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

To be honest i do not know 100%, but it sounds like you would be looking for a S13 subframe, and use a Q45 housing, and then you would be looking to use a mixture of Q45/TT axles.
Here is the write up from Nico

G-E Here's what I am planning for my car

1. S14 rear sub frame. (because I have several laying around)
2. Q45 3.54 diff out of 90-96 Q45 VLSD, if you look you will find one with the extra capacity diff cover.
(bolts directly to the S14 sub frame)
3. Lt (drivers side)axel out of the Q45. Used on the Rt (passinger side )
4. Lt (drivers side) axel out of Z32 (300zx) Turbo. Used on the Lt (drivers side)
5. Lt & Rt uprights out of the Q45. You can also use the TT Alum Uprights as well but
You will need the Z32 LWR strut mount as well. This saves you approx 10lbs total.
6. Lt & Rt axel bearings and hubs form the Q45. You can use the TT bearings as well but there are tons of Q45's
in the wrecking yards. You cannot use ths S14 or Z32 (NON)turbo bearings and hubs because here too small.
7. Lt & Rt Q45 backing plates w/parking brakes and parking brake cables. You can the TT parts as well.
8. You can use S14, Q45 or aftermarket control arms. I am going with STANCE S14 Arms/Links/Bushings.
9. Z32 rear brake calipers and rotors or Q45 rear brake calipers and rotors.
(I prefer to upgrage the rear brake hoses w/stainless steel ones)
10. You can redrill the Q45 Diff flange for the stock driveshat rear flange, but since
I am putting a turbo'd LQ4 in my car having a Q45 flange W/1350 ujoints installed on the new driveshaft because
it uses 10mm bolts instead of the 8mm bolts the stock drive shaft uses.

I have done this several times for S14's but if your starting out from scratch, I would go buy a complete
90-96 Q45 rear suspension (less the passinger axel) and buy the S13 or S14 rear sub-frame then just transfer
all the Q45 parts to the S13/S14 subframe install the Q45 Lt axel on the Rt (passinger side) and
install the Z32 TT Lt rear axel on the Lt side and your done.
As a side note install the axels in the bearings before you put the Q45 suspension on the new sub frame
because once all the suspension components are bolted on there isn't room to remove or install the axels
without taking the suspension loose from the sub frame.

If anybody needs some of these parts I have most of them lying around. Or any questions feel free to

you can use either na z32 rear spindles or tt rear spindles, they are the same, also you can use s13 arms, as they are all pretty much the same!

I'm confused about the last few sentences of your write up.
Why do you have to put the axles in the bearings before the suspension/ subframe?

I have changed many times over with out ever having to touch the subframe.

OK so I have verified that the LATER Q45 97+ spindles/hubs have a different spline than the early version, which means it could be a z32na spline, but I haven't had a chance to try any other axles in them to compare

So that begs the question, can we then use the z32na left axle for the later q45 diff swap? That would make the whole mix'n'match easier as TT axles are pretty tough to find.. though if I recall the NA vs TT subframes are different widths, and the r230v might have different offsets on the stubs and/or flange to flange width

I know for sure that the 90-97 q45 axle stubs are the same,minus 5-bolt, 6 bolt as for the half shafts the splines on this year are bigger than the n/a's, I actually used the r32 bearings in my spindles.
I still don't see why if you have the q45 5-bolt, bolt the z32na half shafts on there, then use the s13,z32 na bearings and make it work.

I don't know if they are different lengths, Or not?
If you just take the whole s13 subframe and diff it fits in the Z, I still have the s13 half shafts I could get a rough measurement, then you could see the difference on the z32 na lengths?

I know that the s13 axle stubs are different because the vlsd unit in the s13 is on the oppisite side of that on the q45.

Figured i would post this here for anyone that has the s-13, s-14 sub-frame back there
this site helped me a lot when i did my swap because i wanted the better brakes from the z32 in the rear along with the z32 front

I just got a whole z32tt subframe with everything. I also have a bare s13 subframe with nothing on it. Can i just swap all the tt components, control arms, hubs etc on the s13 subframe? I would like the smallest wheel base as i am trying to put the biggest slick under it i can.

I've never really looked into z32 suspension aftermarket, how does it look compaired to the s13. I would prefer the wider track, but if the z32 has a garbage aftermarket I guess the s13/14 would be the way to go. I take it the q45 is pretty barren overall.

Z32 has just as much aftermarket support as the S-chassis in the suspension.

Subframe is wider on the Z32, and overall track width from hub to hub is wider. But I think the Z32 control arms are just a bit shorter than the S-chassis versions. So one would assume that Z32 control arms on a S subframe would make for a shorter track, which would be good for super wide slicks and/or low offset wheels. But the real thing is that the 2 versions need to be actually measured and compared before you jump into it blindly.

r32/z32 links are similar to s13 with hicas, the balljoint and shock mount are are the two major differences…

q45 is similar to s14

i may have asked this question before.
when i put my new items on my 88T, i want to do the rear subframe swap as well.
can i use a spare of oem s14 spring/shock combos to at least let the car sit on until i put cash down on coil overs?
all i would need to do is buy the upper hats or make some makeshift ones for the time being no?
I want to get the subframe in at least, and have the car roll around.

The issue with the S14 stuff is the height.. they are quite a bit taller then S13 stuff..
If you need i have a set of Z32 struts that you could use, i know the bottom mount is different, but you should be able to figure that out..
I recently started my swap, i just pulled the gas tank last night to have room to mock everything up.

any word on the next group buy? or even a single buy picking up my s13 subframe today.

ok, so can i use S13 stuff? I just need something to keep the car rolling for when I'm away, so if someone needs to move it out into the driveway and move it back into the garage it will be doable.
