I posted this in the NA engine forum and no one answered, hoping for better luck in the 5th gen forum:
I'm looking at using a 3.6 in a Factory Five 818. We know the 3.0 will bolt right in the 818 despite the 818 being designed around the EJ 2.5 255-257 series.
In looking at 3.6 parts I see the Tribeca 3.6 in all years uses the same side mounts as the 3.0 Legacy 4th Gen. But the 5th Gen Legacy with the 3.6 uses a new front mount and revised side mounts. I'm guessing the front mount and side mounts are new for safety/crash reasons and not performance?
Can I use the Tribeca 3.6/ Legacy 3.0 side mounts on ALL year 3.6 blocks?
Nothing like a race track to find the weak points in man and machine.
