did anyone ever do this swap and what would have to be done other then remove the original 22re fuel pump. What about the wiring and can i re-use the original dist. with the carburated motor? need help, my original motor blew and got a 22r complete motor to swap in.

abecedarian

what year is the carb'd engine from?

algranger

The e-fuel pump is better either way.

If the carb motor is 85+ you can just put your efi intake and exhaust mani's on there.

You need to do some wiring for the fuel cut solenoid and electric choke.

BTW i've had many carb'd toyotas and you REALLY dont want a carburetor. They are inefficient, less powerful, harder to keep in good running order and they suck going up steep hills

abecedarian

If the donor is 85-95, it should bolt fairly well right in and use the 91's EFI intake and exhaust and most everything else just perfect with little, maybe 30-60 minutes work to rid itself of the carb stuff.

Remember, I put an 88 22R in a 91 22RE chassis.

the 22r motor i have on the side is an early 80's motor

i got another question abecedarian is the late 80's efi pickups the same engine harness as the 91 and up? talking about like the injector plugs and sensor plugs?

abecedarian

nope. late 80's 22re's have different harnesses than others. harnesses may differ, even if only slightly, from one year to the next, making it a gamble trying to use one in another.

but the longblock (cylinder head, engine block, crank and pistons) from 85-95 22r/22re should be the same. so if you find a block from the 85-95 range, you should have very few problems with putting it in your 91.

abecedarian

early 80's as in????

i need to go carb on my truck i tossed the whole 22re i figured i had a complete rebuilt 22r and didn't need any of the old parts. so how can i make this work on my 91 now? with all the plugs and sensors also will the e.c.u pull a check engine light?

kauai_toy91

84 i think

abecedarian

you'd need a lot for the 84 22r to work with the 91 harness.
first off, the 91 harness has plugs for the 22re sensors which are different than the 22r and are in different locations than the 22r.
second, the 22r uses a different distributor setup than the 22re, the latter being completely electronically controlled and the former having vacuum advance / retard, so different igniters and electronics to deal with that.
the 91 ECU is meant for EFI so it won't work with carbs
you'd need an 84 ECU for the electronic ignition....

should I go on?

kauai_toy91

so you mean to say i need to convert everything to get it running right? what about just to get it running and atleast have power to go around? what can i do? and wouldn't the dist on my old motor fit on my 22r carb?

abecedarian

like I said, the 22re uses the computer and igniter (to an extent) to alter timing advance and the 22r has vacuum canisters on the side of the distributor to accomplish the same thing. the 22re computer also controls injectors and such and measures coolant temp, air flow, and other things that the 22r doesn't.

stop and think what you'd need to convert from carb to efi- you're going to have to do the opposite since the RE stuff is gone (right?).

kauai_toy91

yea, im new to this so i dont know much im just going with what ever i got

Mine has a carb, and its a turd going uphill. The people behind me get very impatient. It will be interesting how it runs in the sub zero temps it will experience this winter (trying for a job at one of the ski resorts).

I'm about to do almost the same thing. My truck is a '92 with a blown 22RE and trashed EFI. I've been looking for weeks for an air flow meter, thinkin I'd build it back to EFI. My problem is where this truck will be going, it has to be reliable. Some of my fence lines go into prairee land where snakes, coyote,boars, bears, etc, hang out. So, I fear the elder electronics.
I think there's a workaround,but haven't got it all nailed. I think you can use the RE ignitor and distrib if you get power to it. You wont get the advance/retard though. I noticed the '83 dist has 2 wires also (but different connectors) so maybe the vacuum dist could be mated to the later igniter. You'd want to use/fit your later sensors to the early block for oil, temp, etc..tie off the EFI wiring for possible later use.
Still working the bugs in wiring, for me it's worth the effort. I'll check back to see if anyone else chimes in.

mudwump

OK, the '85-'95 igniter does work with the vacuum advance distributor (I am told). Your '91 sensors (oil press, temp,etc) should be mounted/adapted for gauges to keep harness/wiring issues at a minimum.
You'll need to find a choke hot wire (Duh) and plumb vacuum as needed.

My crank and rods are in the machine shop gettin resizing by my pals, in a few days it'll be built and plunked. I'll have more then.

I think I will look at mounting the reluctor and amp from the RE to the R dizzy for compatibility issues, the RE stuff seems stronger. You should use the R vacuum distributor as there is no advance/retard in the RE dizz (computer required).
