I dont know about them. They kept changing the price on us when we had to rebuild a transmission. we agreed on like 800 something, and after verifying 3 times, we get there to drop it off and asked how much and they said 2700.... so yea....
plus, their turbo kits do not have intercoolers... they're very simple design and do not really give you as much power as they ought to. Plus, i seriously doubt that they have a turbo kit for the OBD2.
Good Luck. My first and only obvious reaction would be to point you towards Active autowerke if you are looking for a turbo kit for your bmw...
