do you and your engine a favor
check air intake system for restrictions, stick on a subspeed kit with uni filter
check ignition system for proper performance, change cap and rotor to napa premium made in japan, switch to accel 8140c coil -- but keep the old one, and the #1 thing to do is put in NGK BPR6EY-11
check the fuel system, change the filter to a pruolator, inspect the fuel lines
install quality vac/boost guage with small dia line, 1/8" iirc, hook the line to the port on the intake manifold that has a square head plug in it
if the line is larger or longer than necessary, there will be unacceptable delay
use a short hose from wastegate port to turbo outlet port
inspect the cooling system, make sure you use a NAPA SUPERSTAT or genuine subaru thermostat of the correct temp. with jiggle pin
change oil, filter, and drain plug gasket use a high quality diesel engine rated oil, CH4+ is the "current" rating, do not skimp as the turbo and hlas will suffer if you do, you should be able to run 15w40 or 15w50 year round but adjust as needed according to climate AVOID FRAM oil filters, they are JUNK. PUROLATOR and WIX are good, along with their private label brands, the "ADVANCE AUTO" AA3600 filter is a PUROLATOR in a red package with a textured outside to hold onto, and when you install the filter, put the bejeses to it, otherwise it may vibrate loose and pour out oil
BUY CLEAN FUEL AND KEEP IT CLEAN E-85 will work fine if you know what you are doing and how to drive with it it helps if you have 2g of regular to 13g of E-85, but adjust to your particular needs E-85 will give you the capability of making more boost with stock turbo and exhaust, even with significant exhaust leaks if you want to watch AFR, buy a lambda system
