You might be able to mount a TDI engine in the Accord from a Jetta but you'd probably have to rig the engine bay quite a bit to get the mounts to work.
Why do you think diesel is so bad? Diesels have tons of torque and can give you decent acceleration. They're not as dirty as you seem to think, actually diesel can be much cleaner (smog wise) than the regular crap we pump through our cars right now, especially if you run it on corn oil.
Your gas mileage is far higher with diesel and thus not being able to get gas at every service station isn't really a problem.
I don't see why it would be so retarded.....
