This is my 1981 Mercedes Benz Turbo Diesel. The engine in this car is a 2.998L (3.0L) Inline 5-cylinder Indirect Injection Turbo Diesel. Its coupled to a Mercedes Benz 4-Speed Automatic Transmission. Independent Rear Suspension with Center Mounted Transaxle.
The engine came stock with a T3 Garret Turbocharger and I upgraded the compressor side with a 60 trim Ford SVO compressor. I run my turbo unwastegated anywhere in the range from 17psi up to 26psi under full load. The engine has never been opened up or internally modified. I have installed a 0-30psi boost gauge and a 0-1800F Isspro pyrometer in the exhaust manifold (pre-turbo).
I also intercooled the car with an Audi S4 intercooler modified for air/water use rather than the stock air/air which it was origionally designed. The intercooler's size is adequet enough to support up to ~400HP so it is plenty large for this small of an engine. A mercedes circulation pump runs a closed loop system through a temporary radiator mounted in the front bumper area.
The Injection Pump has been rebuilt/modified to provide greater full load fuel and less torque backup. This modifications, along with the intercooler provide must more power and an enjoyable driving machine.
