I'm courious about difference between these turbos. I did a bit of searching (hey, the button works!) and found this from The1Bill a while back:

"I brought up the exhaust housing because it is the telling part of the s16G. The fact that they are using a TD05H wheel in a 10 CM^2 housing instead of a 7 CM^2 or 8 CM^2 housing is the biggest difference between a S16G and a Large or small 16G. I am not sure what compressor wheel is being used, but the compressor housing is different. Therefore, they are trying to say that the 10 CM^2 exhaust housing is responisble for the difference."

So, I see there is a difference in the exhaust housing. Like an overbore or something of 2-3CM^2. Am I correct? Anything else?

As far as I know, the only difference between the 16G, and S16G, is the exhaust housing. Super uses a 10cm, where as the 16g uses a 7cm. The compressor wheels are the same. So basically the S16g will have better exhaust flow, and get rid of any boost creep issues that can happen with the 16g. I believe they both use the TDO5H turbine.

Thnx Xtreme. That's all I was looking to know - question answered.
