true, however, the S2000 engine is an F20C. (but yes, it does spin clockwise). you've seen a k-series engine put in backwards? do link me, because i don't believe i've ever heard of this.
used S2000 motors can be had for $8k-9k. if you are planning to mount the motor tranversly, you'll have to adapt a K-series transmission or a custom transmission to fit. the S2000 motor however is dimensionally smaller than B16A; in fact it is about the size of a SOHC D16. but getting a transmission that will work with it is the tough part. if you plan to mount it longitudinally, you'll have quite a bit of trouble making room for the transmission, driveshaft, rear differential, and halfshafts.
let me know if you do get around to doing this. it will be quite a feat putting in an FR motor into an FF chassis for street purposes.
