Hey guys i just bought a turbo from a show today from some guy... The only problem is i have no clue what kind it is or what it's good for... I know it has a fresh rebuild and it says Garrett on the side and air research on the other side... It also says T04 on one side and it says a/r 1.15 can anyone help me out please let me know if it's any good or a site i could possibly go to... Thanks for your help in advance
