Belt lengths for MWR 1ZZ and 2ZZ Supercharger kit with vehicle variations. Click the one you need to go to product page.
Where “underdrive pulleys” is noted, it is the measurement for both MWR underdrive alternator and water pump pulleys installed. If you have only one of the pulleys installed you’ll have to take your best guess at length.
If you have a Celica/Corolla/Matrix/Vibe with power steering removed and MR2 style idler pulley installed in its place please order belt specified for MR2.
If you have a Celica/Corolla/Matrix/Vibe that started out as a 1ZZ vehicle (2ZZ swapped now) and you’re still using the 1ZZ power steering pump you will need a belt 1″ shorter than the one recommended for the originally 2ZZ version of your vehicle.
