EF9_808

Hi I'm new to the forum and this is my first post. I'm getting ready to do a mini me swap on my EF it has a D15 and has been multi point for over a year now. My question is scince there is a difference in displacement are there any issues as far a cam timing? Also I've pieced together a turbo kit centered around an IHI RHB5 from a probe Gt just wondering if it'll fall on its face at 7000rpm. Thanks for the help.
