Dear TSSC members, I'm new to the club, and new to forums for that matter, so interested to see how this works. I bought a lovely 1973 GT6 MK3 in the summer. Previous owner lavished much love and attention to restoring the body work, but other factors meant he needed to sell before getting stuck into the inner workings. I've had a great couple of months using it, but I think time has come for improvements. Whilst it makes a lovely noise, depressing the accelerator produces more noise, but no discernible performance! Max speed is 80mph at 5000RPM. Interestingly, a rolling road test at CCK Historic in Sussex recorded good oil pressure and good compression, but only 61BHP at back wheels. Another factor is engine temperature gauge is off the scale (hot side) within 3 minutes of driving normally, but a laser heat recorder fired at different parts of the engine indicate its actually running at correct temperature. I have changed the temperature sender unit, but same result. Anyway, I am getting off subject here. The overdrive has recently failed, and speaking to people 'in-the-know' it sounds as if the Conical clutch is worn out. Symptons are strange rev fluctuations in gears 2-4 (regardless of position of switch, which is now always 'out'), and the car now won't reverse. That was a bit awkward in the Waitrose car park when it first happened! I have therefore taken the decision to have all three items reconditioned at the same time over the coming few months. Not only that, but I want my engine improved to the best available road-going performance (this one isn't for racing). I have chatted with a few 'suppliers' including CCK in Sussex, Southern Triumph in Bournemouth, Jigsaw Racing in Corby, Slark Race Engineering in Amesbury and the TSSC themselves. The general consensus is that Gearbox and O/D is a fairly simple overhaul, with no special options. Engine however can have various bells and whistles, all at cost. It seems a 'stage 2' overhaul with the stromburgs to be replaced with SU (from Dolomite, or machined to fit), would create the best outcome at sensible cost (a relative term, but I imagine this will all cost a bit North of £5-6K?). I note talk of Weber Carbs, but they are apparently excessive for these cars. I Also note talk of putting a TR6 engine in the GT6 (and now would be the time, if ever), but no significant advantages over getting my own 2.0 litre engine running well. I am leaning towards Jigsaw for all this, but all suppliers are knowledgeable, and seem to offer a slightly different angle and opinion on the subject. The purpose of this lengthy post, is to see if anyone else has jumped through these hoops, in particular with Jigsaw, and have any thoughts! Thank you.
