Thanks again for setting up everything!

Doh! I wanted one of these and lost track of the thread...

Will someone that gets one post back on the install (with pics PLZ!) and experience on a late 951?

Where can I buy one of these now?

I've received the invoicing from IMI, so payment will be going out shortly. They advised me they had enough parts on hand for 28 units, so I'm optimistic that the starters will be shipped from Cali to MI sometime next week. Stay tuned!

There is an outside chance the starters will be delivered to me by end of this week. Regardless, if all goes according to plan, I hope to begin shipping next week.

Hmmmm..... 8) 8) 8) 8) 8)


Stock starter on a 931...


IMI-155 Gear Reduction starter installed on a 944


The good news is that the IMI unit bolts up perfectly, and you can see there is TONS more clearance on the exhaust side, so those of you who were asking about clearance with larger exhaust pipes, I don't believe you will have any issues whatsoever.

The clearance between the end of the motor on the IMI unit and the side of the torque tunnel where it begins narrowing is very very close...probably about as close as the clearance between the clutch slave cylinder and the narrowing portion of the torque tunnel, not more than a mm or two. If you have worn motor mounts or excess engine vibration, you may want to consider re-indexing the motor by one position. In the following photo, you can see the four additional indexing mount points on the flange, which allow you to rotate the starter by a few degrees. Simply remove the two 4mm allen head screws, rotate the flange, and reinsert the allen head screws. In so doing, you will have plenty of clearance with the chassis wall, but the ear on the end of the starter may be a bit lower. However, it does not appear to me that it will create a ground clearance issue, as the exhaust pipe is even lower in that vicinity. I'll leave it to each individual to determine the best setup for their car. I have confirmed with IMI that reindexing the flange does NOT void the warranty, so you should feel free to do so if it makes you happy.


For the 924 NA guys with the CW motors, I don't have a way to test fitment. Hopefully, it will bolt right up, but if there are any clearance issues, you should be able to address it by reindexing as described above.

I am going to the post office shortly. I need to pick up 24 medium flat rate boxes. I will be working on this over the weekend, so look for the tracking number notifications from paypal, and expect your starters to go out via USPS early next week.

What is the difference between the IMI155 and IMI155CW that I see on the boxes?

Shipping Update
OK, boys, all the starters are boxed up, labeled, and ready to go out. These are all going USPS Priority Mail, so 2-3 day service in the US, and 6-10 day service for international recipients. I will be dropping everything off tomorrow afternoon at the Post Office on my way home from work. Hopefully, PayPal is functioning correctly and you're all getting your email notifications with tracking numbers...but the packages should arrive before they'll even be trackable :P

Installation Notes
One minor note for installation: the small terminal is not a post as in the stock configuration, it is a male spade terminal, so you will need to modify your small wire on your stock harness to change the ring terminal to a female spade terminal. Also, when installing, you may want to attach the wiring harness first, as the terminals will be up top and more difficult to reach once the starter is bolted in place. Otherwise, on my 931 and 944, the starter bolted up with the stock bolts no problems.
