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?

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.

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.

Do a search for Toyota Oil Sludge.

i think the answer is that with time and money one could make a 617 into a gas engine, but why would you want to? the reciprocating parts are very heavy and the engine wouldnt rev like gas engine should.

Thats what happens when you follow the manual's recommendation of 7000 mile oil changes. Do the engineers always know best?

[Hatterasguy]

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