I doubled checked all versions of PET, and this is what it shows:
80-85 924 : 059.911.023.F, 0.6KW (CW rotation)
80-85 931 : 951.604.101.00, 1.1KW (CCW)
86-88 924S : 951.604.101.00, nothing listed for KW (CCW)
83-85.5 944 : 951.604.101.00, 1.1KW (CCW)
85.5-88 944/951 : 951.604.101.00, nothing listed for KW (CCW)
89- 944/951 : 951.604.101.00, 1.4KW (CCW)
89- M198 : 951.604.102.00, 1.7KW (CCW)
Non-tiptronic 968 : 944.604.104.00, 1.7KW
Tiptronic 968 : 944.604.103.00, 1.7KW

Based on these numbers, and my personal experience with the pre-89 944 platform, it appears to me that the CCW version of this starter will be good for any 2.0L 931, 2.5L 924S, and 944/951 variant up through the end of model year 1988, since they all share a common part number (951.604.101.00).

What I'm not sure about is the 89-onward application. It's confusing because it lists the same part number 951.604.101.00 but specifies a 1.4KW rating; also, I don't know what the M198 option is (automatic trans???), but it apparently had different part number and a higher rating. Also fascinating is that the 968 starters are both listed as 944 part numbers.

I know for a fact that the 924S and 944 starters are completely interchangeable with the 931 as I have done this multiple times. Since there is no distinction or separate part number for the 951 listed up through model year 1988, I think it's safe to assume these will work for the 951 as well.

I currently have an 86 NA starter on my 86 951. There were no issues that I can remember.

I received a reply regarding the heat resistance characteristics:

I'd like to know some specifics about this starter - where is it assembled, where are the components manufactured, whose bearings are they using and what is the warranty?

ideola

I'll add that to the list of questions.

Some questions to recently asked questions:

• The components are manufactured in Japan. The starters are then assembled here in the U.S.
• I am still trying to find out whose bearings are used.
• The warranty is 90 days (the supplier says "electrical components are tough to warrant". Their words, not mine). The supplier also offers complete rebuilds for $75, and they ONLY rebuild these units.
• The starters are not designed to spin faster but stronger – under a loaded condition. RPM of the starter is 4600rpm under a no loaded condition. All loads are different, but comparing this starter against the original (under duress of course), it would not slow down as much as the OE (original equipment) or stock starter.
• Amperage draw is 86 amps or less with a fully charged battery. If the battery is low or down, this starter will draw more amps, like any other starter does.

I'm intrigued, but I'd hate to be the guinea pig....
* Has anyone actually installed this on a 944/951?
* Has anyone run this for an extended period of time?

Also,
* Will one be made available that'll fit a manual 968 (yes, different starter -- also different for tip 968)
* What's the non-group buy rate from http://www.britishstarters.com/?

You already can. I have run Deka and Braille batteries in my car for the last couple years. In fact both winters the battery lived the whole winter with no charge, with more than enough power to crank the car in the spring.

I contacted British Starters, and their response was underwhelming. You're welcome to go that route if you'd like, no problem, but frankly, their pre-sales support was awful.

This is a new product for the 924/944/951 line, so consequently, I'm not aware of anyone currently running an IMI starter on one of the variants. However, there are plenty of references for the 911 crowd if you search, and IMI Hi-Torque has excellent penetration in other vehicles. Take a look at the Good Vibrations Racing website (and that's just one of the distributors).

As for the 968, if you can supply me with a core, I'll be happy to coordinate and see if we can leverage the group buy for pricing. I'm sure IMI won't mind expanding their range.

The roller bearings used are from KOYO, who incidentally, make OEM replacement wheel bearings for the 944 line. If I'm not mistaken, KOYO are one of the primary brands supplied to the 944 aftermarket by Paragon and others.

Sounds promising. My worry was that the motor/gears were manufactured and assembled in China. The one thing that does worry me is the 90 day warranty. Looking at other manufactures of GR starters, they range from no warranty (Tilton Engineering) to one year (Powermaster, CSR).

I'm on the fence about one for my 951. The other issues I have is the 4% PayPal surcharge - either build it into the cost of the product or offer alternative payment methods that don't incur the surcharge. If there are other payment methods, please post them. I'm also not overly excited with having to wait to see what the shipping charges and final discount will be either.

So would our cars sound like Hondas now when starting?

I like it. I'm a fan especially since I removed the heat shield there a while back.

I have a 87 951 - looks like it should fit, especially if it's smaller than the one for the NA.

Just curious - does the starter 'do' anything after it's gotten the engine started? Meaning, does it have any other effect on the engine or otherwise once the car is actually running?

I am interested.Can I send a check or do I have to set up a paypal account?I have never used paypal,but if I have to,I guess it is easy to set up.

ideola

Certified funds are an alternative payment method, and would not be subject to the paypal 4% fee. As for shipping, I don't know the individual weight + packaging + where everything will need to be shipped to. I can't possibly anticipate all of the locations people might want to have things shipped to, especially considering we have global interest over on the 924board. To keep things administratively manageable for myself, this is an approach that has worked very well in the past. Bear in mind, I'm not a commercial enterprise, and I don't make a dime from my time or effort to coordinate with the supplier, receive, repackage, and ship everything out. The group buy is an opportunity for everyone to benefit from the shared buying power of all. I don't mean to sound crass, but I need to keep things administratively simple.

As a practice, I only accept personal checks from people I've met in person, or with whom I've previously transacted business. Certified funds are fine, and would avoid the paypal fees. You don't need a paypal account to pay by paypal. The invoices I send out allow you to pay via their secure website using any standard credit card. The personal check policy is not a ding on anyone here at Rennlist, but again, I'm not a commercial enterprise, so I would end up personally eating the cost of any bad or bounced checks. I know Rennlisters would never do something like that on purpose ;-) but as they say, shiznit happens, and I'm not in a position to personal cover that liability.
