Andreas, if you can supply me simple drawing from VLSD ring gear, we can go forward.

I have an Autech RS5F32V box and when I rebuilt the VE purchased a Nismo LSD. I was only able to get the one for the A series box as the VLSD ones had sold out & Nismo no longer made a mechanical for the V box.

I thought all I would need to do is buy an open box to fit the Nismo into & then it would be a simple matter of just popping the Autech 4.3ish gearset in for a nice gearbox with a mechanical LSD in it. I went out & purchased a JDM RS5F32A 3.8 gearbox to do this.

The VLSD gearset wouldn't swap into the A case & vice-versa... one was too tight & the other too loose, I've also heard of others having the same problem. I ended up buying a third gearbox with the 4.1 gearset & having the Nismo fitted to that. I may have done something wrong but a couple of us looked at it & couldn't make it work.

The Autech VLSD now resides in my other car & the 3.8 open box lives on the garage floor. If I'd known that was going to happen I would've spent a bit extra on a Cusco LSD for the VLSD case as the Autech is far better suited to the VE & makes it easy to keep on-cam.

yeah, the A and V diffs and casings are different, not interchangable.
I agree, I much prefer the VZR gearbox over the std 32A, and its not really detrimental to 1/4 mile racing for me, rather extend the limiter to 9000rpm to run if over the line in 3rd.

going to go for the Cusco LSD myself I think

For Highway purposes the b15 trans looks great.


My sr16 has a hydraulic set-up?

FYI, in Europe we have 98% of RS5F32A boxes with 4,1 FD.
And from 85kw Primera W10 (P10 Primera Estate) we can also get 4,35 FD, but it is hard to find.
I have one 4.35 for RS5F32A from W10 somewhere in may garage...
