Ok a friend gave me some rear hubs knuckles and ebrake from a z32 tt now I know I Can't use it on my 240sx just llike that but is there a way I can use it and wut would I need to change axles and rear diff rite just put the cover from the 240 rite?

Google is your friend, there is atually a website dedicated to the 300ZX brake swap

norcals13 · 05-15-2012, 02:25 PM

Try google only think it tells me is that I can't use it but I heard I can just have to change some parts

ghoti · 05-15-2012, 02:51 PM

Just get NA hubs wills make everything much simpler.

The TT hubs will not work because the the spline in the hub is much larger than the NA hubs which bolts on to the stock axles. The TT axles will work but they are 1-2 inches shorter or longer I cant recall. The diff that will work is the NA VLSD since it is a R200v same as stock and the same 4.083 ratio. The TT diff won't work since it is a R230v (means its bigger) though some say they've made it work. Also the gear ratio on it is retarded to use on a stock 240,3.69 final drive.

2muchboost · 05-15-2012, 07:46 PM

As stated before....you can make them work by using a z32 tt driver side axle on your driver side and a q45 driver side axle on your passenger side....but this is completely pointless unless you are going to run lots of power. The stock axles and hubs are fine for most. I would sell those and make some cash

norcals13 · 05-16-2012, 12:18 PM

Thanx guys im just gonna go with n/a then anybody interested in does hubs then lol

*wangan_cruiser* · 05-16-2012, 09:40 PM

go find yourself both driver side axle from a tt model. tt hub has more spline count compare to NA model.

norcals13 · 05-17-2012, 02:15 PM

If I was to get both driver tt axles I would need the diff from a tt too rite?

*wangan_cruiser* · 05-20-2012, 12:11 PM

yup or any jdm vlsd

2muchboost · 05-20-2012, 06:53 PM

Only reason to upgrade to the larger spline count setup (z32 axle [D side] + q45 axle [D side]) is to minimize the chances of snapping an axle which is not common unless you are making some decent power besides the ability to utilize the different gear ratios. For 90% of the people and their projects....you will not need to do this. However, if your planning on building an LS swapped car or a high HP 2jz setup or something like that....then hang onto these because they will def come in handy later.

If I hadnt bought mine a month ago I would have taken these of your hands. If you do decide to sell though...shoot me a pm. I have a few people who would benefit from these.

240zach · 05-20-2012, 07:52 PM

`just a quick question, the 300zx na rear hubs will be straight bolt on or no.

norcals13 · 06-04-2012, 09:41 AM

Ok so if I got the z32 tt rear set up can I just change the hubs to the na or do I have to change the knuckle too?

you must be talking about importnuts site. that was the definitive z32 brake swap guide back in the day before it was discovered r33 skyline cables/z32 2+2 cables could be used for rear ebrake instead of splicing cables.

Z32 NA Rear Hubs bolt onto stock S13/S14 uprights without any additional mods.

If you want to retain your stock axles, you'll need a pair of Z32 NA Hubs/S14 Hubs, etc. I'm assuming you're talking about getting the entire upright off of a TT Z32?

norcals13 · 06-04-2012, 10:29 AM

Yea I got the whole set up hubs ebrake set wuth cables rotors calipers and uprights I know does won't fit on a 240 cuz the axles r shorter or something like that rite? And the na would fit so do I just need to change the hubs so everything go in instead of having to buy everything? And the cables r they difrent the na and the tt?

If you're swapping a complete Z32 upright onto your S13/S14, you'll need new cables (not sure which you need) and a new lower coilover mount/new rear strut. The Z32 has a fork style mount vs the S-Chassis eye mount.

If the Z32 upright is from a TT then you'll need to swap the Hub to an NA one.

norcals13 · 06-05-2012, 12:49 PM

Ok koil thanx so I need to change the lower coilove mounts ?

norcals13 · 06-12-2012, 10:18 PM

Anybody knows if the z32 tt ebrake set up will work on na hubs

E-brake assemblies are interchangable. It is the chassis that determine which cables you need to use. For S13 you need z32 2+2, for s14 you need R33.

Difference in z32 knuckles:
TT has HICAS so the toe arm / tie rod has a ball joint and NA has normal toe arm so the bushing is different at this location on the knuckle.

Difference in z32 rear hubs:
TT has larger spline count and will only work with TT/Q45 axles. The NA hubs accept s13/s14/j30 axles. The hubs themselves will directly bolt to s13/s14/z32 knuckles.

Difference in z32 axles:
TT has larger spline count at the wheel end and will only fit in z32 TT or Q45 hubs. The flange side is 6 bolt split pattern and fits TT or Q45 diff output flanges. NA has split 5 bolt pattern that match J30.

