Guest james67 Posted July 6, 2008 Report Share Posted July 6, 2008 Hi all just a quick question is a Vitesse diff the same as a TR5 one ?? Regards James Quote Link to post Share on other sites
Chris Mountford Posted July 6, 2008 Report Share Posted July 6, 2008 Hi James; Short answer; No totally different item. Similar items are the 2000 / 2500 / Stag, however they have a different nose section and most have different ratios. The only identical item is from the TR5/6. UK cars have the 3.45 : 1 ratio and US spec cars have the 3.7 : 1 ratio Hope this helps, Chris Quote Link to post Share on other sites

marvmul Posted July 6, 2008 Report Share Posted July 6, 2008 The nose section on saloon cars is different, but it is simply a bolt on extension : it can be replaced by the TR flange. A 2000 saloon has a 4.1 ratio, other models have 3.7 and 3.45. A saloon differential can be a good choice because most of these cars have less mileage and were driven sedately.

Guest james67 Posted July 6, 2008 Report Share Posted July 6, 2008 Hi that’s a good point about the saloons so I supposed the real question is where is a good and reliable place to get it reconditioned James The nose section on saloon cars is different, but it is simply a bolt on extension : it can be replaced by the TR flange.A 2000 saloon has a 4.1 ratio, other models have 3.7 and 3.45.

piman Posted July 6, 2008 Report Share Posted July 6, 2008 Hello Marv, "and were driven sedately." Are you sure??? Alec Quote Link to post Share on other sites
marvmul Posted July 6, 2008 Report Share Posted July 6, 2008 Hello Marv, "and were driven sedately." Are you sure??? Alec Well, not all of them, forgot about you... What saloon is it? Perhaps you know more about the ratio's? Quote Link to post Share on other sites
Alec Pringle Posted July 6, 2008 Report Share Posted July 6, 2008 Big Triumph saloons were often driven anything but sedately, and with a lot more weight to pull than a TR ! I certainly wouldn't bet on a diff being a good'un just because it came out of a saloon . . . Cheers, Alec Quote Link to post Share on other sites
piman Posted July 7, 2008 Report Share Posted July 7, 2008 Hello Marv, my little 2000 saloon as was now has a warmed up TR5 engine on injection, goes fairly well :-) Saloon differentials as installed by the factory, all 2.5 engined models 3.45:1, All 2000 with automatic gearboxes 3.7:1, manual 2000 up to 1975 4.1:1, later 2000 manuals had the 3,7:1 automatic's ratio. Of course, by now they could have any variation of the above. Alec Quote Link to post Share on other sites
88V8 Posted July 7, 2008 Report Share Posted July 7, 2008 Consequent upon this jolly useful thread, I just bought a 4.1 diff ex-2000 saloon, for my TR6. Many thanks folks. Ivor Quote Link to post Share on other sites
Dazzer Posted July 27, 2008 Report Share Posted July 27, 2008 I missed this thread, but yep the diff nigh self destructed on the 2000 auto which I run as an everyday road racer, (started to sound like a leyland bus) definitely not as quick as Alec's TR5 powered 2000, but plenty of torque and you just cant help flooring them. Diff now being rebuilt, as well as manual overdrive conversion, and stage 2(ish) 2000 engine Cheers Darren Quote Link to post Share on other sites
