I've just had an engine conversion done on my 95' GTS4, but the front diff was left as the original Stagea diff which is a 4.083 ratio, and I've still got the original GTS4 rear diff which is 4.363 ratio. It runs but if you downshift gears or at low rpm has a good shudder to itself.

Can anyone suggest where I could get a 4.083 rear diff, the cars I know with these ratios are Nissan Stagea Auto and also R34 Non Turbo Automatic, S15 Non Turbo, S14 Turbo/Non Turbo Manual or S13 Turbo/Non Turbo Manual.

Pm any advice

Cheers

Dan

DON'T drive your car anymore! You're going to destroy your transfer case with the different ratios like that.

I have a 4.08 diff in my GTS-T that I'm about to take out, but the reason I'm taking it out is because I suspect the crown and pinion aren't marking up properly...has a lapping sort of noise at around 60-70km/h. Won't know what's wrong with it until I pull it out and inspect. But anything is going to be better than the different ratios you're running...PM if interested.

Don't drive your car!

just get the original 4.363 diff out of your old engine and have it fitted to the new engine. that will solve your problems. in the meantime disable AWD (there is a way to do it for R33s) or as above don't drive the car.

Better still get a pair of 4.1 GTR diffs - good way to get a mechanical LSD (in fact just the 4.1 rear diff may be close enough for the attessa).

Pull the front driveshaft AND pull the awd fuse in the meantime

GTST already run a LSD im quite sure, In regards to the diff, Im sure someone into drag racing would like the short gearing of a GTS4 diff so you shoudlent have trouble sellin ga funding another one to match,

There's a big difference between the pox-ridden uselessness of the viscous LSD in the lesser cars and the mechanical LSD in an R32 GTR.

sorry mate, the only skyline with an LSD worth having is the GTR. they might call the GTST diff an LSD but it's just a crap viscous POS. they were average when brand new and time and kms doesn't make them any better. by now they are nearly all single pegging and unpredictable. you ideal want a GTR diff which are mech 2 way LSD from factory and work very well and can be rebuilt for around $300 to be brand new.

I did the same conversion to my R32 GTS4. I got a Stagea rear diff from one of the import wreckers in Sydney - I think it might have been UAS.

Just get the gears transferred to your diff - I think the Stagea rear is non-LSD, so you certainly don't want the centre out of it.

my bad, i ment the GTS4 has a a decent LSD, unless other can prove otherwise?

On reflection, pretty sure it was Just Jap.

    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
    • Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers 
    • The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work.
