Hi Folks

I have ended up with a rotten 1978 2500TC. As my 1975 1500TC bottom end is rumbling and the rear axle and gearbox are whining.

Anyone ever seen this swap done, I was going to swap the engine, gearbox and rear axle over and hope I can get a propshaft to fit!

Regards

Barry

There is a legend of one in a garage somewhere that never sees the light of day. Several folk claim to have seen it, but AFAIK there is not an underbonnet pic available.

Honestly, I don't think it's possible without BIVA inducing body mods, either going through the bulkhead or stretching the front chassis. The big 6 is just too long!

Besides that small point, why would you want to, when the world is full of much better engines? The 6 is very heavy, not massively powerful and suffers from exactly the same crank and thrust washer problems as the 1500 4 cyl you have now. Unsurprising as the 2 are closely related!

Hi Steve

Purely as I have one getting delivered this weekend for £200 and I did not know what to do with it.

As with all things, it looks so easy, but your probably right.

I will strip the 2500TC, it has leather seats in so if there ok I will swap them over and get rid of what I don't need.

Regards

Barry

Thinking logically(!)
gearbox is the same as a sprint, though no adaptor plate/ring. Engine about 50% longer though, so will that go in?
Axle, totally different as IRS. A sprint axle would be a better alternative and uses the same CWP as the 2.5 saloon.

Otherwise teh saloon is still a good buy. OD box worth more than £200, the diff is worth a few bob too, as is the engine.

On this forum from a few years ago, there is a video of a 2000 engine being started in a small saloon.
It was in New Zealand.
It is too time consuming for me to be bothered searching......

There were no body modifications, the engine was early 2000 mark 2 with Strombergs.

You need a Sprint back axle. Propshaft will be Sprint with shortened front section.

According to Ted's lore, the big six engine was destined for the Dolomite body at some point....though the more I learn from his step daughter about other aspects of Ted's conversation, the less attention I pay to the detail!

I did measure up back in the 1990s when I had both TR6 and Sprint and thought it would fit with adaptations to the subframe mounts.

From recent evidence, an overdrive 'box changes hands for a lot more than £200 these days, even without provenance!

Then the single rail O/D gearbox I bought sight unseen from an ebay seller two years ago for £220 was a good buy as it works perfectly! I'm not often that lucky. And Wins International gave me £20 for the non-O/D box - win-win as they say.

Average price for almost any O/D gearbox these days is around £375. I got almost that much from a well known gearbox rebuilder for a TR6 box with A type O/D which was completely without provenance and had been in a loft for 20 years! And that was 2 years ago at least! And another £250 for the completely unproven engine that went with it (admittedly a 150 horse CP unit) and all you could safely say about that was it turned over!

To bump an old thread ...
This has definitely been done - I have a TRIUMPH WORLD magazine from the 90's with this very conversion done to a magenta 1500. The engine fitted in no problem. He used a Metro radiator system for plumbing. The only issue was some minor chopping of the bulkhead to allow him to fit the original Triumph PI system - Gave him a 150BHP Dolly with a straight six (which I know is a mildy-modded Sprint) Unfortunately he stacked the car so it is no more - I can probably dig out the article if anyone wants it...

Hi

Thanks for the info, but sadly me and the sell could not agree on a price, So my 1500 will stay as is, for now!

Probably stacked it from terminal understeer, all that weight up front.......
