Can I just purchase regular SPL s14 bushings or would I need to buy the 350z conversion bushings (example gktech conversion bushings).

Thanks for the help in advance.

Conversion bushings. Unless you wana do fabrication.

Doing more research I don't think that is the case. Since I am running a stock s14 diff still and purchased the output shaft adapters for the z33 axles which will fit onto the s14 diff, regular diff bushings will work...at least this is what I am being told.

If I was to run an actual z33 diff then I would need the conversion bushings also...

Oh I didnt read you had the stubs, yes just normal bushings.

So with this info, if I'm running an S14 subframe at a pretty close to stock ride height with the Maverick dual caliper plates (space the bearings off the uprights 8mm) I shouldn't need the spacers that get sandwiched between the axles and diff stubs? Because I am waiting on them to be back in stock but I'd also like to throw this rear end back together...

You could get away with no spacers. Thats if ur at stock height and new/refub axles..old ones the boots tear when stretched

Cool, yeah the boots are in good shape and the subframe is setup so it's damn near stock ride height. The z33s are in the future but I just want to get this thing going without another fucking project within this project.

Thanks

if someone would just make some stub shafts that were 15mm longer that'd make things a whole lot more convenient...

Interesting - when I spoke to Villains Nate specifically noted that axle spacers would not be necessary with this application, did the drop knuckles change that? I noticed you first installed them in 2017 with a 4.3 and no issues, then put in spacers in 2019. How's the setup holding up so far?

My car is pretty slammed and the drop knuckles push the knuckles further out, but don?t help the axle geometry at all, so not only are they at a shitty angle, they?re also over-extended. The 10mm was pretty much necessary for my setup. Since doing the 10mm spacers and changing out the axles I haven?t had any issue other than the axle nut at the hub coming loose regularly because I cans rock the cotter pin with the spacers.

Would it be better to just have Villains make you a new set of stubs that are 10-15mm longer by the axle flange? Then you wouldn't need that spacer at the hub spline.

Yes

That's what this was supposed to mean, but I didn't articulate very well haha

This was essentially why I asked. I'm on the driftworks geomaster rear knuckles and I love the correction on the arms but I'm worried about compatibility issues when running the villains stubs because these knuckles do push the hub out just a bit, like deolio described. I'd like to avoid using the spacers but that may be the way to go unless they'd like to extend the stub a bit, but I'm not sure if that's possible granted they probably have a jig for this - let's see what they say

PoorMans180SX · 05-13-2021, 09:14 AM

Weir stub axles seem maybe a little bit longer? Hard to tell as one has the oil seal trim thing. Double the price though.

Corbic · 05-13-2021, 05:44 PM

Just in case I missed it - a Z33 Dif is no stronger then the older S/R Diffs, correct? It's only the axles that are an improvement, correct?

Can I bump this? Curious as well.

?Haha? for you

PoorMans180SX · 05-19-2021, 05:48 AM

Z33/34 diff is an R230, so yes, it should be physically stronger. Unfortunately it's up in the air whether or not the output shafts are stronger, as there's not a lot of people making enough power to actually break them.

Z33 axles are definitely stronger and Z34 even more so as they're 30 (IIRC) spline at the hub side.

Technically the strongest Nissan diff you can put in your car is a Z32 TT diff (R230) which has 32 spline outputs, and then DSS will modify them with 300M shafts. Not really sure how you'd break that this side of a Formula D car...

Got it, thank you for clearing that up. I am already at the R200 early Q45 3.54 gearing using the z32TT hubs, one z32TT axle and one q45 axle. I?ve been told to change to a z33 but wanted to see the gains. The ratio is fine for me with the LS/T56 but I?m open to ideas. Especially with Z32TT axles being scarce and pricey. I have one spare ready to go I got here recently but once that one goes I?ll be concerned haha.

You should be able to directly swap to Z34 axles as far as I know.
