First off I apologize if these questions have come up before.

I have gotten feedback from other K-Pro users on various forums with different setups, but I wanted to follow up straight from the source. I plan to purchase K-Pro in the very, very near future and can't wait! I have a CN Stg. 1 kit on my 02 Civic Si. As you know, the fuel system is completely stock other than injectors.


1. If i plan to stay under the limits on my stock A3 motor (I think 10psi and under), which size RC injectors should I look into purchasing??

ie. (RC High-Impedance 550cc or 650cc)

2. Would it be in my best intrests to upgrade any fuel system components besides injectors??

3. Based on those answers, which calibration may be a good starting point for me to start tuning from??


I plan to do a little conservative street tuning at first to ensure I'm safe until I get to the Dyno which shouldnt be long at all. I plan to target somewhere between 7-9 psi.

Thank you very much,

The 550cc injector is a good choice. 440cc injectors would be getting close to their maximum and 650cc injectors would result in slightly worse driveability.

Use the Greddy Civic Si calibration with 550cc injectors as a starting point.

Thank you.

Wouldnt the civic Rev hard calibration be a better starting point than Greddy since my turbo is compariable in size more so than that of the Greddy turbo?

Upgrading my fuel system other than injectors isnt neccessary?
