what would it take to put a diesel engine inside a non-diesel car.?

Question

I would like to make an early 1990s Mercedes 300E diesel. Is there a lot more than just swapping engines? Any idea the cost?

Answer 1

Transmission, torque converter, and differential are different. You will need to install all the switchover valves, vacuum controls, radiator, and coolant header tank. New fuel plumbing including tank. Electronic idle control. Vacuum plumbing. Don't forget the throttle linkage, including all the bellcranks, ball joints, and microswitches.

If you install the correct 2.5 turbo motor, you will also need the air cleaner assembly including air mass sensor, and you'll need to replace the right front outer and inner fenders (the fender has to go because the turbo Diesel air intake is through the side of the car rather than the front).

Then you'll need incidental stuff, like the washer bottle and a new wiring harness. You'll also have to replace your instrument pod (because you need the correct speedometer and Diesel tach), as well as your ignition switch. And you'll need a complete exhaust system. It's a long, long list of stuff.

Better sell your car and buy a Diesel.

Answer 2

Cheaper to trade in the car for one that's setup as a diesel--have to swap fuel system, engine control components and computer, wiring harness, engine and bolt-on components, suspension items since diesel is heavier block, etc...Plus, you may have trouble reselling and emission testing if it's not original. Wish it were easier too.

Answer 3

It can be done since they made a diesel model of that car. But I expect that it would be cheaper to just trade for a car with a diesel engine.

Answer 4

Yahoo authorities are very much sensitive about ugly words and suspend membership if abuse reported. So I dare not give you a befitting reply.
but I know the reply.

Answer 5

yep, the electrical system is not compatible. . diesles have different sensors and have glow plugs.
