I know it's been done with a Tacoma and the engine bay is pretty much identical to a 4Runner.

Also, search... This comes up from time to time and you'll get the same answer every time.

Could you elaborate/quantify your opinion? I'm just wondering why it is so wrong... The HP is nearly double to the 3.4L V6.. It's a toyota engine. It shouldn't cost much more than adding a supercharger, and not gaining more than 20 to 30 HP, on a great cool temp day..
You wish. :yo:

alright negative Nellies, why just dog the idea without adding some back up? A person has to ask the questions, before they jump in.
Why is it so wrong?
How do you know it's so expensive? Did you try it, spend a crapload, and then just want to dog someone else because you learned the hard way?
bring up some factual information instead of opinions..

Engine swaps have been discussed a million times and the same issues factor in to all of them; Custom mounting, transmission interchangeability, custom cooling (if needed), custom wiring, etc...
Suffice it to say, if you're asking these questions and assuming that the cost of an engine swap will be a wash compared to a TRD SC then you just haven't bothered to research it. Do some research my man, put forth some effort rather than expecting to be spoon fed the information.

If you won't be doing the welding and fab work then you won't want the bill.

You see, That didn't hurt a bit did it? No I haven't. It was an idea that flashed through my mind, and I figured it would be a good discussion. Which is what is happening here in your last post (all but the last part)..
Appreciate your time.

Absolutely. The fab work would be very costly, if it were hired out.

Thank you, I read most of a couple of those, and the fab is extensive. It seems other than that it would be about as difficult as any other swap.. But is doable..the could to should Ratio is where I was looking to get some discussion. Thank you great post.

Well, an s85 would be way more expensive and absurd.
I agree. Asking such basic questions about such complicated things means that not enough time has been spent researching. And if you can't be bothered to research, than you won't be able to do the swap.

The major issue that come to mind is the extensive length of the I6 vs the V6. Length-wise, a mid-sized V6 like ours is about the same length as, if not still shorter than, most large 4-bangers like the 2.7.
Having not read any of those threads, and honestly not caring to, I would imagine most of the fab work comes from dealing with that obstacle.

Well, we can start off with the actual engine mounts, how will you have them made unless you know how to weld? (keep in mind at this point your truck is sitting with no engine, and the 2jz dangling by an engine hoist. Will you contract a fabricator to come over to your house? measure everything, then run back and forth between your place and his machine shop?), then what will you use to adapt the 2jz to your transmission? What will you use for a torque converter because the splines are very unlikely to match up. Custom torque converters, not that cheap.
BTW, good luck finding a good used 2jzgte for anywhere near a reasonably price. Enough time has passed that you can't just find a bunch of JDM ones in a warehouse, and everyone from Supra guys, Lexus guys, hell, even Mustangs, 350z's, 240's are putting those into their cars.
Next, it's very unlikely the factory turbo system to exhaust will just line up to the 4runner chassis, cross members, etcso I'll give you a break and just assume an eBay manifold puts the turbocharger in a reasonable enough place and you won't have to have one made, you still need a fabricator to work out all the wastegate recirculation to exhaust plumbing.
Next we have wiring, engine management, tuning. Do you know how to do these things? --And have the speedometer, gauges, warning lights, shifter all work. Do you know how to do all that? Without it being months of work?
Then comes all the trivial stuff, finding the right intercooler to fit behind the stock bumper, fabricating mounts, fabricating intercooler plumbing, the stock ecu will work, but might throw 10 different engine codes including emissions codes, so you'll either have to hunt every single one down or go with an aftermarket engine management system and tune.
Next we can move onto reliability, those one-off wastegate recirculation pipes might not like the bit of flex from those one-off engine mounts or the flex of the factory 4Runner transmission mount, the vast, vast majority of stand alone engine management setups need constant attention. That 20-25 year old engine harness that you found used from that guy on craigslist has now been hacked, cut, extended, etc, runs across hot spots in the engine bay, etc. This also assumes there is absolutely nothing wrong with that used engine, electronics, etc. Good luck getting your money back for them after you've had them for months trying to get it to work in a one-off setup.
Finally, some day, that sweet 2jzgte is going to make some good power, mild setups will make 450-600 crank horsepower. The 4Runner stock transmission probably won't hold that and will blow up. What now? Keep blowing up stock transmissions? Find someone to build a one-off built one? Figure out a way to adapt the Supra transmission to your transfer case? Repeat step one.
So we have...
Good used engine
Custom engine mounts
Engine harness
Intercooler
Custom plumbing
Turbocharger
Wastegate
Blowoff valve
Custom plumbing for all the above
Custom torque converter
Custom engine to transmission adapter
Stand Alone Engine management
Tuning
Electrical's unless you're really good with these.
Then any frankenstein car, you better be good at troubleshooting and working on stuff on your own. Most shops won't want to touch it.

I've helped shoe horn the 2j in a couple cars and all went with single turbo set ups for space and Fab work.
Engine mounts aren't bad your going Toyota to Toyota after all
No it's not expensive there are cheap ways to build a motor. Go into a Supra forum and those guys are super helpful and knowledgeable.
And wiring. Stand alone Ecu will not only make everything easier but will give you less headaches tuning later in down the road.
2j single turbo bpu in a 4Runner? I mean wow.
If you've never seen a simple bpu Supra YouTube it.
I say DO IT.
Just plan everything out. make a list check it twice, before you start the project. We did this on my boys 2j 88 starion, and had the car done and running in a weekend. Same thing on another friends 240sx.

All great points
BUT not as bad as you think and not as much work. Everything is very doable, you just have to have patience and know how. Witch I hope the op has especially when even thinking of doing something like this.
It's not like you can just read a write up and look at pictures to get it done like most guys do on here.

Exactly. But....I've noticed most Toyota owners are brand loyal bordering on sheer lunacy. Eventually, their pocketbook makes them wise up....but it often takes quite a while.
