Pre-Engaged High Torque Starter
Turbo Mini Forums

I'm trying to make a pre-engaged high torque starter.



Started with Toyota MR2 and Metro starters. Machined the ends to fit together which will be welded together.



Going to weld the pinion to the motor shaft unless anyone can suggest an alternative method.

what does the pinion from the MR2 starter look like?

would there be enough meat to tke the outside off the mr2 pinion so it slides into the metro one and weld those together?

Paul what car is that off??

I fancy having a crack at converting one of these!

Time for a silly question....

What is the appeal of these ???

Is it just that they are more compact (solenoid on top instead of part way around the front, or fully in front if it's a Metro one) ???

The high torque should only be an advantage on a highly tuned (ie, very high CR) NA engine. I've never had any problems with the standard starters on normal CRs so the normal starters should laugh at a turbo engine with its low CR.

So what am I missing ???

Rod, I thought the same thing a while back when the Twins were selling them, the real advantages are not from the increased torque but from being smaller, lighter & apparently they draw less current and are more reliable.

It's off a Toyota MR2, Mk1, I think.

The only reason for us using one is that the solenoid is on top making more room for for the front mounted rad and intercooler.

these style starters are used in allmost all mr2's with the 3sgte engine and some subaru imprezzas aswell. if i mind when im in work monday i'll have a hunt see if i can find a subaru one and take a pic of the drive wheel for you, incas e its the same as the mini.

Thanks all, I just wanted to be sure it wasn't the high torque - I couldn't get my head around that.....

I don't think that they are any lighter either. With one in each hand I can't tell the difference.

The large part of the starter, in line with the pinion, is actually the solenoid. The motor is the small part to the top and is geared something like 4:1.

Paul, The ones we have been modifying are no doubt the same as the one you have. The pinion on the starter works with the old 107 tooth ring gear, but not the verto 127 tooth ring gear. So you should not need to change the pinion. We have never seen a starter that matches the 127 ring gear and my mate who makes the starters has seen lots of different variants.

A man without a project is like a like a woman without a shopping list.

I'm using a verto flywheel with the 127 tooth ring gear so I need the smaller pinion from the Metro starter.

It does look like the standard pinion will fit the pre-verto ring gear.

Hi Ben

I've been looking for one of these. Can you still get hold of them.

Perfect to replace my old inertia starter which is getting a bit old.

I drill holes in everything..!

How are you getting along with this mate??

Ive just bought one for 99p!

Paul. Please make two. I need one for a Verto ring gear myself

V, my current rates are £60 an hour - is that OK?

Depends on how long it takes I can see that they are readily available for approx £155 different places. I guess I have to bite the bullet.

Seriously, this has taken an age to do so far and I still do not know if it will work.

Machining back both the housings to mate together with very little to grip in the chuck means lots of very small cuts.

I think that they are available at £140 from Lynx ??

Who was the person who stumped up the £120 for the pre engaged one at that stall one up from the SC stand. There is some money to be made making cheap High torque pre engaged starters

Dunno but i got a Calver belt drive off Antman for £5! Result!!!

Just got 1 of these this morn, its exactly the same as urs bud. ive noticed ours are a little different from bens, how did you machine the starter?
