So please explain the port you are referring to on the front iron of the 13b.  Is it the one right next to the CAS (crank angle sensor)  if so it would appear that mine has some kind of plug that would have been factory installed. 

Attached is a picture, that also happens to show the ports I created for water flow to and from the oil/water exchanger.  

I'm still trying to remember what this oil outlet was originally for.  It was probably oil to the turbo, so I'm not sure if it's on the NA housings.  

There is also a port in the rear iron, the one nearest the flex-plate that I tapped with a 1/8 npt if I remember correctly and plugged it.  Is it possible to use this port, or is it to small for a supply line to the re-drive?

You might have to show a picture of the port to make sure we're talking about the same one.  There are water and oil holes in the rear iron.  1/8" NPT may be big enough, because the inlet to the redrive has a restrictor in it anyway.  I'd leave that as a Tracy question though.
