how does your turbo subframe compaire to S12 regular ? I've never actually gotten a good look at the two together.

i'll put it under 2moz mate and let you know.

I've just pulled my N/S S12 half-shaft and trailing arm off and the hubs are different. Stock S12 has 6stud 3x2 but my Z31s are 4x1, same as yours. Also, the input shaft (diff end) is slightly larger and the (spider?) bearing is totally different.
So I'm a bit lost right now.

Can someone confirm a stock UK Turbo comes with the R200 diff ?

just measured the z31 and s12 shafts matey, they both measure 29.5mm and are 29 spline and the s12 is a r200 diff.

We tried to swap over the driveshaft bearing at the diff end and the Z31 input shaft is just slightly too wide to accept the stock S12 bearing ?
Granted I don't have a vernier to measure it though.

edit: did you notice the Z31 has symmetrical driveshafts too ?

Shaun where's that picture you put-up of your z31 sub assembley ?

on second thoughts i got them out and put all six shafts back, i don't think i can get my head round it until i've put the plenum back on and got it mapped.

Well I've done some digging and the 4-stud shaft is a "Double Offset Birfield" type" and the 6-stud is the "Tripod-Tripod" type. Other than the name I have no informatin on one or the other. However, the companion flange in the suspension arm looks to be specific to the driveshaft and the part is listed in the various US nissan parts websites. Looks like the s12 was only ever the T-T type.

ebay has thrown up an open turbo diff which will match with my driveshafts for £95 shipped. I always thought Turbos were LSD type ? Either case that may be my best bet.
