I have the Moroso unit on mine. I cut the -12 connectors off and welded some -10 bungs on so as not to need the adaptors. I'm currently looking to find a better front crank seal to run the system closed under vacuum. With the passenger side inlet plugged, the engine will generate 6.5" of vacuum. Only problem is that when the engine gets up to operating temp, the stock seal will only hold about 5". When it loses vacuum, it squeals like Ned Beatty in Deliverance. Hence the quest for a better front seal. I did drive the car with the 5" of vacuum, and there was a noticeable difference in performance.
