I'd say far less than that. IF it is a turbo, then 3k would be top dollar. However, be very careful if you are thinking about buying this car. The stock N/A front bumper IS NOT a direct bolt on (or the other way around) - front fenders are different. Add to this the amount of work needed to convert the N/A's front end to accept the intercooler and other "turbo" goodies and the story begins to fall apart.

 

I'd be willing to buy your turbo longblock with no manifolds and no front acessories for $1000. Assuming everything is in as good as condition as you say.

 

Id say 7-9, but at any rate thats better than 3.

 

Upon closer inspection with Photoshop the car has no Turbo rockers (the blackaero pieces below the side skirts)either. I'm not inclined to believe the previous owner bought the 944na front end either - the Turbo front bumpers are far more plentiful and probably cheaper, and as has been said, a regular 944 bumper wouldn't fit the nose or the fenders of a 944 Turbo. If you want to sell your engine you should probably take a picture of that - instead of leading us to believe you're lying by not showing us the back end Turbo decal, or the engine bay, or the VIN, or anything.
