I've had the 3076 kit for almost 2 years now. Aside from having those PnP injector clips keep failing (It's causing misfires again), it's a very solid and fun kit on the streets. Like others have said, it's not simple or cheap converting to E85. And if I had the chance to do it again, I'd go with the 3582. My last dyno registered 340whp.

 

Bump

I've been lurking in the FI forum for a while. I almost pulled the trigger on the new KW supercharger kit, but wanted to do more research on turbo kits. I'm more interested in the overall simplicity and "OEM-like" quality/fitment of the SOS turbo kit rather than its high HP potential. I'm also surprised that there isn't more reviews, dynos, etc. available in this forum and on other sites. I'm sure I would enjoy this kit, even in a low boost application; however, I don't know if the price premium is justifiable...

 

What would you guys say is more responsible for the quick spool of this turbo? The fact that it is twin scroll or the fact that it has a very short manifold?

How would this kit compare to something with a log manifold all other parts being equal?

 

Have a twin scroll design and have short runners are both important to spooling the turbo fast. But I would say the twin scroll desige has a bigger effect.

Given the same exact turbo a restrictive log manifold like a rev hard or inline pro manifold would spool slower and make less power than the sos kit.

 

I have the sos turbo kit.. It was rainh8rs
I love it... ish

Here is my take on this.

It's the atp devided housing on the turbo thats causing the issue. Not the manifold bends.
The turbo is a stock location replacement for evo8/9

^thats the turbo that I have, its not identical tho. Not the one with the big inlet.. the one with the small, 2.5" inlet.. that says A/R.50 on it, except w. an 11blade compressor. Try finding a compressor map for that... you won't...

SOS advised me to run e85 since the turbo is a 'high pressure' turbo. How ever, if you jump over to the evo forum, there is a fella on a stock location GTX3576r claiming 550 hp at 32psi on e85. http://www.evolutionm.net/forums/dra...l#post10662774 meh..

I'm currently on a street tuned, modified version of rainh8rs 15psi, dyno tuned map. Hopefully sometime this summer, I can make it out to Evans. I would LOVE to see what this kit can / will do after the man is done w. it.

The low end power is fantastic, there isn't really any lag, unless you are below 3500 rpm. I personally don't feel the power flat lining, or tapering off. I haven't had a chance to go up against anyone either, so I can't really report anything as far as numbers or where my car sits. I do like the divorced style downpipe. Im currently running a berk header back exhaust, and the car is very quite at idle. Here it is under boost. https://www.youtube.com/watch?v=wQd_...ature=youtu.be

Here it is with no exhaust and just open downpipe https://www.youtube.com/watch?v=EM17eJKPSjE

What I don't like about the downpipe is the flange...... It's a larger flange than stock (I'm not sure on the numbers) & my Berk was made to work with a stock header. So the huge donut gasket that came with the SOS downpipe just won't work with aftermarket ready options. You will need something fabed up. I contacted SOS & Berk about this.

The oil filter relocation piece is nice, except for the fact that its cast aluminum with a tap that has about 4 threads, & your turbo feed line connects to it. After some overnight teflon coating, its good to go. I contacted SOS about this & suggested welding the fitting instead, they said it's not a good idea to weld the fitting into the cast part. Idk much about welding, so w/e

SOS site calls for an air intake temp sensor kit, thats "required" for MY00-MY05, which I purchsaed. Rainh8r informed that I don't need it. I thought I would do it anyways since its SOS recommended & I wanted all the supporting mods that the kit required. Upon arrival, it did not come with a calibration chart. Turns out there isn't one, & its for the AEM ECU's. Which does me no good, since I am using Kpro.

Fitment is tight, squeezing the turbo w. the manifold on it was fun haha, but once it was in, everything clears. No issues on that.

I wish SOS would provide more info on the turbos they offer & dyno graphs for ALL of them, not just 3 graphs, two of them being the same turbo on different fuel..

What else would you like to know? I'm glad this thread is here, bc I too, feel that there is little to no info on these kits.

 

Well, sorry to bring this back up since it's been about a month since it's been active. But I was wondering, how come no one's thought about using a Borg Warner efr series turbo in place of the the garret ones provided by sos and just fab up a down pipe for that turbo? I'm sure it's more complicated than it sounds but I'm too lazy to find the differences and why it would or wouldn't work. Besides knowing one would hate to have to go through the extra costs to get it done or just investing time to see if it's possible.

 

I think a slightly modifoed FP turbo would work.

 

Turbos are different flange styles and the efr would be to large to fit in the small area used by the SOS kit.

 

There are many reason why this would not work

1 borg Warner turbos are physically very large. The compressor covers are much larger than a garrett or precision turbo of the same size. Borg warner turbos will not fit in an s2000 with a side/bottom mount manifold such as this SOS kit or a ptunning or even the full race ram horn manifold

2. The SOS kit uses a garrett turbo but instead of useing a standard garrett t3 or t4 turbine housing they used a restrictive atp turbine housing with an evo 8/9 style mitsu divided twin scroll flange. No one makes an evo 8/9 style flange for a Borg Warner turbo.

 

Gotcha!! Thanks for the information.
