I'm new to the list and don't have a lot of time to browse back posts, but I'm wondering how difficult it is to swap a 3.0 V6 from an '89 4Runner into an '88 4Runner w/ a 22RE? What sorts of things do I need to do/have? Is there a drivetrain upgrade? I can get the entire v6 motor for $100 and wondered if this was a good idea or not? Also, does anyone know of a good web page for this type of thing? Any help or direction would be appreciated. Thanks! -C

You will need a bellhousing from a turbo truck (expen$ive), motor mounts, wiring, ECU, and potentially a new radiator, in addition to a bunch of other things that I cannot think of right now.

Sell your $100 motor to someone who really needs it instead of going through all of the grief and expensive for an extra 38 horsepower.

I have not seen a website documenting this and do not know of anyone who has performed this swap... and I think that says something right there. <img src="/forums/images/graemlins/mrt.gif" alt="" />

I say 3.4 all the way. Yeah you can put the 3.0 in there, in fact about a month ago I think I read a post on here from someone who did.(or the truck had it done when he got it, don't remember) However, for the expense and work put the 3.4 in, more bang for the buck.

I guess if you were in a situation where you had a donor truck and therefore access to the radiator, tranny, motor mounts, wiring, ECU, etc... and your 22re was blown, yeah that could be worth it. The 3.0 is a very tough engine. But otherwise, just search on 3.4 swap and see what you think.

Frank.

Actually, you need the R150 that came with the V6 I think, the W56 would not be happy behind that V6 for long even if you could find a bellhousing that would work. You could use a R151 turbo tranny but you'd still need the R150 bell housing (R series to R series). The turbo bellhousing would adapt a 22RE to the R150, kinda the inverse. Lessee, you'll need a hybrid clutch too. Not worth it. If you do it at all do the whole engine/tranny/tcase.

Here's another vote for the 3.4, or a chebie 4.3.

i agree... i think it wouldn't be worth your money to go that rotue.. but selling it to someone who just blew their motor.. somone on here just did.. for a fair price would be nice and you could put that money towards a 3.4 swap or a 7mgte.

best of luck


and welcome

Thanks for setting me straight Bill. I think that the W56 would like behind the V6 but I did not list the correct way to mate the two together. Like you said, one would need the inverse.

I think the W56 would do just fine behind a stock 3.0 V-6. (Getting it to fit, would be another story.)

The W56 is used behind the same 2.7 4 cylinder that is in the TAcoma on overseas Hilux. The 2.7 has the same 150 h.p./180 ft/lbs of torque output as the 3.0 V-6.

Fact is, the W56 would probably survive just fine behind the 3.4 V-6 as well. It's a strong tranny, you should see the torque it withstands in some overseas diesel applications. And I believe the Supra used a simlier designed tranny.

I was thinking of doing a 3.4 swap myself someday. But one cheaper and far simplier alternative is to get a complete built motor from Enginebuilder on this board. A new virgin head built is about $650 to $700 (can't remember for sure) and a basic stock short block is about $600 or so. Not a bad price for a motor that probably makes as much power as an LCE built engine. You won't be running anywhere near as much power as a 3.4, but you dont' have to worry about motor mounts, trannys, ECUs or wiring. And you'll approach the power levels of the 3.0 V-6. I think that's the route I'll go, when mine blows up. Got a while to go, though, it's still runs super strong even with almost 200K on it. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Interesting. I was basing my appraisal of the W56 on Dave @ Marlin's advice... my W56 is a little crunchy and I was debating swapping to a R151 instead of a rebuild, then being ready for the 3.4. Still seems like the R150/151 family is beefier than the W56, and you get a lower 1st to boot with the 151. Anywho... found a R151 and its sitting in my barn, but the darn W56 seems to have sensed its approaching funeral and it is shifting better! (maybe Redline MT-90 just takes a while to 'work its way in').

As unalterably cool as the 3.4 would be (and good mileage too!), I do keep thinking about Ted's motors. My Jasper will be very strong for a good long while, but Ted could set me up with a cool mill for a lot less than a 3.4 and I could sell some unfortunate soul a good Jasper motor. Can't modify the Jasper much, with their altered pistons, cam, etc. Its about the only argument I can think of against Jasper - if you change your mind about stock and wanna hotrod it, you gotta change the head. Forget the pistons.

Hmmm. A built Tedmotor. Maybe with a blower. Hmmm. Whatever, a R151 will be dandy, just needs a shifter slightly relocated and a 23 spline tcase input.

Bill did you see the modified shifters on Marlin's website. It looks like you could get one of those and would not have to cut any sheetmetal.

An Aisin tranny based on the W56 called the AX-15, I believe, was also used behind some 4.0 Jeep motors. But as far as the R series, I'm sure it's stronger than the W56. All trannies have a torque limit and I'm guessing the W56 is somewhere a bit north of 200 ft/lbs.

The R series is surely much higher than that. It's used behind some overseas applications that make as much as 285 ft/lbs of torque, so it's torque limit is probably well north of 300ft/lbs.

Interestingly enough, Toyota uses a transmission called the H150F for some of it's overseas Land Cruiser applications. I'm not sure if it's related to the R series or not, but I suspect not. I believe it's much larger. It's also used behind the 2UZ-FE V-8, in some of the base model Land Cruisers. Yep, Toyota actually puts a manual tranny behind the same V-8 that's in the Tundra on overseas models.

So, while the W56 is fairly strong, I wouldn't hesitate for a second to drop in a R151F in there. You'd be stronger, especially with the R151F T-case for sure. And I think you'd only have to switch bellhousings to bolt in the 3.4.

Just so I'm not totally hi-jacking this thread, I wonder why that 3.0 V-6 is so cheap. Remember that there are thousands of those engines floating around with leaking headgaskets and burned up valves. I think I'd steer clear of it.
