I've actually got an extra supercharged 3.8 motor laying around. Planned on rebuilding it and going turbo for my grand prix. Problem is you'd have to source a M90 supercharger from an australian holden where the inlet curves back around to face the front in order to get it to work in a rear drive application. Considering the power I'm getting out of a few basic cheap mods, the VX would be one hell of a sleeper considering its only 200lbs heavier than my prix. How tough are the VX's tranny and transfer case? The L67 is 240 horse 280 ftlb stock but in most cases people find that the tourqe is under-rated.
