Turbo or Supercharger
Looking to do some engine upgrades to my '01 325i. Can anyone tell me whether a turbo or supercharger is the better option. Also, besides just slapping that on what else would i need to change in my engine? Is a new computer also required? And could anyone suggest a good place to order these things?
Sorry about the noob questions but i'm not a mechanic but def have an idea of what i wanna do, and want to learn. Thanks!!!
