I pulled my r32 diff apart to shim it and found it had 2 1.10mm shims standard! Already had 2 1.2mm shims to put in it instead of the rumored 2 0.80mm shims, oh well, put in 2 1.10s and a 1.2 total 3.4mm, way too tight! lol. Pulled it back out and put in a 1.49 and 1.2 total 2.51 couldn't really feel it. Then tried a 1.35 and 1.49 total 2.84 not bad, still slightly lacking lock. Then tried 0.75 0.95 and 1.49 total 3.19 too tight again! It is bloody touchy and hard to get spot on! Seems to be either locked or stock, their might be a 0.3mm window that you can fiddle with to get the desired results.

I've seen another diff with 0.75 and 1.35 in it when pulled apart!?

Not sure if after all they are 0.80mm both sides all the time, other people measured their old shims once their out?

Yeah one of my mates used a battery powered snap on rattle gun for his. I headed up to Beaurepairs and the guy there rattled them off for me for free which was nice :P

Just went for a drive then and definitely a big noticable difference using a 1.2mm shim. Clunking and shuddering like a mofo around tight corners haha :D Seems to hook up pretty well though out of corners under power which is just what I was after.

So yeah, all in all pretty pleased so far, will just have to wait till Thurs to see how it holds up at Wakefield...

hey mate, how did the diff hold up at wakefield? would loke to know

Thanks for the tutorial, it was easy to do with your instructions. Put 1.49mm shims on both sides and it's REALLY tight now, inner wheel jumping in tight corners. Can't wait to test it on the track. Hope it loosens a bit after some driving, that's what I understood from other posts.

By the way, is there a specific place were the breather hose should be? Couldn't find any.

tis a long story haha

you'll be happy to know that swanny180 thoroughly enjoyed the diff at the track as the inside wheel doesnt light up coming out of the tight hairpin.

however a crown wheel bolt dislodged about a week or two later. this broke the diff casing and required an expensive towing of his car! make sure those bolts get done up tight, impact wrench tight.

Hahaha sorry hadnt seen this earlier... But yep thats basically it.

Brilliant traction out of tight corners, its surprisingly noticable.

Diff is quite clunky and tight on the street, but if it is traction you're after it definitely works.

As IntercooL said I made the mistake of not doing up the crownwheel bolts tight enough, so ended up with a nice big hole in the rear cover of the diff where a bolt made its bid for freedom, and about a litre of diff oil spilt through the uni car park... ...woops? ;)

So yeah moral is that its a decent cheap mod for the track, isn't the best for the street (ie girlfriends don't like it much) but is tolerable, and you NEED to make sure the bolts are loctite'd and done up farkin tight.

Hope that helps :D

hey guys i did this mod July 2007 (look at page 2 on this thread), just thought id let you all know how its going. One year and three months later, its still the best mod i have done to my car. my car now has 280rwkw, a roll cage, no rear seats, racing seats and harnesses (taking my drifting pretty serious theses days lol) but still after all the mods the diff is still the best. held up perfectly now for 5 full drift track days plus all the street driving i do as well. hasn't missed a beat. GO the shims!!!!!!

put some loctite on those bolts and do them up tight. put it on all of them including the housing and the bearing caps not just the crown wheel and pinion

I assume from your for sale ad that yours is still going strong Trust33?

i am tossing up whether to go all out and get a kaaz/nismo 1.5 or 2way, put a spool in it or shim it, judging by this thread shimming seems like a cheap effective option.

would adding a shim to a single spinner make it a shimmed diff & make two wheels spin ?

no will only work with an lsd, if your talking about a skyline though, i believe all are lsd in which case shimming should work.

in the off chance you do have a non lsd then your cheapest option is a mini spool, or welding.

cool thanks mate,

its a NA so yeah no LSD. will just keep hunting for a complete LSD then

Dont be scared of a locker, they are not as nasty as people make them out to be, my diff stuffed up in my old rx7 and a mate locked it, i was too scared to drive it at first (it was raining the day we welded it) because of everything they were saying about a locked diff, but once i drove it i realised its not as bad as people make them out to be, only really notice it on tight round abouts u turns and parking, even then there very manageable, and one your having fun they are very predictable, will always do the same thing at the same point.

Dont know what a spool is worth but if its only $50 then its worth getting one to try it, if you dont like it put it in the for sale thread and get your money back.

Hey guys,

Thinking of doing this to my daily driver... just wondering if you could clear some stuff up for me as ive read through the thread and there seem to be alot of different ideas.

What sort of total shimm should I be looking for?? (2.0mm - 2.8mm?)

Is it better to leave the old shimms in and simply add the extra shimms or to pull the old ones out and replace them with bigger single shimms on either side?

Lastly should I load up each side with the same amount ( 1.2mm either side) or doesn't it really affect it?

Much appreciated guys n awesome writeup.

Cheers

yeh i had a locker in my old onevia. didn't like it for daily street driving (drifts and donuts are awesome tho) too harsh when i do low speed turns/parking etc. the sound got annoying after awhile.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
