This is a story of turbocharging my Mercedes and it contains plans that change many times over and some of the plans will never be realized.
My car is a four cylinder two litre Mercedes-Benz 190E (type W201) year model 1990. I bought it in april 2006 with 195 000 miles (314 000 km) on the clock. I had read about finnish Merc diesel turbo freaks who ran 11 second quartermiles and that made me interested in turbos. There are quite a few diesel fans on our Mercedes forum and there are some english topics, too.
The turbo is a BorgWarner (KKK) K03, which is used in the VAG 1.8T-five valve engine. it should spool up early, we shall see. I thought I could use the remote mount system ( Rick Squires). I may use the Saab APC system to control boost pressure and knock. I got help from the guys at the local Saab club and Cosworth club , who also play around with turbos and Bosch fuel and ignition equipment.
I bought a used cooler (Ford Focus heater) for the auto trans and a used radiator from a Saab 9000 T16 (core dimensions 500 mm x 400 mm x 36 mm) with electric fan.
I found a great instrument for testing my cars performance. It is an acceleration meter from the finnish firm Paetronicsin . It is based on acceleration sensors and the speed and distabce are calculated. It ranges to 124 mph (200 km/h) so it mey be enough for a while ,-) It records the time and distance at fixed speeds so I will interpolate the results I need in the quartermile run.
I added a trim pot in series with the water temperature sensor to be able to manipulate the temperature signal to the ECU. I also added a switch so I can activate the cold start injector if necessary.
I was at the local Bosch shop Klaukkalan Diesel for a dyno run before the turbo conversion and found out that quite a few horses have run away in 17 years ,-)
