turbo system opinions
This might be a little long sorry in advance.
I have a 2002 ZO6 with STS turbo kit and their are some weird things I'm not used to. The turbos are only on the springs no controller. They have hoses going all the way from the to the top of the intercooler to the back of the car to the bottom of the waste gates (tops open). I know on my last race car I had it from the compressor cover to the bottom of the gates and the top to the controller. I don't know why they run so far and should I just move them.
Also the PCV system has a boost switch and another switch that has three hoses on it. 1 goes to turbo air filter tube. 2 goes to the Right valve cover. 3 goes to the throttle body. I assume when the boost switch sees pressure it closes the other switch to not allow pressure into the engine(seams crazy). It also had a the original Valley cover to PCV valve with a check valve in it. I added a catch can and removed PCV valve but left the check valve to not let pressure in the engine.
I would like to get thoughts on removing the two switches and capping off the Throttle body and intake for original PCV. I would then run the valley and valve cover to the catch can with the air filter tube pulling air on the other side of the catch can. I don't need to worry any emissions testing.
Any thoughts are great
Thanks

Yes you could drill/tap the compressor covers for the wastegate boost reference but if the setup is working I don't know why you would want to change it.

The switch on bottom goes to the bottom of waste gates.
If you look at the PCV switch the hose on right goes to valve cover the hose on left bottom goes to the throttle body the one on left top goes to the air filter tube.
It just seams like a strange set up. My last car was a single turbo made over 1000hp and just ran two -12 fittings from the valley cover to a catch tank. I'm not sure if STS did this stuff for emissions or what.

On my setup I have his PCV can connected to a 10AN fitting on the pass. valve cover and the PCV fitting attached to the intake manifold just behind the throttle body. On the other side I have his draft can with a 10AN from the valve cover and another 10AN to my turbo’s intake for the clean side.

I’d ditch that PCV switch and run a mighty mouse pcv can. Mighty mouse includes a diagram of how to set it up correctly on these motors.
