no, the only thing you will need are parts pertaining to the turbo, no serious engine mods are neede unless you plan on boostin over about 10-12psi daily. you do need the things you mentioned though, bigger injector to supply more fuel for all of the extra air the car is getting, for a daily driver you'll want an air to air intercooler, you will also need an afc to control the larger injectors, these are not engine mods, these are must for the turbo, unless you run about 5-7 psi., then you can use an fmu instead of bigger injectors and afc, it's very cheap, but you can't boost too hight with it. just to give you an idea, because it sounds like you don't want to spend too much money and have no idea what you're really looking at as far as what to do to your engine, all you need is all the parts for the turbo. i got all of mine for 800 bucks, turbo, manifold, bov, oil lines, 450cc injectors, afc, intercooler, piping.
