drivetrain and ecu. Unless the frs/brz trans can be mounted directly then really just ecu side of it. I haven't done much research but I wanted to do the same thing.

BRZ has higher compression and combines direct and port injection. I think there are more differences but the 2 I said are all I'm sure about.

Wow that car could only be 5 years old max, and it already spun a bearing? Dam...

The BRZ engine will not bolt up to the WRX bellhousing.

Also, check out Element Tuning for some great tech info on the motors.

IIRC quite a bit. heads and such are different, with the brz motor being the better one last i remember. but its been a couple years since I researched this so it could be different now.
