Diesel Dodge Dart Concept

I dont think you will get any of that easy, you won't get 40 mpg, you won't get under 3000 pounds, you won't make 300 hp. You will spend over $20,000, you will never get your money back, you will never actually save money compared to what you spent.
If you want it to be exactly the car you always wanted, to be outside the box, then I'm all for it. But this thread always seemed about doing something to save money. Buying a diesel might do that in certain situations (although I argue 90% of them never will just like hybrids) but building your own diesel conversion never will actually save money.

Not that easy? add a set of sticks anda turbo to the mods listed above. THere you go.

how canpeople such as myself shave a street/strip a body under 3000 lbs with a big block in it yet a 4 banger would not?

Money? Both A bodies I have built have been 25-30,000+ builds and they are far from a SEMA or trailer queen build. I sold the first one and got near every dime I had in it. But WHO CARES? This is a hobby... Look at the cost of new cars. Having 20+ in a new car that is stock and losing your *** on it over the first 5 years. I'm looking at a 2012 cummins with 24,000 miles right now and they are asking 35,000. OUCH!!

while bio diesel may not be worth interjecting veggie bringing is. I have 2 neighbors doing it. one runs 50/50 filtered veg and the other does the whole titration process and runs it straight.
