Engine tuning options
Engine tuning options
I'm in the process of buying my first W123, a 1978 300D. What I'm wondering is what my options are for engine tuning, and what I can do easily and cheaply to increase performance (I'm a college student and therefore have no money). I've gathered that the main idea in performance mods for diesel cars is to increase fuel delivery, but I'm not so sure how to go about that. I guess I want larger injectors, a higher capacity fuel pump, stuff like that. What's the single best mod I should do enginewise?

Being non-turbo its already at maximum performance. Changing the air filter and exhaust system will do nothing and adding more fuel will do nothing but go out the exhaust.
You can add a turbo, but thats a fairly complicated ($) process that will significantly reduce the engine's lifespan.

Not only easier, the turbo models are the only ones that can handle more power.
