I only had a std 1.8 non turbo escort mk4 but turned mine up(lucas cav) quite a way, no smoke, but around 8mpg more, as it developed much more torque, had indicted 112mph, evetually but 0-60 was still measured in weeks!!
You always will see the diesel in car headlights it due to the unique properties of disel emissions and the light spectrum that headlight bulbs work on/at.
