  1. Does the MX5 box even have a speedo drive cable? I would have thought it would have an electronic sender. I have a solution for this problem but I warn you, it's absurdly complicated.
  2. The usual approach to this type of match up would be to retain the TR flywheel and clutch cover with an MX5 clutch plate. Will the Mazda bellhousing accommodate the TR flywheel or have you got a different plan? What are you going to do about a speedometer drive?
  3. Hi Marco. I didn't need an adaptor plate. I was lucky in that two of the boltholes lined up so I had a head start. I had to remove 8mm from the front face to allow the input shaft to engage the crank. New dowel holes and the remaining bolt holes were drilled using the thin engine back plate as a template. I also had to make an adaptor to re-position the starter motor.
  4. Looks like an MX5 box. I've been involved in similar gearbox/engine mismatch shenanigans myself. Not quite such a mismatch as yours though. First time was mating a Toyota T50 to a 3SGE engine it was never intended for then latterly putting an IS200 AZ6 6 speed box on the same 3SGE engine. The first was achieved by full measurement of both parts on a very, very expensive CMM machine and CNC machining to suit. One advantage of being a CNC machinist working nightshift. Fitted like a glove. Modifying the AZ6 was a more "hands on" approach as I am now retired. Air-hacksaw, grinder etc. That fitted like a glove too! The trickiest part was design and fab of a "reverse remote" to move the gear lever forward five inches.
  5. Who is the follicly-challenged guy looking under the rear of Mike Walker's car, Mick?
  6. I found these pics earlier today so I thought I'd post them here. It's Silverstone in the late 80's. Most of the usual suspects are there. How many can you name??
  7. If I had a TR3 I would fit period lights, regardless of cost. You might also consider uprating the charging system.
  8. From the MOT manual... You only need to inspect: front fog lamps fitted to vehicles first used on or after 1 March 2018 the 1 rear fog lamp which must be fitted to the centre or offside of vehicles first used on or after 1 April 1980 This would suggest that any fog light fitted to any TR older than 1980 should not be inspected. As regards a single front "spot lamp" I can't see any direct reference. The manual seems to suggest that only "obligatory" lights are tested and the additional single lamp would not be included. Vehicle lighting regs may well be different. The above only applies to the MOT test.
  9. I've got one of these 360 cameras on my mountain bike. Cost me the princely sum of thirty quid. Brand new. If the footage is processed correctly prior to uploading it allows the viewer to change the viewpoint whilst watching the video. Just "drag" the image round with your mouse pointer or by fingertip if viewing on a smartphone. I found the processing part tricky and my uploaded footage loses quality. Here's some racing footage (not me) to show you what I mean. It's witchcraft I tell ye!
  10. I fitted an aluminium flywheel during my recent engine build and came up against the "ring gear bevel" issue. I was using what was actually a front wheel drive engine and turning it through 90 degrees into RWD format. The RWD starter engages from the opposite side of the flywheel, so no bevel. As Graham H has already stated, you can't just turn the ring gear round so I hand ground a new set of bevels in the correct place. Not difficult at all, especially when you use a potter's wheel as a handy rotatable work surface! The amount of metal actually removed is miniscule. The benefits of the light flywheel are greatest in first gear and diminish progressively from there. I had discussed the potential benefits with Peter Burgess and he said it would be really worthwhile. He said it shows up on the dyno.
  11. Hi Pete. I don't know if my car even qualifies as having an "interior" since it has very low cockpit sides, no doors and no roof. It's like sitting in a wind tunnel stuck on "Full". If there are any fumes being diverted my way I can't say I've really noticed too much and my brain is already addled anyway. Most kit cars of the "7" ilk have bonnet louvres like mine, Caterham included and they ( Caterham) have been through full manufacturer approval. Most of the others have been through the IVA test. I'm sure that my car already had plenty of heat vents, including the OEM side vents you spotted. I added the bonnet louvres on aesthetic grounds. I do "nod" to safety on occasion including fitting full "Schroth" 3" harnesses but the car itself would probably scrape an NCAP rating of -10. It has 200hp+ and weighs about the same as a classic Mini. If I really sat down and thought about it I wouldn't dare drive it at all, even slowly. The same reasoning applies to a lesser extent to TRs too. I guess it's risk versus reward at play.
  12. I made a new ally bonnet for my car and went to Shapecraft in Hinckley to get the louvres put in. The work was spot on and a lot less expensive than quotes I got at the spares day. Might be worth giving them a call. bonnet45 by Geoff Lee, on Flickr 005 by Geoff Lee, on Flickr
  13. All cranks are balanced from the factory, some likely better than others. During my recent engine build, a 1995 Toyota 3SGE 2 litre, I insisted on crank and flywheel balancing, despite being advised that it wasn't necessary. Guess what? It wasn't necessary! The crank came back with two tiny, tiny drilled dimples. One was little more than a dot punch mark. The flywheel had just one tiny dimple. A 60's crank may benefit though. Bobweights are un-necessary on a inline 4 pot. Or an inline 6.
  14. Hi Marco. I'd leave it to the experts. An incorrectly balanced crank/flywheel could easily wreck your engine. A detached flywheel could chop your feet off! DIY balancing must be near enough impossible. I'd be amazed if it can successfully be done at all without proper professional equipment. It doesn't add much to the overall cost of an engine rebuild either.
