I have a 2004 honda civic with injen cold air intake, magnaflow cat-back, body kit, rims etc... I was wondering what would the next performance modification i should make? please help me out, i need more power. and speed.

 

header? lower it? short throw shifter? intake manifold with lager tb? u'll get better performance out of these but u wont get any more speed than the car already allows..

 

turbo!!!

 

i think it is lowerd...you started off pretty good, what are your future planes? turbo? SC?...once you figer that out, you can start building for it

 

i agree what are your goals?

 

I say short shifter will be your cheapest performance mod you can do.

 

a turbo would be nice but thats a lot of $$$..i say go with a intake mani and tb.
