Toyota pick up/4runner 80s 22R

[hypertek]

Has anyone done the 22R toyota pick ups/4runner ? Im looking at selling my blazer for a 84-88 toyota truck or 4runner 4x4. I know with lifts and bigger tires really affects the mpg, just looking to squeeze the most mpg if I get one. I didnt find too much info on them..

Also the 84 model is carbureted, 85 introduced efi.

Does it have an O2 sensor? This is important some 1984's especially California ones did.

Yeah i believe they do and have maf sensors on the 85+


I dont know about 84 if it has o2 sensor, but has the carburetor typical round air cleaner

I have an 84 with an O2 sensor and a carburetor, that is why I am asking. Two different ways to get good results from the same 22r. The 02 sensor is located right where the header and the pipe joins. You can't miss it if you have one. Everything else looks exactly the same. Let me know.

oh ok, did you do an hho setup on it? Do you have any threads about your setup?

I am really looking forward to trying to pick up a lifted 4runner, just whatever year I find and wanted to see if gains are easily doable or if doing o2 spacers and efie things need to be done.

No threads on my truck. Any of the 22r carb version without the 02 sensor have been able to get 35 to 40 MPG. The fuel injected ones get about 25% to 30% gains but require an EFIE. At least that is my experience or information from some one I know. Every car has its own challenges even if they are brand new. No two work exactly the same. There are other things like water injection and the use of negative ions/ozone and other methods when combined with the HHO get you well over these figures. Just depends if you want to futz with it. The more you do the more you get. LOL My truck is all experimental and the data would not apply. I can say this it will pass all gas station in a 630 mile run easily.
