Allegedly, this Yaris sedan from Puerto Rico has a Celica GT-S 2ZZ-GE engine swap, making it a lot faster than a standard 1.5-liter Yaris. Want proof? Here's a video.
Yaris 2zz - 13.18@92mph vs Civic - 10.90@132mph
Although I haven't been able to find any photos of the actual engine in the bay, 13.18 seconds is about four seconds faster than a typical Yaris in the quarter mile.
