Now onto that all important turbo, there have been some big changes with this but still the same turbo GT1852V.

First of all I wittled down from two adaptor plates to one so it sits higher and is neater:




The next big change was to the manifold. I am running an external wastegate as well as the electronic vane control:
How the EGR port started:







I then used the second of the original adaptor plates to make a plate for the wastegate to sit on and the valve seat overlapped the manifold otherwise.






Next, I wanted to clock the turbo so that the oil drain was completely vertical. Not that straight forward with a VNT as you have to rotate the whole internal mechanism the same amount as you rotate the external part. This meant re drilling and lots of measuring...








Not so vertical


After the above work
