Actually, i think the 2002/2003 C180 Kompressor is an all new engine, featuring TWINPULSE whatever that is
But yes, i think the M111 supercharged was fitted in 2.0 capacity and supercharged to the 1999-2001 W203 C200K (and E200K, CLK200K, SLK200K). I'm sure you're right, it was probably beefed up.
the new 2003 TWINPULSE engines (with balancer shafts) are:
C200K 163bhp (same bhp as previous C200K, even though it's a new engine and in fact only 1.8 capacity
C230K 192bhp (again, replaces the old 2.3, and is really only 1.8)
From the MB website
The 4-cylinder models of the C-Class sedan are now powered by a newly developed 1.8-liter DOHC supercharged engine. The cylinder head and crankcase, made of high-strength aluminum alloy, reduce the powerplant's weight. Despite the reduction in displacement, modifications made to the variable valve timing system -- which controls both intake and exhaust valves -- and those made to supercharging systems, enhance the unit's power output and torque, while at the same time reducing its fuel consumption.
The new four-cylinder engine comes in two versions that share basic components but differ in the tuning of the control unit. The normal type powers the C180 KOMPRESSOR, while the higher-power unit is installed on the C200 KOMPRESSOR.
Interesting: 'but differ in the tuning of the control unit' - Does that mean you can chip a C180K to a C230K ?
