i have a 07 civic si im looking for away to get more power but dnt wanna spend alot of money

 

1) sell the si
2) buy a muscle car
3) pocket the extra 10k cash
4) trash talk imports!

 

you are about as helpful as a pussy for a gay guy.

OP, to answer your question for power:
the easiest, cheapest route is usually HIE
Header
Intake
Exhaust

However, I would put money in a bigger intake manifold, a cam(s), a pulley system, and maybe some suspension work. Handling is everything, but thats my opinion.

 

you've been in a while its IHE. ha

i heard NAZZ energy drink in the gas tank works wonders. sport bike guys are doing it.

and an adjustable head gasket works well. 2.4-2.6 layers

 

you know, I forgot about going the nitrous route.

throttle in a bottle is cheap- check out NX, ZEXX, or NO2.

 

you missed it.
