Nick,
Considering the history of the engine, your first ‘order’ should be to inventory the engine parts.
It is possible that you may have a collection of unrelated and worn/broken/defective parts, not a rebuildable engine.
The exercise will be a good learning experience.
IF you have a mostly complete (but not 100%) 911SC engine, you might consider buying another (same year) core engine that is complete and not disassembled.
This will allow you to select the best parts to build one complete engine and have a few saleable parts remaining.
If this engine turns out to be a collage of junk 2.7 & 3.0 parts, start from scratch with another engine.
Keep in mind that any rebuild is going to require some (expensive) new parts.
There is no getting around bearings, rings, rod hardware, chains, gaskets, etc.
There is also the ‘subcontract’ work; head reconditioning, crank & rod reconditioning, etc.
Your list:
“
Cost
No garage/tools
No experience
No car to go into (yet)"
Will need consideration.
Before you buy anything, start making lists – with costs.
The Bruce Anderson and Wayne Dempsey books are invaluable.
The Bentley on the 911SC will help.
You should get the PET CD listing
all Porsche parts.
You will need a situation where you can handle the disassembled engine(s) easily.
A set of 5’ metal shelves (3’x4’) on casters works well and fits in the corner of someone’s garage.
You can make a plastic cover for the shelf unit. Keep everything oiled to prevent corrosion.
A 911SC engine isn’t overly ‘tool intensive’.
Regular hand tools are all you need (something everyone should have).
The few ‘special’ tools can be borrowed.
Experience is what you are getting.
This forum is your best resource.
Start yourself a “Personal Workshop Manual” for the project.
Include threads, scans, photos, copies and everything else to write your own manual.
Car not necessary (yet).
This can be a fun and satisfying project.
Best,
Grady
