okay so a buddy of mine has a 07 speed3. he just ordered a new turbo and said he would throw me his for free. that would be great and all but what would I need to make this possible? I know id need a downpipe for starters and fuel lines, injectors, etc. can someone PLEASE let me know everything I need to make this possible? I'd love to have a sleeper 3.
