This is a joint MR2OC and LotusTalk meet, just as the thread states. I organized this event, along with my very good friend Kustom Play, an old school UBRF/TeaMR2 member.
And Toyota supplies the 2ZZ engine (former Celica GT-S, among others) for the Elise/Exige/2-Eleven. They have done so since the cars became federalized.
