Can anyone please suggest me whats the best way to go and how much would it cost and all or is it worth doing it..?
Well even tho this is a WK forum (you have a WK2), here is some pointers. from one 3.7 owner to a 3.6 owner:
1: make her breathe better. a good catback and intake will help make the engine more efficient. efficiency produces power.
2: look into a fastman ported throttle body to further help get air in
3: i'd say headers, but im not sure they are made yet...
4: do some research into different tuners that may be on the market...Hypertec may be your best bet
5: keep up on your maintenance and she will last
