After a long hot summer and a couple of other projects I finally found some time and patience to swap the diff on my Vitesse this weekend. In summary I followed your instructions word for word and it worked like a breeze, no spring lifters required, and no movement of the spring. Called in a couple of favours and borrowed 2 additional trolley jacks (including a heavy weight one for the diff) just to add a bit of additional safety under the chassis, see photo. The larger lifting plate on the heavy weight trolley jack was ideal for holding the diff at the required angle when re-installing, in fact I got it spot on and it went straight in (more by luck than judgement !!) To confirm, if you can remove it, removing the exhaust on a Vitesse certainly aids with access. An additional tip I came up with was to strap a crow bar on the radius arm to lift the drive shafts up and away from the diff, giving me more room to drop and replace the unit. Just need to tidy up the diff paint and take it for a test drive, had the cup of tea ? Couple of photos below Thanks to you and everyone for their advice and comments !! Steve Hi Steve, looks like you might have put a 3.63 diff in your Vitesse. If so how is it compared with the original in particular whats the pull away like in first gear and can you maintain fourth on the steepest of inclines?

Steve Brown Posted October 5, 2018 Author Report Share Posted October 5, 2018 Hi Johny, It should be a standard 3.27:1 diff, at least that's what I ordered. To be honest, apart from a couple of gentle rides around the block to get everything settled, I've not had chance to drive it with any "enthusiasm" yet. Been swapping the wheel studs for the LR Freelander beasts :-) Link to comment Share on other sites More sharing options...
johny Posted October 8, 2018 Report Share Posted October 8, 2018 even more interesting as the 3.27 ratio was never used in the Vitesse which had a standard of 3.89. Your ratio was only used in the lighter GT6 and then only if it didnt have overdrive so its the rarest of the ratios. Is your engine standard? I still have the original diff in my non overdrive Vitesse which I like but would consider going to a 3.63 only if I can go up the steepest main roads without having to drop a gear (I think doing this too often would rapidly finish off my gearbox!)

Nick Jones Posted October 8, 2018 Report Share Posted October 8, 2018 2.0L Vitesse is under-geared from the factory. Having run one for the last 14 years, I'd consider the 3.63 to be what they should have had. My 2L, somewhat modified, would pull a taller diff ratio in spite of having a 0.79 5th gear, though I'm not sure I'd want to go as far as 3.27. For a 2.5 engined car a 3.27 is ideal, though the 3.27 is not the strongest size. Nick Link to comment Share on other sites More sharing options...
Steve Brown Posted October 8, 2018 Author Report Share Posted October 8, 2018 So, the way I read it is as follows Mk 1 Vitesse 1600 = 4.11:1 - Part No. 511350 Mk1 Vitesse 2000 = 3.89:1 - Part No. 518946 Mk2 Vitesse 2000 = 3.27:1 - Part No. 518950 Mine's a Mk2 2L with O/D, hence I went for the 3.27:1 which I presume is the factory spec version. Trouble is wherever I look there's a different view on reliability, suitability etc. I guess that's what makes the classic car world interesting ;-) Link to comment Share on other sites More sharing options...
johny Posted October 8, 2018 Report Share Posted October 8, 2018 I dont know where youre getting your info from Steve but it was definitely: Mk 1 and 2 Vitesse 2000 (both with or without OD) = 3.89:1 As you say theres often many different opinions so trying stuff out is the only way to know and yes is all part of the fun! Dont worry though if you dont like the 3.27 unit it'll be easy enough to sell..... Link to comment Share on other sites More sharing options...
Nick Jones Posted October 8, 2018 Report Share Posted October 8, 2018 AFAIK the only small chassis Triumph that used a 3.27 diff was the non-overdrive GT6. All 2L Vitesses, Mk1 or Mk2, with or without overdrive had 3.89 as did all overdrive equipped GT6s. That's only what the factory did though and the non-OD Vitesse especially is horribly under-geared. The 3.27 will make a much better cruiser, especially with OD. Does make for a fairly high first gear though. Nick Link to comment Share on other sites More sharing options...
johny Posted October 8, 2018 Report Share Posted October 8, 2018 Dont entirely agree there Nick, maybe the Mk2 Vitesse with a bit more power can pull a higher ratio but in my Mk1 I find the 3.89 pretty good. It depends on your driving style and roads I suppose but for me 60 - 70mph is enough and its not mechanical but wind noise (plus handling) that limits me more and thats in a fixed head! True first gear could be taller but I love the acceleration in the other gears and then using 4th for everything else..... Link to comment Share on other sites More sharing options...

Paul Link to comment Share on other sites More sharing options...
johny Posted October 9, 2018 Report Share Posted October 9, 2018 Hi Paul, I run 165/80 13 tyres which make a surprising difference to wheel diameter and dont hit 70mph very often so my engine is doing around 3500revs which seems to suit it quite well Link to comment Share on other sites More sharing options...
Nick Jones Posted October 9, 2018 Report Share Posted October 9, 2018 3,500rpm gives me 85-ish and comes in very handy on the continent where you can cruise for long periods at those speed. Can't disagree with you on the wind noise though! With those tyres your speedo may well be under-reading a bit. Originally calibrated for 155/80 13s (175/70 13 pretty close also). The OP will find his speedo under-reading a lot with a 3.27 diff unless the speedo head or drive gear are swapped to match. Nick Link to comment Share on other sites More sharing options...

All Vitesse 2L were 3.89, non-OD GT6 were 3.27 (possible caveat regarding Mk3), OD GT6 were 3.89 except by special order when 3.27 with OD was an option.

johny Posted October 9, 2018 Report Share Posted October 9, 2018 Well at least we're all agreed on what Steve's Vitesse should have had from new!

That's interesting, where does the special order info come from? Surprised it was offered as an option. A lot of people retro fit OD to their GT6s and don't upgrade their 3.27 to 3.89. Result is relaxed motorway cruising but struggles on inclines. Doug Link to comment Share on other sites More sharing options...
