It recommended 38420-RSS15-C5 for S14 SR20DET MT, install instructions mention C5 kit has 38220-0V161 (Qty2) side flanges ie same, whereas D5 has 38220-RSS50 & 38220-4P071 side flanges, ie different ones for driver/passenger sides. I found as Bling above, I needed asymmetric flanges.

Pulled diff out of my s13, snapped a tooth of pinion. Now it's an abs, 4.08 (viscous) with 6 3x2 bolt shafts (thought was r200 but not sure now)
With the small front mounting bolts and 4 bolt rear casing,,
I bought a 4.11 r200 abs 5 bolt shaft diff out of r33
(Large front mounting points with bushings, and 2 bolt back casing)
Now the plan was to transfer pinion and centre over to my casing and fit.. Done a dummy fit and its appearing like not going to work well, without some light machine for clearance..
So what I'm trying to find out now is ( as if rather not do any machining etc) if I swap the rear casing over, and aquire some longer bolts and bushings for the 33 diff... Can I bolt that diff/casing into my s13, will that work? ( before I got transferring the centre and pinion back into it)
Also yes my shafts appear to fit into the new centre fine too, so doesn't appear to be an issue there.

Long story short ive built an R32 GTS rally car. Its using the GTST brakes and hubs and currently has a 4.3 open ratio diff which i believe is from a 180sx as its an R180 with the small ears, 4 bolt rear cover and 3x2 bolt flanges. Firewall code suggests its meant to have a 4.1? If i recall correctly.
Anyways, im planning on keeping the engine the RB20DE, so i cant use the extra HP of a turbo setup to benefit the launches and out of corner speed requirements im having. But what i want to do is fit a taller ratio diff. Something ideally around 4.9 or even 5.1.
I need it to have LSD also. Welding it will not suffice.
Is there any suggestions for what to look out for to fit my requirements? There is so much misinformation out there its becoming harder to precisely work out whats the best combination of parts.
I was hoping to find the unicorn front r200 diff fitted in some navaras/pathfinders that ran the 5.1 ratio and pinch the parts to use in a vlsd r200 rear diff and use the 5x1 shafts and half shafts if needed. But not having much luck locating anything as yet. Ideally a clutch packed LSD would be best but im happy to shim the vlsd to accomodate what i need. Also plan to swap the rb20 gearbox to a z32 gearbox to assist a tiny bit in the wide gap between 2nd and 3rd. Affectively tightening that up a fraction. As down the straights, Its a sleeper.
Very much appreciate any of your idead and assistance.
