FWIW, that's a really poor location for an Intercooler. The opening for the hoodscoop is undersized for that Intercooler, there is no attempt at ducting what little airflow there would be through the Intercooler, and finally the radiant heat from the engine is going to really diminish any benefit from that Intercooler further.
Slow build, fast truck.

Dropping a 5.7 is a good idea.. Which trucks do they come out of? Going junk yard diving next week for spare parts.
If I get a 5.7 how many lbs of boost do you guys think I can put on it?
If possible I wanna do the turbo/supercharger and turbo in the rear end too.
No way in hell I'm making my truck look like that. 22" chrome is tacky... 18" matte black with red or white accents....
Oh and I might be chopping the rear end down a bit.

HP record on stock 5vz? What are the weak links I will run into? - Page 8 - CustomTacos.com Forum
Check this out. It may lead you in the right direction for what you wanna do. There is allot of *****ing And it is from last year but it's still a tt 4runner. And also please re consider adding a turbo to the rear. The only reason it's ever done is because of laziness or lack of confidence to take on putting a turbo under the hood. It's in my eyes the stupidest way to do a turbo setup. If your gonna do it do it right.

The 5.7L iForce is from the current gen tundra/sequoia. Unless you mean a 5.7L Chevy (350ci), which is blasphemous in a 'yota but has serious potential for power and torque. A supercharger will give you better response and low end torque, but is also causes some parasitic power loss due to the fact it is driven by the belt. Turbos are much more efficient, the drawback mainly being the boost lag. If you really want to invest time and money a sequential twin turbo setup would take care of the lag, while a larger single turbo setup, or non sequential twin, will be the best route for big hp. The intercooler on top of the engine (like a Subaru) will keep it protected in case of collision, but for the best efficiency it needs to be a front mount, which you could relocate the radiator to the rear w/fans and put the intercooler in its original place. The rear mounted turbo (muffler location like the STS kits) will have more lag since it has to compress a much longer stream of air not to mention it is pretty vulnerable in that spot. Twin superchargers would be a tuning nightmare I think. Or, just get a 2JZ, plasma cutter, and a welder.....

The TRD Tundras with the 5.7 supercharged from the dealership get over 500hp without trying I read yesterday.
And what the guy further up posted to, I have read about our V6s that were super pimped out getting around 800hp.
In my opinion, a 3rd gen that can do everything and then go wicked fast would be insanely cool and awesome. And I think a supercharger with high boost and modified to handle it would be a huge upgrade over the bare V6, but if you really want to give people a run for their money then you should either swap or make/modify the current engine so it's very high performance. I want to put a ton of hp into a 3rd gen as a project when I get out of school. Whatever you do, good luck and I think you'll have fun and a sweet truck with any route you go!
EDIT: You could also think of doing nitrous oxide, maybe in conjunction with a supercharger/turbocharger. You could boost with the nitrous oxide until a turbo kicked in, and then maybe even have the option to use the nitrous once the turbo was spooled. Though again, you would want to pimp out the V6 to and drivetrain to handle all that power.

I would stick with a yota motor. I don't trust American junk.
I would definitely relocate my radiator (it's pretty badass having it in the rear. I would vent my rear fenders and pipe them to get airflow to the radiator.
I wouldn't mid the lag, these trucks already have a pretty decent amount of you're. The sequentials would be a pain.
I don't want nitrous, and I am pretty sure it's illegal in Illinois. I still want my truck street legal
If I did the exhaust turbo, it would be in addition to the front turbo(s)
So if I want to do the 5.7L iforce, I should try and find a wrecked current generation tundra? Or does it have to be a TRD tundra?
If I use the 5.7L iforce motor, I will need the transmission from it also?

