The 1993 300E 2.8 has 195 horsepower. To check the 300E models, or any other model for that year, go to
www.mbusa.com, and go to MODELS, and then click 14 year model overview. That should give you a bunch of information.
Also, head gasket failure was a problem for this year engine. And so was the wiring harness!
(pfphipps, actually the M104 motor started here in 1992 in the W140 300SE
