Junkyard Turbo
Junkyard heroes claim you can slap on a set of Thunderbird turbos and go to town. That may be true, but you will be giving up a lot in doing so. Aside from the improvements in bearing technology that add longevity and performance to the turbo, the compressor efficiency maps on newer compressors are much wider, allowing you to run more boost in a wider rpm range than the OE stuff. You can also get away with running a single turbo to achieve the same power levels.
Turbo Terms
Boost: Any pressure above atmosphere measured in the intake manifold.
Boost threshold: The lowest engine rpm where the turbo can produce usable boost.
Compressor map: A grid of numbers used as a tool to evaluate the efficiency of a turbo in relation to an engine.
Compressor surge: Air that backs up, causing the speed of the turbo to become unstable when the throttle is suddenly closed.
Lag: The delay between the change of throttle position and the production of usable boost.
Surge line: The line that follows the far left of the efficiency island on a compressor map where the turbo becomes unstable.
