Offset twin turbo sizes..????

What are the hurdles in this.??? Lets say a 60 for quicker spool for one side and a 70 for the other for some more topend... This is just a thought guys so keep flaming to a minimum.....

Backpressure is not equalized on the turbine side. So basically the engine will be fighting 2 different forces.

Not enough room to run sequential turbo's efficiently in these engine compartments

Could this be remedied by using different exhaust housings and wheels....????

No, but it could be remedied by using two properly sized turbochargers.

A pair of PT61 P-trim .68 A/R turbos will do over 1000 to the wheels without maxing them out, and will be fully kicking by about 4000 RPM's. What more do you want?
