I'm getting ready to pull my motor and give it a good overhaul. I'm at a point where I'm making my 4runner a backup vehicle/hunting truck instead of a daily driver so that I can take my time and really get this thing running good and keep it running good.

I've kicked around the idea of putting a carb on the motor and eliminating as much of the emissions stuff as I can. It seems like this could make for a much simpler motor to work on. Has anyone tried this? I have read the emissions elimination write ups. There seem to be mixed opinions on that. I have not found much info on putting a carb on a 22re to eliminate a bunch of the electronics. Has anyone done this? Any good write ups out there on simplifying a 22- RE?

Thanks

 

You will spend more time converting the 22RE to a Carb, it's not a easy as simply throwing a carb on there.

You will need a new intake manifold, Dizzy, ECU, Carb...etc.

The emissions are not hard to deal with. You can eliminate it all and the truck will still run fine...

 

I wouldn't do it. Diagnosing problems with the 22re is easier. IMO.

 

Keep it EFI. Most EFI problems are bad connections. Once I bought an EFI truck for hunting I will not go back to a carb.

 

It is hard for me to understand why anyone would think a carburetor is "simpler" than any fuel injection system. An EFI system can have its demons, but carburetors are clunky mechanical systems that are a pain to adjust (look at a manual; bend this rod a little, try to set this plate at 12°, etc.)

So I agree with the others; stay with EFI. I'll go even further; keep all the emissions gear. It's not hard to keep in working correctly, and you don't really want to smell up the woods, do you?

 

I own a carbed 83 and a EFI 94.
EFI is much better much much much better. SO much better I have seriously considered doing an EFI swap into my 83. If I had the 15 hole head it would be done by now!

 

*"like" all the pro- EFI responses*

 

Carbs are long obsolete.
Happy to have EFI and never looked back.
Computer managed fuel delivery, along with vastly improved lube oils,
has had the largest part in making our 'Yotas into the near half-million mile machines that they are.

 

Ok, thanks for the responses. It looks like a unanimous "keep it stock". I guess with the motor out I'll be able to clean up all the electrical connections, grounds, and vacuum lines and hopefully get a better understanding of how it all works. The reason I started down this road was because I bought an old F-150 with the "straight 6" and really loved how open the engine compartment was, but I guess dealing with tight spaces is just part of owning a 22re.

That being said, the big job I need to do is a head gasket and have the head inspected. Would you all recommend leaving the motor block mounted to do this repair or going ahead and pulling the motor so that I can get to all of the gaskets easier while I'm at it? Thanks again

 

Tight spaces? Try working on a 3VZE! I've learned to contort my arms and wrists in ways I never thought possible. Those open engine bays are a thing of the past, unfortunately.
