the same principles would apply to both; a home ported or ported stock from a sponsor will net the same relative gains as a fast 78mm or bbk 80mm. they get by w/ the iac through tuning if i recall.

porting it, filling,and drilling the pcv vent hole will flow better.
and the pcm controls the idle with the butterfly, by slightly opening and closing it, instead of the iac motor.
