Three times in a row success. You do indeed know how. ;)

So, "heat soak" goes away when the engine cools down a bit, right? I think my starter has had this issue once or twice. I got a new High Torque on the shelf ready to go.

Yep, usually 30 to 40 minutes later it will spin just fine. If you can wiggle under the car, and squirt water on the starter it will cool down faster. It is really uncomfortable under the back of a 911 with HOT exhaust and heat exchangers so not recommended. The car will easily push start as well if you have someone to push you or a handy hill. BTDT.

I'd go to autozone and snag one for about $100 with a lifetime warranty.

You will get lots of practice swapping them.

Most all of them are "rebuilt" with the cheapest parts possible, and are near junk quality. Have a local rebuild shop rebuild your current starter with high qualiry not Chinesium bearings, and good lube will be better, but not a real cure for the HOT conditions and a long day of driving.

I did all that, and still had the heat soak issue. The high torque starter simply cured the issue.

If you have a 915 the starter swap is not too bad, so the autozone starter is not the worst option if you don't do long drives. With a G-50 transmission the starter swap is a bigger pain to do, and you will not want to do that regularly.

Your car, you money, your labor, your choice. Not my problem.

^^^Did you try cleaning the electrics and installing a beefier battery ? That way, you might avoid having your car sound like a Toyota.

Story from November 2020: The original Bosch starter on my 87 started acting up, and before it died it destroyed my flywheel, so had to drop the engine, new flywheel, new starter, and the whole thing.

I went with the refurbished Borsch starter, because, they wanna keep things original right? We fixed things up, and I started a roadmap to California as everything had been replaced. About halfway through Oregon the Borsch starter simply dies, and I'm stuck in the mountains. Getting the car towed to a local shop. Confirms that it's the starter, and I'm they are ordering a new starter to install. I'm waiting a few days for the parts to arrive, and another Borsch starter is installed. The car finally works, and I can continue the trip.

Fast forward one month, and guess what? The second refurbished Borsch starter dies with the same problem, and now the vendor confirms that they have quality problems with them.

Conclusion: I went with the high-torque starter after trying two refurbished Borsch starters, and haven't looked back. I would recommend you to do the same.

You meant the starter ring.

What other loads do you have on the battery and electrical system ?
