Limited slip differential options - Toyota Yaris Forums

There's a few options for Quaife, based on which gearbox/engine you have:
1.5 L 1NZ-FE > QDF15E
1.8 L 2ZR-FE > QDF21E

Both of these units are 8-bolt, but the 21E uses the larger output shafts of the 1.8 L model, and has a different shoulder diameter for the front ring gear. If you have a 1.5 L, you need the 15E.

I guess that means one needs to be careful getting a used helical from JDM or EU. Good info. Thanks.
