3.0 sc engine into a 77 911s questions..

schary · 07-01-2007, 10:53 PM

1.Any help out there for wiring this? engine is in the car.. the main connector is probably ok, but there are other connectors I'm not sure of.. Is there a resource for this?? Also, I have a msd 6al, which will further add drama..

2. The oil line at the rear of the sc engine (which has a full catalytic exhaust) doesnt seem to match to where the old hard line connected.. the car does have a front cooler.. Is there a hose that mounts to connect the two?..

Any help on any of this i would appreciate.. Its a special 3.0 with 964 cams
Thank you

I did this with a '75 body, and there are some wiring changes in the multi pin connector (at least for '75). I'm not sure if my info will help you, but I think I have a pin map. The fuel pump runs constantly on the '75, the '78 engine has the flap contact to shut it off which does not work on the '75. One thing I have not yey fully figured out is that the vacuum cutoff to the lower port of the WUR does not seem to work correctly with the '75 wiring. I had planned to post about this, but haven't yet.

I did not find any cookbook for these swaps during my effort a few years ago. I was surpised there wasn't any info.
