Welded up the sump but it distorted to much so I made up another one without the extra extension at the back.

Made a new pick up, still need to make a bracket back to the girdle and modified the windage tray.

Had the ETS-pro from Full Race turn up, finding this unit was the trigger for starting the whole project.

Few more things done, rebuilt the clutches in the diff. The bearings and back lash was fine so brought the nismo 3843S-R521 kit but should have brought the 3843S-R520 kit.

The R521 kit came with 4 spring plates, 2 spring discs 4 friction discs and 2 friction plates, this made about 130ft/lb brake away.

I used 2 spring plates, 2 spring discs, 4 friction plates and 4 friction discs, this would be the same as the R520 kit.

The brake away torque to start with was 25 ft/lb and ended up with 69 ft/lb. Gave the pressure rings and the casing a polish with some fine sand paper and filed the

sharp edges, this helped the pressure ring slide smoothly.

Polishing the casing where the ears run.

Made some plates to bolt to the flanges for testing and removing the stubs.

Put back together with a quick coat of paint.

Also started to de-burred the block and modified a corner on the fuel tank to give the exhaust more clearance.

Just to confirm, this is an r33 GTR r200?

I've been looking for the part number for the nismo rebuild/upgrade for my r32 GTR.

Who did you source the diff parts from?

Cheers

Justin

Hi Justin yes this is out of GTR R33, I would go the 3843S-RS520 kit

This should help for the part numbers. http://www.nismo.co.jp/en/products/competition/lsd/pdf/repair04.pdf

I brought the kit form rhd japan http://www.rhdjapan.com/nismo-r200-mechanical-lsd-disc-kit-rs521.html

Negun also have rebuild kits. http://www.nengun.com/nismo/lsd-repair-parts

    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
