The twin turbo Supra engine is a beauty, gobs of power with refinement. I drove one with TRD parts which was making close to 400bhp, that thing was a monster and yet the engine remained so smooth even close to its rev limits. You simply couldn't destroy it. The original I6 engine in Supra was designed in conjunction with Yamaha and remains as the all time great engines in the automotive world along with others. The V6 Yamaha designed SHO engine for Taurus comes to mind.
