Can anyone recommend what I can add to enhance my engine's potential....I was a never a big fan of 4 cylinder cars, but my '03 C230 (hatch) was a gift from daddy I love my car but I would like it to be more powerful....at least at a V6 level

 

K&N air filter and Tuner-Werks ECU will be a good start.
ECU tuning ouputs 205hp/215lbs ft with 91 octane.
Tuner-Werks pulley kit for your car is under development.

 

Is that pulley kit going the work on all 230 Kompressor's?

 

No, it's for 1.8L only.
2.3L pulley is already available.

 

Any eta on the pulley for the 1.8 K?

 

For 1.8L, Renntech pulley is available.
