i have a 2003 lancer oz manual trans. SOHC 2.0lt Engine, ajen cool intake and thats it.. i bought the car used 8 months ago and the only thing i've done too it is clean the air filter and oil changes. basically i just want more punch when i take off.. my 0 to 60 is like 6 or 7 seconds. not to sure cause i never clocked it but very slow. im wondering what i could do to get it off the starting line a little faster. im eventually gonna get catback exhaust and headers but i really didn't want to do to much work on a SOHC.. but i was also told that i couldnt' put a DOHC in my car becuase i would have to change out the chassie and mounts and it would become very expensive and better off buying a used evo.. any advice?
