5-cylinder turbo bolt-on question

[derek]

For those who have installed watercooled turbo parts onto 5-cylinder motors
not originally equipped, where did you route the lower turbo water line to?
Is there some trick to pulling out the freeze plug without removing the
manifolds or head?  Did you find water somewhere else, like those two plugs
on the back of the head?  One of the heater core pipes?

Stupidly I left this step for last while converting a JT motor with KH turbo
parts and wiring.  Everything is installed, the motor started today (sounds
great with just the downpipe!), but I can't add coolant and test drive until
this is resolved.  Grr.

Any ideas would be appreciated.  Thanks in advance.
