I have often pondered building a staged turbosystem. IMO would be very good for the 2jzgte applications.
Build a manifold for a BIG turbo, one "wastegate" outlet would go to a small turbo, a redirect valve after small turbine feed port would direct all exhaust to the small turbine. Small turbine outlet would route back to big turbine inlet after redirect valve.
Small compressor would lead to big comp inlet. One way pressure valve at big comp inlet before small comp port would boost engine through big comp.
As RPMs rise the exhaust redirect valve opens directing flow to big turbine. Once spooled big turbo takes over. Wastegate controlls peak boost.
So, imagine my suprise to find this picture.
