So, it's been a while but I've eventually got around to giving this a go.
Couldn't get to the rear cartridge retaining bolts so I just too the turbo completely off to slacken them. Bolted the turbo back on with the exhaust horns removed so I could see what was going on.
This is how the outlet pipe addresses the block with the turbo cartridge in it's original position.

You can see that it is misaligned with the fitting on the block.
I rotated the cartridge to get the pipe in to this position. However, it doesn't help with the misalignment.

So it get's closer to the block, but doesn't help because of the misalignment.
When I push the pipe across to get it in to the fitting it obviously bends the pipe.

You can see the misalignment by how the union is lying in the fitting. The pipe is slightly bent in this position, but the more I tighten the nut, the more it pulls the union square in to the fitting and so the more it bends the pipe.
The reason why it's so oily around there is because I can't tighten that fitting up properly because of the severity of the kink it causes, so I have to do a half way house which allows it to weep.
The outlet pipe only bolts on the turbo one way. 180 degrees the other way and it would be facing the inner wing, so I can't be fitting it the wrong way.
The only solution I can think of is a custom made pipe.
Any other ideas welcomed. Or thoughts as to what I might be doing wrong.
