I was wondering how the plumbing for the secondary turbo on the 3rd gens is set up. Doesn't the first turbo's compressor feed the turbine on the secondary turbo? What happens after that? is the secondary turbo's turbine gases then sent out the exhaust or are they also used for building boost?

 

Hey buddy you got it all wrong. It's really not that complicated but I doubt anyone will sit there and explain it to you. Do some searches like on www.robrobinette.com

 

both turbos outlets feed the same inlet (the motor) one turbo does not push another, they are both fed by exhauset gases just by how much and when is controlled by the car.
