toyota_nick23 OK so this may sound like a repeated question but I'm not an electrician and can't seem to grasp the 5 main wires that make the 22re conversion so easy I have everything out of a 94 I just need to know the 5 main wires that everyone says you need to make the engine start?

toyotatime I would look at the tanks from 2nd gen EFI ext cab trucks, I would think they would bolt right up. I started with a modded carbed tank in my first gen, like Provience is talking about. The problem I ran into was when I got down to my last 3-4 gal of gas and went around a corner the engine would cut out for a second. What I learned is that EFI tanks have a pan in the bottom that stop the gas from sloshing away from the pickup tube and carbed tanks don't. I found a stock efi tank from a 90's 2wd truck was a bolt on for my first gen and it solved the cutting out issue.

Provience I used my stock carb'd pickup gas tank and just cut out and mated the fuel pump/return line mounting ring and bracket to it.

Ever so slightly more work than just swapping tanks, but it was worth it in my opinion. The 4runner tanks hang down lower under the frame to accommodate space for the rear seat mount and foot well. My stock tank already sees enough abuse, hanging down another couple inches would NOT work well

Remove both tanks, Clean/wash out and allow to dry, light torch and 'poof' out whatever little bit of vapor may be left (if you die, don't blame me) the use grinder/drill/saw to cut out a square around the mounting ring. Be aware that the mounting ring IS DIRECTIONAL.

Cut out slightly smaller square to allow access for pump in carb'd tank, clean out and rotate to discourage vapors, weld the new mount on top of the old tank. DO NOT WELD A SEALED TANK. make sure the fuel pump is out so that it is an opening, just in case. That way if something minor does go pop it will have a place to vent and pop out instead of trying to rupture the tank.

Gas tank compatibility

anybody know what gas tanks can work for which vehicles?
I have an 86 ext. cab carb'd pickup truck. I bought an 87 fuel injected 4runner with running 22re. My plan is to swap the engine and electrical into the pickup. Im stumped on which gas tank I can use. 4runner gas tanks fit in pickups? If so is it only single cabs or will they fit in ext. cabs as well.
Thanks in advance.

82twistedtoy Going crazy with my r to re swap I have a 83 truck, bought a 2gen truck 22re motor motor harness and dash harness (dash harness was cut in 2 spots) i got a non cut un known year dash harness from a friend and have hooked up everything i bypassed for my fuel pump for I have a sheet metal dash I still use my key for accessory power but im not getting any spark to my coil don't know if I'm supposed to run another wire for key on power to ecu? Because power runs straight to the coil on 22r motors and not through the ecu? have a yellow plug ecu if that makes a difference? saw this question earlier in the post with no answer.

turbosupraforme I have an 83 block with an 86-95 head on it. Found out that it was an 83 block after buying a complete engine rebuild kit including brand new head. My truck is an 86 efi btw. The timing covers are definitely different and aren't interchangeable and its a clear difference in deck height. I had dome top pistons and my kit came with flat top pistons and I tried the dome tops and the head wouldn't fit so I had to put in flat tops and fit great. I am leaking oil from the oil pump seal so I really think that the 86-95 pump isn't interchangeable. It builds pressure and looked exactly like the old one tho. For some reason we couldn't get the timing cover back on after installing engine back in the truck without taking the head off too...it was a tight fit. I had a ton of problems but it worked and I have already ripped both of my bumpers off taking lil red offroad lol

22re swap exhaust question

New here but have been on the mud site for a few years with my 40. I recently put a 22re in my 81 pickup (4wd) and now need to get the exhaust up to inspection standards as my registration is due. I put in a 94 22re and the 81 exhaust bolted right up but there is no place for an o2 sensor and the rear part of the exhaust is on its last legs. Does anyone know if a complete exhaust (down pipe, cat, muffler) bolt into a 81 truck? Minor mods or not even close. Thanks and I will post some pictures when I figure out how.

Yeah it is all documented either in the bible or in this forum. Well you are going to need to add holes and drill stuff if you want to use a hydraulic clutch all factory style, the wiring is straight forward, just need to bypass the neutral safety switch in the harness.

can I pick your brain a bit more?

Provience You will be better off in the long run if you don't bypass the CSI. Also, those wires are pretty damn dirty so good luck getting somebody to tell you what color they are from those pictures

Multimeter: will tell you where they go.

Pull that joker apart and start tracing some wires. Keep reading those two links posted earlier up there

ndubyota Connected black wire with black with yellow wire now have power to things. What are the other wire colors and where do they go?

maf tested!

So tested the maf and its good however my fuel pump is not engaging neither is starter when turning ignition. So that's the next roadblock! Don't forget I'm still trying to figure out what this 9 wire plug is which I will post a picture as soon as I figure out how to exactly. And no power to cold start injector so now reading through some forums to figure out on bypassing? Thanks a bunch!

The 84 and 89 sensors have different resistance values and plugs. So no?? I think is the answer

example, the 84 uses external resistance for the fuel injectors and the 89 does not

Read the above thread and check out a Factory Service Manual. You could have any number of issues but really we'd need a better description. The FSM should provide you with everything you need to test/inspect all of your sensors to make sure you are within operating tolerances.

Timing? Intake Leak? Fuel Injectors? Grounds? Wiring? Neutral Start Safety Switch?

Shameless plug https://www.pirate4x4.com/forum/toyot...-diagrams.html check out this thread if you want an easy/stripped version of a 22re wiring schematic

Do you have to worry about SMOG or are you just trying to wire the engine in separately "buggy style"?

I can't remember off hand if the '84 head (assuming it hasn't been rebuilt) has all of the intake manifold holes pre-drilled for the EFI manifold.

If it does, then just read this thread a couple time and swap the manifold on to your good long block and install it using all the EFI stuff in the same fashion that your old engine was hooked up. Your truck is already wired for it, you aren't really doing anything more than a longblock swap.

If your head is too early for EFI bosses and you don't want to make an adapter plate, then sell the 84 22r and buy a newer style or rebuild your 89 block

toyotatime My RE harness is spliced into the original 20r dash harness. All my original gauges,etc work as they should. Looking back on the 22re swap I wish I had gone 3rz but RE beats carbed all day long.
10-02-2014 09:18 AM
MT4Runner You don't need the dash harness, but the ECU does need to see a resistance on the charge light circuit.

Use the dash harness if you want the gauges to work; if you're buggying it, you don't need it.

Donovan91 is there any info on swaping the whole motor and harness's from an 89 22re in to an 81? haven't really seen any info on here, i know i need alot of stuff from the re but i don't understand what needs to be wired and if i actually need the dash harnes
