22r propane conversion

[brimy311]

Well, after steeling the idea from nyxis I decided to try to put together my own propane conversion for my 22r in my land cruiser.

After doing a lot of research and not finding anything, I found a number for acme alternate fuels in Minnisota. I called and talked to Dave, he helped me though all the parts.

So for about $480 I got everything I needed minus a K&N filter and LB tanks.

Prices vary based on length of fuel hose, type of fittings and how many forklift tank brackets you may buy. I was right around $480 shipped to my door. I bought a few extra fittings that I did not end up using. I also bought some other fittings from lowes.

This Cobra converter is only rated to up to 125 HP. So if you plan to run this on a turbo or a motor with more then 125HP, you would need to get a bigger converter. The 200m-2-2 carb/mix is plenty large enough to a very large array of motor sizes.

Fuel filter and vaccum fuel lock, This guy runs on vaccum pressure instead of a 12V+ wire. I like this idea for if my land cruiser was to get out of control and happen to die, it would lock off the fuel. With the 12v+ wire fuel lock, you often run the to a hot wire on your column and if you needed to get the fuel locked off, you would need to turn the key.

To figure out your high pressure hose length, you need to measure from where you plan to mount your tank to where you plan to mount your filter and converter. Be sure to get enough hose to also make a line from your tank to the bulk head.



I will get some pics of the install stuff soon.

Don't forget that everything is measured in propinches.

propinch (prō'ĭnch) pronunciation
n. (Abbr. proin or proin.)

1. A unit of length in the propane industry, equal to 1/12.54 of an imperial foot.

[Middle English, from Old English ynce, from Latin ūncia, one twelfth.54 of a unit.]

Nice!

I thought about it, if I was going to run a 22R in the flattie.. but looks like I'm going 4.3 V6 instead, its already injected..

[brimy311]

here are some detailed pics of each part

[brimy311]

I have been fighting to keep the 22re running good. I must have a bad ground in the harness or something. But I am tired of messing with it. Plus I had gas, working with gas, filling gas, the smell of gas. So for $400ish it gets me a chance to clean up the cruiser. I really like how simple everything is, and you can idle it down to 300rpm!

Not to mention grilling some burgers on the way down the road. :tonka:

[Kawierider]

very cool.

how long will a propane fill last you ?

[Haggar]

Yes, when you have it all tuned up(if you don't already), give us some stats on how much wheeling/driving you get per tank.

That seems to be the hardest info to get from anyone who's done thing. If possible, compare to when you were running gasoline.

The common number is a 10% loss in efficiancy.

[Haggar]

Yeah, but I've only seen it thrown around as a ~10% loss in power, never really seen anyone actually talk about a A-B comparison in range/drive time..

[brimy311]

Yah it will be 10 loss in fuel economy, but will be an increase in power. As propane is the same as running 110 octane. On a 33lb tank (about 8 gallons), I should be able to wheel 2 full days. I will verify this stuff soon, once I get it running again. I have a lot to do, as I am redoing all the wiring in the cruiser now as well.

[Kawierider]

Wouldn't that increase in power only come into play if your running more compression......or more spark advance ?

your just putting this conversion on a motor you built to be a gasser right ?

[brimy311]

It is a stock 22r motor. You actually advance your timing from stock to take advantage of the octane. I will post the timing numbers when it is running.

[nmeinc]

when I got my parts for mine I went with a electric shut of. as soon as you turn the ign off it stops the fuel.
I still need to make an adapter plate and get tank mounts.

why the bigger mixer? the 22r should be fone with a Impco 125.
let us know how hard it is to adjust.

definatly a great write up

[brimy311]

I could get the best price for the 200m-2-2. The impco125 was more $$

[Kawierider]

Any updates ?

[brimy311]

I have all the propane stuff hooked up and ready to go. I am building my own wire harness, so I probably will not get it up and running until some time in september. I am not wheeling until october, so no hurry.

[KILLER"B"468]

I hav ebeen researching and I really think I am going propane instead of Holley projection.

[Kawierider]

to both of you ......

[ScOoTeR]

BTT, Princess.

What's the status?
