Just bought a gt35r and im confused where to run the lines. I saw that b&r makes a kit but im looking to do the other off the tb or something. My problem is that im using a blox 72mm and it doesnt use a coolant line to the tb. So do i use the hose that would go to the throttle body as the feed? Now what hose do i T to use as the return?

 

Parallel:
'T' from the inlet to the heater core to the inlet of the turbo.
Outlet of the turbo to a 'T' on the outlet of the heater core.

Series:
Run the line that normally goes to inlet of heater core to inlet of turbo.
Outlet of turbo then goes to the inlet of the heater core.
- you can also do this at the throttle body
