I have the wastegate lines sorted.
You can use either 1 or both the fittings on the gate (external) the top one mainly being for adding pressure to the spring to increase the psi the turbo will pump, or in an electronic boost setup where the controller will hold down the piston until it reaches the desired setting (called gain on blitz units). My trust gate does have 2 vacuum fittings on the bottom which is was you may be referring to though-I will only be using one.

I prefer running vacuum lines for external gates from the throttle side so that the efficiency and fluctuation in temps of the intercooler has no say on the overall boost pressure. I find that it holds boost alot steadier, and my mind is more at ease know that the pressure in the inlet is exactly what everything else is getting.

Cheers Golberg,
I knew had no idea about the water pipes, dont have to bother blocking them up anymore! I'm pulling most pressure lines from the 3 port 7/64" distributor that bolts along the plentinum (spelling?? haha) just need something a little bigger for the wategate and bov lines-all sorted now.
I'll call you today about the tail shaft.
