AidanT Posted March 20, 2018 Author Report Share Posted March 20, 2018 Thanks Dave I see a plan coming together! Maybe once the right engine is purchased refurb the head first, and possibly swap over on to the ME as a first step! Aidan Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 20, 2018 Report Share Posted March 20, 2018 You cant fit a std mk2 head on to a ME engine or any with dombed pistons Well it will ' fit 'but comp ratio will be far too high , and piston may even contact the chamber Its shallow head and flat tops Or deep head and domes In simple terms Pete Link to comment Share on other sites More sharing options...

It has flat pistons. At and after ME50001 the block was common with the 2.5 Litre and domed piston were fitted. Plus it had the 150CDSE carbs and not smiths breather valve.

Algy Posted March 20, 2018 Report Share Posted March 20, 2018 Some of my engine build on the Bond might help you, as and when I progress the egine rebuild. It is a Mk1 but most of the build is the same. I will try to take more photo's to help. Just like you I am trying to build this engine in the spec it was in when I got it (as it was in the 1970's when raced), which was tuned but not hot. 1 Link to comment Share on other sites More sharing options...
AidanT Posted March 20, 2018 Author Report Share Posted March 20, 2018 Hi I am now going to add more confusion! HA or maybe not! I had to double check my engine number and its actually: ML24700HE So would that be Domed or Flat Pistons? Maybe I should get one of those camera things from ebay and check?

Colin Lindsay Posted March 21, 2018 Report Share Posted March 21, 2018 Aidan - try this one: https://www.ebay.co.uk/itm/Triumph-GT6-Vitesse-2000-Mk2-Original-1998cc-Engine-in-superb-order/123024776503?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D43782%26meid%3D1465ab649a8e492aa81d26f2829725ae%26pid%3D100005%26rk%3D5%26rkt%3D6%26sd%3D222889642776%26itm%3D123024776503&_trksid=p2047675.c100005.m1851 It might save a lot of bother in the long run...

AidanT Posted March 21, 2018 Author Report Share Posted March 21, 2018 Hi Colin Yes I have seen this one. The trouble is its still a 2000 saloon engine , so if I understand all the other posts above will have a heavier flywheel and not the best camshaft? The idea is really to do the work myself as a project, to enjoy the process and end up with something I have achieved Aidan Link to comment Share on other sites More sharing options...
JohnD Posted March 21, 2018 Report Share Posted March 21, 2018 The change to domed pistons for gt6 came at KE10001. Does that help? And the reason was so that Triumph could use unmachined 2.5L heads on 2L blocks. I can't recall how falls 2.5 L head is, but look it up?

dave.vitesse Posted March 21, 2018 Report Share Posted March 21, 2018 My understanding is the ML also had domed pistons. It is a late 2000 Saloon engine. As a double check I looked up the piston part numbers and both the ME50001 onward and ML engines have the same pistons.1.e. Domed. Dave Link to comment Share on other sites More sharing options...
dave.vitesse Posted March 21, 2018 Report Share Posted March 21, 2018 As Pete has already stated you cannot interchange non domed and domed piston engine heads In other words you cannot used the ML head on a Vitesse/GT6 Mk2 engine or the other way around.

AidanT Posted March 21, 2018 Author Report Share Posted March 21, 2018 Hopefully a positive to this number HC52164HE from my list that's a mk2 vitesse would this be a good start? Aidan Link to comment Share on other sites More sharing options...

The idea is really to do the work myself as a project, to enjoy the process and end up with something I have achieved Aidan Yes, saloon has a huge flywheel which is twice the width of the GT6 version but quite smooth running; I ran my GT6 on one for an age (until I realised!) and it made the engine very relaxed, but obviously at the expense of acceleration. Once I swapped for the GT6 version it made the engine quite light and almost insubstantial feeling. Very easy to swap over, though. Same with the camshaft; it's also a relatively simple swap. 1 Link to comment Share on other sites More sharing options...

It's got minimal end float and without ancilleries so I will try and get it at a good price Aidan Link to comment Share on other sites More sharing options...
AidanT Posted March 21, 2018 Author Report Share Posted March 21, 2018 Thanks Colin This thread has been a really useful learning curve for me. I would never have realised the difference in the flywheel I know they are heavy so the 2000 doubly so. Thanks for the picture it certainly makes it stand out! Does this impact on the clutch throw out? Aidan Link to comment Share on other sites More sharing options...

Looking at the pictures it is a nice paint job but looking at the picture with the big ends (picture 10) the shells are not the same!? So has been rebuilt before and not to a good standard. A good paint job is not a guarantee of a well built engine, so from the photo's the engine for me would need a full rebuild on, with possible regrind and rebore; at the start price without all the other expensive bits on the outside, the price I think is on the high side (but that might be being tight).

Pete Lewis Posted March 22, 2018 Report Share Posted March 22, 2018 what the heck is that oil pump pick up ??? and the engine is big saloon so the front engine plate is incorrect for any Vit GT6 has to be swapped or have them cut off Link to comment Share on other sites More sharing options...

AidanT Posted March 23, 2018 Author Report Share Posted March 23, 2018 Hi Pete I never considered this as an option but the many comments on this engine are none the less useful. If I manage to buy the one I have found I will add some photos of it on here and will look for ideas on the best routes for reconditioning Aidan Link to comment Share on other sites More sharing options...
AidanT Posted March 26, 2018 Author Report Share Posted March 26, 2018 Well missed out on one I was looking for but I'm sure there will be others. Can I ask you all a question. What price range should I be really looking at ? Aidan Suppose I should put a parts wanted request in! Link to comment Share on other sites More sharing options...
