I was wondering how much more NA power do you guys think this engine is capable of? Good parts tune and losing some of them MPG'S.
Does anyone know of a sick '12 Si pushing The n/a envelope yet?
I know they are relatively new and in high HP setuos turbo is the way to go, but I am really curious!

 

Go to 9thgencivic.com you'll get a lot of info there, but for a start up the k24 has a lot of potential ....

 

I found 9th gen civic.com thanks man.
