SO i am looking at a single rear mounted turbo setup. I dont have room in my engine bay and really dont want to deal with the plumming of 2 turbos etc... I plan on doing compound boost into the KB 2.1... my question was a large single turbo.. do i need to run both header banks into one 3" exhaust pipe to feed the turbo in the rear? I have an H pipe with dual exhuast right now.. I plan to leave the dual pipes in the back as its a rear valance exit now and looks so clean... I am looking at about 5PSI with the turbo... but need about 1500 cfm...80mm turbo??
