Z32/S13/S14 - multi-link rear suspension swap

they can ship you coil overs with the z32 mounts as far as I remember tfdave mentioning when I asked.

i already have the Stance kit and s13 subframe i just want to put z32 rear caliper on it and want to be sure before ordering to much part

EDIT: i found all my answer
Z31 stance kit came with s13 sleeve (S13 sleeve match with S13 Spindle)

Q45 diff swap = keep S13 Spindle

Z32 rear caliper swap = keep S13 Spindle

To go 5 bolt : swap the Hub(Z32 NA for S13 diff -OR- Z32 TT for Q45 diff) and keep S13 brake

To go 5 bolt + Z32 rear caliper :
-Parts Necessary-

non-turbo Z32 e-brake/splash shield setup
non-turbo Z32 or S14 hubs if doing 5-lug swap
calipers
rotors

e-brake cables (No information found for Z31 at moment)
brake lines (No information found for Z31 at moment)

Q45 diff on S13 :
-Parts list needed-

A.) (Your Model S13 or S14) differential cover
B.) Q45 VLSD differential
C.) Q45 or 300ZX TT Wheel Hubs (great upgrade for the 4-lug guys who have been looking for a reason to go 5-lug)
D.) 300ZX TT Driver Side Axle (installed on driver side of 240SX) and Infiniti Q45 Driver Side Axle (installed on passenger side of 240SX).

I believe if you are swaping to the Q45 you will need the bearings out of the TT because the axles are bigger than the NAz32?

I just used the s13 frame, Q45 diff, Z32tt alum. knuckles, bearings and rotors, brakes and Z31 lines everything bolted up.

Watch what year of diff you get, the 90-96 q45 is 6 bolt 3.54, and the 97-? is 5 bolt 3.69, although the input shafts interchange.

the Z32 TT hub is in the list for a Q45 diff swap

Your right

Do you need to modify exhaust for S13 swap?

My plan for year 2050 is to have S13 subframe, S13 diff, Ichiba 5lug conversion with GT-R33 Brembo rear brakes. If i can't find i'll use Z32 rear brake setup.

Z32 rear knuckle would be 7lbs (internet fact. S13 iron and Z32 aluminium) lighter than S13, but then coilover mounting for lower rear needs to be change to Z32 also. S13 is different.

This is the q45, z32tt and s13 rear setup quite simple, and getting swapped into my car as we speak, good thing I bought the rearend all ready to just bolt right up, just need to purchase the coils now, stance here I come!

Yes.

Exhaust is much easier to route with the s13 subframe than the z31 subframe.

So true

Q45 suspension option

So I'm going to have access to the rear end out of a 94 Q45.
Unfortunately the car this is coming off of did not come with a rear sway bar, and that Q45 only came with 3 options, no bar, 16mm bar and a 20mm bar. No one makes any after market bars for it.

As I'm led to believe from all the reading i can find on-line, this sub frame is a bit of a combo between the Z32tt and Z32NA frames.
If anyone has a Z32 rear sway bar around that they could measure, could you fill in the measurements shown in the following picture?
This will let me see if a Z32 bar could be used. As all the rest of the suspension linkages are swappable from a Z32, this will allow some available upgrades while swapping into a Z31.



This way i can compare to the mounting points on the sub frame from the car.
Once i get the sub frame I'll post up pictures and measurements for comparison with all the other options.

Got this from a guy on nicoclub.

So now i have a question.. Can the stock shocks/springs from a S13 be used in the swap?
I have a new set of Tokico Illumina's on the front, but my back ones are shot, I’m wondering if a set of Tokico HP's would work on the back, or a set of HTS's.
My Illumina's are on the lowest setting right now, my car is a summer daily driver. No track or racing, just a fun fast car, that’s why I was thinking the HP’s.

if your using the z32 or q45 uprights on the car and you wanna run stock rear shocks, you will just need to get z32 rear shocks. This is what I have in mine while I wait for my coilovers! also you don't really have to run a sway bar in the rear, but you can if you just want the added stiffness.

How does the ride hight set up using a Z32 upright?
I'm considering running a rear bar, just to keep things flat, I'm not racing so i'm not trying to set it up perfect.

with stock z32 shocks and springs in the rear, the ride height is about stock of what the stock z31 suspension is.
