  1. I think "Vitesse Engineering" are currently developing an MX5 gearbox conversion for the GT6, which would also suit the Vitesse. I am thinking of going down that road if it comes off. https://www.vitesse-ltd.com/ (Spitfire 2.5 efi with 3.63 diff)
  2. Found this on the web recently. https://www.triumphexp.com/forum/spitfire-and-gt6-forum.8/j-type-od-for-spitfire-vs-gt6.1332997.1854586/page-3#msg-1854586 First post on page 3.
  3. Hi, It might have already been suggested but try disconnecting the electrical side of things to see if the issue stops?
  4. Thanks for all the advice. I will have a go at getting a refund.
  5. Hi, I enclose my correspondence with Bastuck Dear Sir,Thank you for the message. We are not aware of any problem with the shafts so far. When mounting the shaft, always check the clearances. If this had been done correctly, the problem would have been detected immediately and no damage would have occurred. Of course, you could have returned the shaft or adjusted the Bush accordingly. Perhaps the problem was not with the shaft but with the installed bush.Please accept our apologies. Unfortunately, we cannot help you.Kind regardsTeam BastuckAndré KronbergNachrichtentext:Hi, I bought one of your type D overdrive gearbox mainshafts for my Vitesse gearbox. The 2nd gear bush & cog seized onto the shaft. Measured your shaft and it is slightly over the recommended max diameter (22.215mm). Max should be 22.194mm. Gearbox badly damaged. Can you help. Advised to contact you by TSSC member.
  6. Hi, Thanks for the various responses. I sourced a spare non-overdrive gearbox from triumphspitfirespares which seems to be in very good condition. I used the internals and built them round another OD mainshaft which has slight wear on the tip. I am hoping a good machine shop can salvage the bastuck shaft by grinding it to the correct tolerances and hopefully rebuild the box over the winter with the salvaged or another replacement od mainshaft. Any recommendations of a source for a good mainshaft would be helpful. Thanks
  7. Bastuck replied and said I should have checked the dimensions. No further assistance offered. Older and wiser now!
  8. Thanks. Sent an email to Bastuck. Will let you know what I hear from them.
  9. Hi Johhy. Original shaft measures 22.175mm, Bastuck shaft 22.215mm.Thanks for the info. Waiting on a replacement gearbox to see what parts I can use for rebuilding. Will let you know how I get on.
  10. Will check when I get a chance. A cheap micrometer but good enough to check there is a difference between the old & new shafts.
  11. Hi, Has anyone had any issues with Bastuck mainshafts for type d OD vitesse/gt6 gearboxes. My second gear cog & bush seized solid to the shaft and stripped the teeth off the layshaft cluster. Measured the Bastuck shaft and it is about 0.03mm thicker than the original. The bushes were a bit stiff to push on to the shaft when I fitted them but I assumed the original was worn and that they were meant to be a tight fit?

    Thanks for the reply Nick. Will let you know how I get on once I get the wide band fitted and the roads get cleaned of salt. DJN

    Hi Keith, I think my cam is a standard early TR6 pi cam. Will be fitting a wide band O2 sensor soon and will have another go at set up. No rolling roads anywhere near me but planning a trip to one up in Wick later in the spring to hopefully smooth things out. DJN

    Hi Nick, A wide band O2 is on my shopping list so I will have a play around with things once it is fitted. Bonnet clearance is tight but it shuts and so far so good. My throttle body is a 46mm. Thanks for the reply and I will update my progress after I get to the bottom of my noisy back axle area. DJN

    Hi Roger, Yes, it came with the kit from "Trigger Wheels".

    Hi again, Re Nick Jones post, did you manage to smooth out the issue with lumpy tick over and trickling along in slow moving traffic? My set up has the same issue, fine when cruising but not happy at very low speeds. Fuel consumption improvement similar to yours and pulling well from low down the revs. It has done about 3000 miles since first run with out any issues. I have tinkered slightly with the maps but I don't want to get too far off base. I hope to get on a rolling road sometime in the future but the nearest ones to me are about 200 miles away or so. Currently using a narrow band O2 sensor but considering getting a wide band sensor? Thanks for the various posts and info. DJN

    Finally starting to get a few bits together. Gone for microsquirt and CP pi inlet manifolds. Hope to start fitting in the next few weeks. Interested to hear any advice, especially on bonnet clearance issues and fuel pump stuff. Up and running. A bit of tidying up and tuning to do but running well already.

  19. Hi, I have been thinking of installing efi in my 2500 spitfire. Looking at the list of parts needed I was thinking of getting the microsquirt kit first and sourcing the other bits and pieces as they become available. Would it be worth while installing the microsquirt kit first just for the ignition control. I currently have a luminition kit installed. Any advice would be very helpfull. Many thanks in advance. DJN
  20. Hi again, Found this on another forum. Hope I am aloud to paste items from elsewhere to here. "Paul" contacted "Overdrive Spares" and got this reply. Hi Paul Ignore what it tells in the manuals it is not correct for every unit and would have only been correct when the overdrive was new The best way to explain it is thus with the operating valve /spring /ball/plug fitted if you take hold of the brass lever and push it towards the solenoid you will feel a light spring pressure if you rest your finger on the start of the spring pressure and energize the solenoid when set correctly the lever needs to jump 1.5 to 2mm towards the solenoid when the solenoid is not energized you should have some free play in the lever regards Dave. Has anyone come across this info before. Will try this method of aligning the lever when I get a chance and will report back. DJN
  21. Hi, I would be interested to hear how you get on with this. I have the same issue. The first time I select overdrive from cold, there is a slight delay in engaging. Fine after that but always releases with a fair thud. (spitfire 2500, d type OD)
  22. Every time I click on a topic I end up with the last post/last page first and have to scroll up to get to the start. Have I got a setting wrong? This didn't happen on the previous version of the forum. DJN
  23. Hi, I came across a post on some website a while back re different float bowls front and rear on the vitesse/gt6 engine set up with SU carbs. The reason given is because these engines are not mounted horizontally (lower to the rear) and as the front bowl is forward of the carb body and the rear bowl is rearward the fuel levels at the jets, if all else is equal, will be different. (higher at the front jet and lower at the rear). Using a different bowls front and rear (I don't have the part numbers to hand but could look them up if needed) will level things up. DJN
  24. Hi, I don't think it can be done. Once you have gained access to the overdrive, a few extra nuts and bolts removed and the whole gearbox will come out. Let us know how you get on if you manage it. DJN
  25. Seem to remember having the same problem in my Vitesse many years ago. As mentioned above, make sure fans are switched off before you switch off the engine and see if that stops the running on.
