turbo 4 cyl 3 series'

[threepi]

which 3 series models/years are turbocharged 4 cyl? I'm Very NOOB to bmws, recently totalled my infiniti fx and am considering gettting a 3 series but i've always wanted an FI car and have seen varying information regarding 2011+ 3 series and the 4 cyl turbo versions. any information or link would be greatly appreciated.

also, is there an aftermarket blowoff valve or wastegate that is made for these?

In sedan form its 12+, 12 being RWD only. The coupe did not switch over till '14.

Turbo bypass noises are Increased with An intake which there are few to choose. Injen is my favorite.