The exhaust turbo is just a cheaper, easier way to turbo a vehicle. It doesn't have any performance advantage at all. It requires more piping, so more weight, and it'll be exposed to the elements unless you build something to protect it which, again, more weight. As far as I know the Tundra 5.7L is the same regardless of TRD package or not, and I would think you would need the trans/t-case from the Tundra, I'm not sure though. There are a few folks around here who have more experience and knowledge about this than I do. I think a member, Singtoe I believe, has a 4.7L iForce build thread that came from a Sequoia, you should check that out

Yes, and the ECU's to control both the engine and trans. Or you could fabricate an adapter to mate the 5.7 Toyota motor, with a suitable trans. Although that would be a lot more work.
Physically fitting the 5.7 engine and trans, in the 3rd gen, will take some Fabricating of the engine bay and the transmission tunnel.
Then you'll need to find a stronger rear axle, as the stock 4Runner axle likely wouldn't live for any length of time behind a stock 5.7. To say nothing of it's lifespan behind a hopped-up 5.7. The Tundra rear axle could be narrowed to fit the 4runner body. Then either lift the 4Runner to clear the Tundra rear axle, or modify the 4Runner frame and body for clearance.
If you use the Tundra rear axle, you will need to change the wheel bolt pattern of either the Tundra axle, or the existing 4Runner front end, if you want to run the same wheels front and rear.
Then there's the wiring to make the Tundra drivetrain work with the gauges in the 4Runner.
Depending on the what the emissions laws are where you live, there is the possibility of what you end up with not being emissions legal. If that proves to be the case, it couldn't be licensed for the street.
So research that before you get started, if you want to drive the final result legally on the roads.
It should be a great project for someone with highly advanced Fabrication, Mechanical, and Electrical skills.
Good luck.

I say just go and buy a 2012 Tundra. Haha, all this talk of, use the Tundra engine, use the Tundra transmission, use the Tundra axles. I think the best bet is to go get a new Tundra and do a body swap
I'm just playing devils advocate. Carry on.

If I win the lottery. That will be the first thing I do!!! Lol
If only I could win it xD
I will have so many toyota sitting around if I won the lotto.... Lol ;p

I am all out for doing a 3UR-fe swap but this is all talk. Unless you had a tundra, sequoia, landcruiser or Lexus lx570 and you wrecked it, and bought it back from the insurance company, you won't be doing a swap.
Complete late model wrecks go for as much as dealership 4runners. You will need a wreck to do the swap too. motor, driveline, ecu's, wire harnesses, evap, key immobilizer, exhaust, air conditioning, power steering, and fuel pump.
As for the trd super charger, that is another 5 grand and it will not work with the flex fuel motors.
Pipe dreams are good have.

He is reaching for the stars [MENTION=59542]Singtoe[/MENTION], he'll level out.
I think 4Runners are nice, I love mine. But sometimes investments need a strong dose of practicality. I can't tell you, OP, how to spend your money, nor should I. But I can say that if your sole purpose is for speed, I suggest another platform. You would find your time so much more worth it building an RX-7, a Nissan 240, or a Lexus. I hate shooting down dreams, but just be careful with how far you go. I've seen people get halfway through a build and finances prohibit the build from going any further, forcing that person to part out their vehicle, its heartbreaking to see. I just don't want that to happen to ya.
My suggestion:
Take engine apart and maintenance it, clean it of all sludge. Clean heads thoroughly. Inspect block and ensure the structural integrity beforehand. And then:
ALL ON THE 5VZ-FE
TRD Supercharger (If you can find it)
Doug Thorley headers (Or the extremely evasive TRD headers, good luck)
URD 2.2 Pulley
URD Idler Pulley
URD Crank Pulley
6 "Proper" injectors, or the 7th injector mod. (Pref. 330cc)
Water/Meth Injection system
Then lighten your load. Take out the unnecessary things. This seems like the most practical build. You can always throw a turbo onto the exhaust, but I suggest an engine bay build.

That's the easiest, most reliable path to take. I would love to have those exact mods on my 4-Runner.
But I have realistic expectations and OP should, too. It'll still be a 15 second truck, at sea level, with 1/16th tank of gas and the interior removed (including that high priority sound system).

Haha, the owner of that Vette in his forum. Could you imagine the conversations and build list he gave? They were all like, "WTF?! 40" tires bro? You sure?"

The OP has a vision of what he wants.
My list of issues that would need to be addressed, only scratches the surface. It would be far more complicated than my post may have made it seem.
The OP seems pretty gung-ho to do this. So I was just offering some advice as to what would be required, at a minimum.
Carry on.

The v8 conversion would be nice if I can find a donor tundra. Went through a junk yard today, 4 4runners and a taco... Nothing else decent.
I'm gonna stick with my v6 and go with it for now. If I get v8 hungry ill start with a dead 4runner.
I do have big plans. But logically won't work.Similar threads
