Toyota Truck 22R and 22RE Propane Conversion Kits
Toyota 22R Propane kits
Our kits are specially designed to bolt on carbureted 22R Toyota truck motors, and are designed to use your existing carburetor throttle plates. These are excellent propane conversions - very simple and clean. Most customers report back an increase in power! We test run and tune each and every one of these on our test truck to ensure the best mileage and power. Installation time should take 2 to 5 hours depending on your experience (this includes removal of your existing fuel system). There is little to no fabrication required. This kit has been designed by us specifically for this application. Beware of other kits claiming the same using much smaller components which results in power loss!!
20R Engines require the use of a 22r carb base and a 22r carb to 20r manifold carb adapter from L.C. engineering. This only applies to the 20r engine These are street legal as long as your local emissions laws allow it.
22RE Propane kits.
We now have a kit designed to use the E.F.I. engine. They are designed to run propane only. Lose that smashed up gas tank and poor driveability due to faulty sensors and old wiring with bad connections. It requires a carbureted distributor and ignition coil. It retains the stock intake manifold and throttle cables. It is designed to remove all of the efi wiring and sensors related to gasoline, resulting in two wires required to power the engine!
We usually use about 5 to 6 gallons if we run the truck non-stop all day. This is rock crawling/ trail running, about 8 good ones! A typical day of normal trail riding uses about 4 gallons. There is no loss in power with these kits, only power gains!! These are legal for road use depending as long as your local emissions laws allow it.
Note: These are not forklift kits! Don't be fooled by companies selling forklift kits that claim to be the same. Unfortunately this is not the truth. There are several very important differences that affect power and longevity. Forklift kits are equivalent to a one barrel carburetor!
Price: Price, $850 for the complete kit which includes tank brackets! If you don't need the tank brackets the cost is $820. Kit does not come with a tank. (has brackets for one tank). This is the price for both the 22R and 22Re kit. SHIPPING IS FREE ON THIS KIT!!
Possible Extras: Extra tank brackets available for $60

Our Suzuki Samurai Propane Kits are a dramatic improvement! This kit is the answer to Samurai carburetor problems.

This is the answer to eliminate the need to swap to E.F.I., which is a major project and huge expense. This is a major improvement to these vehicles. This kit also bolts on the 1.6 8 valve with the use of the 1.3 intake manifold. These will handle up to 100 H.P.! These are complete with everything necessary. It even comes with a K&N air filter and all internal components have been upgraded from rubber to silicone, easily doubling the service life of the equipment.
Once again I must warn people about other kits for these engines that claim to be the same. The equipment is half the size of what we sell and is not good for performance.

Dual Fuel Propane Kits for Carbureted V8 and V6 Engines.
Our Dual Fuel Propane conversion kit is for carbureted v8 and v6 motors using a standard 5 1/8 inch air cleaner opening (Most 2 and 4 barrel v6 and v8 motors) As well as carburetors with a 3 inch opening. They are designed to eliminate the need for a huge propane tank or worries about running low with a big motor. These are all mechanical systems with very little electronics. There is a switch that turns on either the propane solenoid or the gasoline solenoid. This setup mounts directly on top of the old carb. Keep in mind that this raises the profile by about 5 1/2 inches. The 3 inch carb adapter is 2.5 inches shorter. This kit does not tamper with any of the old emissions devices and is easily removable.
This kit is very popular for street conversions. It must be carbureted and local laws on smog vary from state to state. You would need to call your state to find out.
This is the same kit featured on Extreme 4X4 on the Spike channel.
These will handle up to 340 H.P.
These are NOT for late model, fuel injected motors. Carb only.
If you don't have smog, this is street legal.
