1986 Olds 98 Brougham sedan with a 1987 Built-up 3.8L Turbocharged, intercooled motor.

Over $3000 invested in the motor and upgraded fuel system.

I bought the car from a Navy nuclear-trained mechanic, who did most of the work. He sold it to me out of necessity when he got orders to the west coast.

The turbo, downpipe, and external wastegate are off of the car at the moment, but it WILL start up and run just to move around the driveway (though the turbo oil supply line is dumping into the drain line, and the exhaust manifold is open to the engine compartment, so I wouldn't recommend running it for any length of time). The car also needs a new side-post battery (I'll throw in the old battery to get you $5 off a new one).

Also, non engine upgrades:

I was in the middle of upgrading and re-welding the downpipe flange when I was deployed overseas. Since returning home, I haven't had time to work on it (going through divorce, left the Navy, and relocated to the midwest).

The car is still at my house in GA, but the title and keys are with me. Was told the car is blinding fast, unfortunately, never got a chance to test it out. Here's your chance.

The car will need to be towed immediately, as it has been inoperable for some time and is causing an issue with the Homeowners' Association.

Whoever is the first to come tow it, can have it for $600.

That's pretty much the deal. First come, first serve. First with the cash and a trailer or tow-truck, gets it.
 
Sorry, forgot to put that in the first post.

Located in St. Marys. On the coast, near the FL/GA state line. About 30 mins north of Jacksonville, just off I-95.
