View Full Version : Gas efi vs propane

We all know that a propane fueled engine is cheaper to run than a carbureted gas motor but what about efi? Efi is maybe 1000.00 more but the conversion is going to run at least 500 with the state incentive. With the fuel economy of gasoline efi would it still pay off? Can we do an efi propane? Probably big bucks.

I am sure Propane is injected but you will not see the same power

Yes, KOHLER has a liquid LPG injected motor and a vapor injected motor, they were just put on the market. Now all we have to do is wait and see which manufacture is going to use them. To learn more about method may look at a website prins.com maker of alt fuel sys for vehicles. To answer your ? yes you can convert an efi engine. One problem, no epa approved sys yet.
