kiwivolvo - most excellent conclusion.

It would be great in a week or so of driving you circle back and write up a recap. Summarize the differences in the two motors, what you moved over and what you kept and of course driving differences. It will be great info for future users.

Do you have the ECM and turbo from the donor car? If so take a picture of the labels from both ECMs and post them.

Maybe we can work out what it would take to get the 2.3 engine up to full T5 performance.
