We know the EZ69 ign. unit is discontinued. Freq. valve discontinued.
I checked our Brake booster Pump and it says This part is no longer available for 964 and 993 models.
The Brake booster pump is $1900 used Online. I assume Singer is not using the Booster Pumps?
There should be hundreds available. I could be wrong as i don't study the parts on their cars.
I was interested in selling mine.

Any thoughts?

There's some info here on using a Jaguar part (available for ~$220) to replace the motor in the brake booster pump

I don't think that Singer is using many C4s or Turbos as donors so there probably aren't as many out there as you might hope.

I would try to rebuild it. I have one on my shelf and a spare switch but I have 4 cars that need the parts just in case.

Not much help but Porsche still makes the 928 version. I don't know if they are interchangeable but I know my ABS pump on one of my cars is the 928 part number and others 964.


Not that it helps much as they are $3,261.30 discounted from Porsche. My GTS pump it actuates the PSD which is essentially the LSD system for the C4.
Part Number 92831590601

There are companies that rebuild them for $1800.00

Scott, I took mine apart around 5-6 years ago and rebuilt it myself. I think that I documented it with photos. It is a simple/dumb system, and there was nothing inside the system I could not reverse engineer and resource. It took me 2 months as I was not in a rush and wanted it perfect.
