I could just use nitrous but this motor has run so flawless I don't need it. 20,000miles and 154 1/4 mile runs and it feels stronger than the day I got it.. jim
jim I'm not sure what the rear swap will cost you but it will drastically change the way the car handles on both the track and the street. going from a live axle to a fixed may not be the best choice. if your bored search undercover performance. the tuner is a master at what he does with the proefi engine management system. launch control traction control are just the tip of the iceberg that may get you were you want to be. its like using a macbook pro vs a commodore 64!
