Ok guys this one is a ways out but something to consider. I had initially considered the TRD sc for my 3.4L then I thought a new 3.4L motor mated to a sc would for sure be the way to go, then as I researched more I found there are quite a few toys needed to make it work properly. I had also considered a lex or Toy 4.0 1UZ-FE swap, the runner ways a bit less altering the power to weight ratio. I'm nor aware if a successful 4.7 swap has been done but know the 4.0L is popular. My goal in the long run 1 year or so is to swap my engine between 200K- and 220K, with either of the above. I know a 4.0L mill will be cheaper than a 3.4L, and thats just for the motors, yes low mileage is the only option. So what do you guys and gals think? I want a reliable close to stock as possible (with a bit more power) for the simple reason of reliability and longevity. Whacha got?

I don't know too much about the swaps, but the 4.5L is a I-6, not a V8.

4.7 would be cool, but have you looked into a 4.0 V6? I'm not sure if that's an option or not, but I'm sure it's very possible and since the engine's lighter than the V8 (I'm guessing), it would be better for the weight distribution as well. Plus, you still get 17/21mpg. Just a thought.

yeh i thot the landcruiser 4.5L was a Straight 6. I would think that would be better as choice of the 4.7L V8.

As far as I know the computer has not been able to be mapped or something where as the 4.0 has and can be made compatible. Though I agree the 4.7 would be a wonderful addition, talk about power to weight ratio shyyyt.

the i-6 would destroy your front end, those things are HEAVY.
i would rebuild the 3.4 with a blower and a few go-fast goodies... still being reliable.
A swap is going to cost way more than rebuilding a motor and throwing a blower/fuel kit on it... now if u had a 3.0, i'd say swap, but i'll be throwing a 3.4 in my truck n building it, you already have one...

Ok but say I wasnt interested in a rebuild. And it was either a straight swap 3.4 sc'd or the 4.0, looking to recoup some cost with the sale of my original 3.4.

I'm thinking about a swap with these same two options also. I think that the 1uzfe engine only weighs a few more pounds than the 3vze. If my engine goes soon I will probably go with a 5vze but I really want the v8.

Edit: just realized this is in the 3rd gen section.. whoops

Funny timing of this post. My buddy just bought a smashed 2000 Lexus and is going to try and put the 4.7 into his tacoma...I don't think it is going to work out all that great, but I will keep everyone posted.

Strictly for reliability, a newer 4.0L V6 will be very reliable. However, you will need to have new engine mounts welded on (I'm guessing), and a new transmission mated to it, which might also need to be modified.

Just shooting from the hip, I'm guessing the swap (4.0 or 4.7) will cost you about $7-10k. Contact these guys. Not sure how helpful they will be, but seems like they know what they're doing.

I cant remember what I found about the 4.7 that wouldnt work but there was something. Otherwise I would have to consider swap able performance mods for the 3.4 headers, exhaust . etc. though none of these would add quite as much of an increase as im interested in. Don't get me wrong I want some more power not white smoking drive shaft snapping power. Not what I'm into that (would have bought a supra and tweaked that) I drive a ˟˟˟˟ load and even further for my wife and I's adventures so reliability is the key. If there was a way to do a basic install of the sc with minimal extras I might consider that as well. I have seen very elaborate sc setups which look far from extremely reliable.
As far as cost I was under the impression the 1uz-fe could be very affordable 1-2k and the parts 1-2k add in misc. 1k and high side of 5k. Or new 3.4 mil 4k sc 2k sc parts 1k sooo 7k ouch

I think you will be best off to just keep the 3.4 and rebuild, if necessary. If you go FI, your reliability will go south. If you plan on a swap, it'll be a lot of cash no matter which engine you plan to go with, since you will need a custom fab job.

How about re-gearing? Best bang for buck in performance in most cases.

If you have the time and patience I would definately recommend doing the 1uzfe swap. Those blocks can be purchased for a couple hundred for a LONG BLOCK, and boy can they handle boost

Have yet to price out a re-build but thats not going to make the numbers I'm looking for. 60 more HP would be nice and the 1uz-fe would do the numbers easy , and with minor $. As far I have found the motor will cost $600-$1500 depending on condition and miles so I figure $1500 plus bell housing adapter $700 and the the fitting and misc. $1000.... I'm pretty mechanically inclined and can do most of this myself, the ecu wiring will be, well I dont know.

If only you lived closer, Id help you out. Im sure you could find lots of fellow yotatechians to help you out

Man I appreciate that, I really do. Its not every day people offer up. I only have a few close friends and when I tell them what I have in mind I think its just way over their head. They just look at me like whoa sounds cool. But that is no help and end up making it myself or trying to find a descent welder that can do it just like I want. I know the post keeps saying 4.5 but I changed it to 4.0 was tired last night when I posted this. I think a re-build is a good price feasible option, yet it still limits the added power I'm looking for. Like I said not looking for white smoking, drive shaft snapping power. Now I'm aware the 1UZ-FE can be turbo'd but thats a whole other story I wont venture into (would be freaking awesome though), I have to exercise responsibility and caution. As stated earlier I want a reliable predictable engine with more ponies. I think the 1UZ-FE is perfect with +/-240hp and +/- 285LBft this would be just what Im looking for. The difference in weight is minimal and should only be a few pounds. Therefore resulting in a power to weight ratio that will be very nice.

I'm wondering what the price difference would be for a new 4.0 V6? At ~240HP and 270 FT/LB, it's not bad at all. I'll have to check around to see what the going rate is for these engines. But I'm sure the 1UZ would be more cost effective.

blink

Aaron, well having had a 5vzfe s/ced with all the goodies and then some, I would definately recommend the stock 1uz over a modified 5vz.

p nut, the 1grfe is way to expensive. your talking 3k+ for the long block alone, and I cant even fathom trying to tweak the electronics to work correctly.

This is a lil late, but I know someone did the new 4.0 V-6 swap. I thought it was on here, but I can't remember. The guy bought the entire wrecked Tacoma or 4runner. I think you have to use the engine, transmission (which it would be fun to have the 6-speed), and the transfer case; and then have the drive shafts built. I'm sure it would be cool, and different; but way too expensive for the price of swapping the 1UZFE in and having the same basic power numbers. There is a guy on pirate4x4 that is working on a 1uzfe swap kit. I know he has some bellhousings made for a few different trucks; I just want the entire kit at one time. Hopefully he can finish it before I lose interest or get another vehicle. He has also mentioned making a lil supercharger kit for the 1UZFE also. Would also be cool, but no telling on what kind of time frame. You can check 1UZFE.com and lextreme.com for adding more power to the 1UZ also. Sorry so long, too much to say. Hope it helps some.

4.0 v6 is possible but not so practical to a lot of ppl. the reason being the drive-by-wire throttle. a lot of ppl are fond of doin the mechanical parts but not the electrical part.

the guy on this board did a swap but a lot of body harnesses were transferred straight-over. also, custom mounts, of course, had to be made.
