Has anyone ever change a 22re motor in a 1986 toyota 4runner to a 4.3 chevy block? If so what transmission and what would be the best set up?

 

I think people most commonly use the R150F trans with an adaptor plate to chevy motors, either 4.3 or 5.7 V8. Or R151F if you want to keep your 4cyl transfer case which is better, but good luck finding one of those. But you can still get an adaptor plate to keep your 4cyl T-case on the R150F.

 

my brother is running a 84 ex cab with a 4.3 700r4 np205. all chevy drivetrain with toyota driveshafts and axles. he hasent broken anything YET and wheels the he!! out of it.

If i were you id find a wrecked s10 or blazer 4x4 with fuel injection and get the entire drivetrain and wiring including fuel lines and tank with pump. Prob find one for around a grand.

IF YOU WERE TO PUT A GM POWERTRAIN IN A TOYOTA.

I myself like a toyota powerplant in my toyota (coming from a gm guy)HAHA!

 

I like were your going. 3.4

 

A 2.7 would be a considerable gain with fuel mileage, i am a poor middleclass homie that likes putting $10 every few days..

 

Yep.....been done a few hundred (thousand?) times. So many times that it is possible to do it with entirely bolt-on parts (only welded part on mine is one exhaust collector).

Have a look around the internet. It's been documented, you could (and should) read for days on this setup without asking any questions.

Also, the 4.3 has been in production for almost 30 years. So if you want any helpful information....you'll have to be slightly specific.

 

Ya it would be a big gain in power and mpg, but 3.4 is even more power without getting any worse mpg. Maybe a tiny bit depending on how your drive.

 

Im not saying you shouldnt go 4.3. After all toyota used them in some of their forklifts.

tiny bit?? no way jose. 2.7 dominates a 3.4 on mpg

 

Tiny Bit is correct. How about 1mpg diff I even gave you the 2.7 manual up against the 3.4 auto. For the lay person im showing the most fuel efficient combo for the 2.7 and least for the 3.4.

Preach on brother!

 

i did a 2003 chev 4.3 and l60e tranny and aa kit to a toy gear transfer. into a 85 x cab yota. need a body lift and to notch the frame if you use the stock headers on the drivers side. also pound in the firewall just under the acell petal.
wiring is simple (compared to other swaps)
ecu might need to be flashed to get rid of anti theft crap etc....

I did a 2.7 and love it. But my truck was a 22R originally. Complete bolt in, easy wiring, did it all myself in my driveway. Exhaust and intake are opposite, so custom exhaust is necessary. Mileage is exactly as stated above by Thatguy. I also have an 88Runner and it'll get the 3.4.

2.7 3RZ bolts in place of a 22R(E) with Chilkat mounts. 3.4 5VZ bolts in place of a 3.0 3VZ. Putting a 3.4 in a 22R(E) equipped truck requires relocation of motor mounts and crossover pipe reversal.

I'm a diehard Toy powerplant guy, so I don't believe in domestic contamination....

 

I can't help but ask why the 4.3 is such a common thing?? My zr2 had head gasket problems manifold problems injector issues, computer issues, it was the biggest piece of turd I have ever owned. My dad has a 98 jimmy and same thing, constant leaks and same issues, along with plenty of my friends having the same thing.

Am I the only one???

 

Cause there are litterally millions and millions of them out there

And more millions

 

They're not the greatest motor ever (yea yea...far from it, in fact). But they're not as bad as most, and they're cheap. I got an entire running donor truck for $40, delivered. And I can walk into any parts store, and buy just about anything for it, and parts are cheap, and plentiful. And since it's based on the 350, the timing chain and water pumps are interchangeable with those. I got a heavy duty water pump for peanuts.


In my experience, the only common problem is the spider injector thing. Which sucks, but it's common enough that there are repair and retrofit kits readily available from many sources, and it's easy to diagnose.




I would have loved to have gone with the 3.4, I think that's a much better motor. But I guarantee it would have cost 2-3 times more to do, and when something goes wrong (Yea...a lot less often, but you know it'll happen), parts are scarce and expensive by comparison.

The money I saved on the engine swap will pay for long travel IFS, finishing my FJ80 rear axle swap, and probably the extra fuel cost to use it. That's a no-brainer, if you ask me.

 

Which would be a simpler and cheaper swap my 86 22re to a 350 or the swap to the 4.3?

 

I would like to second RJYota's question. i know 350 would be a tight fit into an ifs truck, but wouldn't a 4.3 be just as tight(height wise) since they are the same design minus 2 cylinders?

 

I am also curious about this swap. I have an 84 22r and I have to have more power. Does anyone know of any build threads that cover this swap in detail?

Also is there a significant difference in mpg versus the 350?

 

I knew someone that put a 350 chevy motor with a turbo 400 trans in an old chevy luv. It also had jeep 4x4 front/rear axles & transfer case, jacked up to the sky. It depends how far you want to go.
