Turbo 2uz-fe?

Is the engine capable of a turbo application with say just some stronger rods and turbo pistons. The block is iron so it should be able to handle it. Just kinda curious as I'm wanting to get some decent horsepower gains out of my Tundra.

yes, but no more than 5 pounds of boost.
or search the forum. .
or look at boosted tundra's. or STS turbo's.
boosted turbo's are now a direct bolt on.& ifou get your truck to them, they will install for free.
also 2003 's have a trd super charger, look here and on ebay there are alwasy a trd s/c for sale.
also you can get in touch with lextreme, for all needed parts.
good luck,
gorilla

Why is 5psi the max? Even after replacing the rods?

I am running 9psi boost (supercharged) with stock motor, but that is maximum for this engine. If you replace Rods and Pistons, with better ones, I think you can get even more boost. It all depends what you are planning to do.

If I had the coin I would be really considering this:
YouTube - Turbo Toyota Tundra: THE TUNDRACHARGER
It looks like a very nice setup.
Then, if you upgrade the internals down the road, this kit could also be upgraded. Id love to see someone build a 600-700 hp 2uz-fe for the street.:devil:

Here's something to give you an idea.
This is the company that originally worked in conjuction with TRD to develop the T4.7L TRD supercharger when TRD was a division of Toyota.

Magna Charger manufacturers intercooled supercharging systems for late model GM and Ford cars, trucks and SUVs utilizing OEM quality Eaton hybrid superchargers. : Here's the charts on the M90 design's efficiency charts. Intake temps , etc. which are high at 10 psi.

Anyone know about how much the Tundracharger costs? The universal STS setup is about $3,000...
I've seen it listed somewhere as $4999.... Maybe on one of their youtube vids.... And honestly it looks like they use a no name brand turbo, I would stay away. You are better off piecing a kit together by yourself.

But with H-Beam rods and low compression pistons with some stronger headbolts you could easily get more than 5 psi and way more than 100rwhp. Anyone know about how much the Tundracharger costs? The universal STS setup is about $3,000...
gonna need to drop the compression too here. 10:1 is a little high for a turbo setup. It would still leave you with 12psi max...or there abouts. Drop the compression down to 8:1 or 9:1 and you could get more.

also remember guys... once you take an N/A motor and add Forced Induction, you'll want to upgrade the fuel system... especially for 12 psi. Reflash the ECU or get some sort of EMS, Wideband o2, A/R Meter, FPR, bigger injectors, etc...

there will be a point to where you just cant get safe power from the stock components.

So who has pushed the limits of the stock internals? It would be a fun experiment to see what the 2UZ would take. The supporting mods would be the biggest factor, namely proper tuning and knock control. I bet it would be a hoot to make a drag truck out of a standard cab long bed strippy 2wd truck. I am still too new here to know if anybody has gone far on a stock motor, but the factory design looks like a good building block for a nasty turbo motor.

indeed Mr.Burns...

I see you are an EVO owner... I'm an ex-DSM owner myself. I had a 90 GSX with Slowboy 2.3 Stroker and the AMS GT37R Turbo kit.. ran AEM EMS and stuff. I sure do miss car but my EX-wife said it was taken up all my time.... lol.. go figure... she's my ex now...

Tuning is gonna be the key factor in how much power you can make.

Read and enjoy.

From I being told that our motors can't go over 400 flywheel hp (and about 450 lbs of torque) on stock internals. Anything more then that, you have to build motor to your application.

No... no... no... the rods/pistons are good for up to 500 HP runnin on the ragged edge. Any thing over that and upwards to 550 hp and the rods snap, pistons explode, and all pieces grenade through the side of the block.

You're already sitting over 400 hp on yours Tinik at the crank. You still got a ways to go. What blew up the
previous motors was the crappy TRD piggyback tune. That or doing what the member in the link above did running 9psi, long tube headers, full flowing exhaust, cold air intake, methanol injection , Uni-Chip , 25-30 runs of 75-100 shot of NOS, all properly tuned. And running upwards of the 500 hp mark and it letting go like Wayne's motor did.

I see problem with - going over 400hp = 2 extra injectors. Even there is enough fuel, and proper mixture.... Here is why I see problem: When 2 injectors spraying fuel, I have no clue where all of that extra fuel goes (and which cylinder is getting lean and others rich - who knows). I think at that horsepower you need bigger fuel injectors, bigger fuel pump, pay very good attention to a detail, make sure your truck is tuned properly. Other-wise over time, even more then 100 runs, you will jeopardize internals of your engine.

thats kinda what I was saying Tinik...

creating safe power is all about flow and tuning... you have got to have the right amount of flow coming in and matching flow going out. and your ECU needs to know that. This guy prolly predetonated and blew the **** out of his motor. let be serious.... 1000+hp from just moderately upgraded internals? yeah right... people spend 20-30-40K on a motor that just gets to 800-1000hp... this isnt a 3.6L Titan Stroker here guys... it's a low compression v8... not to mention... where thehell is all that pwer gonna go? need a new rear end with different gears... upgraded transmission gears and such... c'mon... I dont believe that sorry one bit. 600hp on that truck is a friggin killer street machine.

I'll be going with prlly the STS kit on my truck.
