another 3.4 swap, 89-99 plus auto T-100

[panty dropper]

Here is what I am doing right now to keep busy, My 89 pickup used to be a 5 speed 3.0 4x4, but now Its gonna be equipped with a 3.4 out of a 99 4 runner and an auto trans and wiring harness out of a 1995 T-100. Now you might ask, why such a wierd combo? Well, I dont have the money for the adapter to make a taco auto tranny fit my truck, but a T-100 has a right hand drop transfer case and a 3.4 from the factory. I got the engine straight across for my 3.slow, I work at a toyota junkyard and the 3.0 out of my truck sold for more than the 3.4 is worth, but I stole the tranny because I am the manager its what I do.

Here is a pic of the truck I took the engine out of.

here is some pics of the 3.4 oil pan as compared to the 3.0 oil pan, you must re-use all 3.0 oil pan/pickup tube and baffle spacer plate.

The old front dipstick will have to go, I used a 1/4 inch pipe plug that is used for oil galleys on small block chevys, along with a dab of silicone.

Here is the devil This little bastard took over 1 1/2 hours to get out of the T-100 block, you must use this little adapter and dipstick tube from the T-100.

here is the new oil pan on the new engine, note the motor mounts, they are direct bolt on's from the 3.0, all the way up to the block down to the rubber pads, the 3.4 ones were 100 percent wrong. Some guy told me they were the same and to just drop it in my truck, that would have sucked.

Here is a pic of the bad 3.4 out of the T-100, it ran but it smoked, I had to chenge everything off the T-100 engine to match the 4 runner engine, Injectors, middle and upper intake, every acessory on the engine was different from the 99-runner to the 95 T-100.

Here is the 3.4 T-100 Tranny and transfer case to get an idea of the size, It is actually only 1/2 inch longer than a stock 3.0 truck or runner auto.

[panty dropper]

since it is recommended, and I like body lifts because it is easier to work on, I went with the minimum of 2 inch body lift from performance accesories, half the bolts were the wrong length and the bumper brackets really suck, I wouldnt tell a friend to buy that brand.

This part was fun, that plate didnt fit worth shit, I had to "massage the firewall" to make it fit and silicone it up to make sure it was not gonna leak.

And here is the empty engine bay.

Nice and clean and sexy, I know, but I had to have the engine and tranny set in and out of the shop in 4 hours then tow it home like that The owner of the shops wife is a Cunt with a capital C. Said to get it out of the shop since it doesnt belong to the company, oh well.

[panty dropper]

Got the engine in the truck, took all of 10 minutes to lift it up with the cherry picker, lower it in and bolt up all 4 motor mount bolts to the frame, and probably 45 minutes to install the tranny from underneath with a tranny jack, arent lift racks magical?

[panty dropper]

Notice the middle pic in the last post, the steering shaft rag joint actually hit the alternator, I tried a smaller belt, no go. The closest was 1 1/4 inches shorter and could not go on. The body lift also came with the rag joint spacer that just happened to make everything fit pretty good there.

It is very very tight at the driver side of the engine, it hits the passing gear cable and the dipstick is supposed to go there too. Maybe a aftermarket flexible dipstick tube from jegs or summit will fix that.

Here is some side shots of the engine in the truck.


The wiring harness went right into the firewall like the stock one, the taco and 4 runner have a odd shaped plate that mounts with two bolts, the T-100 has a regular old truck style push through.

Yo,
Sweet...get ready to sawzall the hood for intake clearance.

Hope that 3.4 doesn't blow that POS A340H transmission.

Keep us posted with the final results.
Rock on,

Just posting so i can get auto updates to this post.

[rockota]

why replace the R150 with an auto??????

[panty dropper]

The 340h is supposed to be a good tranny from what I have heard, my 5 speed had the syncros going bad, 1-3 gear were a bitch when it was cold outside, and I really dont like shifting, there I said it. I drive a tow truck most of the day with a 5 speed and a powerjoke diesel, the last thing I want to do when I get off work is drive a stick home. And the wife refuses to drive my chevy pickups because the camo and mud are embarassing and the pete jackson gear drive pisses her off, and the other is too tall, she is afraid to drive it. So this truck is going to be something she can use to haul stuff when I am not driving it.

I have driven a 98 4 runner with a 3.4 and an auto and it would have beat my 3.0 5 speed truck any day, and the runner is heavier to boot. We will just have to see if this works ok, then I will know if I want to do a similar swap into the 84 4-runner I have.

2 inch body lift fixed that already, fits perfect with the hood closed, everything looks stock from the outside.

