99 Tacoma v8 swap

I have finally decided to pull the trigger and start this project. I have been reading, and thinking about this since I got my truck almost 9 years ago.

My truck currently:

1999 Tacoma ext cab, 3rz, 5sp, 4wd.

My plan is to run a 2002 non-VVTi 2uz-fe (4.7L v8) from a Tundra.






The engine came with an 2004 engine harness. (all 2uz-fe's are the same from 00-04) However there are some things i have found about the 2004 ECM that make things tough for this swap.

- In 2004 Toyota started storing VIN's in the ECM.
- In 2003 Toyota switched to an electrical throttle pedal and got rid of the throttle cable all together. All Tundra's are drive by wire, but from 2000 to 2003 Toyota used throttle cable.

The VIN in the ECM makes things tough because the VIN in the ECM will not match my Tacoma's VIN and show up on inspections. I might be able to have my Tacoma's VIN put in the new ECM, but I found a 2002 engine harness for a good price. In 2002, the 2uz still used a cable actuated throttle body which will match my Tacoma better. So I spent a little extra on a different harness and save money on ECM programing, and hassle with drive by wire. (I now have a 2004 Engine harness FS if anyone wants it)

A few random shots of the engine:

Broken camshaft alignment pin


This engine was said to have 194K on it... No lip at the top of the bore, and you can still see the cross hatching. This is cylinder 4.


This is the left cylinder head. #4 cyl is on the left.


Mark of the Beast!


The old cam gears on the fleebay camshafts


Once the cam gears where put on, I found that the alignment slots on the cam gears have been notched and now have some play. This play is probably what broke the alignment pins in the 1st place, that and loose cam gear bolts.

Any questions, tips, or knowledge is welcome. Please feel free to include yourself in the discussion.

Ok so a little update for you. 1st things 1st, the 3.4 and 4.7 do not use the same timing belt gears.

This is the front side of the gear


and the rear. You can see the notch from the alignment pin.


Good bolt/ Bad bolt


I spent last night pulling the valves out of both heads and this morning scrubbing the heads clean.

Note- CHANGE YOUR OIL PEOPLE!! GEEEEZZZ!!!!


Took about 20 mins to get each runner looking like this.



I still have some cleaning to do, but everything is cleaning up nice!



Both heads mid bath.

So A quick update to show I'm still here and working on this.

One of the heads had a "soft" spot in the combustion chamber. I noticed it when I was cleaning and then saw it start to grow. I tried a few other spots and could just scratch the aluminium with moderate pressure. Im not sure what causes this??









I called the salvage yard and told them what I found. Two days later I had a replacement head on my door step!

I picked up a top end kit from Toyota so I hope to have this thing back togther with a week or so.

Also, I picked up a 1uz bellhousing and will be running a manual trans.

Hi, I'm interested in doing this to my taco when my engine craps out. I've been following your thread. I converted my prerunner to 4x4, but left it as an auto. I know your set up is a manual, but do you know if a 2uz will mate to an A340F tranny? Thanks for being a pioneer!

Looks like heat damage to me, and judging that its on the quench (correct term?) area, I would say it was detonating. Thats my best guess, but when I blew up my old eclipse motor by running it too lean the top of my piston looked very similar to that.

Edit: I found it was very easy to scratch aluminum heads with minimal pressure in the past, especially when scraping gaskets. It also appear that happened on the exhaust side of the head too, which further makes me think detonation or running lean, would could very well make the aluminum very brittle and soft after it cools and solidifies again...

I asked the same question myself. I wanted to know if I could run the old auto transmission from my truck. In short, No you wont be able to use the v6 tranny behind the 2uz, but yes they are both A340's. The F means 4x4 and the E means 2wd.

Toyota uses the A340 behind ALOT of its engines. From what I can tell it was in Lexus models, Tundra, Tacoma, 4runner, and the Sequoia. I even think its pretty much the same as the transmission found behind the 4.0L in the Jeeps. With that said, The bellhousings are ALL different, TQ converters, and input shafts are different too. I would imagine that the VB and clutch pack counts are different too. Plus, depending on age, some A340s use a "detent cable" that runs up to the throttle body. My Tacoma had one when it was an auto. I dont think any Tundra's have this cable.

