since your new here i would suggest to read the FAQ at the top of the page, then look for a 928 thats been serviced well and is in daily driver status this way you can spend more for a running car that you can drive now instead of parking a car in your garage for 6 months and only keep spending money to see if it will be able to be driven.
The less you spend now the more exponentially its going to cost to get it drivable.

EG if you spend 1K its going to cost you 6K
If you spend 2K its going to cost you 5K and so on.
Better to pony up the cash now and buy a better running car,
So, if you have 3 k to spend and will shell out another 4 K why not just spend 7 K now so you can be driving.

This info will make more sense in about 2 years if you proceed with your non running purchase.

SRSLY read the FAQ and put the checkbook away till you have read the FAQ,
then watch the boards for a better car.
You will thank me later

First I would drain the fuel,replace all filters,fuel pump,timing belt,water pump..plugs,etc etc....as far as the computer,call Roger at 928rus,and he will tell you where to send it...Roger is a very nice guy
And he will guide you in the right direction as he did for me....

Depending on the year of the Porsche,if you have no mechanical knowledge,then replacing the timing belt will be difficult for you...If it's a dual overhead cam,there is a procedure you have to follow to line up the cams properly so you don't bend them upon installation and final installation.....I purchased my 1986.5 which has a 5.0 dual overhead 32 valve that didn't run...I didn't care,when I tried to spin the motor manually,it just wouldn't turn...took the heads off and noticed all the valves where bent...was very pissed,because the guy said it was running a few ago but had a major flood in the garage and the car was under water up to the exhaust....he lied no water damage found,his mechanic screwed up the timing sequence and bent the valves...but after 1 month and several thousand dollars the car fired up and it's running strong...so be careful with the timing belt...

Bend the valves....forgot to write that sorry...

I have an 86 that im restoring. Be prepared to replace everything rubber and plastic under the hood.

Fuel lines
Vacuum lines and fittings
All wire harness plugs and fi connectors
Plug wires
Timing belt
Power steering lines
Fuel injectors possibly.

Maf and ecu are also possibly out of spec or dead.

If you have a 5-6k budget for refurbishment, then go for it if the block and valves are good.
