Kind of agree but the man hours involved in de-modding current rig just to move goodies over to WTi doesn't make sense. Would rather plop 10k down for 100 extra HP.

The bullet kit uses some cast parts they have made, yes you could make the inlet, and the water outlet is just cut and turned to miss the drive, but the time spent to do, you would be wanting to recover $ invested too.
Tuning the 4.7 is also not for the feint hearted, as the rods are like pencils, and timing it ever so incorrectly, and they bend.
The supercharger is an Eaton unit.
We have installed and tuned these kits, and around 215kw at all 4 wheels in an auto on 305's is the norm with intercooler and headers and exhaust.
Standard they are around 105-109 rw kw here [no vvti here]
Tune, exhaust and headers they go to mid 130's rw kw.
Customers whom have had it fitted and tuned at work seem to average mid 16 lt [4 us gal] per 100km [64miles] hwy with load and acc, and 19-22lt per 100km on desert our outback trips.

I could buy a lot of strippers and cocaine for the cost of this.
Nice gains; but it sure seems like a ton of cash for a blower...
Maybe expensive but not too much out of line with what's out there. The TRD SC kit was about $4500 back in 2003. If the US/AU exchange rate was back to 2008 rates, this would be in the $5000 range. The current 5.7 TRD SC kit is around $6k.
Something to drool over.But that comment on the rods being pencil like worries me. In the long run seems like it may be too much for the engine. Any long term tests? MIke
starting to save up your two cents there Mike?
I was thinking about buying an 80 to play with but I would seriously consider doing this instead if there were some positive long-term reviews out there.

The TRD SC 4.7 is quite difficult to get.
I believe I read here in this Forum that TRD stopped the production for the 4.7 because there was something wrong with it, maybe it was the bearing if I remember right.
I ask TRD in Dallas to get me one 4.7 TRD SC. They replied that they could not get anyone!

Kit looks good, but it is $$.
Has anyone done a 5.7L motor from the newer tundras/sequoias in UZJ100?

I understand the whole SC in a sports car. What is the draw to our rigs? I mean a fully built rig is going to run 7000-8000lbs. The places we take them are off the beaten path and "usually" at a pretty slow pace. What is $10K in an SC going to do that I cant do with my current rig, some DT headers, and a better exhaust?
And I am serious with my question. I dont understand what this gains us for off road. I also believe if you have the money to spend... then you should do what ever makes you happy. I have just been watching this thread and finally had to ask.
Thanks!

If memory serves, TRD stopped offering the supercharger for the 4.7 because of the piston rods on the U.S. made engines. The U.S. 4.7 rods are cast parts and already near their safe limits at stock HP. The extra pounding introduced by forced induction was breaking too many Tundra/Sequoia engine rods, so TRD pulled the supercharger of the market.
The Japanese manufacture 4.7s in our LCs/LXs use forged rods that, while still thin, were generally strong enough to take the extra load of the TRD SC. I suspect they would have kept the supercharger on the market longer if all the 4.7s used the stronger forged rods.
There's always aftermarket rods like the Lexus folks do with the 1UZ and 3UZ engines.

Considering the weight of the LX 470 the power on my LX 470 (235 Hp) was for me a little too low.
This nice 4.7 liter engine can give more power.
Alone with the installation of the Unichip the power increased already. It felt like the engine was waking up form sleep. This was at least my Impression.
However, with the Supercharger, DT headers and the taylor made exhaust (including Y-Pipes) it is a different car!
My car (LX 470) is Japanese Specifications. Maybe than the rods are ok?
However, what I can tell for sure is the gearbox. The gearbox oil gets too hot; therefore you have to install a gearbox oil cooler. Without oil cooler my gearbox got overheated and was damaged. Big Repair!
With the oil cooler the gearbox has no problem at all.
I do not know whether there was any gear box issue with the TRD 4.7 Supercharger existing?
It would be interesting to know.
Thank you.

The rods are fine, as long as the timing isnt overly aggressive especially at cruise, low throttle position.
Some of our customers are 8-9000# with 305 tyres, roof rack, bull bar, winch, rear bar, storage, and expedition touring, and dont mind playing in the dunes occasionally.
The 4.7 definatly needs an intercooler.
As for why, .... why not?
The vehicle is much nicer to drive, more fuel efficient, much more low down torque, and that nice little whine, as it idles

This I found why the stopped to make the 4.7 L TRD Supercharger:
TRD introduced a second supercharger for the V8 (2000-2003 models) engine late into its second year of production that pushed the V8 numbers to the mid 300 horsepower (220 kW) range and torque to the 400 lb·ft (540 N·m) range. Although the V6 supercharger is still widely available, the V8 supercharger is rarer and harder to find because TRD stopped its production once Toyota released the updated VVT-i equipped 4.7-liter engine.
Here is the Link

Looks like it has had nothing to do with any Problem! They just stopped after the new engine was released.

The 5.7L will not mate to anything that has the drops on the right side for the front and rear diff. Also the electronics will be a nightmare. A motor swap is going to be far north of $10k.
Anyone that has not driven a 100 series with 300hp at the wheels does not know why you need the power. It is a much more driveable, usable car.