Btw, this has already been done, you just have to know where to look.


If anyone sees I am incorrect, please speak up!

Interesting... Either way it goes, I now have 2 good heads, and all the gaskets I need to start putting this thing back together.


I still have to strip down the head I just got and put new valve seals in. the right head I have all cleaned up and new valves seal tapped into place. My home made tool I used to take the keepers out doesnt really work that great fro putting them back in... Might be a slow process getting it back together... Its only 32 springs, and 64 keepers.....

Thanks for your reply and info! I'm sorry; I've heard people dropping V8 tundras in tacos. I meant starting up a thread to install a V8 tundra engine into a taco. I just haven't found a complete online write up about swapping a tundra V8 into a taco until I ran across your thread.

Yeah, I know the 1U from Lexus have been dropped into a taco before. Smithers dropped one into his 95/96 taco. But after reading his write up, the 1U height wise is a little taller than the 3.4 V6 taco engines we have, but he had a body lift on his truck so it wasn't a problem and had to hack of some of the sheet metal to get the headers to fit. i don't want to install a body lift on my taco to get the 1U in and do the other stuff. Also, i read how 06tacov8 dropped in a 3U in his 06 taco. Furthermore, I've been on www.lextreme.com. Did research on the swap.

So I believe the current tranny you're using in your taco is the W59 transmission right when you converted your taco from auto to stick? But, you stated that you're using an 1U bellhousing to mate with your 2U. How is that going to work? Just interested in your line of reasoning.

Yeah, my taco is a 03 double cab prerunner. Kept it auto because I didnt want to add the extra stuff required to have a manual. But I do miss driving a stick. My previous taco was a stick. I went the auto route with manual locking hubs because I didn't want to deal with the electronics and ECU. After seeing what you do with your V8 swap, I want to do the same thing with my taco, but I was wondering if this could be done with an auto so I don't have to make my truck a manual and then do the conversion. Just wanted to keep it simple. Haha. Sorry for all the questions. Thanks for starting up this write up! Good luck on the install! Looking forward to your future posts!

I have read both of those threads,Lextreme. V-eight, TundraSolutions, Pirate, and any other thread google has brought up. There was a thread on this forum where a Lexus 2uz was put into a 98 Tacoma. However that thread is pretty much trash now because the OP deleted all of his posts. I had thought about running headers, but have seen and been told they wont clear the strut tower. I plan on running the stock manifolds, they will clear.

So I believe the current tranny you're using in your taco is the W59 transmission right when you converted your taco from auto to stick? But, you stated that you're using an 1U bellhousing to mate with your 2U. How is that going to work? Just interested in your line of reasoning.


Correct, I will be using the W59. The 1uz, 2uz, and 3uz all have the same bellhousing pattern, and this bell housing was from an A340 series transmission. Really there is no difference in bell housings, this one was just the cheapest I saw, so i picked it up. I plan on using this kit from 1uzfeswapkit to bolt the bellhousing to the transmission.

Yeah, my taco is a 03 double cab prerunner. Kept it auto because I didnt want to add the extra stuff required to have a manual. But I do miss driving a stick. My previous taco was a stick. I went the auto route with manual locking hubs because I didn't want to deal with the electronics and ECU.

Keeping it Auto would be alot easier because the 2uz never came to North America with a manual. In AUS, there was one, but getting those parts here is $$$. All you would need to do is switch the engine harness and change to a V8 A340. I am pretty sure they T-case you have will work.

I am working with a guy that has done 2 of these swaps, and a few other motor swaps.

Dont be sorry to ask a question, you may think of something I have not thought of, so ask away!


And for the record... Buy a whole parts truck... or atleast a running engine!!!

For those of you wondering, this is why headers dont work...

