performance mods 7th gen Civic
 

How much can you hope to punch up the HP in an '03 to '05 Civic EX coupe by adding the cold-air intake, aheaderand catback? And does imake any sense to change the throttle body if you do nothing else to the engine internally? Also, what about achip? Is thereonethatgives you a little more punch without drastically changing the characteristics (easy starting, good mileage, etc.) of the engine.

Also, since I'm notbuying anything until this summer, I was wondering if I'd be better off with an RSX (not a Type-S)? Was thinking of changingthe exhaust system and adding the intake on it as well.

hmmmmm...03,05,02,01 doesn't matter which yr..7th gen vics got the same engine. now interms of power you don't get a great outstanding leap unless u do a swap ((k series anyone??)) or turbo. if ur looking for some nice respectable gains.
nice idle on engine. aem pulleys
a few more hp to the wheels...aem camgears.
nice throttle response and high end gains...get aem v2 intake and a nice exhaust setup. whatever size tip that set's you on fire is ur choice.
greddy, apexi, tanabe, are just a few great names to look into.

or you can just get the rsx, much better car & already comes with a great amount of power, but not my style interms of looks.
whatever you decide Gluck.

It's either that or around... maximum 25-30hp...

Search!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ibtl....

I always thought it was more like 5-10whp if youre lucky for i/h/e

better off with rsx

8thgen Si

ya ur better off with a 8thgencivic

better off with a search

put it liike this....i got 163hp/160tq off a 1st time sprayin a 50 shot dyno run TODAY. That is with a rough tune...should get 10 more roughly....look at my profile....125hp with out juice...i got big brakes and wheels tho...more like 135-140 with stock steelies and brakes on NA, and 175 ish hp/tq on spray. That is without building the bottom end. stock my lx put down 95hp 90tq....to 135hp/128tq....with all mods and aboiut 4 hrs dyno tuning now. Take it as you will....I learned alot but i would not do this much on a soch engine again. go with intake, pullies, AXLE back exhaust, emanage, full exhaust if sprayin. and nitrous if you want a good kick to suprise someone with. These mods were the only engine mods worth it to me in hind sight. Just my $.02 otherwise strap on a turbo and enjoy.

mods + d17 (our engine) doesnt work.

forget about it, no matter what exhaust, headers, intake, you put, your not even going to gain 15whp

ya i agree with gearbox but it would be sweet to build your motor up
