What is Turbo?
A turbo forces air into the intake to supply the engine with air faster and therefore giving it more power and torque thru certain rpm ranges. they can be different sizes and these sizes will determine whether they work best at low or high rpm. the turbo has two turbines, one side if the turbo is connected into the exhaust side of the engine, and the exhaust gas exiting the engine spins the turbine which is attached to another turbine on the intake side. This is called forced induction. it provides a large performance increase.
