Turbo questions
 

My question is this. What are all the parts included with a turbocharger system? I know how a turbocharger works, but I don't know what all the parts are or where they go. I know you got the turbocharger that boost air pressure, and the pipe that goes from the exhaust manifold to the turbocharger to run the turbines. Where is the Blow off valve, and how exactly is it hooked up. What other parts are in the system and how do they hook up? Any explaination or links to a web site are greatly appreciated. I'm serious concidering buying an 88 13B turbo for my 84 RX-7 and I want to know how the turbo works.

Oh, one more thing, what is the difference between Turbo, Twin Turbo, and TurboII? Twin turbo has a primary and secondary turbine right? Again, any help is appreciated.

Thanks
