Propane for a 62

[Rogue62]

Did some searching and see a lot of info on converting 40/60 series to dual fuels but nothing on converting a 62. I found a couple of links: http://www.propaneguy.com and Propane Conversion Kits. They only list [FONT=arial,helvetica]carbureted kits and nothing for the EFI. In a couple of posts I saw a picture of a 62 that had been converted but it wasn't in the U.S.
I have an email out to the propaneguy but thought I would ask here also and see who answered first.


Thanks

real close to the carbed kit, as long as its a tbi, if not tbi then it gets a little complicated with injectors and fuel rails and stuff

I got an email back from the Propaneguy. Is the TBI what he is calling the manual propane kit? How does using the manual in propane over the injected propane effect the power/mpg of the truck? Does anyone know what comes in either of these kits? Model/Part numbers? Are there and copies of the install directions floating around?

"Two possible under hood kits:

1 Under hood duel fuel .manual propane kit (no electronic in propane mode) impco vapor induction....$800.00us

2 Universal under hood duel fuel vapor injection kit with electronic controls(best kit) $1900.00 us...

(i have the install/setup cd for $25.00 if interested..will take it off kit price)...then you need propane pressure hose( can supply certified hose need length...$20.00 plus $10.00 a foot) and a liquid service valve propane tank with stop fil valve......roy"

Thanks

Seeing that the 3FE motor and the TBI system are two different beasts I doubt it will work with your application. The overseas propane 3F you saw was probably a carburetor version of your 3FE. You will most likely have to source the carb intake version for that motor and then you will be able to adapt a propane mixer to it. If you are lucky it could have the same intake pattern as a 2f and with that you can use the holley 2 barrel adapter and the Propane Conversion Kits kit to mate to it.

In my original email to the propane guy I gave him the engine specs for the FJ62 and asked about a dual fuel set up. The two options above were the response for the EFI motor. Sounds like the first option was to remain EFI when running gas and for it to be a manual propane using the vapor induction mixer? Does this sound possible?

You will have to forgive my lack of understanding as I am new to the cruiser world as well as being new to the mechanical workings of the automobile. Could you also fill me in on what TBI is? I will do a search and see if that pulls anything up on the subject.

Thanks again.

TBI = throttle body injection (as opposed to multiport injection)

I doubt a propane setup would be simple, as you'll have to disable one aspect of the computer engine control (the injectors) while maintaining another (spark management). You'd need some sort of piggy-back system, and I expect that would have to be 3fe specific........ But I'm just talking out my arse....

Considering the prices quoted, how long would it take you to pay out on the system?

Thank you for clarifying that for me.

A long time for the 1600 dollar package but if the manual 800 dollar package isn't that complex then I may be able to piece it together for cheaper then the package price. Still in that part of the research. Propane is running about 1.00 a gallon cheaper at the moment in my area. Also think it would be a cool mod to preform.

I'll throw something in here. AutoTronix developed a control box to run dual fuel with the TBI computer. When you flipped to swtich, it would kill the power to the stock computer and advance the timing automatically. It also used the chevy O2 and Knock sensors. To the best of my knowledge, nothing lilke this exists for the Toyota 3FE computer. I have one of the TBI computers and it works as far as I know though. I'll sell it to you cheap and you can play with it and see if you can make it work with the Toyota computer. PM me if youre interested.

This system assumes your going to use the TBI butterflies to regulate the pane too. hope that helps dude and welcome to mud

One more thing: Got propane (dot) com is great for people who are totally stupid. If you are smart at all, you can put a system together for 1/4-1/2 the price. I've got everything but the HP line at this point and I've spent $114 so far.

That is what I was hoping to do also. At this point I am totally stupid but very mechanically inclined just not with autos yet. I was using the gotpro and proguy for research. Thanks for the input and helping me get over the 10th mark

the lpg system is pretty basic,just do your homework and you'll be fine

That's if you are buying used parts. I have priced out all the parts brand new and the mixer alone is $150, another $170 for the model E vaporizer, $40 - $50 for the high pressure hose line depending on the length, another $75 for the vff30, don't know how much on the electric unit. Then you will need to buy the throttle body plate which you can get from Impco but I don't know how much that is either. The Y pipes for the radiator fluid and the big 2" hose from the vaporizer to the mixer. Plus all the random fittings needed to attach everything together.

Yes it is cheaper if you source the parts separately or you can get the whole kit in one shot and the service that comes from buying from Cary at gotpropane.com

You're right! that does assume used components...

Not doggin Gotpane... Its definately a PERFECT setup. I personally don't have the cash for a setup like that and I know a lot of other guys don't have $1100 either...

One thing to keep in mind though. All USED components can be re-built on the hood of your rig in 5 minutes with a screw driver and the diaphrams... So don't necessarliy be scared of "used" parts in this case.

His jeep kit is $875.00, and another $25.00 for a used holley 2 barrel adapter from someone off mud or local guy. Unless you are talking about doing the duel fuel route then yes it will be knocking $1100.00.

Yeah, thats what Im talking about.

$875 doesn't include tank though. New tanks sell for $160 around here. I bought a re-certified (5 year) tank for $45

LT, I'm really not doggin the dude's kit... For all the guys that DIY, theres a cheaper way; thats all I'm saying. Its not going to take away business from him by me saying this either.

Search pirate for 3 minutes and you will find a shiz ton of guys who have put IMPCO 125's from forklifts straight on 22r's and have built the whole thing for $100.

 

[LT]

That would be one under powered mixer since it is rated at 235cfm even for a 22r that wraps out at 8,000 rpms. The forklift mixers are meant for very low rpms and slow speed which isn't the ideal set up for a daily driver or for a wheeler when the power is needed.

The Impco 200a mixer is rated at 345cfm up to a 215 horse power motor. The throttle body from Impco that mimics the Holley 2 barrel set up is AT2-13-1 however this butterfly design is a giant one barrel instead of two.

Look under the 425 mixer specs to see the different throttle bodies available.

Correct Again! A 125 is definately under sized for a daily driven 22r. However, if you're running dual t-cases and its a trailer-queen - great setup.

Anyway, back to the dude's question. The answer is: There is no easy way to dual fuel with your 3FE fuel injection. Again, if you want this controller, you're welcome to it. I will sell it cheap in the name of science... PM me.

 

[GAS-A-LOT!]

Aight! Cant you just use a mixer with the intake? past the MAF? Or pre-MAF? Then, just get a switch for the injectors? You know, the computer thinks its running/using the injectors but in reality, the injectors are off? and running on pane? All them sensors are pre-or post combustion chamger right? I mean... YOu could fool the computer that way couldn't you?


Guys... I think that there is a way.

 

[kitb]

I think GAS-A-LOT is right, you just turn the stuff off and trick the computer, at that point you have a programmable dual curve box for your dizzy that switched to an advanced curve for the lpg, because of the higher octane.

 

[GAS-A-LOT!]

You could probably tap into the line to the injectors. The computer will be sending the signals but the injectors would be off line. Ass far as the dizzy? Well...

Oh one thing. I saw a manual control (like the choke cable/knob) for the dizzy to control the timing on a friends model T. I know its old technology mind you, But none the less... it worked. Keep the screw loose, tie in somehow with the cable and control it from inside the cabin.

Just a thought.

Ha, that would be a cool way to dial in the timing to get the most out of whatever gas you happen to be running at a given moment.
