Noah is right, the FD is (cast) iron.
Repairing it would be no problem for a welding shop with the know-how.
Forget about JB Weld, unless you have a fire system in your car, and want to try it out.

Bump,
SOUK,
I forgot to mention my air plate rest position was correct based on the books I have.

Anybody got the Bosch number?

William,

Up to June of 1980 (3.0 @138KW) the Euro Fuel Distributor carried the Bosch Part #s:

New - 0438100031
Rebuilt - 0986438031

From July '80 through July '83 (3.0 @ 150KW):

New - 0438100097
Rebuilt - 0986438097

Rick, Thanks!
Where did you find the numbers? I've been digging for them for quite a while. Most of the rebuilt numbers I've seen are FD___X.
Do you know a source for parts to rebuild the FD?
Thanks again!

Rick would your source indicate if these were used on any other vehicle?
Like an application guide.
Mine would need the later: It's a 83 ROW.
The Mixture Control Unit has the tag with :0438 120 143 do you have numbers for these? does this match the porsche part number 911 110 975 00?

William,

I called Bosch.

I have a personality disorder known as Need-to have-access-to-as-much-information-as-possible (AKA Information whore). It comes from me pretending to be an inventor. Sourcing parts or services is a hobby of mine.

There is a "Vehicle Part Finder" on the BoschUSA site that has references to US parts but not Euro. So I called for the part # and wrote a request for a link to a Euro parts finder. Hopefully they'll have one.

BTW, the Bosch tech (Jim) who called me back was a super nice guy...only too happy too help. He mentioned that it may be easier to get a rebuilt unit here in the US.

US Bosch Parts Finder: http://www.boschusa.com/AutoParts/PartFinder/partfinder.asp

Number I called to request a call back from a tech: Bosch Customer Service:
888-715-3616
(Monday thru Friday 8:00 am to 5:00 pm CST;
for U.S.)

Thanks!
I'll be noodling arround on that site for a while!
I wonder if there is a vehicle application cross reference or maybe this was a one of a kind?

Rebuilt ROW FD in place finally also installed a new Control Pressure regulator. What a difference! The car never pulled like this before!

I am still tuning but it seems I now have the opposite problem. It's lean at idle and rich everywhere else. The system pressure and control pressure were just about 1-2 psi high (parts out of the box and installed.) I might take one shim out of the system pressure regulator.

My ignition may have a part to play in this since the car has the later ignition distributer with the vacuum retard that was not present with the ROW cars. This I understand was for emissions on the K-lambda cars.
Anyone know how I should adjuat the timing on this bastardized setup?
The specs for this distributer on the 930/16 (USA) engine is 5deg BTDC with lines disconnected. Checking for 19-15BTDC @6000
The ROW specifications are 25deg BTDC @4000 checking at (not above 25deg) BTDC @ 6000 (Hoses off)

I've seen a post that quoted JW as stating 35deg BTDC @ 6000 with everything connected. Using 3.5% CO at idle.
I assume this is a US spec recommendation.
The ROW 930/10 CO% spec is 1-2% which makes sence since I'm way too lean at idle with the ignition retarded.

Should I then leave the vacuum retard disconnected?
I just got an advance timing light for X-mass. Can't wait to use it.

I need some help with theory here:
Was the ignition retarded on the 81-83 US cars to help lower the emissions at idle so the gasses could be handled by the 3-way CAT?

Was the ignition retarded to help it start and warm up faster?

Retard was not used on my ROW K-basic version CIS so what's it do for me? Probably makes things worse.
Are there other differences in the ignition distributer?

Ditto Pari, Did you get your tail painted?
I'll be home off and on for a few days if you need anything.

Will,

Great to hear you're almost there. One of the CIS experts will chime in soon....

Bill, I installed my new shift knob. Getting the factory knob and crush ring off was a PITA. I did find somewhere to paint my carrera tail. My friend knows someone who's family specializes in painting Bimmers. I have seen their work, and it is exceptional. Plus since my friend knows them, they probably won't charge me more than $100-200. The shop is in NoVA.

Will they do a whole car?
I'm starting to look since that's the next on my list.

William, could you tell me where you were able to purchase a euro fuel distributor? My car is in the same situation as yours (U.S. spec fuel distributor on it now) and I want to put the euro FD back on it (it's an '83 SC by the way).

thanks,

amir
