Norris designs is making that super charger / turbo. The supercharge is on the back side of the motor towards the bottom. he said that if it works out the kits should be about 10K.

madmac's evo running hillclimbs
runs a supercharger and turbo 6krpm rev limit (set as a test can rev higher) but there is so much torque he didn't need the revs

A guy on the forums tried this idea. He had a 1500 cc charger with an HX50 turbo. The car did amazingly well until that his tuner didn't have experience and AMS wasn't sure how to handle a setup they didn't build.
I have always thought twin charging would be a good idea. I hate seeing twin charger setups that use a centrifugal and a turbo would much rather see a roots charger.
On the topic of tt setups I say do compound instead sounds little easier and more efficient from what most diesel guys say.

You will get a whole bunch of EVO 'experts' claiming that your question is totally ridicules. "Two turbos is one too many." "Look at the RX-7." "Look at the Supra."
My response to the naysayers would be, "Look at the Bimmer 135/335." Why is no one laughing at BMW?
That said, I think a better set-up idea -- with far less plumbing required -- would be a compound turbo. Basically that is a small turbo blowing into a large turbo. The best of both worlds -- very quick spool and very big HP.

And ams was going to do it in their top shop challenge but according to modified they dropped the idea because of cost and went with a single turbo.
It can be done. Anything is possible u just need pockets deep enough.
Here's more food for thought how about a twin charged evo? Why have two small turbos like the original op said or a small turbo feeding a larger one. It would be sick to see a supercharger handling everything down low and a huge turbo taking over up top.

The AMS setup looks compound at first glance, but was actually sequential. People have compounded turbos and super chargers, but the problem I have with that is that the SCs most people would use for this are pretty inefficient, and compounding it will just compound the inefficiency. But it does work, and people have been happy with the result. One benefit is that since the SC is tied right to the crank shaft, spool up is predictable. In a case like mine with an auto trans, that would be beneficial. The spool up on my small turbo changes with the conditions, which can be somewhat aggravating, but once it spools, it spools the big turbo with no problem and ultiamtely that's the main goal.
