can you get mini spools for the stock MR30 diffs and on another note do you need a different drive shaft to run a r200 longnose in an MR

I advise strongly against lockers in an R30...mate of mine had one for a bit and he broke half shafts like you wouldn't beleive, killed couple of diffs, and at one stage we broke a half shaft which cut a rear brake line as well....yuck!!! Don't do it

I know some people that locked the rear end of their MR30 and they don't have any problems with it. It should be fine provided your cv's aren't up the shitter.

For your money I'm told a locker is the best bang for your buck.

couple sidenotes;

Replace the bushes allround with poly-uraphane ones.

Don't let off the throttle in the middle of slides, you'll just spinout.

When driving, you're either sideways and it's on, or you're not and it's off.

of course, if you're allot less inclined to go sideways then buying an LSD probably isn't worth it in the first place.

locker = cheaper, especially for track drifting.

Gostrider: You said before that nissan have never made a R220(9 inch) but they actuly have! But its a shortnose type and they come in Z32 300ZX's!

And what are all you guys going on bout lock diffs being bad or what ever? They are perfectly safe in R30s they dont break axles at all I have had the same one in my last 3 HR30s(built it for my paddock/derby car) and then it went into my turbo roadcar then into last non turbo roadcar and it was with the same axles for all of them and it probably ended up doing around 10000kms or more so far! and a mate has had a locker in his C31 laurel for the last year and a half and has not broken anything!

Stuff having a R200 LSD unless they are rebuilt with a higher pound kit as they are just to inconsistant and unpredictable and so over priced its just stupid!

Maybe you should read more posts as you will see I said the factory R200 mechanical LSD's are no better than a single spinner (open diff) because Nissan used them as a marketing tool more than a performance option.

I have 2 x R200 LSD's, both long nose, both 2 way mechanical, one is a Cusco centre with pre loads of about 80lb and the other is the stock Nissan out of my PNV.

As for Nissan making an R220, your full of yourself, the Z32 and S13/14 and R32/33 diffs are all R200, no such animal bigger in IRS made by Nissan.

I have one, short nose viscous LSD 3.692:1 from a manual R32 and it's most suitable as a boat anchor.

I thought the Z32 300ZX-TT diff was the R230... http://www.google.com.au/search?hl=en&...+r230&meta=

Phil,

I looked at the link, but I don't know for sure how they categorise the Z32 diff, but what I can tell you is, the R200 back plates are interchangeable. From our long nose mechanical DR/HR30's, HR31's, Z32's, S13/14's etc. They are all interchangeable, the later ones just have allowance for the ABS.

I have this back plate on my R200 long nose.

By Quaife do you mean a Torson gear/worm type mechanical LSD ? Very interested to see details if thats the case .

Cheers A .

Yeah that's the one, Quaife from the UK make it, they call it an ATB (automatic torque biasing) diff, so similar to torsen.

I got it through Palmside http://www.palmside.co.nz/ in NZ, he (Deane) ordered it in and then posted it to me in Newcastle, very easy.

I had a diff shop fit it, they had to bugger around a bit with shims setting the backlash, but all went together good.

So far I have taken it around Wakefield park, and it seemed great, great traction and very smooth. Going in a hillclimb this weekend so will see how it goes around tight twisty stuff.

I put a KAAZ LSD into my R200 Longnose. It is a real cranky bugger when it is cold! No difference between it and the locker it replaced (except when the clutch pedal is down, of course).

Disco, here's some details on the Quaife ATB for your R200.

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
