Post subject:  Turbo coolant lines

Still collecting parts to turbo my D150. I have questions about coolant hookups for my Toyota ct26. Some people use their heater hoses to tee off of. Can I use the top of my thermostat housing with an added port to supply coolant? And to add a port to my croosflow radiator to use for a return? Or am I looking at problems with this scenario?

You'll want the coolant supply to be upstream of the thermostat (possibly drilling and tapping the cylinder head). There's a significant pressure drop through the thermostat and tapping downstream of the thermostat will not get enough pressure to circulate the coolant.

Thank you mad scientist. How about the port where the temp sensor is?

Sure, it's functionally the same as the upper radiator hose port.
