Geo Metro LSI convertion to Diesel?
I don't own a Geo Metro but if I were to convert a 97 Geo Metro LSI to diesel, Which engine size would be the most efficient in the car?

It's beginning to sound as if it's more valuable to buy an 80s Mercedes and convert it to run on Biodiesel.
Edit: What happened to the first reply? Did the person delete it? |
Seems like a Volkswagen engine would be the easiest option to make a fully EPA-compliant Diesel swap into a Metro. Other options would be pretty much limited to some stationary or agricultural small engines such as a few ones from Kohler, or that Caterpillar 1.1L 28hp 3-banger, or the one out of some side-by-side ATV such as the Kawasaki Mule, but since they're not exactly road-legal it would be harder to register the vehicle after the swap. If you could get a wrecked Volkswagen TDI to take the engine, electric harnesses and occasionally the gearbox (altough I've already seen some Suzukis fitted with Volkswagen engines retaining the stock gearboxes, but I'm not sure how long would the one of a Metro last coupled to a TDI), that would be the best setup.

That is alot of work. Find an old rabbit diesel. Or live with the gas. Round here diesel is more per gallon.

It is a lot less work to buy an older diesel Mercedes, but your fuel mileage will not be very good, they are heavy and less aerodynamic. But there is no "conversion" to biodiesel, you just pour it in the tank and drive. An old Rabbit or Jetta diesel would be an amazing find. You can get 50-60mpg with only mild hypermiling techniques. |
Thanks for the helpful replies. Perhaps I should narrow my search: I'd like to retain use of a Scangauge II so I imagine I should first purchase a Metro then find a junked Volkswagen or some other small-engined Diesel car. I know 1.0-Litre Diesels exist but I don't know much about them or if any American cars even have them.
I haven't even the car yet and I think I'm pulling the cart before the horse. I imagine one could get over 85 MPG out of such a conversion plus deletions and Aerodynamic mods, Though... Edit: Please take my reply as what it is: Some guy's reply on the internet. I was just imagining I could get such a high MPG figure out of such a car, And perhaps I can too but I haven't done it. |
Half the trouble is going to be fitting a diesel engine in the engine compartment, a VW engine is not going to fit, at least not from any VW's that were sold in the USA and VW put the smallest diesel engines in any diesel car in the USA so you are going to have to go with something from a very small tractor or generator, then you are still going to need the offset transmission that you'd get in a car with the larger 4 cylinder engine.
Other problem you are going to have is that the stock Metro engine is very light, I think the 3 cylinder one is around 70 pounds and the 4 cylinder one is around 90 pounds, a diesel engine is going to have a cast iron block in be closer to 200 pounds. |
Not positive about the details but I was under the impression the geo metro was also sold over seas and also the engines found thier way into toyotas also. So I believe if you find the rite member from elsewhere they should be able to redirect your effort.
If not I would go for a 3 cyl perkins with a converted turbo that is pulley driven converted supercharger, its easy cheap and bullet proof. Thier commonly dismissed there are also diesel briggs n strattons and kohler diesels but that is a stretch for sure. |
There is a rabbit truck diesel for sale by me ok shape but 3000$

One of the easiest Diesels to swap into the Metro would be the Briggs, which is actually a Daihatsu engine and was a factory option for the Daihatsu Charade in some markets during the 80s and early 90s, but as I quoted before, it would be hard to get the Metro registered after the swap due to the year of manufacturing and OBD-2 compliance.

I know not of registering a car after an engine swap, Would it even be hard to register a 97 Metro LSI if I stuck a 1.6 Litre VW Rabbit Diesel Engine in it? Though at this rate why not just drive a Rabbit. Can vacuum gauges be added to Diesels too?
I'm beginning to think perhaps I should just buy a Volkswagen. |
You will have so much work ahead of yourself. Just buy what you want. If you want a diesel get one want a vx get one want a metro get one. I want a polo blue motion to bad not in USA. Around here you buy a car they don't know or care what motor is in it. No inspections or such. If you live in an area like that good luck. Diesels if I remember correctly prOduce very litlle vacuum. So no a vac gauge will not help your driving habits.
