377 Turbo HSR

Has anyone used the holley Stealth Ram intake with the Avenger EFI, HP EFI, or Dominator EFI, on a turbo motor? If so how easy or difficult is it to get setup and dialed in with the timing and fuel curves

My dream is simple
Twin T04e 50 trim 48ar
HSR, C950, roller 228 @ .050 with .499 lift weak spring 112LSA
random 180-190cc runner aluminum head
9.0:1 compression

under 6,500 RPM
600RWHP

displacement maths:
355 x 6000 / 3456 = 616 * .069 = 42lb/min naturally aspirated with perfect VE
so dump VE to 90% then jack the boost to 15PSI:
355 x 6000 / 3456 = 616 * .90 = ~1100CFM * .069 (turbocharger constant) = ~760 horsepower
should be good for 600RWHP after drivetrain losses, and compressor efficiency losses.
pump gas 93 octane just intercooler it.
Weak spring low lift for longevity, get a head with good flow @ low lifts and small enough ports to maintain velocity.

With the right transmission, I am thinking 700R4 2800 Stall, 9.5" lockup converter (go probuilt!) this would be a scary vehicle

now put it into something very light like a 240sx (2800lbs)
