please be more specific about what kind of car you have. Theres tons of different versions of the 3-series. Usually you should give the year and model (ie 325i, 318ti, 330Ci, etc...).

It will need some custom fabrication. First you can get some used turbos and rebuild them if they need this (cheap) Look at 80s cars such turbo crysler cars, mitsubishi, and others which have factory 1 or 2 stage turbos by Garrett which is one of the best around. Or can buy new once form them which are very similar, but better in performance. Then you will need aftermarket waste gates if the turbo doesnt have one, and you will somehow adapt the exhaust manifold for turbos (custom fabrication) and pipe it all. Also I assume that the engine is healthy or is already built up to accept boost. Then you get an intercoller and pipe it all together. You are gonna have to get some boost control devices after that, some custom prom, some msd ignition,some injectors and pump, gages, etc. It all depends on what your engine has and how much money you are gonna spend. Theres always room for anything (you can always install remote turbos) Look at 250 hp (you can take it to 500hp easily) Then you will have to beef up the tranny and the diff
