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.

Cheers, D

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.

      Hypergear Turbochargers and High flow Services Development thread

      I know this one’s the BB one. My tuner did make mention about the actuator. I am curious about the VCT as well

      Might also needs a stronger actuator with the right preloading. With older 2019 built bush G3 units, BB upgrade or 21U housing down size makes a pretty decent gain in response as well.

      Need help/advice with bearing taper clearance, eccentricity and arp studs.

      By Desean Strickland · Posted

      Hey lads  so im finally putting together my rb30 forged bottom end and ran into an issue. I measured my main bearing clearance with arp main studs torqued to 60 ft-lbs using ACL H series STD size bearings and standard, un-ground crank shaft journals and got an oil clearance reading of about 1.3 thou measuring straight up and down and about 2.8 thou measuring at a 45 degree angle (just above and below the parting line). My machine shop said they measured the main tunnel and it was all within spec (they didnt say the actual measurement) and to go with a standard size bearing, which i have done and the clearance is too tight, I'm guessing because of the extra clamping force from the arp studs distorting the main tunnel. I was wanting to run about 2.5 thou main bearing clearance.  My questions are: 1. could i just use the HX extra 1 thou clearance ACL bearings? that would fix my straight up and down clearance making it about 2.3 thou, but then would the side to side clearance be too big at around 3.8 thou? 2. what actually is the recommended main bearing clearance for measuring near the parting line / side to side. i know its supposed to be bigger as the bearing has some eccentricity built into it but how much more clearance should there be compared to the straight up and down measurement? at the moment there is about 1.5thou difference, is that acceptable or should it be less? 3. If i took the engine block + girdle back to the machine shop and got them to line bore the main tunnel (like i told them to do the first time, but they said it didnt need it) what bearing size would i buy? the STD size bearing shells already slide in fairly easily with no real resistance, some even falling out if i tip the girdle up-side-down. If im taking material out of the main tunnel would i need a bearing with extra material on the back side to make up for it? this is probably confusing af to read so if something doesn't make sense let me know and ill try explaining in a different way. My machine shop doesn't come back from christmas break until mid January, hence why i'm asking these questions here. TIA for any help or info

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I bought the model back in Japan in Feb. I realised I could never build it, looked around for people who could build it, turns out there's some very skilled people out there that will make copies of 1:1 cars or near enough. I'm not really a photo guy... but people were dragging me in a group chat for the choice of bumper as someone else saw the car before it was finished as they are also a customer of that shop. I took the photo in the above post because I was pretty confident that the lip would work wonders for it. Here's some more in-progress and almost-done pics. It gives a good enough idea as to what the rear looks like!   I have also booked in a track day at the end of January. Lets all hope that is nothing but pure fun and games. If it's not pure fun and games, well, I've already got half an engine spare in the cupboard

      Well, do ya, punk? Seriously though, let's fu<king go! The colour and kit looks amazing on the car. Do you have any shots from the rear? I don't quite follow how the model came around. You bought the white kit and he modified it to match your car? Looks nuts either way!
