i have a 2000 that i am looking to put an 03/04 3.6 996 engine in. requires conversion to 7.8 dme which isn't that difficult - change some pins, run some additional variocam wires. the problem is that the 7.8 also requires conversion to canbus - gotta run a bunch of canbus wires, update the gauge cluster, update the hvac controller, and update the abs pump with means new wheel speed sensors and fourth brake line to the back. it is my winter project.
with all the people popping engines recently, however, thinking about keeping my original engine as a spare, and trying to sort out how to easily swap in an engine with the early variocam system into a car wired and programmed for the later system. thought about keeping the later system in and trying to fool the sensors and controllers, but seems a lot of work. then read on pelican that the 01/02 cars had canbus but still ran the 7.2 dme. if so, i can leave the canbus system in and just swap my 7.2 dme back in with the old engine (with a reprogram to an 01/02 tune and some pin changes).
