Just completed the upgrade. Finally put in the GTB2260VK Turbo from the 3.0 TDI 059145722R in my 2,7 TDI which has the GTB1756VK 059145721F. From the VAG EKTA data it looked like everything would fit if the Y exhaust collector 059131799L was also replaced with the 3.0 Y collector 059131799R. This Garrett 059131799R Turbo the has the matching DP flange. However the EGR flange turned out to be a bit bigger on the Y collector which meant I ended up doing a 5mm thick block off plate. Also did a small flux wire weld to add a small holder for the turbo oil return line, which was avail. on the old collector.
Overall not a bad job to do, except access to the collector is a bit tight. Removal of just the turbo itself only takes minutes. Once I removed the fresh air intake piping/air filter and the charge air outlet piping on the pass side and the coolant reservoir on the driver side access was much better. The lower driver side bolt on the collector had to be accessed from below. The M10 bit is your friend. Had 3 different versions of M10 in play 1/4 drive 3/8 drive and single bit. managed to lose the single bit on the driver side.
Did a log with the same old tune and despite it being a bigger wheel the lag is less (see chart)! The EGR block off at the collector must have helped I take it.
The 2260 feels solid. Just need a tune now.
