.

After you go this FAQ to give you some

idea, look at the info under power upgrades:

improvement. VWs have much less for easy

improvements because of the components are already


One easy upgrade path for VWs is therefore to look at

newer VW models, see what they and see if you

can swap parts. For example, VWs have the restrictive

exhaust swapping it with a large one from
