I thought centris and turbos had very similar power curves... outside of the exhaust, I don't get what else you'd have to change to prep the rest of the car for one or the other.

No way. The blowers are similar in vane design on the air side, but the turbo gets up much quicker than a centri. Figure max boost from about 3500 to redline with a turbo and max boost with a centri is max rpm.
