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.

yeah, I've got the switch in my GTS4 as well...

wire coming out of fuse box...

leads to switch under steering wheel.

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

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
