Drag radials at all four corners. Nice.

I understand why the E30 has a left drop... the engine tilts to the right and BMW could package the diff more compactly by slipping it under the engine's left pan rail.

Why the @#$% did Nissan put the drop on the right when the Skyline is designed to be a RHD car? The driver's weight already offsets the car's weight dist to the right.

Yeah kinda strange, but maybe better room for exhaust?

Love this thread..

Is that a Volvo 122?

Yes thats right, but they called it Volvo Amazon in Sweden :)

It uses Skyline front diff, with pretty custom mounting "on top" of the oil pan :)
I have more pics if anyone wants to see.

Not sure, i will try to dig some more info!

Was pretty sure it was a Skyline setup because of the right hand drop. What's he using for a front diff? The diff case is cast into the oil pan on the Skylines.

[Nisse Järnet]

Its a Nissan Skyline gearbox and front diff :) Its going in a Volvo Amazon of all cars :D

race car.

what the flock is that? xfer case on the passenger side? turbo flange that would put the blower inside the firewall? interesting bell housing solution.

Ok thanks, great info! I will use a lsd in the rear so hopefully the trigger wheel will work :)

Btw, someone might want to see this crazy pic hehe:

AFAIK, yes. I just told the guy who was installing the 3.64 gears to ship it back with an E36 rear cover.

The only fun part was that the E30 VSS trigger wheel is too big for the E36 case, but the E36 trigger wheel won't fit the viscous diff, so I had to modify the viscous diff's trigger wheel to work.

The same thing happened with the 210 unit... the E23 wheel didn't fit under the E32/E34 cover. Fortunately for that setup, I just had to swap wheels.

[Nisse Järnet]

Cool, thanks! The E36 188 cover is that from a standard 325i or similar?

Shots of the 188mm E30 case with E36 rear cover and the 210mm E23 case with E32/E34 cover and E36 bracket:









As far as mounts and driveshaft go, these two are bolt-in swaps.

The 188mm has the viscous LSD, which limits it to the 86mm CV joints, while the 210mm has output flanges for 94mm CV joints and can accept the later flanges for 102mm joints.
When the mounts line up, the 210mm positions the output flange centerline slightly rearward of where it is with the 188mm unit. However, this is not a significant distance and will not be a problem for CV joints to compensate.

Ok. I thought the E28 M5 was the only E28 that received the 210 diff. It has 3.91 gears (I thought)... so I was a little perplexed.

I have an E23 2.93 210mm unit with the same case... It'll get 3.64 gears for my swap. I have the E32/E34 rear cover and VSS trigger wheel and the E36 M3 CSL diff mounting bracket to install it in an E30.

I think even the regular E28 535 got the 210 diff as well :)
Cool how does that rear cover look?
