Depends if your technical minded or not..can always read the how-too section but thats boring! asking direction questions is the way to go!
also depends what tools you got.. if u wanna do stuff at home, try the front mount intercooler first see how your liking to getting your hands dirty, or splitfires..
Injectors, AFM, Ecu+tuning and zorst.. should be done at a proper workshop.. incase ur not too confident with the whole things...l
