TDI Turbo Upgrade: Passat 1.9, 86kW ATJ

Hello, I heard that the turbocharger from a 130hp Passat PD engine (engine code AVF and AWX) can be fitted to a 115hp engine (engine code ATJ). Is that true? They say only minor modifications are needed.
Does anyone know which one?
I think there are probably different turbocharger versions available for the ATJ engine. I have the turbocharger with part number 028145702h installed.

'The one with 130 hp uses a VNT17 turbocharger. The one you have installed is probably a VNT15. It will definitely work somehow. In my opinion, you'll need quite a few other parts for the intake system, and possibly a different oil line to the turbocharger.'

Make sure to check what type of turbocharger you have on the 115 hp engine, as it's possible that it's the same one used on the engines you mentioned.

AFAIK, the AJM and ATJ models have already received the VNT17 upgrade.

Okay, aside from that, what do you even need a loader that's 8 (or possibly more) sizes larger for? What other changes are you planning to make?
