Dave Bell Posted October 29, 2020 Report Share Posted October 29, 2020 Hi ...Does anyone know if any Late Vitesse's left the factory with a 2.5L Engine as opposed the usual 2L? Link to comment Share on other sites More sharing options...
Clive Posted October 29, 2020 Report Share Posted October 29, 2020 I know. None left the factory with a 2.5. (at least to be sold, who knows what specials were done in the workshops) Link to comment Share on other sites More sharing options...
Dave Bell Posted October 29, 2020 Author Report Share Posted October 29, 2020 Thanks Clive...Is the 2.5L a modified 2L or a totally different engine? Link to comment Share on other sites More sharing options...
Clive Posted October 29, 2020 Report Share Posted October 29, 2020 Same block, longer throw crank and different height pistons. The very late 2litre(after vitesse, but te last of the GT6's, plus the saloons) even used the same head as the 2.5, but required funny domed pistons. So there are quite a few 2.5 vitesse's about. Some have PI too. I ran a 2.5 vitesse for many years. Makes for a different driving experience, definitely need overdrive, and a 3.63 or 3.27 f=diff to make the most of teh engine (i initially used 3.27s, but after breaking the third, changed to 3.63 which lasted well) Link to comment Share on other sites More sharing options...

Gary Flinn Posted October 29, 2020 Report Share Posted October 29, 2020 How About this one with a 2.5 Engine? a bit pricey though! https://www.ebay.co.uk/itm/Triumph-Vitesse-1971-Show-condition-Last-registered-car-to-leave-the-factory/333758580937?hash=item4db58fc8c9:g:Pg4AAOSwC-1fjIJx Link to comment Share on other sites More sharing options...
Dave Bell Posted October 29, 2020 Author Report Share Posted October 29, 2020 Hi Gary..I have spoken to the Vendor but he isnt open to offers at the moment.Its a great looking example of a Vitesse and he states it has matching numbers. Link to comment Share on other sites More sharing options...
Clive Posted October 29, 2020 Report Share Posted October 29, 2020 I think he means the engine number matches the logbook engine number, not what the car came from the factory with. Seems to be a good car, let down by the stitched (as opposed to moulded) carpet set. The carbs look like late HS4's? If so are too small. Although they could be a late variant of the HS6. And possibly the 2500s inlet manifold (good thing) Link to comment Share on other sites More sharing options...
Dave Bell Posted October 29, 2020 Author Report Share Posted October 29, 2020 Thanks Clive...That would make sense...Think I saw this car for sale a couple of months ago in Inverness...Was thinking of making an offer but I was to late. Link to comment Share on other sites More sharing options...

But it does seem a shame to have fitted a cheap carpet set when so much was spent elsewhere. Domed pistons never seem right to me. All to save having the heads machined, so probably saved a shilling a car. (or maybe the factory line were always putting the wrong heads on engines? ) 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 29, 2020 Report Share Posted October 29, 2020 why has the speedo cable got some sort of correction box on it and the front spoiler corner seals are missing any 2500 conversion its advisable check the engine number so you kknow just what you looking at pete Link to comment Share on other sites More sharing options...

thescrapman Posted October 29, 2020 Report Share Posted October 29, 2020 Nice car, but you could get a convertible Triumph that came out i for the factory, and has PI for that price. Link to comment Share on other sites More sharing options...
Dave Bell Posted October 29, 2020 Author Report Share Posted October 29, 2020 Yes...Think it is overpriced at £15000...If it is still on the market in a few weeks time I might make an offer. Link to comment Share on other sites More sharing options...
Nick Jones Posted October 29, 2020 Report Share Posted October 29, 2020 2L cars go pretty well. The Vitesse (and GT6) Mk2 engine is the best of them. If set on a 2.5 be aware that they really need longer gearing (as Clive already said) and that the standard transmission, gearbox especially, is already on (or beyond) its torque limit with the 2L and doesn’t last very well behind a 2.5. That black one looks nice but £15k..... Nick Link to comment Share on other sites More sharing options...
JohnD Posted October 30, 2020 Report Share Posted October 30, 2020 Maybe it's the way you use it. I've had a 2.5 in the race Vitesses for three cars and more engines. My GT6 gearbox, with O/drive, was built by Mike Papworth (stand up and take a bow, Mike!). The diff is a Quaife, which is bulletproof, IMHO, when I have had OE diffs explode. What has failed has been the rear transmission, the halfshafts and rear wheel bearings. John Link to comment Share on other sites More sharing options...
mpbarrett Posted October 31, 2020 Report Share Posted October 31, 2020 for such expensive car you would expect the battery to be clamped properly! mike Link to comment Share on other sites More sharing options...
Nigel Clark Posted October 31, 2020 Report Share Posted October 31, 2020 The torque of a 2.5 litre engine in a Vitesse or GT6 is very impressive but as has been said, several improvements to the transmission are required. As a minimum, I would suggest the following transmission upgrades: - If retaining the original gearbox, fit the larger mainshaft tip bearing (as done by Mike Papworth and others). - The D-type overdrive is marginal for a 2 litre engine, replace with J-type though this requires gearbox modifications. - Higher ratio final drive. The strongest Triumph gearbox upgrade would be a TR/big saloon unit with J-type overdrive, but there's a bit more work involved in this conversion. Ideally, also fit CV driveshafts. Looking at the photos of this car's underside on eBay, it appears to have a 2 litre gearbox casing but obviously can't tell if it's had the bigger bearing conversion. Also impossible to see of the overdrive is D- or J-type. And I think Rotoflex driveshafts are just visible at the rear. For the top end £15k asking price, I would want evidence that all the required transmission upgrades are included. Otherwise, the gearbox and overdrive are unlikely to last long. Which is why I'm in the process of upgrading the transmission on my 2.5 litre GT6! Nigel Link to comment Share on other sites More sharing options...
