1990 black audi coupe quattro with tan leather interior with the legendary 5 cylinder engine. Approx 190,000 miles one the body but less than 10,000 miles on the rebuilt engine. The entire engine was rebuilt a few summers ago. Nothing was overlooked. All new seals, gasktes, rings, bearings etc. The engine was honed and the head was completely rebuilt and a few valves were replaced. 

The new pistons are from an audi NG. engine to lower compression to around 8.0:1. I used an Audi AAN exhaust manifold (from the early audi s4 turbocharged car) The car has a new k26/t04e hybrid turbo. Custom charge piping connects it to the front mount intercooler. From there it goes into the AAN intake manifold and boost is controlled with a tial bov and an audi external wastegate. The custom 3" turbo back exhaust and borla muffler sound amazing42 lb injectors provide it with enough fuel. Custom fittings connect the 034 efi fuel rail with the stock hard lines. ) 

The car is run with 034 efi's IIb stand alone engine management system with is controllable via laptop from inside the car(i have an old laptop with the software that I will give with the car) This system is made by the pioneers of audi 5 cylinder engines, check them out. It is very easy to use and extremely powerful. A custom short radiator takes care of the cooling and the fan still turn on and off like a stock car. mechanical oil and boost gauges monitor the engine from inside the car. 

The exterior is in ok shape for how old the car is. The previous owner drove it through a fence so there are scratches on the side and top. Its nto as bad as it sounds. Other than that the body is pretty straight . There are a few door dings but they are very minor for the age of the car. 

The interior is in great shape overall. The tan leather has held up very well and still looks great. There is some wear ont he shift knob and steering wheel but again, it is minor for the age of the car. The stock radio is still installed but it does not work. It has an anti-theft device where if it the battery is disconnected you need a code to turn it back on. The origional owner didn't write this down anywhere so i have no idea what it is. It worked perfectly before the battery was disconnected. Also the car has no A/C. unfortunately it had to be removed to make room for the charge piping and oil lines. The sunroof just started acting up, it slides perfectly but it doesnt tilt so well any more. Both the driver and passenger side window regulators work (a rare thing in these cars) the drivers side was just replaced at the same time of the engine rebuild.
