dont mean to be a douche but cumon people just search. if you even have to asks these questions, you are nowhere near informed enough to begin this project. this is just getting annoying

forget him...turbos can be expensive...depending on what you want it would cost around 2500-4500. and i would sugest taking it to a professional to install it..i heard they are quite tricky

it would prob be the same..id say buy an entire kit kuz you that way you will know what you are getting and that it will work

without extensive knowledge of these systems, expect to pay about $6000 for a well put together, installed and tuned system.
