I agree on the swap, but IF your asking which would be better?

A supercharger= better on takeoff, getting jumps out of holes, or turns.....

A turbocharger= better in longer distances when it has time to spool up, now you can get it modded to spool quickly


all in all, in my opinion, depends on setup/what you want the car to be used for....in my experiences, a super charger will mostly always get a jump out of the hole on a turbo charged car.....
but a turbo will always beat a supercharger in the long haul....

but yeah, id say for your particular car a B18C1, or C5, then decide
