A search didn't give me what i wanted to know so i'll ask :P.

I'm looking for a decent diff for my S13, mechanical 1.5 or 2 way is preferred of course. Now i've come accross an R32 GTR diff, axles and rear hubs. This would seem perfect since i want to go 5 stud at the rear anyways so i want some info on the parts.

Is the R32 GTR diff a clutch pack type and how many 'ways' is it?

Are the half shafts unique to an R32 GTR (ie if i snap one will i have to replace with a GTR part because of unique spline count etc)?

Will it bolt up to a Silvia after swapping the rear covers (looks like it will)?

What is the diff ratio?

Im not an expert, so someone will correct me. I beleive they are a hlsd. There is no "way" in which they operate, but its similar to a 1 way. There are no clutches in it, only gears.

Ususally you do need the half shaft it came with, dont worry as they are strong (ever heard of a gtr snapping one?)

If you put the centre in your housing, with the halfshafts, and axles, you can retain the ratio you have now...(which is the other option i was looking at for my car -s13 ratio with gtr running gear)

i think there were a few different diffs that came standard / options with r32 gtr's

I remember reading some people had mechanical lsd's stock, and some were viscous.

What is the price of that diff you've found? kaaz 1.5 or 2ways can be had for around $1,100 or a second hand one for $600 or so.

contact, www.garage-13.com I know alex has a couple of second hand mechanical diffs lying around for a very good price

They also specialise in 5-stud conversions for s13's, so they can let you know what you'll need.

Ah k, a helical or viscous isn't of much interest to me, i'll see if i can get a photo of the centre, it'll be easy to tell then.

Did they ever come with a clutch pack centre? Being a hipo car i thought they might have gotten a clutch pack in em.

- All r32 GTR LSD's are clutch pack to my knowledge. It's possible there may have been other centres used, but FAST indicates they were all clutch type. Not sure about the 'way' thing, my interpretation of the design of the stock centre is it's 2-way.

- I believe the bolt spacing might make them 'unique' but I've found halfshafts are interchangable between R200's (believe it or not S15 halfshafts fit 260Z R200...and vice versa). The exception is viscous LSD's which have a unique design.

- rear cover should swap over no problem, but also consider whether the tailshaft attachment is the same (should change over anyay).

- 4.1

Cool, the number of 'ways' of the diff is pretty easy to tell by eye (from the angle of hte 'ramps' that actuate the clutches), i'll work on getting a photo of the guts of the thing. Since it comes with Shafts and hubs i guess thats not really a problem and the tailshaft flange is most likely the same but can be swapped with my current viscous diff if need be.

Thanks :P

no GTRs come with a viscous diff, they are all a mechanical LSD. 2 way.

Thats ok, my last drifter had a stock long nose clutch pack LSD that was loose to, i found it quite fine to drift with since i was applying enough torque to lock it up nicely :P.

EDIT: i bought it now, we'll see how it goes :P.

      I just got to work and skimmed through 61508 and 61511. I was surprised the CSA adopted both, but neither are enforced. To recap what I read, it states that in a perfect world, they should be segregated but they acknowledge that this is not industry standard and clearly mention that they allow mixing of safety and non-safety. 61511 also mentions software segregation like AB does in their safety PLC's.   Now if only I could go back to control, let alone safety over comms. In my current line of work, we're only allowed monitoring and basic control over comms. Everything critical must still be hard wired as much as possible.

      I've unfortunately never been as they're on the complete other side of the continent and another country that isn't currently letting us in as easily as they use to. I even heard their stop signs over there actually say "Stop" instead of "Arret". If I decided to trek the 48h drive, I wouldn't know when or where to stop haha. Whenever I order parts from UP Garage, I order from Japan as it's cheaper. Same with GKTech... oddly enough, it's cheaper shipped from Australia then it is the US.  UP Garage Japan operates their US leg though, unlike Tomei. If Tomei JPN had the power to close down Tomei USA, I'm sure it would be done in a day. They're two completely separate entities. Tomei JPN messed up somewhere originally agreeing to its creation and got sacked big time.

      I asked someone about this and he told me about the Audi 1.8T engine. But I think it would be difficult to swap

      I don't know that machine specifically, but I'd personally go for something with a little more kick than 130amp. Around up to 180 would be good. At the 6mm range, you're really pushing the machine hard and don't have a long period you can run for with out needing to give it a rest. Lots of MIG machines come with a regulator and hose. A lot will come with a starter roll of wire too, but it isn't too expensive to buy. I'd recommend NOT buying a massive roll too, as you don't want it sitting around FOREVER in the machine between uses and potentially going to shit. For thin sheet metal, get a roll of 0.6mm if you're doing over 3mm and above, switch over to 0.8mm wire. Even by 2mm you'd probably really want to switch. As for gas battle, it's all swap and go style now. You'll pay a bottle deposit, and then X amount to swap for a full one. I think it's like $200 or $300 for a D Size bottle upfront as "deposit", and like $110 to $150 per swap. My D size CO2/argon bottle lasts a fair bit of welding on the MIG. And I run an E size bottle on the TIG. For DIY MIG, stick with a D size bottle. If you really start to get into a LOT of welding and doing it really regularly, then upgrade. If you're like most DIY car guys, one D bottle will last you 2 or 3 years easily. I think I've been on my current bottle about 5 years. It is starting to get low, but I've been smashing it a lot more the last 6 months.

      SR20s came with cars like the Bluebird and Primera, but the RB20 never came. The ones in Turkey were either brought in specially or from abroad. That's why RBs aren't as common as SRs. And if a part breaks or I need to replace it when doing maintenance, it's harder to find parts for RBs.
