Im going to be buying a turbo legacy soon and need some help on parts and performance before I do any work on it. Like what are IHI turbos and what dose rotating a turbo do. What's dose the waste gate on a turbo do and why should do people put bigger ones on. Where is the best place to put a bov. What's the difference between recirculeting and non recirculeting bov. What do boost solinods do and can you put bigger ones on or swap them from another vehical. What are some on the saporting mods you need before upgrading the turbo. What is boost creep or boost spike. Sorry if im asking a lot but its my first turbo car and I wanna build it right.
