Bosch SR441X starter question

[andrew02]

Has anyone used a bosch sr441x starter for their 2002? I am looking for an upgraded starter and I know the bosch sr440x will work with no problems but I don't want to pay $200 for a new/remanufactured one. There is a store on ebay who sells remanufactured sr441x (cost about $100) who gets good feedback and says that the sr441x will work on the m10 block, but I just want to see if anyone has any experience with the sr441x starter. So, do they bolt right up with no problems? Any wiring or electrical problems?

Yes the SR441X starter from a late M30 motor like that in a E32 735i from '88 through '92 and an E34 535i from '89 through '92 WILL work perfectly fine in on a M10 motor.

The only thing that is of any issue is that the start signal wire for terminal 50 is a spade connector in the '02 while the SR441X starter uses round eyelet connectors. I feel the best solution is to find a spade connector adapter like that from a coil that has a 6mm post. That's what I use when converting to use one of these starters. I do not like molesting the original '02 wire harness to cut off the spade and crimp on an eyelet....

I actually prefer the SR441X starter to that from the E30 M3 S14 the SR440X.

SR441X has 1.7 KW

SR440X has 1.4 KW

Plus some great info found here on the 2002FAQ...

and as posted in another source. If you have a tii, don't hook up the black/red bypass wire. That upper terminal can cause the car to stall... at least with an electronic ignition.

I personally just replace the connectors, though totally understand if you have a very original car... but most wiring harness I've dealt with have been cut/chopped/hacked to some degree. Also, if you add a loop via a small extension, matching up the wiring diameter with stock could be an issue.

Reliability seems to be better with the loops, you stand almost no chance of bumping a wire or having one fall off with vibration.

I've installed both versions as well, super lightweight and worth every penny. Either will turn over a 10:1 compression motor with ease.

I wouldn't want to mess with the wire harness either, so where would I get an adapter that you described?

Thank you both for the help.

Beyond ordering one through a Wurth dealer I have gotten some for my personal stash from the ignition coils of various European cars in the junk yard.
