hey on the WRX thing...
one thing is for sure...
all japanese cars stand to gain from more air intake (it's seems)...i did the same with my integra...aluminum air intake/litespeed with a K&N cone filter, and the car seemed to want to squeel off the line....before i blew my old engine, i could chirp in second gear (189,000 miles), and i have an automatic....that's pretty awesome...
but for the german road...i keep hearing from other techs that the m104 engine and m103 was designed to be rocksolidily balanced...with no real room to expand, unless you do something drastic to the heads, engine, etc... in other words...
the only way to get real performance out of these panzer tanks is to spend a minimum of 3000.00 (and that's a renntech racing cam and porting job)
