FI is FI, no matter if it's SC or turbo. SC will give you a flatter, more even powerband, turbo will give you more high end and can put out loads more boost than a SC. Each has its own pros and cons. I'd talk to someone who has a SC and another who has gone turbo and ask them how often they've had problems. You also need to ask yourself whether you want to boost the shit out of your car (turbo) of if you want moderate boost with less maintanance (SC).
