Hello everyone.

I'm new here, I live in Brazil and I'm very happy to find so much info about 8th gen but there are some things that I'm not able to understand, that's why I have created this topic.

Recently I started some modification at my engine.
I have a civic si 2007 sedan.

HEADER + EXHAUST (Vibrant 2.5")
HONDATA
INTAKE (K&N)
TB Spacer

What else I can do that would increase HP and/or torque?
I don't want to use turbo or supercharger.
A list of items, a estimation of HP torque gain and price would be good.

I realy appreciate your help. :vtec:
Thanks!

Hey... Thanks!

Could you give more info on where to buy these items? Links, models and brands. A eBay link would be very helpful.

Thanks again. :vtec:
