Differential questions

[dirt114]

I'm currently in the market for some drivetrain changes one both my na->TT swap z32 as well as my stock s13 (89-90) hatch.

Keep in mind I have a good cheap source for used z32 parts. much more so than other cars like the q45.

I believe the diff in the z is wearing out and humming/whining and I also want a taller gear ratio. SO, I'm curious to know if the internals in the na and tt diffs can be changed out. for example the ring and pinion gears. If so I may be able to get a used tt diff and use its parts to rebuild my existing diff to be in better condition and with the ratio I want. If not, anyone got some other solutions that would be somewhat affordable? Im not looking to get a $1000 diff here.

For the s13, I just CANT STAND the open diff lol Im used to my z32's lsd that ive played with for years. also I want to have a 5 lug conversion for the s13 too so I like the idea of teh q45 diff and axle/hub swap but again, I dont have any idea where to get one. I'm not really planning on building the s13 for huge power so im not worried about breaking axles so id be interested in anything that gets an lsd in that thing that has compatability with easy to find 5 lug hubs of some sort.

Any and all information/specs/links/sources/solutions about all the nissan diffs are welcome and apreciated :hsdance:

IIRC everything you just mentioned is an R200 flavor of diff, aside from the Q45 which I think is bigger?

[dirt114]

yea, I think the q45 and z32 tt use the R230 and the NA z32 and j30 use the R200 BUT idk if all the splines/shafts/axles are the same shape/fitment on the different cars they go on... (and idk what part is called what lol im a noob)
also idk if the r230 internals will fit in the r200... if that was all yeses id be golden for everything but from what ppl have said on 3zc, the ttz diff is not a bolt in affair for the na z yet the q45 diff is...

if anyone is on 3zc i started a thread there and found a few solutions for my z32 and posted the info. still not sure on the s13 situation. if the z32 na R200 will bolt right into the s13 then I think I can just use the na z32 hubs and axles as well. can anyone confirm this?

also, what are the common ways to swap the front hubs to 5 bolt? prefferably without having to swap any brake calipers or pads or lines...

z32 NA diff will bolt into s13 with s13 rear cover, that is what i have in my s13.
also you have to use J30 Axles, z32 is to long.

are you saying do this with z32 hubs as well? and two rear 2+2 ebrake cables (think I read that somewhere) if I use all the z32 rear brakes? Thanks again

yes for 5lug conversion you can use the NA hubs.

but u have to use J30 axles or JDM 5 bolt s13 axles. z32 will not fit, they are too long.

for e-brake...2+2 cables (you will have to make a simple bracket to mount cables..i can post pics of mine if you need)....backing plate and all hardware..rotor and caliper. alll will bolt up to stock s-13 upright.

this is from the front looking back, all it is, is angle 1"x1" that will move mounting hole back.

for the front i used s14 knuckle, s-14 hub and s-14 front lower control arm.

Perfect. Thanks!
