I have a 95 Toyota P/U with the 22RE. I have an opportunity to purchase a 4.3 GM motor extremely cheap(the entire vehicle). It would require going through and overhauling. Has anyone done this conversion and what other expenses have you had to do. I need a little more power then what I have now. To be quite honest I favor keeping the original motor if I though I could get a reliable 150 hp out of it with upgrades. Any suggestions?

Thanks

a lot of work involved in a swap. but i sure like mine. was gonna go 4.3 untill i found out about the 3.4 and stay all toyota.
check out the engine swap section on yt. info on all swaps.

 

i have a buddy that has a 86 4 runner with the 22re.. he wanted to do the 4.3 and he got it in and couldnt figure it out nor come up with the rest of the funds to finish it.. he stopped junked the 4.3 motor got another 22re. and is now doing the 3.4 coversion.. the 4.3 is bad news. keep it toyota with the 3.0 or 3.4

 

3.4

 

A couple of my friends have done the 4.3 swap. they really liked it and it was a huge power difference. If you got time and youre getting the whole vehicle (definite plus because the wiring is pre hacked) then do a lot of research. You will really like it if you do.

 

High torque Cam, header, remover egr, maybe ported head in a 22re and you could be close to 140 ish maybe? All i know is i had a stock 22re and its was slow as hell then my buddy bought a built truck with what i just saif up there ^^^ and it hauls! Hills at any speed almost any gear too. I have done 50km/h or 30mph? Up and hill that took my old stock 22re to be in 2nd or 3rd reving it to hell were his built 22re can chug in 4th at 1000rpm and still excel up the hill. It beats 3vze's all day long.

If you want that extra power and dont want to deal with an engine swap then i would seriously look into mildly build on a 22re. You gotta remember that a 3.4 will need a different tranny, motor mounts, fuel lines/ pump, intake doesnt clear hood, wireing, exhaust exc... If u want that high hp torque 4.3 or 3.4 just sell your 22re and go buy an already v6 truck with a blown 3vze since there dime a dozen yay!

 

Its like you can compare the 3.4 to a 22re because you recently swapped your 22re out or something.

 

IMO, 4-cyl + truck/suv = fail.

4.3s almost all put out 260 ft/lb of torque, I went with the early CPFI version with 190 hp. It's a pretty sweet fit, a little snug in a few places, but I love it.

I have probably a grand into my swap, and my donor blazer was $40. That's with new timing chain, water pump, and some other tune-up parts.



4.3 swap has been done MANY times. Also, GM made the 4.3 for like 25 years, so there are a lot of different variations. I suggest setting down in a comfy chair, and reading everything you can find about these. There are hundreds and hundreds of build threads documenting the swap.

But, because the 4.3 was available for so long, and in so many vehicles, and was based on the 350 V8.....parts are CHEAP!! And you can walk into any parts store, anywhere, and they will have a lot of stuff on the shelf for it.



I have a couple threads here about the swap (In the domestic motor swap section, and the 86-95 build-up section) where you can see a lot of what I did and why. My build never really made it to the front burner, so it took a LOT longer than it needed to. So I'm just starting to test-drive it, but I'm very happy with the results so far. No welding done. I bought all bolt-on mounts, tcase adapter. Stock (toyota) driveshafts, stock (toyota) tcase crossmember, stock (toyota) radiator.


A coworker of mine has a tacoma with the 3.4, and that looks like a great engine. But they are much more expensive, and parts are too. I'm sure they're more reliable, but I'm not convinced that you'll make that back.

 

And no one asked...

Do you need it to be street legal?

 

Why is there boners all around for the 3.4? Its an awesome engine but if you're looking to swap I'd be picking up a 3rz-fe. You can keep your transmission, crossmember and a few other bits.

The 3RZ-FE is a 2.7 L (2,693 cc) I4 version built in Japan. Bore is 95 mm and stroke is 95 mm. Compression ratio is 9.5 to 1. Output is 150 hp (112 kW) at 4800 RPM with 177 lb·ft (240 N·m) of torque at 4000 RPM. This engine features twin, chain-driven balance shafts. It has four valves per cylinder and DOHC. Valve adjustment is by shim over bucket.

Exhaust and intake and you're good to go

 

Numbchux, I dont know what your smokin but it must be somthin good... but im pretty sure the 4 cyl In a small pickup was not a fail... LOOK HOW MANY PEOPLE DRIVE THEM.. the 22re is twice the motor the 4.3 will ever be.. 22re 5 speed all the way.. 4 cylinder pickup's rule..

 

By that logic, the 4.3 is a better motor, as it's far more common. Look how many people drive V8 half-tons without a trailer hitch. That's even dumber. If I just wanted something big and slow, I wouldn't have sold my lifted Subaru.


I have a trailer hitch and roof rack on my Celica for when a 4-cyl is enough. I'd like to be able to comfortably pull a boat, or even a car occasionally with the 4runner.

 

I checked out your 4runner. Look how complicated the swap was.. Takes alot of time, and aslong as you got the right gearing a 4 cylinder will do work.. I got 529s i can pull a boat.

 

Me Too !!!

 

You guys have different definitions of pulling a boat. I'm talking about 3k lbs at freeway speeds, with enough gear in the rig for a weekend away. .



It was a pretty straightforward swap, one of the easiest I've ever done (I've been involved in dozens of subaru swaps, including into multiple VWs, dune buggies, and even an RX7), certainly the best-documented. Would have been even easier if I had done the 4" bracket lift instead of a 2" body/drivetrain lift.

More power than the 5VZFE, cheaper to buy, cheaper to maintain, fits like a glove. Of course, the 5VZFE swap was not nearly as well-documented when I bought this truck as it is now, so it's a much more viable option, but I still don't think it holds a candle to the 4.3.

 

Can you SC a 4.3?

 

It's a very mod-friendly engine. I haven't looked into forced induction at all, but with the right management, I'm sure it could probably handle 6-7ish pounds of boost pretty well.

 

But not 9-10?

 

I would probably go with the mildly built 22RE, which is what Im doing to my truck now. If you want a 4.3 just get a Blazer or S10, you can pick a decent one up pretty cheap and their just about as reliable as the old Toyotas. I know because my family has had Blazers and S10 over the years and they all lasted a good ways past 200K. One family member has an '84 S15 4x4 with the 2.8 and 4 speed, I hope to get it and I plan on using it for my work truck and keeping the Toyota for the weekends, 4 wheeling, camping, fishing, hunting and stuff like that. (and pulling my buddies out of mudholes)

 

I run 9-10 with factory internals.

while the 3.4 is super easy with the 3.0 it take some work with the 4 cylinder. The easiest and best mpg way would be 3rz swap. Almost a bolt in deal.
