As you all know the 320i isn't a powerful car. I have already gone to driving schools and such. I have a Bilstein Suspension and i lowered my car 4". It's great to drive. But i want that extra kick in my car. So i was wondering if it is possible to take a turbo from another car such as a nissan,mitsubishi and saab and make a turbo kit for a bmw. I was wondering a ball park price of the mod. and maybe even the difficulty. Thanks :rock
