It's an N/A 2 liter. Honestly, what were you expecting?
So I decided to be a little bit scientific about this torque business. As far as I know there are only two previous examples of Yamaha+D4s, the 2UR-GSE and the 2GR-FSE. The 2UR makes 373 ftlb from 5L (BMEP=184.4psi) and the the 2GR makes 278 ftlb from 3.5L (BMEP=196.4psi).
If we assume that the FB will end up in the same range of BMEP, we're looking at 150-160 ftlbs.
