Just got my rx7 i knew when i got it that somthing was wrong with the turbos or there was a boost leak somewhere. Well i put my car on the lift last nite n found that my rear turbo was not fulling connected n leaking oil. I plan on going single turbo in the future but for now i would just like to get it running as factory as possible. Due to the car being shipped to the state in the future. What is the best way to go rebuild them or get a set of used one n put that on.
