I am considering either super charging or putting a turbo kit on my 2005 330ci zhp. I have been doing some searching and have some kits in mind. Does anyone know if an east coast installer. I couldn't do the install myself, and would like an experienced shop to perform the install. Have any Pros vs Cons of S/C to Turbo? I would like to talk to one of the guys at ESS, seems like their TS1 for zhp's is priced ok. Feel free to comment, I will have around 7k to spend.
