CIS feul distributor
Does anyone know if there is a difference between the aluminum bodied vs the cast iron bodied fuel distributors I have both here ready for rebuild just wondering if I should bother with the aluminum one?
thanks

yes the aluminum fuel distibutor came off MB i have seen a picture of a 928 with one being used so i'm assuming its the same just looking for conformation before i spend time working on it

The biggest differences between the MB fuel distributor and the 928 are (1) the individual adjustments for injector pressures and (2) the gasket between the two halves is rubber rather than stainless steel. They should be a good replacement for ours but the new and rebuilt prices are much higher.

Can the gasket from the MB FD be retrofitted to the Porsche FD?
Are the spring/caps found in the individual chambers on the Porsche FD not used on the MB as you have the individual adjustments?

The MB unit still has the springs and caps. That is what deformed the rubber gasket pictured (second picture) on ebay.

450, 500. Euro one is the one to get if you can. They run about $90-100 and the cost to rebuild isn't any more than the cast iron one. They are easily cranked up by adjusted they flow circuitry - hence no magic to it. Talk to Larry at CISFlowTech in Louisiana and he will take care of you. The cost for a total rebuild of the block, WUR and injectors is about $800+_ alum or iron.

Paul....to me, the rebuild seemed easy (cast one)... But I have torn it down 4 times now, and my car still does not run....
If you have not done it before, be meticulous, and watch out for the little washers.

Why am I doing this? Rebuilding a fuel distributor
Just the lapped surfaces alone require a great deal of care and attention. Using the wrong materials will cause you issue as well. And finally there is just the experience factor that comes from having done it _right_ many times.
I'd say that if you have taken the time to re-do your work four times and still have not met with success, you have more than overspent on your CIS system. Send it to a pro and get it done and have fun running the car. As I said I spent $800 for 16 injectors to be ultrasonic cleaned and flow tested; rebuild my WUR and rebuild my fuel distributor. I don't know about you but my time professionally is worth $200 / hour. So I figure I saved $800

Oh yeah, forgot to mention. The 928 fuel distributor flows more stock than the MB Bosch 0.438.100.111 version. And there is no physical modification that needs to be made to the block to crank it up. What I mean is there is no machine work necessary to the flow slits. You can change the characteristics by changing the output nipples and fuel return and other non-invasive tweaks.
I just acquired a euro 0.438.100.111 that I am going to have rebuilt and play around with on my M28.22 and see what I can squeeze out of her. I will post results at some point over the summer.
