The Rugged 616 & 617.... made into a gas motor?

[Mr.Kenny]

I have wondered for years......wouldn't the 616 or 617 make a really rugged gasoline motor?..... Power and durability!
I wonder what it would take?
Lowered compression & fuel injection system or cabrurator & a new cam profile. Mount a distributor and spark plugs instead of glow plug.........


Hey! It sounds like a done deal!

Why mess with perfection? Instead look at performance mods. to have it get HP close to a gas engine. Increased boost and intercooler would help.

Do you know that you are playing with fire?

You had better have a flame suit on before posting such sacriledge in a diesel forum!

Or you will have visits from folks like these:

Ruggard gas motor? Pretty much any 4 cylinder Toyota makes, Subaru makes some unkillable engines as well.

On the Mercedes end, the good old M119 V8. We all wonder, can one actualy be worn out? Currantly I'm leaning towards no.

maybe your onto something. Brand new cars have really high compression and direct gasoline injection. I wonder if an injector pump from a 280sl would fit?

[Kynetx]

I was thinking something similar the other night while drifting to sleep. Since propane doesn't get hot enough in a diesel combustion chamber to ignite you'd need spark. So fit a spark plug in the pre-ingition chamber and you'd have a 22:1 propane engine. I bet it'd go like stink and be incredibly efficient to boot.

I've seen tractor pullers do just that. They take a diesel, add a spark plug and run it on methanol.

It might fit but it doesn't put out nearly enough pressure for direct injection. You're asking it to spray fuel into a combustion chamber at 200psi... then add a turbo.

Cummins has done that with the 6BT diesel that is widely used (Dodge trucks)
They make them into natural or propane spark fired engines for stationary useage. In Diesel form, I have read of some Dodge pickup trucks going 1,000,000 miles without an overhaul.

interesting. do they keep the compression the same?
and the turbo?

Sure they will run to 1M miles, if you put 100k+ on the thing a year!

Yeah, it was dead when I got it (head gasket), but I bought a '77 230 for $100. It had 789,000 miles on it. How many times had the engine been rebuilt? No clue. What is the designation for that engine (single carb), anyway? If properly maintained, I bet it would hang right in there with a 616.

I remember something about Caterpillar's production spark-ignition engines using blocks from their diesels, so it would be possible, but I'm with hatterasguy. The Toyota 22R/22REC engine (used in their pickups and 4runners through the early 90s and the mk3 celicas 82-85) was bulletproof.

I bet it would. The pump portion is just like a diesel pump isnt it?

Do a search for Toyota Oil Sludge.
