I have searched, but only found info about the ZE. Though I found that I can change cams, pistons and IM to ZE, but that will be too expensive.
How about change the throttle body? Guess it will not add that much power, just throttle response.
I have changed exhaust system after the cat to 2.5". Thinking of new headers. Is it worth the money, and how much will I gain?
And here's a pic of my honey
