Mirage will be more efficient and maybe more powerful as well. It has multiport injection and variable valve timing. If it's 2017 or newer, it also has cam rollers.
There's a guy who installed a Mirage drivetrain into a quad/ATV/dirt buggy...

hread: Not your typical G4 owner (3A92 engine & 5-speed swap into dunebuggy)
He used Megasquirt to run it, so that probably means no variable valve control, right?
