What would you have to change in an 1980 toyota pickup with the 20r and the 4spd to switch it to a EFi22r and 5spd?

 

You would need the computer and wiring harness for the EFI to make it all work.

 

that is what i was thinking but thought i would ask anywyas.

 

You will also need the throttle cable, fuel tank, fuel line (supply).

 

In lieu of a different fuel tank and internal pump, you could use the external pump available in some Toyota cars (my '84 Camry had one) and keep the stock tank. Just be sure to mount the pump as low as possible.

 

could you run a 22r off propane? how would you do this?

 

Yeah, lots of people do it. But its not street leagle. Not in California anyways, I dont know what the laws are in Washington.

I'm getting ready to yank my 3.0 for a 22r on propane. Its gonna be cool. I'm not using the got propane kit Its way to much money.

 

You'll also need to relocate the t-case x-member as the newer trannys are about 2" longer.

Gotpropane has all you need to run a 22R on propane.
