would you fit any pre-heat setup into that c240 that you intend to put into a honda legend? btw which generation and body style would you consider to retrofit with the diesel?

Actually the glow plugs already provide an easy cold start capability pero an air intake heater could already be added. For the biodiesel tank and fuel lines it would not be required, and it can already run pretty well with waste palm oil or coconut oil. A filtration system, by the other side, is almost mandatory to ensure the reliability while using waste frying oil. That centrifuge setup used in some Russian trucks seems to be a good option.

About body style and generation, I prefer the 2nd generation coupé due to its sporty look pero maybe will get a sedan because what I want is not exactly a sports car. Would be cool to show how a luxury car can be, by the other side, eco-friendly.

Feel free to question
