Current status, the car is broken down to chassis and is at the snadblaster getting cleaned and rust removed. Once I get it back I will get onto body work.
I am keeping the original steering, suspension and brakes. All is getting broken down, cleaned, new bushing, etc and rebuilt.
Then is comes to the engine. What do I put in this car. I have gone through so many ideas, 70's engine, period correct, Electric, 993 engine and some other crazy idea's that I won't mention.
I am leaning towards a 993 engine, the last of the air cooled. I am not afraid of a total engine rebuild.
Let me know your thoughts or ideas

I your other post you said you want a nice driver. Not a track car. "This will be a daily driver, no track days for now but I want it to perform well."
If it was me, it has everything to do with your budget.
Easiest: Replace your 914-6 motor (should be a 2.0) with a 2.7 that has had the case issues addressed. Should drop right in. Since you are getting a transmission as well, modifications to the car are minimal. A 1976 2.7 and earlier transmission will have the more fun 7:31 R&P. You will get a nice bump in power.
Next: A 3.0 SC motor. Still mostly a drop in replacement. You can keep it a CIS (nice for street) or go to carbs and the hassle associated with them.
A little more power? A 3.2 Motronic. You will need to do some modifications to the transmission. You may need suspension upgrades as well. Again, carbs are an option but as noted above, fuel injection is a pleasure for everyday driving.
I would not suggest a 3.6 as the modifications are even more extensive and is unlikely to enhance your street driving experience.
Other options (electrification, LS Swap etc), IMHO, are tickets to degrading what makes a 911 special.
