yes the 3.0 will fit . the best answer is to drop a 123 bluetooth distributor in the engine .
It is very important to be able to set the timing advance and retard as the boost comes in If you do not manage the boost it will work but not up to it's potential, idle will be tough as well Ian

No, I think they turn different directions, 77 clockwise, 79 counter clockwise. ??

 The 3.0 turbo engine as well as the 3.0 Carrera uses the 2.7L crankshaft which spins the distributor CLOCKWISE. The 911SC 3.0 turns the distributor COUNTER-CLOCKWISE. You unfortunately can't use this distro in your buddies 77 turbo 3.0 motor.

You need to change or convert the SC CCW distributor drive gear to CW rotation. Tony |

Thanks all! If a 3.0 spins backwards, wouldn’t that affect the advance mechanism?

Would you need to change the gear on the crankshaft to match the distributor drive gear cw rotation?
