There is alot of things you can do,but the CAI(cold air intake) is one of the cheaper and easy ways to get more power.Also larger throttle body 62mm.Then you have a high flow cat back exhaust.If you really want to get into a turbo or super charger.More aggressive cam,better lifters.Also what tires are you running.I had the same problem running 31" tires CIA fixed my problem cost me $65.00 shipped to my door on e bay.

Before the CAI (I stayed away from it and went with the snorkel instead) I would do the e-fan conversion, mustang injectors and PD ignition... Actually, I DID do that myself.

change the gears to a lower set. 4:10's

4 banger manual transmission should have 4:10 from the factory

If you will change gears, go to 4.88; 4.56 is just not enough to merit the cost...

If you wnat a good site, I strongly recommend www.4bangerjp.com; there you will find only 4 banger owners and between all of them, basically anything that can be done to a 4-banger has already been tried, so someone can give you ideas or tips about what you intend to do...
