It's nice to see that there's a few others with the same insane idea as me. Although, I blame Luke, look what you started! I've yet to even I/C my m90, so I've been chasing down the right equipment to begin with.
My plan, rather than running w2a coolers and the like was to use a split a2a like they use on twin turbo setups (300zx) and routing the blower through one and the turbo through the other. This would save on space under the bonnet, aside from having two lots of pipework.
So, the idea would be Inlet -> blower, blower plate outlet -> I/C1, I/C1 -> Turbo inlet, Turbo outlet -> IC/2, I/C2 -> blower plate inlet (LIM)
I'm sorry I can't provide detailed schematics as my paint skills aren't too crash hot when using a touch pad, and linux doesn't wanna let me use my external mouse.
Does anyone see anything obvious I've missed in doing this? Would there be a need to have a bypass between the turbo and blower?
Next question... where's everyone getting these turbo manifolds from, or is everyone suddenly a wizz with the welder? lol