The only way to use TT hubs is to use a q45 diff which is an R200 housing but with the larger split 6 bolt output flanges, this requires the use of q45 drivers side axle and TT drivers side axle. Unless you have a need for using these parts just get NA hubs and use whatever knuckles you want.

ka4life87 · 06-13-2012, 01:03 PM

I jumped into this thread a little late but im actually in the same position. I recently got a complete z32 tt setup that I wanted to put on my s13. I got all 4 calipers, lines, rotors, rear knuckles and e brake assemblies and even axles for 230 bucks, couldnt pass it up. I was aware that tt and n/a rear assemblies are different after doing some research, im just curious about you mentioning the ebrake hardware is the same, from what i found the tt and n/a are different, if thats the case then I would have to use the tt knuckels but only thing im doubting about is the rear diff on my s13, i do have the factory vlsd and hicas but im not sure if the tt axles will match up since they are 6 bolt star pattern, havent had a chance to check my diff or anything on my 240 since i got this setup.

NismoPlsr · 06-13-2012, 05:33 PM

The e-brake assembly is the same between z32 NA and TT.

For your situation I would recommend find some NA hubs and just do the brakes. You cant use the hubs without doing a Q45 diff swap that uses the TT and Q45 axles, or use the knuckles without getting z32 fork style shock mounts for your coilovers (if you are using some). I'm not sure if the s13 HICAS arms will bolt up to the z32 HICAS toe mount on the knuckles either.

ka4life87 · 06-13-2012, 06:52 PM

Got it thanks for the clear up, just havnt had the time to take the car apart, sounds like too much hassle to use the 300zx knuckles so just gonna sell them

eek · 06-13-2012, 07:48 PM

Its a hassle if your not worried about unsprung weight. The z32 knuckles are alum IIRC and are lighter than the stock 240sx knuckles. But you will need to run a different lower coilover bottom to use the z32 rear knuckles. I think megan and spl carry them if you buy their coilovers.

The entire e-brake (drum assembly) can be used from either z32 tt/na or skyline over to you 240sx rear. Make sure you have alot of time decent set of tools (impact gun will save you alot of time) and some patience. Alot of the rear assembly I have seen lately are just beat to hell with grime and rust.

As for a working ebrake, if you have a s14 chassis R33 skyline ebrake cables will fit perfectly. S13 IIRC uses z32 2+2 ebrake cables. This way you do not need to jimmy rig and splice up the cables.

The Definitive 300ZX Brake Swap Paqe
This old school guide helped me out when I did mine way back when. I'm sure it has helped tons of others as well.

Like others have said, ditch the TT hubs and run the Z32 NA hubs or source S14 SE rear hubs. If you plan to run a r200 VLSD from a jdm s-chassis/z32 NA/J30 you will need to run the jdm 5 bolt axles or j30 axles like I did. Or you can just re-use your stock axles and run your stock diff and then weld it like many ghetto people do or get yourself a nice 2-way and not deal with having to source axles for that vlsd.

While your at it, it would be a good time to change out and rear suspension arms, install subframe collars, diff swap if you have a vlsd (new diff oil of course) or whatever you plan to use, install a z32 brake master cylinder so you don't have a mush brake pedal, and do the front brakes to z32/skyline/some brembo off whatever car/q45/etc, change to s/s brake lines and have a buddy help you bleed your entire brake setup with some nice fluid like ATE super blue or whatever floats your boat.

Well at least that's what I did, took a shit load of time, hunting around for parts, but after 1 full solid day of wrenching after I gathered all the parts at least I don't have to think about or touch that shit ever again.

norcals13 · 06-13-2012, 08:13 PM

Ok guy I need some help I just took the ebrake (drum) off my z32 tt assembely to put the na hubs on the tt it has a thing I don't know wut is called but is were the 2 springs hook up to on the tt the hub actually goes to the bottom of that and the na doesn't I don't know if I can just put it like that or not

norcals13 · 06-21-2012, 11:24 AM

Do I have to change the maste cylinder wen I do the brake swap or not really?

Really...? Somebody posts a link that answers ALL of your questions & you still find a way to ask a question that there's an answer to in that link?

crewchief05 · 11-07-2013, 07:07 PM

sorry to open this back up. I just need some clarification.

I plan on using the z32tt/q45 axles and q45 diff.

My question is will that fit into the stock s14 knuckles(uprights)? or do i have to use the TT or q45 knuckles. I know without using the axles they are to short or long regardless. But again if I am using the axles and hubs will they fit into the stock s14 knuckles?

No one ever mentioned this or asked this question. i searched.

Just the TT or Q45 hubs, they bolt up to s14 knuckles.

crewchief05 · 11-07-2013, 08:09 PM

so y does everyone mention the uprights? are they just wanting to use them just because?

ghoti · 11-07-2013, 08:41 PM

because Q45 hubs are pressed onto the upright/knuckle like J30s. You have to use the whole thing.

Z32 TT hubs on the other hand can be bolted on.
