All turbo heads **Please Read**

I'm really curious about any turbo kids and their take on the feasablity of this kit. Could this turbo set-up be legit and does ANYONE see problems with this. I got my fair share of questions as far as bottoming out, oil feed lines and oil pressure, massive tubing to the throttle body.

Check out the site:

P.S. I know this isn't the right category but a couple of turbo kids I respect are typically found here at the Camry section of the forum. So, I'd like to hear their take on this setup. All in all, it's pretty unique and is very interesting to me.

hmm.....interesting. never knw you can do that. if only i was in the USA i'll buy 1.

There was an extensive discussion about the STS kits in this thread: http://www.toyotanation.com/forum/t77705.html (where I made my opinion very clear, haha)

To reiterate, here are the highlights:

For one thing, the oil lines are about 20 feet long, and you need a pump to run the oil back to the pan. Bad idea. Then you have the exhaust pipe that runs all the way to the back of the car, which means the exhaust gas is a LOT cooler (less volume to spool the turbo) and it will take forever to get it going. Then, the turbo has to compress 10 feet of charge pipe all the way up to the front of the car before it goes into the engine, again, major boost threshold there. And they don't include and intercooler because they claim that the long piping cools the air enough (partly true, not as good as an intercooler though). Then there's the issue of it being damaged, or better yet, how about a bunch of cold water getting sprayed all over a hot turbo after going through a puddle or something? Oh yeah, good idea!

I guess I wouldn't be so against the whole thing if STS wasn't always trying to market their kits as if they're 100 times better than a conventional turbo system. Yes, this type of kit DOES HAVE ITS PLACE in the performance world, but it is NOT the ideal setup.

The only time I would use anything like this would be where there is no, and I mean NO room in the engine bay for a turbo. Usually a battery relocation to the truck will make room though, if you can fit the piping in there. And even then, I would try to find a better place than ALL THE WAY at the back of the car.

That's the Doc's three cents (inflation), feel free to disagree.

• Let's see what you think is more important to spooling a turbo A) Loosing exhaust tempature, B) having 40-60psi of exhaust pressure, C) Picking a descent sized turbo to be spun by your exhaust pressure. Oh wait!!! You chose A!
• Hey!? Ever taken your mouth and blown into an intercooler!? That's no worse, if not a lot worse in terms of restriction than jsut a long pipe... I'd pick water injection over an intercooler if I had to pick between the two to begin with.
• Dude... You just said, OH MY GOD THIS THING SUX0RS!¡! IT'S NOT AROUND THAT WICKED HOT EXHAUST!¡! 10-1 Says the turbo would only be 100*F hotter than the stock muffler.

On ANY turbo system where you're unable to mount the turbo DIRECTLY to the manifold what do you have to do??? Route the exhaust down, down, down, then up! Up! UP! If you have an engine with multiple banks, you have to Y THE PIPES TOGETHER FIRST wasting even more piping, fabrication, and spool-time.

Wait here's a pop-quiz kiddies!!!
By the time you've done that, then plumbed all the way back up to the battery location (typical install place, for an aftermarket system) How much pipe have you used???

Almost the same amount to GET to the tail pipe.
"Oh well then it's still shorter"
No... You're trying to force exhaust around crazy bends & twists, while what is the exhaust doing on theirs??? It's running a happy marathon through straight pipe.





Guess I'll take the other side of the arguement.

And what about the location of the turbo? You didn't address that.

That doesn't mean that one of these days I won't put one of these kits together myself and test it out. I don't mind being proved wrong.

Oh and to water damage quesiton Dr. Tweak, it's not too hot that far from the manifold...low fear of cracking from a little water spray. My largest concern is oiling...that's a long way to truck oil, and electric pumps are far from the most reliable way to move automotive fluids...

This is from someone that does play with turbos: You won't notice the few percent difference 99% of the time anyhow. Here, as an example, if you were generating 300hp with the ideal underhood location, I would anticipate you might lose 10 hp with the tail end location, and perhaps 150-300RPM of spool time with the STS setup. Lets put this in perspective...the efficiency losses may result in 1-2 tenths at a drag strip, forget the little bit you can step on it on the street. Most of you probably lose 1-2 tenths from using any or a combination of the following: cheap cat, cheap rubber, an OBX air filter, 80lbs of stereo, forgetting to remove the spare tire, running a full size batteries, having more gauges and lights than a 747 cockpit etc...as no one here is running a pure race car on the streets, you have made compromises that cost you performance...this is a compromise too...and not a bad one.

wow.. didn't read the reply yet but THANKS for puttin' it all up bro You gotta love TN

edit:
I just read anything and the biggest argument was both the lag that must occur and running oil lines. I'd hate to have my turbo seize up when my oil pressure fails. Plus, that's alot of line to run oil through. I just.. I don't see it being reliable but regardless of that, take a look at the vids, it's sweet to see how unique this thing is though....
