You will need sticky tires. I am sure that motor has a 12 second pass in it with good traction.

I get no traction at all. If I'm rolling at 20-25 MPH and drop the hammer, the tires will actually smoke. Off the line is silly, they just spin. I plan on getting some traction/lift bars, springs, shocks, and some fatter tires.

Funny you should mention that. I will be ordering headers, torque converter, and the suspension components I mentioned above next month.
My delema is wheels. I'm torn between leaving the stock wheels for street driving (would make a good sleeper) and getting some cheep rears for the track or buying a nice full set of custom wheels for all four. Here is a picture of the car.
