370z differential swap
Hey guys I'm looking to swap a 370z VLSD 3.69 FD pumpkin into my base 350z and I found a few on eBay that say they are LSD, but don't say the FD ratio. So I was wondering if all 370z LSD are 3.69 or the auto 370z have a different FD like the 350zs do? I tried googling couldn't find a definite answer. I don't want to buy a 3.3 FD so I'm just trying to find out if even auto VLSD are 3.69 FD.

The Z34 (370Z) pumpkin swap into a Z33(350Z) works without any modifications....as long as you use a Z34 complete rear diff pumpkin assembly from a manual transmission Z34, and install it into a manual transmission Z33. We are running a 3.69 pumpkin out of a 2016 Z34 Nismo in our 2004 Z33 Nismo and it bolts right up. We opened up the diff and removed the OEM VLSD, then installed a Nismo 1.5way LSD given we are endurance racing. The 3.69 gear ratio was the exact gearing we needed for our home track.
