Oi Rice,

If you were to use an oil return scavenge pump to allow low mounting of a large turbo like one of those s400s (like really low touching undertray in front/besides engine), would there be enough room in the engine bay to high mount a s300 turbo pointing backwards tight next to the block, feeding (in addition to "primary" wastegates) into one of those s400 mounted low in the bay at the front with dump running under the exhaust manifold/smaller turbo? Would be nice to run 36psi from, what under 4000rpm to 9000rpm, I'm guessing due to the wider peak boost range you would want to run 2 stage pre turbo injection with a 50% flow rated secondary injector to come in before peak torque?
