Well I am sorry but I work at Sound Performance (big supra shop in midwest) and the mkIII trannies will hold about 600 horse as long as you don't speed shift and not a race clutch and pressure plate, and the 6-speed's can hold over 1200 with speed shifting as seen with titan motorsports. But to say how long with constant abuse is a tossup. If anyone has questions about the transmissions or anything else about supra's let me know. and the clutches are hydrolic.
