I am considering putting a 5.6 liter engine & 4 speed trans into an earlier chassis (107) and have several questions:

Could someone please tell me what year MBZ went to: 1) The Electrohydraulic type CIS injection versus the ‘regular’ CIS w/ frequency valve? 2) The electronic ignition map system instead of the mechanical advance type?

Is it likely that a fuel distributor from a (euro spec) 5.0 engine (OR even one from a US spec 450 with lambda) will work on a 5.6,(with the proper warm up regulator, of course) or is it imperative to use the EHA type CIS injection? IF I need to use the EHA, is the controller a separate unit that I can wire in, or is it integrated with additional functions other than fuel mixture control?

Much MUCH appreciation for your input :)

The onset of KE-Jet on v8s came in 1986 for US models (probably 85 in some euros).

The fuel distributors are fairly universal, take for example the fuel dist for a 79 450 and a 6.9 are the same. What is different is the airflow meter and control circuits.

A K-Jet w/lambda or KE distributor will need the control unit and harness.
