1989 4X4 22re to RET conversion?

1989 4X4 22re to RET conversion?
Hey all!
I currently have a 1989 5 speed 4X4 pickup with the N/A 22RE.
Guy nearby me is selling a 86-87 22 RET that came out of a Automatic 4x4 with the engine harness and I have a 5 speed 4X4 manual RET computer.
I was hoping to build the RET up so when i'm bored I could swap in the RET.
So the only diffrence between the two engines is 1989 vs 1986-1987, 22RE vs RET, and Manual 22RE vs Auto 22RET
Is this feasible? sensible?
is it just drop in the engine/harness and connect the ECU and away we go?
is the crank different between the Auto and manual?
My cluster is obviously different than the 86-87 trucks, but I have no OEM tach on mine which was the only thing controlled by the ecm on the cluster right?
Thanks!

Depends how you define sensible and feasible ??
Just do a 3.4 swap you will come out ahead .
I was going the 22rte route looked at the numbers Sold the engine went 3.4
All the 22RTE engines I ran very long the turbo housings cracked even though I did my best to keep them cool
If your going to do this you may as well plan on up grading the Turbo from the start
Like any swap your going to merge the truck harness and the engine harness because most likely it will not be just plug and play.
Some repin the connectors some splice in the different plugs.
Then if your lucky all the coolant hoses and air intake hoses are like new because they are long obsolete !!
Since I never saw a down pipe for the turbo aftermarket that most likely needs to be custom made.
As well as the rest of the exhaust system
where the $$$ add up is all the minor things that need fabricated.
Then what end results are you looking for ??
Lots of work and expense for very little gain !!
Just to have a 22RTE ?
If this is a long term project to keep you out of the house go for it .
Only you know if this project will meet your needs .

Your best bet one ECU front is to use a DIY PNP2 ECU which supports MAP so you can part with the VAFM and assoc parts making room. If I'm right its OK to use the current trucks harness, just add a vacuum line for the map to the built in ecu sensor. But I agree you have to decide how deep you want to go, with engine swaps being the cheapest.

what wiring has to be changed? Or “merged” as you said. I’m confused as to that part, when I have the ECU and harness, everything else on the truck should stay shouldn’t it?

Off the top of my head
Dash harness isn't PNP, vafm not the same, you have an automatic engine harness and a manual ECU, fuel pump and regulator, radiator, coolant piping and water outlets, pinion ratios..
You're gonna need to look at the FSM for donor and recipient, just like any swap..

got it, I see now, thanks for clarifying!
i have a friend with a 1986 Turbo, and our engine bays look the same almost. What are the diffrences between the 22RE and RET ecu’s. What happens if you pair a 22RET engine on a 22RE ecu? Im sure its not great, and smarter to do a standalone but im just curious.

Same thing that can happen when you run anything way to lean, bad things.
Thought you said you've used a tunable ECU before..
Sound like you have a lot of research and trial and error ahead, and/or gonna be paying someone lots of money..

i have a spare, similar size and internal wastegate turbo, that I had planned on sticking on it as it needs a new turbo.

Likely if the turbo failed it took out some engine bits also..
Assume it need rebuild or atleast a full gasket kit, weight that price versus your budget, usage and expectations.
The W series trans might not hold up, as well they out v6 sized differentials in the turbo ones..

Same size doesn't mean same specs, there are lots of variables there.

yeah it seems like everything i’ve been told is leaning away from doing a RET conversion.

In the end, it really comes down to what you want from the engine you put in.
Yes, other commonly swapped Toyota engines (2RZ, 3RZ, 5VZ) make more power naturally aspirated. If you are unhappy with the power your 22R-E makes, than one of these other swaps would be better than a turbo.
Any engine swap or build will be much more complicated than simply installing a straight replacement 22R-E. If you are working on a project truck and want to do a turbo conversion for the fun of it, knowing that it isn't going to make gobs of power, that is absolutely fine.
This turbo 4Runner is pretty awesome: https://www.yotatech.com/forums/f199...l#post52395476
In order to do a proper conversion, you will need to do quite a bit of research. Adding a turbo is not a simple bolt on procedure. You would need a Turbo ECU (or program your own), Injectors, and other turbo specific parts.
Like I said, it depends on what you want from your engine and having reasonable expectations of how it will perform.
Is there anything wrong with your 22R-E right now?

I'm not sure what that swap would look like, but the 3.4 swap peaked my interest, especially since its well documented.
No, nothing is wrong with my 22RE, its just tired. 340,000mi on it. So I started to think about contingency planning, and maybe upgrading.

In fact research will tell you the factory 22re is fine to run with stock injectors, stock pump and fuel pressure upto a point (from memory its some where in the 5-10psi range) then you start running out of fueling ability to keep things cool and not overly lean.. Due diligence is always your responsibility.
It really depends on what you want, expectations, usage ect..
Bottom line you need to do the math and research abit. All of it is out there with a few limitations (factory turbo maps you aren't going to find most likely).. Nobody wants to say "sure bolt a turbo to ..." And you come back "I melted xyz, thanks!! #$%&"

A conversion to mimic a factory turboed r series, yeah that's going to take some research. However I think I covered the large issues above.

Thanks for the helpful feedback. I'll have to do some more research in order to properly do a forced induction build.
