You have come to the right place.
The 10.4:1 compression is a ratio. The higher the first number, the higher the compression. High compression is not so good for turbocharged engines.
You need to swap the tranny with the new motor along with the ECU. The B16 is a good choice. That should give you around the same power if not more than a turbo D15 but with much more reliability and drivability.
Good luck.
