I am struggling with the coolant lines on my project. It's a 2.3 turbo coupe motor in a 1973 240z. The car has no heater core and I am using a Holset turbo that isn't water cooled. The original platform has a ton of coolant lines running everywhere and I'm having a hard time simplifying the system.
The lower intake manifold has 2 ports, I'm not sure what to do with these. Can I block one off and run the other into the return line? I also have a manual fan switch so I'm not using the port on the block for the coolant temp switch. However, there are two ports on the block itself... can I plug both up?
Does anybody have a water line diagram? I can't find any information on this.
I've included photos of how things are currently. The two hard lines are for the oil cooler.
