Need 930 Motor -Cost?

Hi all. First time here. I have an opprotunity to purchase a sweet '77 930. Problem is, its a barn car. Juice leaked into the motor and it appears it sat for years rusting the motor. Needs a complete motor. So I guess my questions are three. First: Rebuild or rebuilt? Low miles and nothing to indicate it can't be rebuilt, but cost IS an issue (concerned about non-matching engine number killing the value too). Second: What should I expect to pay for either a rebuilt or rebuilding the original motor? The price the car was offered to me is very tempting, but the cost of rebuilding it/buying a rebuilt, might be prohibative. I'm a VW guy and if I want to go crazy, I can drop a very built 914 motor in my VW for about $7k (911 cooling, 200+ HP). I'm guessing a 930 motor would be much, much more than that, by comparison. Like Sgt. Shultz, I know nothing about these things. I guess a third question: For an otherwise mint '77 930, what would one expect to pay (low miles, seats look like they've never seen a butt, orig paint, just a bad motor).

F#$%*&@! Last thing I need is another project. I'm going to end up divorced. Ok, $6K to do it myself is much better than $10K. Now, experts in this area, a perfect low mile '77 930, Fuchs, leather, etc. (keeping in mind $6k to do a engine rebuild myself), what would you expect to pay roughly? Thanks again.

What is the mileage on the current motor? Also, if you are even thinking of rebuilding it yourself, get Wayne's book. I rebuilt my 87 930, and really enjoyed doing it. My car had less than 50,000 miles on the motor, so I saved $ and time by not spliting the case. But, if the motor has sat for a long time you probably do not have that option.

Having the 930 in the driveway is definitely a class-upgrade from the VW, if you ask me.

The goal is to have more teeth in your mouth than cars on blocks in the yard. If you can do that, you are safe.

I don't understand what made the engine go bad? What "juice" are you talking about? Did the aluminum of the engine oxidate from this substance? This does not make much sense to me right now. If the car is just sat up with low miles, all you may need to do is take it apart, replace the seals and put it back together. That's much cheaper than 6k.

The early turbos have their place in the market, but unless you have documented low miles and real good condition they aren't worth more than low 20s.

Why would a 930 end up in a barn??? I usually only find 1977 oldsmobile cutlass supreme 4doors with a straight six, when I go look.

considering the $20K top value at the moment, the potential $10K rebuild, cleanup effort, room for some profit, (breaking even sucks), even $7500 may be a bit steep. try for $5K.
