Thread: LSD for RS5F70A gearbox

I currently have a RS5F70A gearbox which I plan to fit to my build N16/B15 with QG18DE (expected ~300hp) and am looking for a LSD. Understand Nismo no longer produces the LSD and I have tried contacted Quaife, ATS and Carbonetic but all of them responded saying they do not have an LSD application for my gearbox. Cusco did not even respond to my emails. What are my options beyond a Phantom Grip?

You need the entire gearbox for the SR which has the LSD. The back case is different to clear the larger diff.

Get the SR RS5 trans and do a bell housing swap.

Thanks for your input.

I've been trying to arrange something like this with Greg V (GSpec) but apparently shipping to where I am (Malaysia) is very expensive

Wonder if anyone has a used Nismo LSD for the 70A gearbox for sale?
