Good progress this weekend on plumbing the EGR and vacuum controls on the engine. Rob und Wilhelm helped with correctly linking up each section of the vacuum controls. Tonight finally was able to install some fuel lines. Tom at 928 Int'l has been a massive help in sourcing the correct fuel pumps and fittings.
Here are a few progress photos.
Looking good!
Need to install this bracket in front of the accumulator. Mounts to the 2 isolator studs.
It's function is the 3rd mounting point for the splash-guard.

The most difficult part to source on this entire project has been the Alternator. I finally located an original Marchal unit that uses the first stamped steel cooling duct. I found one on ebay. The seller had a Marchal unit for a Volvo - I emailed him on the off chance he would have an early 928 unit. Score! It is part no. 928 603 113 03 (Marchal Alternator Assy) or Marchal part no. 71236002. I was in luck, this unit arrived rebuilt and ready to install. 928 Int'l had the steel cooling duct. Lots of dry fitting the adjustment mechanism and wiring. 6th time was a charm. If anyone needs a fully fully rebuilt Paris Rhone Alternator for an early 928 contact me I have one for sale. PM please.
Hello AD0911,
Following up on your comments regarding the rear shock absorbers fitted to the transaxle case. I've finally had a chance to finish the fabrication on these parts can report the following progress.....

Amazing job! What surprised me was the fact that there are different shock absorbers and brackets while they were just deleted later on
For the CIS injection hard lines. A key tip I learned from the Minerva restoration was the CAD plating on the hard lines. Some foreign material accumulated in the lines and clogged the injectors. Thank you to William for alerting me to this failure mode. After having my lines replated I wanted to do a thorough cleaning of the bore.
I recently started using a new cleaning process on another restoration project- vapor honing. Basically this is fine abrasive media in a water stream. It is very gentle on surfaces and gets all the foreign material off. Here is pic of a case set before and after.
As an experiment I took up all the hard lines off of my CIS system and we found a way to mate the end of the line to the blast nozzle.
Here is the result, a beautiful stream of water with media cleaning out each line. Followed by a fresh water rinse, followed by brake cleaner blast, followed by compressed air.
The service costs $10 per line and Steve is extremely enthusiastic and pleasant to work with. He is located in Orange, Calif. The business name is Parts reborn. check out: PartsReborn.com he has some impressive images of the before and after with this process.
Quite late to this thread, but in my opinion the work 'mit wasser' , Rob and William are doing is just phenomenal. This is going to be a spectacular 'old bugger' when it is complete. My sincere compliments.
For those who may be unaware - 'mit wasser' is extremely well known in the BMW 3.0 CS community (actually BMW e9), as he has a BEAUTIFUL rendition of that car. If you see a P21s advertisement for their Auto Care Products in one of the automobile magazine ads showing a beautiful blue BMW 3.0CS with white interior - that is 'mit wasser' and his car.. I'm sure this 928 will be every bit as spectacular as the BMW when complete.
This thread is titled engine and front suspension. I'm now joining it with the earlier thread on the rear suspension. The theme on that thread was showing respect to the original engineering efforts that the Porsche engineers went through in developing what became the Weissach rear suspension. And what an effort. Here are the (near) finished images of the rear suspension. Ready for brake fluid this weekend.
I think I discovered why these small vibration damper shocks were never fitted to the production cars..... 'cause they are a complete PITA to fit into position and tighten. (center of image)
I'll add one more comment - it is just sickening to look at these pictures and detail, then reflect on what I've previously done with 928's and my current Bimmers! Really embarrassing as well. Talent is a wonderful thing to have.
Front suspension finished earlier this week. Brakes for that last moment before they are filthy. Plating is Gold Cad. Karp's Brake Service in Upland Calif. knows how to properly restore calipers.
