How Much Can The Diff Take

I was wondering wheather the R32 GTS-4 would have the same rear diff as the R32 GTS-t's. reason being that i have a switch to go to 4WD or RWD. Because of the torque split i thought that nissan may have put in 2 diff's that are half the strength of the 1 GTS-t rear diff as the force is distributed and to save on overall car weight. If this is the case then having the switch to RWD could potentially be doing damage to the rear diff as it is taking the full force. does anyone know?

R32 GTS4 uses the same design/strength R200 diff as R32 GTS-t and GTR (not to mention R33 GTS-t and GTR, R34 etc - there are different ratio's used, of course). There is no problem with strength as long as the diff is in good condition.

under the bonnet, has 4wd or attessa or something on the fuse lid cover to clue you into which one it is. Prolonged use with the fuse out can cause damage to 4wd system(i have heard) if you were to go drifting or something like that. It may be benifitial to raise the car and pull the front drive shaft, about a 5-10min job, 8 bolts in total (from memory)

You don't appear to know how the 4wd works. Rear diff has to be "full strength", so to speak, as the car only engages the front wheels when slip is detected. And I do believe that when the wheels start to spin, there is less load on the diff (less "torque resistance").

Also, in the r32, there is no need to play with driveshafts, as the centre diff has no contact unless activated (unlike r33 and r34).

The fuse under the bonnet is clearly marked.

And I should have my r32 gts4 on the road by next week.

Don't forget to put the fuse back after every run. Enjoy...

Check the FAQ FORUM and click the r32 rwd link. Then rather than pulling the fuse, you can wire up a switch.

Nice one, that was one of my questions answetred too, now could someone please tell me which fuse i need to pull to go rwd, is it the one under the dash, or under the hood? cheers

i know that there is a fuse under the bonnet for the 4WD. its marked on the case : ANTI/4WD/PTC. im not sure if anyone else has hooked up their switch to this but i have ran it through the switch under my dash. i tried to simply pull that switch under bonnet but the car wouldnt start when i did that. ive included pics as to what i have done.and also a picture that is quite possibly the greatest drawing since mona lisa. its literally as simple as my sh1tty diagram and it works perfectly.

P.S. any positive feedback on the drawing is appreciated. hehe.

leads to switch under steering wheel.

you can also similarly turn ABS on and off (great for track).

      This sounds like a perfect excuse to install a Haltech R3.

      I do believe from context he is talking about a S0/S1 R33 RB25 with associated ECU and Wiring for that, and a manual gearbox into a R34 N/A Auto. I don't have the knowledge of all the pinouts and such but my gut feeling from doing my own conversion is to use as much of the R33 stuff that you can. The "car" wiring is quite seperate from the "Engine" wiring when all things are considered. The only things to truly consider 99% of the time is the cluster, reverse lights and potentially disabling the 'not in P/N' immobilizer circuit.

      Rusty roof repair

      A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway.

      Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).

      I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as
