1+2 = Cold water feed to the turbos.
3&4 = Water return from turbos (heated water).


remember; JZ's have Cold water in low on the waterpump, and Hot water out on top by the timing cover.

Its actually the other way around. The steel pipe that is down low is suction from the waterpump, so water is fed from the upperneck to the turbos, then returned to the pump via the lower tube. That tube also provides the suction for the heatercore, oil cooler and iac motor.

Damn
I stand corrected!
Flow is actually reversed.
