I'll have to dig up some old SCCs and find out what other 240sx's competed, and why they lost. It would be fairly straight forward to build a competitive car, but keeping it in one piece would be the hard part.

I'd say that TR's best bet would be to have Enjuku build it. They have the engineering talent, drivers, connections, and lots of experience with parts reliability. Plus, the red tires would pwn in the gross display of HP competition!
