    Steer away from the Professional products intake. It uses paper gaskets on the intake to head seal and if everything isn't perfect you will have vacuum leaks. A BBK would be nicer but I'm thinking that since you're going to have a turbo on there one day in the future, leave it be. I'm not sure how much dynamic compression changes with boost but 9.6 cr with 10 psi of boost might be doable. Quik, do you happen to know?

    Since there is a 90mm Jtube modification for the Radix setup, I would guess yes. Anything to help breath better has to be good even for SC's FI setup in the future. I'm not sure it has much benefit on low boost turbo applications though. More research would definitely be advised in that situation. Since the Radix has to pull air through the system the 90mm Jtube sounds logical.
