2.4s are nice and all but not worth it in my opinon....i have had everykind of 2,4 combanation in my car....n/a,,,nitrous,,,turbo,,,,turbo nitrous....it works well with nitrous but it dosnt rev as high as the 2.0 and its not as light as the 2.0..it dosnt matter what u use...u just need to know what kind of power u want to make and how much u can spend...
