Flip the numbers around: 4.3, there, now that would be a better swap, IMHO. <IMG SRC="smilies/biggrin.gif" border="0">

Someone on this board with a 1st gen 4Runner did this swap but I haven't heard anymore about it or seen any pics of it. I think it would be a sweet swap, with the supercharger being available and all. As to the comment about putting in a 4.3 instead, all I have to say is if I wanted an american engine under the hood I would have bought an american truck. <IMG SRC="smilies/puke.gif" border="0">

Fine, spend twice as much on a 3.4 swap then, it's not my money! <IMG SRC="smilies/biggrin.gif" border="0">

There are many things to consider when doing an engine swap: cost of new engine, cost of swap conversion parts, ease of swap (AKA: how many people have done this in case I get stuck on something), cost of go-fast goodies for the engine, cost of regular maintenance parts, availability of parts.

I would rather have to try to find parts for a Chev 4.3 when I'm in the middle of nowhere!! I have a Taco with the 3.4, and I love it, but I would not spend big bucks to supercharge one, and put it in my 'runner.

Everyone says they cost more but I have seen them as low as 900 for a complete 3.4 with computer.. I have seen trannys and 3.4 motors together for 1200-1500..

That seems pretty cheap to me..

add in some custom brakets and a radiotor a conversion for the transfer case avaible threw marlin (last I checked) and your set!!

4.3 would be ok, but I didn't buy a toyota to have it break down like a chevy..

Just my 2cents!

Ya right, not a damn thing wrong with a 4.3, tried and true engine IMHO. Chevys are american Toyotas and Toyotas are Japanese Chevys. I own both, and the chevy is at 170K and still runs strong, no leaks, no burn'n the oil

Either one would be a good swap, better than the Toy 3.0 or 22r(e) by far. Even the 2.7 4 is a good canidate!

And then there's goig with a V8, nothing badder than a clean V8 swap! Just ask Brandon!

i've just done all the research, here goes, need an engine, wire harness, mounts, computer from a 3.4L then you need either the tranny from a 3.0L or deal with other difficulties using 3.4L trans, gotta buy or make an adapter from www.inchwormgear.com or Marlin, then gotta move the battery to the other side of engine compartment, then gotta buy a k&n filter set up for 3.4L so you don't have to use the airbox from toyota, figure out all the wires etc, oh yeah use a 3.4L pickup radiator.. i've got a ton more info on this as i will be doing it to my 83 p/u soonish. email me here if you want more info.

i had an 84 xcab toy w/ a custom turbo charged 3.4 stuffed into it. You can find the motors cheap, but your better off finding a totaled truck. There is also a guy at San Bernadino Toyota that did the swap on his 86 runner. There was supposed to be a writeup on 4x4wire, but dont know if it ever came up. The topic was also covered here about 2 months ago.
I also have a 2.7 Tacoma motor, puter, etc...still sitting in the garage awaiting to be swapped into our 83.
You cant use a 3.4 radiator for the swap, use a 3 core from an autotranny 88-95. Only marlin sells the adapter to keep the passanger side diff. or keep the stock t-case, a marlin for the tacoma, and pick up a reverse cut ford diff.

Your right about the 4.3 being a good engine, it's just all that other chevy crap that bolts on I'm worried about <IMG SRC="smilies/biggrin.gif" border="0">

Plus, with the 3.4 can you say SUPERCHARGED <IMG SRC="smilies/usa.gif" border="0">

Don't see how this would be any more expensive than a chevy swap... assuming you can fabricate the engine mounts yourself.
My 4.3:
Van w/ 4.3: $500
Wiring harness w/ Speed Sensor delete: $475
Tune up: ~$120
AA Radiator: $350
Exhaust manifolds: $150
Exhaust: $200
AA RF150 Bell housing: $300
AA Flywheel: $300
AA Pilot bushing: $40
Clutch/disk: $150
Misc hoses, etc: $200
Motor mounts: free.

So, that's over $2500 to keep the manual tranny. If you have a V6 already or a 4-cyl turbo, the only thing you need is:
Engine
Edelbrock Headers (or another header that dumps on each side)
exhaust
motor mounts
3.4 radiator
wiring......

To me, this sounds much easier than the 4.3. I'd do it in a heartbeat.

I can't really argue about the motor.. I was basing my opion of it based on all Chevys.. I do know the 4.3 is a very nice motor.. I just my self like to stay true to the toyota name...I also think it would be cool to have a new motor in an old truck... I see chevy swaps all the time in L/c's..

I can't wait to see a Tundra v8 in a older toy or L/c.. That would be cool!

It's killing me to put a dana 44 on my taco instead of a toyota axle, but I just can't justify the cost of a hybrind toyota axle, and besides there's the whole diff and cost thing..


Latter!

Dont waste your money on the K&N. Most 3.4 Owners have found that it does more harm than good, and shows little to no gains at all. For info on 3.4L Tuning check out www.gadgetonline.com

hought about this swap, and the power doesn't add up. i mean...you can easily get 300HP out of a naturally aspirated 4.3, but you have to SC a 3.4 to get like 250-275 or whatever it is. then you'll really need bigger injectors and some computer work to get the torque and HP you're looking for with the swap. then you have to fab your own wiring harness made up of the stock and the 3.4 taco/4runner harness and computer. for the 4.3, all you have to do is call painless wiring, and buy a wiring harness. it's a lot easier and cheaper for the 4.3, but if you want to do a 3.4, then good luck. also...if you want a supercharger, SC a 4.3 and you'll be looking at like 400HP. 4 wheel burnouts are not a bad thing <IMG SRC="smilies/bender.gif" border="0">

Have you looked into doing a Supra inline 6 cylinder swap? The non-turbo 7M-GE is about 200 HP stock, and the manual tranny bell housing on the supra is a direct bolt-on to the truck/4runner transmission. Motor mounts, fan, radiator, and wiring are still issues, but it's like that with any motor swap.

"Everyone says they cost more but I have seen them as low as 900 for a complete 3.4 with computer.. I have seen trannys and 3.4 motors together for 1200-1500.. "


I am curious where you found a 3.4 fot 900!

He didn't say that he was looking for HP numbers like that. And you're going to lose reliability and ease of maintenance if you're getting 300+ out of a 4.3. The SC on the 3.4 is super reliable and if you only want 250 hp out of it there isn't anything special you have to do like upgrading injectors, MAF, and increased exhaust or air flow. Plus Toyota thinks it's reliable enough to maintain their 7yr/100k warranty. I'd like to see Chevy offer that on a 300hp 4.3.
