is 93 that big of a deal when running boost?? unfortunately i have used 92 gas for the 2400 mile duration of my life so far, the 93 is a bit difficult to find. possible, but difficult while the 92 is normal.
can you clarify what you mean when they eventually require a rebuild? is this based on miles or years, or based on maintenance of how hard i drive the car??
thanks for answering btw, i understand noobs such as i can be annoying on forums.

92 is fine, remember that it is essentially an anti-knock rating, so the less octane, the less timing/boost you can run and keep the motor from knocking. The Subaru ECU has some fairly modern anti-knock mitigation code in it that helps keep your car safe. Turbo rebuild intervals can have a lot of factors such as the manufacturer of the turbo, design of the turbo kit and what oil you use, what psi the oil flows through the turbo, how well the drain line is setup, what temps the oil is run at, and how well you are filtering the air entering the turbo. Superchargers are generally just oil filled, so there is less too worry about other than doing the scheduled oil changes on them although the Rotrex kits do cool the supercharger oil. The seals and bearings still wear in them though, so they also will require maintenance/rebuilds. I haven't researched what Vortech or Rotrex's expected intervals are for that.
