Hi people i currently own a ford escort gti zetech 16v with k&n filter,was thinking about adding a 2.0l throttle body prob from a mondeo but will it just simply replace my old throttle body or will i have to do any mods and how much more power will it give,also what else can i do to get more power without a turbo conversion as i dont have much cash due to having 3 kids and a misses and only a £15000 a year paid job,thanks
