Stick with the 19LB injectors in the car. A bigger injector will kill it unless you are going to supercharge, NOS, or do a heads, cam, intake. Plus you would have to get a mass air meter calibrated for the bigger injectors.

Yes, I would recommend the BBK shortys headers and off road H pipe. Like I said You can get an upper and lover intake off an V8 explorer. These intakes flow #s are almost identical to the GT40 intake (Came on the 93 Cobras) And they can be had for around $50. to $100. They are a direct bolt on and look similar to stock.

The heads off the explores are GT40s too.

With a little work and some wise parts shopping you can really wake this car up
