I got all excited when I read the title of the thread
Ya, sorry about that. I was wondering if that would happen. I looked at the SC and I don't know how it would fit. My father's ('05) tundra has THE 4.7L and the engine bay is noticibly larger. I don't know how I would shoehorn it into the 4Runner. Does anyone know if anyone has done it? Another thing the SE needs is a ram induction kit for the hood scoop!
Exactly. They would need to redo all the intake tubing routing. Basically, you couldn't buy the kit from their website, install it and go. You would need to custom fab some piping, which isn't hard, but is not exactly plug and play...sblbdr said:
It would void the SHIT out of your powertrain warranty, no question. Ask URD about it and see if they'll stand behind their kit and pay if something does happen in the long term, though I doubt they would. I've probably crossed the line on my warranty and all I did was adjust the air/fuel ratio.

Ya, I can foresee some apprehension on Toyota's part to cover my blower-induced engine failure! I envison it going something like this, "Honestly, sir I don't know why the piston shot through my roof, I was just driving to the grocery store..." Toyota's response, "Go fuck yourself."
I could just be ghetto and remove the thing if the engine blows!
Ok, so I am looking at the SC dyno results for the Tundra and it is for the 00-04. I wonder what it is for the 05+?? I wonder what the max boost is too. Damn it, now I have to call the bastards...

ROTFLMAO!
Laughed out loud at this!I have the 04 V8 LTD 4Runner. Been trying on another board to get same answer: Can I use the Tundra kit, and what are the "right" tweaks/settings to not blow the engine.
Heard horror stories (read posts, no first hand knowledge) about the weak rods in this engine blowing up...
Let us know what you hear when you talk with them about using the Tundra kits with 4Runners.
Thanks!

The horror stories are true for people who decided to up their boost. From my research the 2UZ-FE should be able to handle 5-6 lbs of boost reliably, which is what this kit is essentially providing.DiskDoctr said:ROTFLMAO!

Cool!
I've been watching the URD SC kits for a while, but without knowing if it would work well in 4Runner...
Did I read that we'd have to custom fab an instake?
I saw this one and liked it a bunch
http://www.toyota-4runner.org/showthread.php?s=&threadid=17375
Don't know if he is/is willing to make more, though? I'm new at this site (lurked and read for a while), and don't really know anyone yet.
But that's the TRD version, I think pulled from the market? Which is better?
Anyone else make these?
Any pros/cons of using the Volant CAI with the SC?
(We just installed SC on buddy's Chevy truck this weeked, and now I'm really jones-ing
)Sorry for all the Q's...
Thanks!

it look like the URD unit comes with a programmable ECU so you should be able to program the fuel map correctly for the 4Runner.
Looking at one of the 2wd dynos on the 03-04 4Runners we are losing about 18% drivetrain. Since 1-bar e.g. 14.7 lbs of boost usually equates to a 100% gain in power a little less for the SC since it is parasitic.
Anyway with the TRD SC at 7-8 pounds the posted gain is 118 hp and 100+ torque.
In my experience at least for the TRD SC's using an intake increases the air which increase the power which increases heat soak which can decrease power, unless you tune for it or use a WI kit since there is no intercooler.
Anyway good luck.

Looks like its a Powerdyne Centrifugal S/C:Casper said:

I don't think a roots type blower would be good idea on a stock engine, especially not a V8. It is thermally inefficient and would be of no benefit for a V8 engine because roots-type superchargers produce their max boost at lower rpm's. That is what makes them more desirable to drag-racers and for smaller engine types.

the TRD IS a Roots type.

the only thing I can figure for TRD's reasoning is that it was a one piece custom made for TRD with little to no fabrication for installation. They probably figured they would go with the system that would net them the most profit with little participation on installs and tech help on their part which you'll find very true when you call them and ask them anything about their SCs.
Anyway the extra power in the lower end make for spirited daily driving and is ideal for towing, the centrifugals are ideal if you plan to stay in the mid to higher rpms. it is a matter of application.
