Yes you should be able to. We flew in Clark Turner from AZ out to Dallas last weekend and there were a few 18g 2.5L WRXs there. Our gas is better but I think it will be possible if done right.

If you asked mike that, why didn't you ask Mike this question? He should know more than anyone too.

did not cross my mind at the time.. i was just concerned with how much to install and what i would need. not till i got home did i think of how much power i would get. im choosing it because i dont want to upgrade to front mount and i want something better than stock. i dont really care about numbers i was just curious

In all honesty, I wouldn't bother with an 18G on a 2.5L. I'd either go VF39 or step up to a 20G.

Properly tuned on an 'average' reading dyno 300whp shouldn't be a problem, on GSTs dyno which I think is Gruppe-s' old mustang dyno, I seriously doubt you'll hit it on their dyno.

You need an FP Green to break 300whp on that dyno.

you need an fp green? i disagree...... i have a 20g.... ( i know , not 18g ) and i made 310 on gst's with an injector leak, boost leak, too small of a maf housing , and my crappy stock bcs....... so i believe its possible....
