Depends on what track you plan to go to. If it's a drag strip, that will be a competative car. If your planning to road race or autoX, you might consider an LS/VTEC or just a B18C1. The reduced weight on the front end will help with overall balance and any reduction in weight is desireable in a race car. Assuming you did mean road racing or autocross, you'll also be limited by the rules of your class as well. Seeya.