Smithers Did some really great work, and the credit is all his! Here is his build thread! These Pictures are from Page 3, then on page 5 he cuts the ends off the headers.

Thanks for the advice! Yeah, I plan on slowly acquiring the tundra parts since my engine is still going strong! Not in a hurry. Guess, I'll be lurking in the tundrasolutions classifieds and other places. haha. Look forward to the day when my taco will have a V8 in it! Looking forward to your updates! Please keep them coming!

Time to switch gears for just a second. I want to take a quick second to document the 1st of my harness mods. Well, this is not really a "mod" its more of a repair, but not the less I brought pics for you illiterates.


As I started above, I picked up a 2002 harness from "apimpdad". It was complete minus 2 plugs, which was better than the 2004 harness since it was missing about 5 plugs. The 2 plugs missing on the 02 harness where the alternator, and evap plugs, which where on the 04 harness.


Evap wire when I started.



Missing Evap plug


Wiring harness opened up and the wires stagger cut so the "bump" wont be as big.


The plug soldered on and taped up. Notice there is no bump in the repaired area.


Harness tapped back up and ready. I wish the tape matched the loom.


Cut alternator wires.


Missing alternator plug


Plug soldered to harness and tapped up ready to roll.



That's all for now, sorry I don't have more for you, but soon. The motor is pretty much back together and ready. I just need a timing set and to check valve lash. I also picked up a complete stock intake.

So I did more research and I decided that I will use my A340F. I plan on slowly purchasing a 1U/2U/Tundra Bellhousing (whatever's cheaper ), TC, oil pump, and input shaft and interchanging the parts! Hybrid Tundra/Taco A340F! It's heck of lot cheaper doing this than buying a V8 Tundra tranny! haha. So stoked right now!

Also, question. I know you haven't put your 2U in your taco, but what mods do you have to do to the engine/frame mounts needed to get it to stay in bay? What are you plan on doing if you don't mind me asking? Cant wait to see the process of you putting your 2U in your taco!

Bellhousing info pulled from Lextreme.com under the adapter section.

Quote:
Note that there are two different V8 bellhousings – U1 and U2. U2 are fitted to crown (centre sump) engines and U1 to Lexus and Soarer (front and rear sumps). The difference is that the bellhousings off Crown engines have the gearbox indexed relative to the motor by about 7 degrees; the others are in line.

Consequently we have had to make 4 different adapters: U1 for W/G, U1 for R, U2 for W/G and U2 for R. We sell these for $250 each.
From what I have been told I will need to clearnace the fire wall just a bit for the stock manifolds to fit. Also, I have been told the radiator from the v6 wont work because the inlet and outlets are on the wrong side and its not big enough to keep the engine cool wile towing. I have not made it far enough yet in my travels to find out if the 4cyl radiator has the inlet and outlet in the right place. I also wonder if the v8 radiator will fit? I the thread that was posted on here where a 2uz was put in a 98 Tacoma, they used a Chevy sbc aluminum radiator and v8 4runner stock hoses.

I am 99.9% sure that I will end up making engine mounts, both the ones that bolt to the block, and the ones that are welded to the frame. I plan to reuse the factory rubber isolator from my Tacoma to go between the two mounts much like Smithers did in his thread linked above. I plan to sit the engine in as low as I can.

The engine's oil pan will fit nicely around the crossmember and front IFS axle. That will pretty much dictate where the engine will sit in the engine bay. I dont think I will need a body lift to clear the hood, if so, I will work with it.

I plan to run the Tundra power steering set up, but have not researched yet if the lines from the pump to rack are the same or not, or if the Tundra lines will work for me or not.

I know that I will have to have AC lines made, but im not sure yet on the specs.

I plan on using a 280z radiator. Ah I see. Thanks. I'll check out the Chevy sbc aluminum radiator.

After additional research, all the writes up I read for 2UZ conversions everyone used a body lift because top of the engine sat very close to the hood and the stock manifolds sat very close to the fire wall. I think I might have to install a BL to my taco...but, after viewing your install, I hope don't have to. We'll see.

