So I'm at work today, and out of all thing I've learned, theres a vortec 4.3 engine in our Toyota 15000lbs forklift!

so I'm just wondering, what else has the vortec in it?

 

Lots of boats use the 4.3, but I'm not sure if they're Vortecs or not.

 

We have a few Toyota fork lifts at my job, too. I'll have to check and see what they got under the 'hood' now.

 

Ditto on the boats.

 

I did know Since I was looking to get a spare engine to my ride. They differ with an upper intake however, and costs approximately two times more.

 

Wonder what all is different besides the intake/fuel injection to get them to run on natural gas or propane or whatever? I bet the cams are different, I wouldn't expect a forklift to be running up to 5k RPM, either. Bet the powrband is pretty low

 

Actually, LPG installations do not involve camshaft change. You just have to:
- cut off the fuel supply
-"fool" the O2 sensors operation
- inject the gas directly into throttle or injectors (which is kinda complicated due to the spider assembly)
... and that's all. OFC there are another options, with carburetor it is even simpler.

Camshaft are a subject to change, if You want to run Your engine on alcohol. Yeah, I've been thinking whether You could run the engine on distilled potato or grain fuel. Technically possible, but for me it's a subject to develop while Mad Max era.

 

Hmm. Today I learned!

 

A simplistic explanation
The old school carb type was about the same,
The units that I was around has a gasoline shut off valve along with a LPG shut off valve that gives the option of running either fuel.
LPG conversion is sort of a closed unit that fits on top of the carb. It has a flip valve for air intake during gasoline usage and shuts during LPG
There is a heat exchanger that is coolant heated that turns liquid LPG into a vapor state.
Metered vapor from the exchanger is sucked in thu the carb. as air would be.
LPG was considered a dry fuel so back in the day when we run LPG in our crew cars we also added a few OZ of marvel mystery oil when we filled the tank to help lube the top end. without the valves would pit and burn. But this was also early 1960 era cars before the engine changes for unleaded fuel.

 

Well dang, we've got two LPG Yota lifts in our shop that look just like that (actually we've got 3 that look like that, but one is diesel...), I'm going to have to look up their skirt and see if that's what power's them
