ENGINE SWAP: "MC" Turbo wiring questions
I am looking to put a 162hp "MC" turbo engine into a Volkswagen Westphalia
camper. I have swapped other CIS based engines into Vanagons and Rabbits
before but I have a few questions about the wiring of the MC:
OXY CONTROL UNIT
PIN 8 BL/BK - This goes to the display computer - I assume I can leave this
PIN 14 G/V - Is the connection to the AC Control Head - I assume I can
leave this unconnected?
PIN 17 Y/BL - This goes to the display computer - I assume I can leave this
PIN 31 Y - This looks like it receives power when the fuel pump is on,
why the knock sensor light attached to it?
PIN 32 R/Y - This goes to lamp control unit. I assume this is telling the
control unit if the engine is on or not - I assume I can leave this
How important is the 3-stage radiator fan relay stuff? I understand the
need to circulate coolant through the turbo when the hot engine is off, but
the Vanagon has a dumb dual temp "fast and faster" speed rad fan. Is
connecting the Audi rad fan relay to the turbo coolant pump enough or must
I interface it to the Vanagon's rad fan as well?
Besides the idle stabilizer and other CIS related components, what are the
other things that I *must have* in order to make this work to it's fullest
potential in a Vanagon? I intend to find a 5000 Turbo with a dead
automatic transmission as a donar car, so I will more that likely have a
complete car to play with.
While I am at it I want to make the MC perform better, what should I do to
it during the swap?
Thanks in advance!