[mxmw54]

exhaust??? i want to do the exact swap, so far what i need is 2 inch body(already have it) steering spacer(check)
harness
engine
i didnt really understand how the dipstick deal works out.
what crossmember?? and does all the cooling stuff(radiator, fan hoses) work off of the 3.0 or use the 3.4 stuff or aftermarket?
back to the exhaust, can you use the 3.4 exhaust? or go After market for that?
this thread is kickass keep up the good work.

The dipstick for the engine has to be on the side of the block, because when you install the 3.0 oil pan on the 3.4 the dipstick itself wont go in the tube, it hits the pan as soon as you try to put it all the way in, if you do the same swap with a good T-100 engine, then you shouldnt have to change the pan or dipstick at all. The T-100 was a midsize pickup based on the regular toyota, not similar to a tacoma at all. The T-100 shares a lot of chassis parts with a regular 89-95 toyota, its just wider. The cooling stays all 3.0 as far as I can tell, my radiator is almost in, Pics will be added when I am done, and the exhaust?? I dont know yet either. I brought pics of the engine out of the truck, pics of the offroad solutions 350.00 dollar crossover pipe and the stock crossover pipe and my exhaust shop said "we dont want to run the crossover system, its too close to the cab, we will run duals out the bottom or make a crossover if we have to, just put the engine in the truck and drop it off and we will fix it for 200 dollars either way"

I looked under there, good luck with the dual exhaust. I am thinking crossover either way, to re-direct it down the driver side.

Crossmember is not done, or started yet, pics will come.

I got a few small things done today, that whole life thing always slows down projects. I got the brake booster hooked up, the newer toyota's have a check valve on the booster itself, and my 89 has the valve in-line in the hose, so I bent the nipple on the booster straight so I could install the line and check valve and still have it look stock.
I also got the cruise control just about done, The V-6 cruise cable is very short, so I wandered around the junkyard A.K.A work and came up with this, the 4 cylinder fuel injected trucks have a very long cruise cable. I was going to swap out the entire cruise assembly but they actually look a little different and the parts all have different numbers on them and the 4 cyl unit is all black and my stock one is all gold anodized, the other would have plugged in if I stretched the wires, but I opted to just swap the cable off the 4 cyl unit, just easier and I know it will still work as it did with the old engine since the cruise is not controlled by the engine ecm, it has its own brain wired into the body harness.

[panty dropper]

Now for the pussy stuff also known as air conditioning. I really hope this helps someone else in the future. I tried a lot of shit over the last three days and finally got the ac hooked up. The new 3.4 engine has a R-134A ac system, and all toyota's with this setup from 94 1/2 -present have bigger ac line fittings on both ends, evap and compressor ends. I thought, ok get the evap box out of a 95 pickup, its different a little but would work, ok. Nope, the lines coming out of the box to the condensor are wrong too, and if you took every part ouf of a 95 (the parts are 95 only) you could bolt the lines into the truck. I dont like having one year only wierd shit on my trucks not to mention very expensive and of the several hundred toyotas at my shop, not one has a good condensor, basically if a yota isnt plowed in the front, then its not totalled enough and a gypsie car dealer will out bid you at the auto auction.
Here is the pics of the 3.0 bracket compared to the 3.4 bracket, the 3.0 has v-belt pulley.

also here is the different style of compressors, the 89 3.0 comp is far left, the 92 3.0 comp is in the middle, the 95 3.4 is far right.


I did some looking and was told to use the stock 3.0 ac comp on the stock 3.0 bracket on the 3.4, it would have fit like shit and you have to change the ac clutch off the 3.4 comp to the old 3.0 one. I broke three ac compressors trying to do this, if the clutch doesnt come off with a tug, then it isnt coming off, is should just slide off.......ask me how I know. To get the first part of the clutch off I did this, take out 10 mm bolt, thread another toyota bolt with a 12 mm head into the threads in the clutch and thread in and it slides right off.

then remove the snap ring and slide the rest off. All three compressors seemed to bolt right up to the 3.4 bracket, not sure if the length would have been an issue or not, since I came up with something better using my man sized brain Looking at the compressors on the bench I thought, man the intake/exhaust manifold on the compressors look very similar except where the hoses bolt up.

Guess what.


That sumbitch went right on from the old compressor to the new one, and all my old lines bolted right up, so not only do I have a R-134 friendly compressor, it is still a common part off a T-100. Its been holding for 2 days now, still has pressure, I am pretty happy how it came out.

