very clever, makes sense.. driving an ISV instead of an injector. Obviously I
want to tune the hell out of my car first and see how I feel about the idle
then.

whoops, I stand corrected on SDS then.  that does sound pretty ugly.

well it kind of has to for right now, it is up on a set of jack stands with
various bits (upper and lower core support, oil cooler brackets, etc) waiting
for powdercoat till' it hits road.
