2018 Diff swap
 

Hi, everyone, we have a 2014 86 with the "basic basic option" used by TMG to develop their race version for europe

It's a 3.7 gear ratio and open diff.
We would like to upgrade to a torsen and a shorter gear ratio, and I found this diff here for a very good price.

It's from a 2018 Auto version, so the ratio is 4.1 instead of 4.3 (that would have been better) but this won't bother us too much.

is there a way to confirm if this is what we are looking for (torsen and 4.1 ratio) and will it be bolt-on on our 86? thank you so much for your support

I believe that is the diff you are looking for. The 4.1 w/torsen that came out of my car was also a Y38.

Picture in this post when I sold it.

Thanks! Is it an easy swap on a MT?

It is not very difficult. I had the car on jack stands and used a floor jack to support the diff during removal/assembly.

Great. I just wanted to make sure it's bolt on

Just be sure to inspect the new diff before install. Check that the two bushings are in good shape and that the seals for the CV axle look okay. I replaced the seals on mine before install just to be sure, though I probably didn't need to.

Got it, thanks! will install it and give you a feedback

thank you so much
