Starter options for 944/85.1 (early) starter models

Recommended Posts

TLDR: I'd like to replace my starter. Does anyone still stock the large diameter starters?


After getting weaker and weaker and giving me a few push starts, the starter on my 1985.1 944NA has now finally given out. It is a large diameter Bosch starter with the markings 047 911 023A.


From what I've read, there have historically between two starter options that fit, an earlier large diameter starter and a later model smaller diameter starter.  The later model smaller diameter starters will fit (95160410100), but its increased EMI may cause issues with speed/reference sensors and the replacement bracket to fix this is $125+.  In 2012, people were enjoying a third option in Ideola starters, which seems to have gone out of business.  


However, the current part number seems to return small diameter starters EG, https://www.fcpeuro.com/Porsche-parts/944/?year=1985&m=20&e=803&t=6&b=9&d=&v=12&keywords=starter




If I want to use the newer smaller diameter starter, the updated sender sleeve is $35 (https://parts.porschelivermore.com/oem-parts/porsche-sender-sleeve-94410132000) and it also needs a new bracket that is more expensive.


Does anyone still stock the larger diameter starters at an affordable price?

You can have the current starter overhauled at a Bosch center, spare parts are still availlable. This is a cheaper solution and remains original, collectors of classic cars do this all of the time.

Followup: I replaced this with a newer SR39X small diameter starter, which works.  I did discover after this that my original Bosch starter is actually good (both car batteries I tested it with were not).  The difference between a direct drive (original) and a geared (small diameter) starter is significant.  I like the feel and sound of the direct drive starter and I'm might swap it back in.
