yep, from this site (great info on differences between japanese, world, and us wrxs) and others I think you would need 100 octane minimum to keep it from detonating and to get the full power out of it.

Very informative site, thanks Snowman

Nubs a quote from the above mentioned site
"WRX EJ20G hydraulic lifter motor with a 9.0 compression ratio up rated to 250hp. For 1997 this hydraulic lifter motor was modernized with the new style intercooler and intake runner of the EJ20K."
Being the one I got is a '95 I'm guessing that the older ones had the "air to water intercooler" before the air to air ones became as popular.

Ron, uuhh.......no.

Snowman, It probably won't produce the max HP on our gas, unless I run racing fuel through it, but the computer will retard the timing to make it run on our gas(91-93 Octane)and still make good HP.

I mean the Outback Sport only has about 145 HP and the XT6 only has about 145HP, so even if it just makes 200HP it'd still be a huge increase, and I could always use some racing fuel if I really wanted to play with it some.
