nico, this is one of thoes situations where your gonna need to answer your own questions. as no one has tried and we all can only make educated gusses. you get to be the niel armstrong of sorts.

azn2nr for real, well i geuss i got to do then.

well this is what i am going to do there is a 1999 2.5l sohc motor for $250, im going to get it slap the heads on change the sprockets to my factory turbo sprockets, plum the turbo lines so i have turbo still, fix the intake manifold so it works with my car, then i will let you guys no if this swap can be doen.

So are all 2.5 sohc heads the same? I have access to some off of an legacy or an out back. does anyone know if the new plastic intake manifold fit these heads? they do flow more than the wrx heads correct?


AS for getting new valves for eith 2.5 or wrx heads, would it be beneficial to get two mm larger intake valves and only 1mm larger exhaust valves. would this produce better torque numbers like with the 22t heads? just wondering
