Why is it that you'll fine if you stay out of boost? I learned something and just wanted to share this.
"The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. Knocking can damage an engine, so it is not something you want to have happening. Lower-octane gas (like "regular" 87-octane gasoline) can handle the least amount of compression before igniting. "

I've been out in the toolies where the only available gas was 87 octane. I took a full tank, the car ran, no audible knock, nothing happened except less power.

Why don't you just drive it down to about a half tank, then fill it back up with 93? You'll definitely be fine then. Either way, you should be fine, unless you're tuned close to the edge on 93. I go from 93 to 91 (shell v-power) and it's not an issue.

if you cant afford at least 91, dont bother driving the car..... theres a reason that the fuel door has 91 + on it........
Why stop there, just use synthetic oil every other oil change , instead of using it all the time......
And stop buying manuals from crackheads on street corners....

From the manual
FUEL USAGE STATEMENT
CAUTION
Using leaded gasoline in this car will damage the
catalytic converters and heated oxygen sensors,
and affect the warranty coverage validity.
This vehicle must use unleaded gasoline only.
This vehicle has a fuel filler tube which is especially
designed to accept only the smaller-diameter
unleaded gasoline dispensing nozzle.
The 2.0L model is designed to operate on unleaded
gasoline having a minimum octane rating of 87
[(MON + RON)/2], or 91 RON.
NOTE: .
• MON: Motor Octane Number
• RON: Research Octane Number
GASOLINE CONTAINING ALCOHOL
Some gasoline sold at service stations contain alcohol
although they may not be so identified.
Using fuels containing alcohol is not recommended
unless the nature of the blend can be determined as
being satisfactory.
Gasohol: A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used in your
vehicle. If driveability problems are experienced as a
result of using gasohol, it is recommended that the
vehicle be operated on gasoline.
Methanol: Do not use gasoline containing metha-
nol (wood alcohol). Using this type of alcohol can
result in vehicle performance deterioration and damage
critical parts in the fuel system components. Fuel
system damage and performance problems resulting
from the use of gasoline containing methanol may
not be covered by the new vehicle warranty.
GASOLINE CONTAINING METHYL TERTIARY
BUTYL ETHER (MTBE)
Unleaded gasoline containing 15% or less MTBE
may be used in your vehicle. (Fuel containing MTBE
over 15% in volume may cause reduced engine performance
and produce vapor lock or hard starting.
MATERIALS ADDED TO FUEL
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain highly
active solvents or similar ingredients that can be
harmful to gasket and diaphragm materials used in
fuel system component parts.
