propane toyota 22R

Dose anyone make a kit for a 20R or a 22R that would bolt right onto the carb location. Or has anyone made and currently use one. Also what effect would it have one Ca. smog laws?


Thanks
Chris

Pros:

runs at any angle
easy to tune
simple setup
no computer
cuts down on wiring vs fuel injection
no fuel pump to take a dump
less parts to give up on you
small gain in torque


Cons:

small loss in HP

Another issue to remember, cold weather, me and drm talked about this a while back, but that can be corrected by running a tank heater... I am not sure on all the legalities, but in this state, i thought a certified person had to do a certain part of the instalation, but not sure....

I have noticed NO loss in HP, but I'm only getting 7.75mpg.

so when you run out of propane on the trail your screwed right but i guess you would have to carry an extra tank with you at all times. i don't know about other places but i know to get a tank filled for a gas grill around here is like $25..seems cheaper to just stick with gas..
but like crash said,winter weather would suck since the gas shrinks..just like using torches in the winter,it goes very quickly

What kind of absurd arguement is running out of fuel on the trail?

If you aren't smart enough to carry enough fuel - it doesn't matter what fuel you run, you are still an idiot

Even if you did run out of propane, you can easily make a "jerry can" out of a good old common BBQ grill tank, and a conversion hose. I am not too worried since I will be running a 38 gallon tank, but don;t ell me it is hard to find BBQ grill propane tanks EVERYWHERE

BTW - do you realize you don't burn off the gas, you burn off the liquid which is converted over before it leaves the carb?

Another lil trick, an adapter to run the one pounders just in case...
Lets face it, you will have to run the tanks low each time,, stopping every time you want to wheel to top off the tank is going to be a pain... But I do think running propane is a cool gig...

I've read that the engines are clean as a whistle after they've been run on propane, burns cleaner, les oil changes, les maintenance in general. You don't have to mess around with emissions testing either.

Thanks for the input I would guess that the only hard part to find you l be the injector for such a small engine. I know you can buy kits for chevy and fords I was just hoping that I had missed a search for a injector that would just bolt onto the stock carb location. I do like the running out of Propane comment, Last time I checked they didn't sell gas ( or Deisel) on the Trails eather. My daily driver is a Deisel anyway, so I am use to looking around for a sourse of Fuel.

Thanks
Chris

I was thinking of using a injection system off of something like a Forklift . Making the adapter for the intake would not be a problem, Just finding a big enof one off a forklift might. any input on that

Did you even read the link I posted above?

I sure don't think you did, considering the questions you are asking...

First, nobody I know of makes a kit for a 20r/22r. I used parts from a forklift- bottle,impco "J" vaporizer/regulator, and an Impco model 100 mixer. Hmmmm??? this sounds familiar
As for Cali. smog,your porked.
I went to the smog ref. about a week ago. You need All the origional smog equipment, including:3-way CAT, PCV, EGR, Air Ijection System(smog pump),O2 sensor, elec. carb heater,computerized spark control, CPU and all the related feedback sensors.
What you dont need is: fuel pipe restrictor(DUH), and thermostatic air cleaner.
Most of these required smog devices would have little or no effect on a LPG motor. The smog ref agreed, but said thats the way the law's written and he has no athority to change it or make exceptions.
The topper is, even if you could have all these devices hooked up and operational, the propane conversiopn "Kit"(which doesn't exist) must have a pre-approved C.A.R.B. E.O. #.
In short, a LPG converted vehicle can not be smogged unless you use a pre-approved "kit" with a C.A.R.B. E.O. #.
It runs great in a 2700lb. Sammi/buggy though Good luck

So, after reading that other BB's post, the general consensus seems to be that you should only do a LP conversion if your motor was built for it.

Hmmmm...

Depends


engine really needs hardened valves, higher compression ratio is good, and places like here in TN where smog is not something we have to worry about...

As a point of interest thousands of cars etc are converted to LPG in OZ and most are dual fuel, eg petrol and LPG.

Some of our maufacturers, eg Ford supply a LPG car only and these are popular with Taxis.

My 2wd 22R Toyota flatbed is dual fuel. It runs petrol or LPG and it has a switch on the dash that I can swtich across to either whenever I want. The benefit though is LPG is less than half the cost of petrol. My LPG tank holds about 70liters.

But these complete kits can only be fitted by licenced LPG installers as any naked flame near a gas leak means kiss you a*s goodbye so it isn't something to be messed with.

DRM, do you have a list of the parts you have for the 22r ? Is this, ,impco "J" vaporizer/regulator, and an Impco model 100 mixer, the parts you are using ? Pic's would be good too if you have some.

I was going to do an EFI swap on my 84 4runner but this seems like it would be a little easier and maybe better. I already have an 85 EFI truck for the swap. But I'm not looking forward to all the wiring. It's going to be an all tube buggy.

I ran an Impco kit on my '74 FJ55 with F engine. Worked fine, only change was MPG went from 13-14 down to 10. Check with any good propane distributor and see if they have a kit.

In CA, you will still have to meet smog with propane and you will have fun finding a place to test it for you. That's why I no longer have my FJ55, could not find anyplace to smog it in the SF Bay Area (back in the early 90's). I ended up selling it out of state.

I wonder if I had a duel setup, and when I was to smog it just run it on gas. I would think that I could get away with that. What mods havet to be done to the carb if any to do that.

I would go duel fuel if your worried about running out, then your covered.

Most of the stuff here in the UK is from Oz, Holland or Italy, have definatly seen mixers to suit a Toyota.

I run a Duel fuel Rover 3.5lt V8 in my Toy, I get better MPG on daily driving than petrol, a little less on long runs at speed. A little less power, but not worth worrying about for the money I save

Most motors that will run on unleaded will be OK on gas, Got the ignition advanced to about 25'o BTC, plugs opened up to just over 1mm and a good electronic ignition. It'll still run on petrol like this, its only for backup anyway.

We have found injection motors run nicer than carbed motors. If you have a o2 sensor you can run a 'closed loop' computer controller system to keep the motor constantly tuned.

The trick is to get the spark in hard and early, cos the gas is harder to ignite than petrol. My 6 month old oil still looks like new, people think I'm nuts when I'm changing it!

Sucks about your smog laws, cos a gas motor is rediculusly clean compared to petrol, and it'll run much better without a cat.
