ok.
so i have this o3 civic si and i modified it up a little, just the basics i guess.
i put in an AEM V2 intake and DC headers and a Tsudo cat-back exhaust. i was just wondering like how much HP that would give me. i wanna know what else i can bolt on or something. any suggestions or comments? thx in advance....

 

5-10whp tops. which would put you at 130-140whp.

bolt on a turbo. that'll be fun. oh and you should've posted this in the 02-05 civic section.

 

i know if i bolt on a turbo then it will be fun lol
but i dont wanna put in too much money into it so i dunno.
thx though..
5-10whp is weak...

 

you have a honda. deal with it.

 

hey its not bad for my first car.
i was just wondering what if i put in an ECU would it help?

 

no. you need something programmable. in your case a hondata reflash or kpro. and a setup worth tuning.
