They have kits already for the V6 Tacoma and V8 Tundra.
So what do you guys think.

 

I'd go S/C first, look at all that ductwork!!!
The turbo needs to be much closer to the exhaust on the heads to be efficient.
I bet that system is not very efficient at all.

 

This was posted awhile ago and from what I read, not many people would be interested in the kit because of the location of the turbo.

 

I don't think I'd want that, even for a street rig. Why?

1. Location of Turbo... not only is it odd, but it leaves the turbo out in the elements, along w/ the air cleaner. Can you say water ingestion?

2. # of bends in the piping. For every 90 degree radius in piping, you lose 1 psi of boost. For every 24" of piping you lose 1 psi of boost efficiency. That means that poor turbo is working OVERTIME to make just 6 psi. That translates into poor efficiency, and excess heating of the charge air.

3. Did I mention that it's a piss poor location for the turbo?


While I have no doubt that the turbo system from STS produces it's claimed power, it's not a well thought out kit.. ESP. for a wheeler...

im kinda curious about this kit as well. they claim since they place the turbo under the car away from the motor, allowing the turbo to dissipate heat better, allowing them to run the turbo efficently without an intercooler. i thought the same thing at first, like wtf why put the turbo there. but all their turbo kits are like that. really its interesting stuff.

 

Weird...

I don't understand thier overall thought process if they are trying to compete with the TRD supercharger... Not very practical mounting place for a turbo on an offroad vehicle. (You could pipe a small house with all of that pipe)

 

I guess there marketing it toward truck owners that dont see much mud action, and do more boat towing. I dont like the location either, but some of the benefits they listed are valid reasons.

Imagine installing a turbo in a conventional manner on that truck, new headers, brackets, ect, I bet it would easily escilate the cost another 50% of what it is now, not to mention the nightmare installation!!

Id go with a charger myself!

I'd say for the price of one of those kits, you could buy an Eaton M90 and fabricate the brackets to make it work on the 5VZ. You could also plumb an intercooler on the M90 if you so chose.

 

The same thing crossed my mind. How much would just a M90 be?
I would for sure be running an intercooler.

 

Why would you not just run the TRD unit for S/C?....unless you are dying for something unique.

A turbo could be fabbed up with a bit of work but a centrifugal S/C would be the best for an intercooler.
Roots style blowers do have intercoolers too but they are $$$$ and not as efficient.

Jamie, I'm not sure what the price difference is between the two. If the M90 is a lot cheaper then it might be interesting, if not then I would probaly also just use the TRD unit.

actually this kit is listed at 3495.00, but to me that seems kinda pricey considering you're just getting a turbo, manifold, piping and lines. but they do claim to be able to be installed in just 4-6 hours and put back to stock in about 2-3 hours. like i said its pretty interesting stuff, if you read the faq there.

 

First of all I don't trust any data from a Gtech Pro. I'd rather see numbers from a dyno.

If it does make that much power I bet the boost response is absolutley horrible. All of that piping will cause a huge loss in exhaust gas energy before it hits the turbine.

I think the supercharger is a much better route. The boost will come on instantly. For trucks I like to see the performance in the lower RPM range, My Z is a different story though!

 

wow... from what i know about turbos you want the heat to stay in the exhaust side and any wind wouldn't be enough to cool the cool side to make it any more efficient not even close to an intercooler. I can't beleive they would make something that makes less HP and costs the same as a factory warranteed option for the V8.

thumbs down like the rest
