The starter on my Sprint engined TR is gradually getting worse. When you turn the key more often than not the starter just spins but doesn't engage, it has always done it since I got the car. It was just occasionally and I could live with it but now it is happening more and more and taking longer to engage.

I'm going to change the starter, wondering is there any advantage to fitting a high torque version as they are a little dearer but not stupid amounts more. I'm not sure if mine has the heat shield fitted as is shown on the TR starter, is this something that helps prolong the starter?

before buying a new one?
have you tried cleaning the old one? including the terminals?
they can get full of clutch dust and cause this problem.
just use brake cleaner and when all is spotless use wd40 or like and then wipe any residue off as it will attract more dust.
i think you will find it will cure it

Had thought about cleaning it, but if it doesn't work means taking it back off again. Prefer remove/fit once, especially as will probably be doing it on my back outside.

Removal en refitting of the starter motor isn't that difficult. Should be a 15 minute job on the drive  
Just make sure you have all the correct tools for the job before you start.
(think of very long socket extension depending on exhaust manifold)
Also jacking up the car to access the lower of the three mounting bolts is recommended.
Removal and refitting the (original starter should be possible without removing the exhaust manifold.

But if you insist on buying a new one I'd say go for a modern hi-torque one.
As they are much smaller they are easier to fit.

Theo have you noticed a difference with fitting a HiTorque version?

I'm liking the size of them compared to the original one

Would you have a part number for the hi- torque starter

Rimmers are quoting same part number for the TR7 and the Sprint, yet WOSP who make Hi-Torque starters are quoting different numbers.

Depends which engine back plate you use. I have a TR7 back plate on my Sprint engine. So a TR7 starter.

And as you can see with this starter motor one mounting bolt is deleted.
The redundant mounting hole came in very handy for tying the starter's cable loom down  

Part number (from Robsport) GEU469U/R

Should have said earlier I went for a new Hi Torque starter, what a difference it has made to starting, it really throws the engine over. Best modification I've done to the car
