I'm looking for a cooling system diagram.
I specifically interested in the outlet port on the middle of the head under the intake manifold. I want to know how water gets there and where it goes.
I want to remove the factory retro-kit on the throttle body, however I don't want to dump hot water from the head straight back into the block.
I may run a Y or a T on the heater core from that port.

Why do you want to get rid of the TB heater? There are no noticeable gains from removing it. But if you do you want to hook the inlet to the outlet for the TB heater(With a rubber hose). I guess I don’t know much about hooking the inlet to the heater core but where’s the outlet pipe going to connect? Sounds like air in the cooling system. Just my $0.02.

The throttle body heater serves no purpose except to reduce cold start emissions and to heat air going into the engine bay. I don't see any reason to keep it if I'm going to be racing.
On the bottom right, the yellow line, it goes through 12-7-11, where does 11 hook up to?
The pink "?" hooks up to the purge soilnoid that connects to the charcoil canister.

17 goes to bottom of rubber boot #4.

top right corner of the upper intake manifold by the firewall

Where does the brake booster hook up to?
