alright so i am getting an lr4 (06 gen 3 but has ls2 rods, all ls's had ls2 rods after either 2005 or 2006) with 96k on it and he sent me a vid of it running. now what im wondering is should i get an ls1/2/7 intake, what fuel rails (FAST ls7 rails?) (running e85), what injectors (i know ill need 80#+ injectors for e85) should i run twin inline walbro 255 lph fuel pumps (external pumps) and what should i do for ecu? should i keep the stock harness and computer? and is gapping the rings necessary for 8-12 lbs of boost on an s475?

At some point you will have to make your own choices, based on what you want to accomplish.

You should gap top rings to at least .035 and second ring to at least .038 to avoid braking the top of the pistols at high boost for any drift car application, drift cars are much harder on pistons than any other application.
