Just after a little bit of clarification

Ok so i have a R32 gtst and from what i understand it has a R200 with a 5 bolt halfshaft

Now i know there are many different types of the R200

however my question is:

Can i use any R200 diff with my half shafts? I.e. can i buy any R200 diff which is for a S14/s13/240sx/300zx etc and will it fit my half shafts (5 bolts) with my spline that i have on those half shafts?

Or does each R200 made for each different type of car (32/s14 etc) have a unique splines cut for each one?

I'm gonna say yes and no.

I'll try and explain this as simple as I can.

I had a problem with the halfshafts in my diff, the bolts fell out and they were damaged in the accident (previous owners fault).

I had to go to the task at finding some more 5 bolt half shafts.

Easy I thought, I bought R33 ones and they didn't fit into my diff.

I tried a mates pair of S13 ones and they didn't fit.

I looked at other R32 half shafts and they looked exactly the same as S13/R33 ones too.

The previous owner has put some sort of R200 diff centre into my diff that fits a wierd type of 5 bolt half shafts.

Read my thread (which I got no feedback from), it has pictures of regular half shafts and my 'rare' type :S

Show us what your half shafts look like.

From what i have investigated, however DO NOT TAKE THIS AS GOSPEL - I TAKE NO RESPONSIBILITY IF YOU ATTEMPT THE FOLLOWING AND IT DOES NOT WORK

R32 VLSD as standard is an R200 diff. These all use 2 stub axles (the splined shafts that connect directly to the diff center) which have a spline count of 29, and are different lengths side to side to accommodate the offset of the crown wheel in the diff center (to effectively make both left and right distances from end of "drive shaft" to hub the same length). S13's SR20DET and R33 with VLSD models have the same spline count/config, however I am unsure of length etc. The R33 apparently has larger crown wheel bolts which makes install a R33 R200 center difficult but it can be done with simple sleeving to get a R32 crown wheel on a R33 diff, or drilling and tapping for the reverse application.

S14's however are different as they utilize a 3*2 (6 bolt) stub axle arrangement at 120 degree of separation between corresponding bolts. They still use a 29 spline count and same configuration as the R32/R33/S13 tho apparently.

This effectively means that you CAN put your R32 stub axles in a diff made for an S14/S13/R33 etc so long as it is a diff for a R200. However there may be some slight modification on the crown wheel side of things. However, one thing i am unsure of is whether if you buy an R200 diff, such as a Nismo item, what length the shafts are required to be. Reading one of Bubba's posts, apparently, with this nismo item, the stub axles are the same length side to side and are genuine nissan items, indicating that possibly nismo do away with the different length stub axles and use either 2 of the longer shafts, or two of the shorter shafts. Which one I am unsure of...

If anyone can shed some more light on this, that would be great.

      I definitely agree with you there - I never click on content for cars I would never ever be able to get or compete with/against/be seen next to. Seeing a MX5 compete with a FD RX7 will make people upset though, for sure. Even in 2.5L Turbo form which is pretty grass roots. (or at least as grass roots as classic cars can be) Yes we're all classic car owners now.

      Wonder what the cause is, but here's hoping it's nothing too serious.

      People don't always want builds that are overly expensive, or have engineering/registration/insurance issues and head aches that come with them Whilst big dollar builds, and complicated stuff is interesting to watch, there is only a tiny % of people who would actually use this information, or have the spare finances to drop on said builds, whereas the buy a cheap(ish) cool car, and make it better, with a average budget, that the average Joe or Jane could achieve will always be a winner in my opinion

      Bit of a thread revival, you mentioned wanting a bit more top end before, do you regret not going with the 1.01?

      It's kind of interesting - They definitely do builds that split the difference between what they like and what will generate views and engagement. The NC Platform always surprises everyone in a good way, in an uncomfortably good way some may say. They could throw a LS in there and arguably have the best (and best performing) car of the entire stable. But that isn't necessarily what draws views, because people viewing don't want to accept the vegetables of a LS NC MX5 being a superior vehicle in every way (including fun) than a RB26 240Z. This is also why there's not a lot of content about the GR Yaris (on the web in general). They're too good, yet 'only a Yaris' The community doesn't want certain cars to be as good as they are - to beat their hero cars, and I believe the NC MX5 is absolutely one of those cars.
