I'm in the process of swapping out a Gasoline engine in a small pickup (My little Mazda) to a Diesel.

I've been calling around to the local Dept. of Environmental Quality and the EPA in Washington D.C.

I want to know about the guidelines for registering it, as the VIN will run and return as a Gasoline vehicle.

Has anyone swapped a Gasoline engine for a Diesel? Mechanical and electrical aspects aside, any paperwork tips anyone can provide?

 

I have done this in Az & Calif with only a trip to mvd for verification of required emissions systems for vehicle modle year (not engine year) and the title was flagged as alternative fuel conversion to get away from the vin encoding for gasoline. arizona only cost 14.00$ & I do not remembrer Calif fees 20 years ago.

 

I'm doing it to my Super Duty, it was a 5.4 gasser. As I was reading the DMV info & talking to others, it's just a matter of getting the correct paperwork filled out, then the DMV looks to verify the engine is rated for highway use, and of course the fees.

 

Out here in corn country we operate under a don't ask, don't tell policy But we have no vehicle inspections and no emssions testing either so I can't imagine any circumstance where it would even be an issue.

 

I did it in Iowa, simply told the DMV to change it to diesel, and they just did it, no issues...

 

I'm thinking about putting a 6.9L IDI my 55 F-600.......I'm gonna keep it a secret!

 

They used 6.9's in IH med duty trucks, so why not?!? Wont be a speed demon, but will be adequate & deliver good economy.

 

Our first diesel bus was a 1985 60 passenger with 6.9 LD. We bought it at the time International stopped producing gasoline engines so there was some good price concessions in order to try to switch their previous gas engine customers over.
It was rather gutless, used a quart of oil every 300-600 miles, International did a ring job on it around 50,000 miles under warranty, it dropped a valve and broke a cylinder wall about 100,000, the rebuilt replacement engine went 50,000 miles before a roller tappet failed and destroyed the camshaft and that was the end of Soloman Grundy.
Even after all that it still was a better choice than any gasser bus available at the time and we have bought nothing but diesels since, just no more 6.9s
