Currently have a problem with the starter motor getting "cooked" when using the Sprint in competition and then refusing to start. It's fine when cold. I want to get a high torque starter. It seems some manufacturers list the starter for both a Sprint and a TR7 while others have separate part numbers. Can anyone advise a good supplier and the correct part number - don't want to get it to Australia and then fine it is wrong!
Many thanks

I am using this one in my TR7 fitted with a Sprint engine so hope that doesn't confuse things even more. Its a Powerlite RAC406. Seems to work pretty good but I did fit a wrap around heat shield because its close to the tubular exhaust manifold.

I have used power lite on other cars and the quality is superb. They are British made and service is second to none. When I bought my last one I spoke to a very helpful guy called George Shackleton - a relative of the great explorer Ernest. I couldn't recommend them more highly.

It's personal experience like yours that is invaluable when choosing suppliers and parts. Thanks for sharing.

For what's it worth nowaday's my comment is that these starters are bugger. For a period of nine years i drove about 50.000km a year daily with a dolomite and had three fails of these within two years. I did want just as you more reliability but it was the opposite. The denso starters are very good but the problem is that when they are modified to the hi torque power blah suitable for Triumph the contacts and the coil are replaced by boogie woogie chinese repair parts and that causes the fails. As all parts it has to be as cheap as possible. I think when they leave the 20 year old original toyota relay on it and only fit the adapter plate and the gear wheel you have a better starter than what they make of it now. When you drive 300km a year with your dolomite it will be a perfect replacement but for daily or motorsport it is as unreliable or even worse than the original.

For many years i use and more in Holland a modified modern bosch starter what is a slightly modified new original bosch what does last normally for 30 years and 500.000km. I do not know the type but it is 1,7kw as to the original lucas of 0,7kw. A friend of min does work at a starter motor company so can compare and switch parts and he does make them for me. They are twice as expensive as the average high torque but do not fail.

Thanks Jeroen,
that is very helpful to me.

I have been thinking about fitting a Hi-torque starter for a while now because I have had two reconditioned Lucas starters that only lasted for a short time.
Currently I am using a new old stock Lucas starter but before fitting it, took the precautions of wrapping the exhaust manifold and also fitting a Lucas solenoid heat shield.

I'm looking a fitting on of these, I see only one small wire going to the solenoid, what happens to the one with the small spade connector?

You fit them both to the high torque starter spade terminal and remove the white yellow from the ignition coil. The white yellow has to activate a relay now what is going to deliver the bypass high start voltage for your ignition coil.

Thanks for that, do I need to connect a relay up next to the coil
Could I fit an ordinary 12v coil with an ignition controlled feed

You can use any 12v relay. Ignition feed on 30. 87 to coil+, 86 to starter wire white/yellow and 85 ground.
