A twin turbo engine puts far more complicated demands on the hardware than a compound charging, using supercharger-turbocharger, does. On a straight six such as the rb26det it will be fairly complicated in first place, due to the balance in volume that needs to be, considering both exhaust manifold piping, but also the pressure pipes need to be of exact characteristic. Besides this, the turbochargers must be of exact specifications as well as wastegates.
I am currently performing the design of the hardware architecture of a conversion such as this, to be carried out on a Cadillac STS 32-valve all aluminium V8-machine. Not a simple task i must tell you...