Yeah, I live in Cali so I have to purchase a 2UZ from a 2003+ model to meet CA smog regulations. I have three questions. Are the 2003 tacos also throttle cabled too? Also, I reread what you purchased so far for your conversion at the beginning of your thread. I thought you need to buy a V8 ECM along with your 2UZ for the engine to run. Are you going to run your 2U with your taco ECM? Are you going to switch out your cluster or run the taco one? I'm still trying to decide.

NC has the same rule, the engine has to be the same year or newer. Lucky for me the 2uz started coming out in 2000 for the Tundra's. I would say go for an 03, it would be easier than a newer 2uz just because of the electronics, however if you get a VVT-i engine you gain 40hp right off the top. To go one step farther, if you are going to go threw all that, I would try and find a 3uz (4.3L). They run 330ish hp stock. Its really up to you and how much work you really want to put into it.

I am pretty sure that somewhere in 02-03, Tacoma's got drive by wire, but I am not sure. I dont have one, and I have never worked on one. Sorry.

I do need a 2uz ECU, I have been looking at them on Car-Part dot com and they are pretty cheap from $50-100. I just have not bought one yet. That list is an "as of" list, meaning that what I have for the swap "as of" the time of the edit.

Since My Tacoma has a 4 cyl, the tach WILL WORK. The v6 tach wont work, it will be off by 30% or so. I plan to keep my Tacoma as "stock looking" as I can, so I will be keeping my cluster. Plus it has the correct miles on it, and mine is kinda custom.

I find myself in need of these plugs. They are connected by about 4-6" of wire. This little peace of harness connects the TPS to the harness. I have no idea why Toyota did this, but I need it.....






I also need a PWR steering pump and res, alternator, AC compressor and all the brackets and bolts. If you have or know of someone that has all or some of these let me know!

I'll just stay with a 03 2uz. I actually got a deal where I'll get a COMPLETE engine (engine, alt, steering pump, ac comp, bolts, brackets, etc...), wiring harness, and ECM from a 03 Tundra for a good deal. I just want an easy install.

3uzs were use in 2003 in a LS 430, but that used the A650E(5speed auto); GS 430 with A341E, A650E, and AA80E; and the SC used 5speed auto (02-05). I just want to use my A340F I currently have in my truck. Don't want to alter my drive train with another tranny. Want to keep this install simple. haha.

Ok. I did more research and pulled my fsm out and looked at it. My truck is drive by wire. In 2005, when Toyota did the redesign to the taco, the mechanical cable was eliminated and everything was electronic to throttle.

Ah I see. I'll do more reasearch to see what I can do with my cluster to keep my correct miles that is registered with my truck. Thanks.

Buying a whole engine like you did is the best way to go. I thought I might be able to save some $$ and fix the one I bought, but as you can see Im in for more than it really worth.

That all sounds about right. I am pretty sure the A341 is pretty close to the A340.

With you cluster you should be able to just swap a tach from a 4 cyl cluster and keep your ODO.

Yeah, just like you said it's less of a hassle if you get a whole engine with the accessories. glad it came from a donor truck.

Yes, but not exact. Electronics are different. Also, the output/flange of my taco transfer case (tc) won't mate to the A341. I would have to put an AW4 (Jeep tc) to mate it with the A341. That would be a pain to do. I rather work with the parts that are already available to me. It be cheaper to buy a 1U bell housing bolt it to my A340, swap out the input, oil pump, and torque converter, and call it a day. I will be saving more money if I did this.

Yup, that's how I am going to customize my V6 cluster. But the problem is, I would have to buy a pre-2001 4 cyl cluster, take out the inserts, and put it in my 2003 V6 cluster because the tachs on pre-2001 went up to 7k rpm. The 2001-2004 4 cyl tachs are the same as my V6 cluster going up to 8k rpm. Furthermore, my cluster goes from white inserts to black ones because pre-2001 Toyota didn't make white clusters, unless it is an aftermarket. But that doesn't bother me, just as long as I keep my original odometer.
