Frederic mentioned poor trailing-throttle response as a possible drawback
to this approach... I personally don't believe that, for various
reasons, but the thing I do worry about is having lots of oil sucked
into the air in the turbo. How much of a problem is this, really? I
know some turbo vendors have special sealing options avilable, but I'd
like to hear from people who have set any old turbo up with the TB
before it, if you had much problem with sucking oil into the intake.

The only reason I care this week is a weird turn of events has led
to the possibility that I'll get a turbo'ed car soon, and I'd like to
know, if I move the throttle before the turbo, how much trouble am
I asking for? Yeah I could get a new turbo/upgrade it/etc, but for
various reasons I would not like to have to do that.

   TIA,
