Diy:diff Shimming For R33 Gtst

[bubba]

The one I put in the wagon is still going strong and I give it a VERY hard time.

Pretty good solution for my daily but is a world apart from the 2-way in my Skyline.

What do u reckon of a Full Lock?? Too much on the street? n chop up my tyres easily? I'm thinking of doing this n ordering some shimms n rang nissan n said it will take 2 weeks ex Japan.. or i could get a full lock one for 300bux?? What u reckon?

[W0rp3D]

Search for opionons on locked diff's, i have had one in my old rx7, very predictable and easy to manage, if its only a matter of waiting 2 weeks then i would wait, if its just a track car or a weekender then there is no reason not to lock it, if its a daily then i'd wait 2 weeks.

If you do search for other threads on locked diffs take note of the people who say that locked diffs are deadly blah blah blah, 95% have never had one, then note what people who have had them think of them!

Also how bad is your diff, i was all prepared to do this and my clutch in the one weekend, everything was set then found out i had to wait for shims, put some penrite limslip 85w-140 and now its all good.

Mine would single spin 10-20% of the time so it isnt totally shagged but enough to be annoying.

I wouldn't do it in a daily, mainly because of the destruction to tyres and bushes, also cops will hear/see it if they pull you into an rbt.

Just save for a 1.5 way, a second hand centre is only 500 usually, get the clutches machined and it all professionally installed would set you back maybe $1k max. Do it once do it properly.

i was planning to shim my diff also but all these ppl saying how it chirps and locks up on low speed/tight corners just puts me off.

do 1.5/2ways do this also?

if so then i will just stick with standard or whack in a GTR LSD.

1.5 ways and proper 2 ways don't. Kaaz and improperly shimmed LSDs will chirp and carry on.

I have no idea why people buy kaaz 2 ways that chirp etc, what is the point, might as well just get a locker if they are going to carry on and cause understeer.

Any1 else know where i can shimms besides Nissan n waiting 2 weeks? in Perth of course

The LSD feels a little bit loose.. in can feel it in full turn in low speeds like 1st gear.

No I mean that Unley Nissan here in Adelaide has always had diff shims in stock when me or a friend has purchased them, hence call them up, pay over the phone and get them to send them to you via an express post satchel so they arrive the next day.

Faster than 2 weeks from Japan and probably cheaper.

[nicr4wks]

Main North Nissan Adelaide has also had them in stock on the 2 occasions I've gone to buy them.

i was also going to give this tutorial a shot. ever since this last skidpan day it hasnt locked up since.

and hopefully the shimms bed in a bit before a nice police officer notices it.

Black_CSR, which Nissan did you try?

I always go through Steve at Northside Nissan and I'm pretty sure Grifforelli got some from there last week.

[zamnap]

thanx for the clear instruction...

do you remove the transmission alone?

What do you mean remove the transmission? you remove the diff centre and then open it up and do your shims.

I rang Total Nissan Cannington... Might call Northside then n try my luck.

Does any one have any negative on going to a ~4.6 shim, as in putting 2x 1.49 and leaving the standard .8's in there.?

Depends how worn the viscous unit is (if the shims have scored into it), a 1.49 each side was enough to lock my diff totally for a couple of weeks.

Bubba, has it ever single pegged since shimmed? Also does it still chirp around tight corners?
