Latest Porsche Acquisition - '81 931
Brought her home on a trailer today. Body is in really nice shape, car has been parked in a garage under a car cover for the past seven years - timing belt broke, PO had the head work completed, bought all the necessary parts and then life happened, didn't get around to putting it back together - car was advertised on Craigslist for $800 - I didn't pay that for it - have a look

Here are a couple of photos of the engine:
Overall shot of engine compartment before bringing the car home
You can see the smile on number 4 where the piston crashed into the valve, looks like it may have been the only valve that made contact. PO had the head work done, but did not provide any receipts for the work - I may take the head to the local machine shop to have them check it out.
The rest of the cylinders don't look bad
There is a broken bolt in the turbo flange, I will need to remove the turbo to get good access to remove
Here's a shot of the Air Flow Meter, look clean, moves easily, hopefully it will be fine
This morning I cleaned out the cylinders and then wiped them down with grease, the car will be sitting under a cover outside for the winter and I don't want the cylinder walls or rings to rust.
When I get ready to put it back together I will have to clean up the rust that has formed on the top of the block, I will probably use a roloc disk on my die grinder, I don't think this will be much of an issue.

Nice find ! Congratulations !
How silly would one be to sell a car like this for literally nothing.
A car like that(euro version) and working will fetch $7k in Europe easy.
Car looks solid, the only thing you need to sort out is that surface rust on the engine block.
Don't install the head over the block looking like this.

My intention was to use a roloc on my air grinder to clean it up the block surface but someone else made the suggestion to use a few light strokes with a mill file followed with an oiled India stone to clean it up/keep it flat.
A little history on the car:
PO owned the car since 1987 and has had it garaged the whole time he has owned it. The car was painted approximately 8 years ago - at the same time the turbo was replaced (the old one was leaking oil and causing smoke in the exhaust), about 7 years ago the TB broke. The owner started the repair, had the head repaired at the machine shop, bought a head gasket set, a brand new cam and cam followers, then life happened. The car has sat covered in a garage for the past 7 years, I know I will have to drain the fuel and go through the fuel system, but I could not pass up this opportunity. I am very excited to get started on the repairs. Unfortunately I will have shoulder surgery in a couple of weeks so this project will have to wait until late spring/early summer before I will be able to get a start.

What a cool car! I loved my 931, good luck in getting it running! 81 was a good year for that car, there are a few small things you can do to really turn that thing into a rocket.

Great buy! iirc the valves are expensive for the 931 so it's fortunate that the head was done beforehand. I did a timing belt on one a few years ago and it was really easy to do, much easier than a 944. Anyone know why they went to an interference engine on the 931 when the 924 was non-interference? Assuming that 931 had a lower cr than the 924 so that seems backwards to me.

It was located in Granby, CT. I couldn't believe it when I saw it listed on CR for $800 - I was even more surprised when the PO accepted my lower offer.
I don't think he cared so much for the dollar amount it sold for, he seemed genuinely concerned that it would go to someone who would put it back together rather than part it out.
