I was watching the drifting going on at Eastern creek last night , and i saw a r33 skyline non turbo drifting he did have alot of trouble with his single spinner, but towards the end he got alot better, he also stock suspension by the looks of it.

I was thinking about throwing on some coil overs and a turbo r33 lsd heard the gear ratios were the same.

Anyone ever installed the GTST LSD on a n/a? does it handle alot better?

The ratios are different, the GTST diff has a longer ratio.

Also the stock diff if a viscous diff which pretty much all of them are worn out and will just single peg all day long. you could shim it to lock it a bit more. there is a thread in the DIY section about it people have had good results

What car are you planning to do this with?

If you have a 33 ratios are the same for NA or turbo but it depends on if you get an auto or manual diff.

If you're planning it for a 31 which is the only car you have listed then it's a lot more involved.

If Jap Spec IRS They run an R200 Longnose diff which isn't just a simple swap. You'd probably need to do the whole subframe etc with custom mounts, custom tailshaft etc.

If Aus spec live axle you will need to do the same as the Aus specs run a Borg Warner diff which is entirely different. Kaaz offer an LSD centre for these diffs or you could use a cone type LSD out of a Sillhouette though I don't think they are particularly strong.

Haha i just edited that part of my profile as you were posting, Yeah i have a r33 non turbo. i think the auto diffs have a 4.3 something ratio, which is higher then the manual ones.

Yep autos are 4:3, manuals 4:1

If your car already has an LSD shimming it is your cheapest option. If it's a single spinner then you'll need to source an LSD centre and probably shim it.

If you post your VIN in the VINS you want fasted thread in General automotive discussion it'll tell you if your car is a GTS25/S which will have an LSD or just a normal natro which won't.

I also have a R33 S1 and well looks like there are a few of us that are in the same boat. Now which do you guys think is best? shim or just solid weld the diff? Why do you prefer the weld or the shim? and what prices would one expect to pay to get the diff welded or shimed? I do not know much about a diff except how it operates. Any advice would help

Shimming costs more and retains some form of LSD depending how "tight" you go. Welding it is as simple as well welding the spider gears lol.

Get a mate that's handy with a welder and give him a bottle of spirits (as payment), down side is its illegal and very easy to see/hear on the street.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
