There's actually a quicker (and cheaper) way to do it than Mtld's way.

What I did was took the Nissan 240 SX and set it to Drag mode (when in the Garage, press X to change modes). Once that's done, buy a level 2 engine (boosts HP by 27) and then update blueprint, and you'll have your level 3 vehicle as well (Performance Upgrade achievement)
