Now that I am reasonably sure my Chinese reman turbo is the source of my low boost, I am strongly considering an upgrade to the VNT-17. Along with an increase in performance, I understand that the VNT-17 is perhaps more durable than the stock Borg-Warner unit. I have some questions for those who understand what is involved in this upgrade, or have done it themselves:
Other than the EGR cooler tube, does this bolt straight up?
Can I use my current exhaust manifold and swap the turbos themselves?
Is it necessary to swap larger injectors at the same time the turbo is installed?
Is it necessary to chip or re-tune the ECM at the same time?
If the VNT-17 is the stock turbo for the European TDI's, I might assume that the swap is quite easy and that the required parts can all be had from O.E. sources. I would like to keep things as "stock" as possible, even while upgrading performance and reliability.
