In US the only high CR B20 was the B20Z with the plastic box on top of the low rise intake manifold.

Yeah, it's possible he has that and he's not divulging said info. He could technically remove the box and just fit a cap over the hole, it'd work, but he'd lose a bit of midrange due to the decreased volume.
