Outrun 2 runs on the "Chihiro" hardware
...so it isn't a Naomi hadrware based game. They MAY have done one in the universal cabinet, but i have never seen any information on one and you would really want to have it in a sit down cabinet anyway. Many of the Sega upright racers (like Daytona and Sega Rally) don't have force feedback. I have a Sega Rally upright in my collection, and although fun, is just not as much fun as playing it on a sit down cabinet.
I have an Outrun 2 twin that i have converted into a "SP" special stages model, which doubles the number of courses, cars and music. I am only aware of five different Outrun 2 cabinets. The original red twin (which has a common header), the original red single (which has a built in marquee above the screen), the original Outrun2 deluxe motion cabinet, the (different) yellow cabinet for the dedicated "SP" special stages version (which can be used as a single or linked with multiples without a common header, as the marquee is part of the single cabinet), and finally the super insane deluxe SP model which features replicas of four of the cars with seating for two in each of the linkable deluxe units. You can find pics of this online, and the only one that i have ever seen in person was at the Gameworks in Las Vegas...
