1979 3.0L engine to 1983 911SC Targa
 

Hello everyone:

I have a 1983 911SC Targa, so I thought I would ask this forum a technical question regarding "our" model.

Can you mate a 1979 3.0L 911 engine with a 1983 911SC Targa car? Are there any issues, or rather is there a problem mating the transmission from the 83 to the 79 engine? I have noticed that 1978/1979 flywheel and pilot bearing part numbers are different. Is a 915 transmission from a 1979 911SC similar to a 1983 911SC transmission?

What I have in mind is this, I have a 1979 911 engine that I am thinking about running in my car (1983 911SC Targa) while I remove and rebuild my original engine . Will this work? Or, should I find a 1979 911SC transmission to mate with the 1979 engine and then install as a complete package?

Is this possible? How would some of you go about proceeding with this project?

Thanks in advance for your help with this, guys!

bolts right in, complete. you just wouldn't be able to use the car's oxygen sensor system, which is a good thing.

Thank you for helping with this question. That is wonderful news.

I will drop by to say "hello" in the Spring after the roads clear-up from all this snow we are having. I may have some cylinder heads that need working on.

cheers.:)

You may have a problem if your alternator for the 79 has not been changed to an internally regulated one.

Hey, buddy I did not think about that. You are correct and there WAS a change to the alternators with the voltage regulator being placed within the alternator instead of mounted on the left-side of the engine compartment.

What would you recommend ?

Thanks,:)

the 79 wire harness will have a regulator plug on it, so get a regulator and mount it on the electrical panel. i believe the 14 pin plug to the panel still has the wires in the correct order, ie: blue to blue, black to black, etc. wouldn't hurt to check.
