This transmission will bolt right up to any 1ZZ or 2ZZ engine in any manual transmission 2000-05 Toyota MR2 Spyder. No adapters, other parts or or custom work of any kind are required for the installation. Works with stock or aftermarket clutches, flywheels, shifters, shifter cables, axles. Includes shifter shaft and reverse blockout; does not include external mechanism pictured (reuse the one from your old transmission)
Axle ratio is 4.529:1 (same as stock Celica and Lotus), so it is the best choice for NA performance and for road racing applications where short, tightly spaced gearing is needed. You will see a performance and fuel economy improvement compared to the stock 5-speed.
MWR recommends a maximum of 275whp for road course use and 350whp for street use though actual transmission durability will vary based on usage, vehicle weight, torque, clutch type and heat. If you will be exceeding those numbers you should definitely consider stronger solutions such as Jubu or Kaaz gear upgrades or MWR E153 swap for high power street or road course.
