140BHP for the S13 (9.0 or 9.5:1 compression, no VTC), and 160BHP for S14 (10:1 compression, and VTC).
The stock CA20E has about 100BHP, CA18ET is 125BHP, VG30E is 160BHP.
The power will be right along with the SE S12, only the SE will have a little more lower end torque (it's a V6, duh! ).
Otherwise, the SR20DE has a pretty awesome powerband, I was pretty happy with my S14 DE. Even more now that it's turbocharged, same low end, but a ton more high end.
