I currently have an R32 gts that has had an RB20det put in it. The gearbox is also RB20DET. but the diff feels like a single spinner it will allways spin the inside rear wheel and when jacked up the wheels spin in opposite directions confirming it in not an LSD.

I have had a look at it and it has 6 bolt half shafts. (3 x 2) bolts. it also has a 4 bolt finned rear cover is it a GTS diff or has it already been converted to GTST?

Are R32GTST diffs 6 bolt half shafts or five?

I think a factory lsd in good nick will be good enough for my needs, so I need to know what sort of diff will bolt up.

I would prefer doing this to taking the centre out and putting a new centre in my housing as I will be putting it in myself and I dont have good or big enough sockets to go pulling crown wheels off.

Can someone list what sort of diffs will fit? Will a GTR mechanical diff fit?

Thanks!

From what I gather...

you can replace the diff centre (shortnose R200... whatever that means).

this won't change the ratio, and is what I would reccomend. Except get an aftermarket mech 1.5 way...

I THINK that you could swap in/out a whole diff. (but I'm not sure... and the rear driveshafts might be different).

second hand lsd's (stock r32 gtst or gtr) will be a bit of a gamble. I recommend something aftermarket such as a Cusco/Kaaz/Nismo 1.5way etc.etc.

You also need to confirm that you have an R200 housing, and it's not an R180 housing. I'm not sure if any of the skylines came with R180's across the range of non-turbo r32's but it's something you need to check, non-turbo s13's came with r180 housings, and the r200 housings and driveshafts bolt straight in.

if it's an R200 housing, an R200 diff centre will fit, but you may also want to check that you're happy with the ratio.

I recommend taking diff's to a diff place to get centres fitted if you don't know what you're doing, because there are shims and washers and crap that align the diff centre with the pinion/crownwheel. A friend once stuffed the alignment up on an Rx7 diff and the diff crapped itself after a week or two....

Will do,

I have spoken to sss automotive and they have a R200 with 3x2 half shafts that will bolt into my car but at this stage they do not know wether it is a 1, 1.5, or 2 way or what brand it is.

they want $700 for it. I might get them to find out exactly what's in it and if it's a 1.5 way kaaz/nismo I will take it :D

or does $700 sound too much for a 2nd hand diff.

      Just be warned that that turbo will not be a direct re-fit to the car. The exhaust housing is, of course, in the same place. It has to be - it's bolted to the exhaust manifold. So the dump will fit up. But the centre housing is not as long, so the comp housing will move backwards. This will affect both the turbo inlet and the outlet. There is fab work that needs to be done. Yes. it has one, it should have one. Paper gasket.

      I only recently purchased the vehicle, it came with the flex setup but the current tune is e85 only, which is why im wanting to get the tune redone to enable a mixture.  First i need to get the exhaust redone tho. I was thinking of getting a varex muffler but it sems they dont fit well in the 33 (hang low because of the valve mechanism which sticks out on top) and generally dont sound good. So that leaves me with redoing the entire exhaust (more resonators and mufflers) so its not a menace when i come and go from home, and then have the aes dump valve somewhere along the line to really open it up. I was thinking of having it before the cat but after seeing how insanely loud it will be (on a vl turbo) im thinking of putting it more towards the rear of the car, after one of the resonators.

      At this point I'm just 'hoping' it's the turbo seals. I did speak to someone who said it's normal for these turbos to have a bit of axial play? Not gonna lie I've never checked a turbo for axial play before but you could hear it tapping a bit as I moved it back and forth. Surely that's too much? My theory is (could be completely wrong), bad axial play, worn bearings, bad seals, oil into dump/compressor side, burns in exhaust = blue smoke. On a timing belt related note, my crank pulley was missing that front plate that sits in front of the timing belt. It's that metal round plate. It did have the rear one, and the woodruff keys are in the crank which was nice. Can anyone confirm if the NEO det engine has a front plate, im sure it would to protect the front of the timing belt or something. Water pumps...the pump I got was an NPW (yes grill me if I should've got a genuine one lol). It has a smooth mating surface, kit came with a pretty pathetic looking paper gasket. Do I need to use any RTV or just trust the gasket will work because its a smooth mating surface? Cheers legends have a good Easter break!

      Cheers man, I thought the same.   Bit of an update on it all. It was definitely blue smoke, not grey after all. It didn't really smell oily but it was blue after all. Also puffing just the smallest amount on idle with no throttle.   I ended up pulling the intake and exhaust off and there was around 3mm of axial play on the turbo shaft. So I figured we'll that's buggered and sent it off to get hi-flowed at hypergear. Haven't got it back yet.   I haven't compression tested it yet. Had a look in the cylinder and cylinder 1 spark plug, looked a bit sooty but not oily. Then I've just started doing my timing belt because it's age is unknown.
