13BT Turbo Water Lines

Assuming one removes all the coolant lines up by the throttle body, what's the preferred method of blocking the coolant from reaching the intake manifold? (Or can I?) And if we do block all that off, what're the best locations to grab and return water for the turbo itself (60-1 HiFi)? Pictures are more than welcome.

Thanks!

in the stock configuration, the turbo water comes from the rear rotor housing, thru the intake manifold into a water pipe into the turbo. the other side goes basically thru a hose to the bottom hose barb in the water pump.

if you block off the holes in the rotor housings then you have no turbo water.

its in the shop manual, http://foxed.ca/foxed/index.php?page=rx7manual

the throttle body coolant has nothing to do with the turbo

Is there a good way to keep the water away from the intake manifold altogether? Thanks for the link, my FSM is somewhere with the car at the shop. Just want to simplify as much as possible while we figure out where the water [in the exhaust] is coming from...

I was wondering if there're alternatives for routing the coolant, especially with no heater core, and no real reason to run it through the intake manifold/throttle body.

We ran the water from the fitting in the back of the thermostat housing to the turbo. We used epoxy to seal off the two ports in the housings into the intake manifold. We also welded the coolant bungs for the heater and the one going up into the intake.

Thanks Trent! I forwarded that over to the shop; you wouldn't happen to have a picture of the water line routing hiding somewhere?

Sadly, no I don't have any pictures that show it well. Basically, I use the bung on the back of the water pump/thermostat housing for the supply line. I use the normal return line on the lower water pump for the return.
