garytipping Posted July 8, 2020 Share Posted July 8, 2020 Hi All, Due to a change of plan, I now have the following, all from a MK1 1600, that I need to sell. Engine with all ancillaries. 5 Speed gearbox. ECU Wiring loom, with most connections tagged. Steering column with lock and 2 keys. Complete rear subframe with diff, drive shafts, suspension, hubs and brakes. Front hubs and brakes,. Prop shaft There are 4 x 14" alloys with tyres. They need a complete refurb. I would say the brakes are only any good for exchange. Looking at average prices on ebay they should make around £750. I need the space for incoming parts so £500 collected from Buckingham.

TAFKARM Posted July 9, 2020 Share Posted July 9, 2020 Open diff or LSD? Do you know the ratio? Link to comment Share on other sites More sharing options...
garytipping Posted July 9, 2020 Author Share Posted July 9, 2020 Hi Russ, I don't know the answer to that. It's still mounted in the subframe, do you know if there's a way I can find out? Cheers Gary Link to comment Share on other sites More sharing options...
Stu Faulkner Posted July 9, 2020 Share Posted July 9, 2020 The ratio can be done by turning the input and counting the outputs but to tell what type of diff it is you will need to remove the drive shafts. 1 Link to comment Share on other sites More sharing options...

Cheers Gary if it has bolt on shafts I should be able to tell you if you can post sone clear pictures of the “ears” on the driveshaft mounting flanges.

Thanks Mark, off to the garage shortly, so I'll try and get a decent photo. cheers Gary Link to comment Share on other sites More sharing options...
garytipping Posted July 10, 2020 Author Share Posted July 10, 2020 Hi , Here are some photos of the MX5 diff. I've put the subframe on axle stands and rotated the wheels, they both rotate in the same direction. Looking on line and comparing pictures of the 'ears' it appears to be a Viscous limited slip diff. I've also marked a wheel and the output shaft and rotated the wheel. I would appear this is a 3.6 diff, which I read is rare. As you can see, these are exactly how they came out of the MX5! hope this helps. cheers Gary Link to comment Share on other sites More sharing options...
Mark (smokey mow) Posted July 10, 2020 Share Posted July 10, 2020 Looking at the ears it appears to be a 6.5” CWP Viscous VLSD. These were only fitted to the 1.6 up to about 1993 so most likely a 4.3 ratio. Link to comment Share on other sites More sharing options...
garytipping Posted July 11, 2020 Author Share Posted July 11, 2020 Thanks Mark, I was just turning the road wheel and counting the revs of the output shaft, seemed to be under 4. Link to comment Share on other sites More sharing options...

Ratios would be either 3.6, 3.9, 4.1 or 4.3. the 4.3 was only used on the Mk1 1.6 diff Up to 1993 which is characterised by the larger rubber damper on the prop shaft flange. From 1994 the 1.8 used the larger 7” diff with a 4.1 ratio and then when the detuned 1.6 came out in 1995 this likewise used the same diff. The mk1 diffs had bolt on shafts Whereas from the Mk2 These were push in shafts. the 3.6 and 3.9 ratio were only used in the cars with 6-speed gearboxes and again used the 7” case with push in shafts. 1 Link to comment Share on other sites More sharing options...
