Has anyone installed their coolant fed turbo this way ? Is this the best way to tap into the lines?

Is this a constant flow source, I'm a little bit unsure as it goes into the heater core, and when the heater is off, will the flow still be present through these lines?

 

One line feeds the heater core, the other is the return. When the HEATER is turned off there is NO FLOW through the heater core. It's controlled by a solenoid inside the dash that will open/close that line from 0-100% depending on a bunch of factors like inside and outside ambient temp, target temp on the AC controller, etc.

All the VQ twin setups I've seen tapped into the oil cooler coolant lines to cool the turbos. Normally you are deleting the factory oil cooler and going with an aftermarket one that's not a coolant liquid to oil liquid cooler (they just get coupling together when you delete them to use a real oil cooler) so you just repurpose them for the turbo cooling instead.

 

which lines are these do you have a picture?

 

also are you sure it closes flow through those lines? Some cars let the coolant flow through the heater core 100% of the time. I am unsure if the g35 are that.

there is no part number for a coolant control valve... so i would assume they flow 100% of the time on our cars.

 

Maybe it does? I've never taken it apart. I bet you could watch Speedkar's video where he chopped one apart and find out if there is a valve inside it somewhere.
