UPDATE: XAT Racing has closed down.
They also offer complete package swaps including the car such as a 240SX with LS1/T56 for $13,500. Check out their for sale area for other cars. What if you just want an engine and transmission? Well they sell engines alone if you feel like taking the swap on yourself.
They sponsor 3 Pro Drift Racers with the most recent win coming from Rob Fleming in the NOPI Drift Championship in Miami. If you need a swap done and are near Tampa these guys seem to be able to get the job done.