[panty dropper]

Also got the power steering lines all hooked up, the low pressure side was no big deal, cut, bend to your liking, easy. The pressure side, I came up with this. The 89 hose has a thinner fitting on the end so the 3.4 bolt that holds the banjo fitting on is too long. I used a 3.0 pump banjo bolt and it seems to be working fine, I massaged the hardline a little where it comes out of the compressor just to make it fit a little better (I am a little anal on small details)

So far the only issue is losing the steering valve??? whatever this does, the old v6 has this on the compressor, the 3.4 has it on the banjo fitting, and taco trucks and runners have rack and pinion, so no taking a line out of those and slapping it in the truck, and the T-100 is about a foot and a half wider so the hardline is wider and wont fit.

Anybody know if I will be okay by not having this valve hooked up? I really dont want to have to buy a 200+ dollar custom hose for this. I would probably just shorten the T-100 metal line with a coupler in the middle somewhere before I spent 200 bucks I dont have on a new line.

[TroyToy]

that vavle is for the idle up so when your at a stand still and turn the
steering wheel the engine wont die, try to use the early model valve
there all metal ,the later ones are plastic i recommend you use it

[panty dropper]

Got the air filter system installed today, this K&N setup just came into the yard on a 97 tacoma that was rolled to shit, it seems to fit pretty well, the T-100 air box was huge, I dont think it would have even fit under the hood in the right spot.


I also got the ignitor installed in the same spot as the T-100 had it, and it bolted up to some holes that were already there

I adjusted the cruise control bracket a little, because at the stock spot, the old style cable was adjusted as tight as it could get and still had slack, if this works I will make it better, if not I will figure out something else.

[panty dropper]

Also picked up a floor shifter for the auto, this one is out of a 2003 tacoma pickup, looks like it will fit perfectly where the stick used to be, my console even attaches to the back of it in the right spot.


I picked up a few transfer case shifters also, and since the new toyota trucks have a manual shifter lever for the transfer case, I dont need one of those gay factory transfer case shifters, I mean, hell, the tranny shifter is gay enough, toyota never made a good looking floor shifter for the auto......ever, at least not in any truck/suv I have seen.

Turns out the stock 89 shifter for the transfer case fit awesome, I just turned it 180 degrees and put it in this tranny, and it comes up through the Taco shifter assembly right where it should, fits good even with body lift and most importantly, it does not interfere with the shifter at all and my leg wont hit it either.

if it came out of a T100, it is an A340F tranny.

Yes, you are correct, my bad.

Very cool project. Good information.

Where in OR are you?

Cottage Grove, right below Eugene. Thanks for the support in my insanity I got sick of reading about 3.4 swaps, I read over 50 posts on these builds and every one seemed to leave stuff out. Then I got the off road 3.4 swap magazine in my mail box, what a joke. In the first two days I was fawked beyond belief with wrong parts and wrong info and nothing was going as it was supposed to, and I cant be the first guy thats had trouble doing a swap. All these little things have added up to 2-3 hours a day at work scrounging up little pieces, trying this and that on four different rigs going "will this fit my 89 when I get home so I can go further tonight" And I do like the info on off road solutions, but I cant afford anything they sell, and I cant be the only broke wheeler on pirate. Besides, I like to know how to fix something I am driving, and what better way than to build it yourself?

I wasnt going to make a thread out of this, but after people go "everything bolted right up and worked perfect on the first night" Yeah right. Maybe they paid the 12,800 estimated cost to have a shop install the swap, and thats into a 5 speed truck. I could have been done by now if I left this truck a 5 speed but hey, thats no fun I just hope this makes the swap easier for a normal guy that doesnt have 600 toyotas at his fingertips and the ability to take whatever he needs every day to go and buy a 3.4 from a wrecking yard, and go, okay......I need engine, wiring, this little piece, and that one, and....etc and make one trip, go home, install the shit and be done.

Got the radiator installed last night. The lower hose inlet/thermostat housing off the 3.4 did not like my old chassis layout and radiator. I tried the 99 4 runner lower hose, 97 tacoma lower hose and the 95 t-100 lower hose, and they all hit the power steering lines very badly. I used the 3.0 thermostat housing and stock hose and that worked good. Here is a pic of the 3.4 housing.

I used the stock 3.0 fan with the 3.4 clutch. The fan and clutch off either should fit but the 3.4 clutch is about 1/2 inch thicker in the middle bearing area, should be heavier duty. I would have used a taco fan blade but I dont have a good one at the shop. I used the stock 3.0 fan shroud, and I used the stock upper hose off a 99 4-runner.
