M90 Blower Intake for slant

What size turbo did you get? I'm not sure I buy into Mike's idea to use a turbo that's sized for a smaller engine. I used to run a Mitsubishi TE04H on a slant - it would spool up at 1,500 RPM to 10 psi of boost, and run out of breath by 3,000 RPM. Not good, particularly with an automatic.
