Also i later tests last night there is more of a grinding noise happening from the starter, so I have alerted Roger. My suspicion is that replacing with a functioning starter will bring the battery performance back to more expected levels.
So the starter sounded like it was dying when I tried it this am and the battery was hooked up to the trickle charger, so I SWORE it was the starter, however I noticed my charger had an error code (which happens if I plug it in without giving it enough time to reset), so I suspect it wasn't charging the car. I was able to run jumpers from my DD battery to the 928 jump post to give it some juice and the starter sounded better. Now I am suspecting a poor performing battery due to low use and cold. I can have checked at some point to see if I should get a new one.
However this is not the reason for the no-start issue, so I can keep trickle charging the weak battery for testing purposes for now.
Probably this closes out this thread though since it was focused on the starter itself.
Not really clear, or I just am missing this:
Is your 89S4 an automatic or a manual version?
Slow, laborious cranking, on the cars with automatic transmissions, can be caused by excessive preload on the flywheel flex plate, leading to thrust bearing failure.
This is not an issue with the manual transmission models.....

Excellent question and point. In this case, this car has a manual transmission.

Yes, I see that, here.
Last night, on my phone, your list of pieces didn't show up.
Sorry.
BTW.....the last iteration of aftermarket starter motors from IMI (IMI-101-928) don't sound like you are cranking over a Toyota. They sound really nice.
And unlike the latest rebuilts from Bosch, they actually fit....and you can "clock" them so the mass of the starter is directly in the middle of the oil pan....and not off towards the left side.
If you really want a Bosch replacement, call 928 International.
Mark is now sending out original starters and having them rebuilt, instead of providing the "rebuilt" from Bosch, which doesn't fit worth a darn.
I've used several of Mark's rebuilds and they work great!

100% agree with Greg on this one. My car starts with the sound of a 928, just turns over 50% faster than most OEM or Bosch starters with no lazy cranking at all.

My need a startup sound clip to prove your point Love to hear it!
I'd also check all the starter connections themselves including the primary ground up there. Might want to take those apart, treat with Deoxit and make sure you have good, clean connections. If a battery is 5 years old and the car isn't driven at least once or twice a week and not kept on a maintainer, the batter is very suspect..
If you do end up needing to replace the starter, the hi-torque versions I have in both my 928 and 914 are sensational. When my 928 turns over and starts, it doesn't even sound like a 928 when it's cranking.
Please fix the underside of your car. Far too clean and how are we supposed to know what is wrong if there are no oil spots or leaks to point you to your obvious problems!!! I mean really. Who let's their 928 get like this!
