found the specs:
Turbocharged (max boost 6.5 PSI)
      SAE Net Horsepower............101 @ 3100 RPM
      SAE Net Torque (lb/ft)........175 @ 2200 RPM 
      MPG...........................City: 20 Hiway: 25

which means the OM617 has more HP, but less torque...

125hp @ 4350rpm 170 ftlbs @ 2400 rpm.
