I see posts around here, and some people say that they don't get enough HP out of their MB diesels. Maybe, they chose the wrong model. So, I have decided with some of my MB knowledge to start a post entitled, "Whats the right diesel for you?"
Ok, lets start off.
I think we need to look at the years 1949 to 1999, U.S. models only. The simplest MB diesels were manufactured until like 85 I guess, maybe 89? I have the chassis numbers, and HP on models that I know of.

We'll start off with the OM 636 engines
(W136) 1949-1955 170D/170SD 43HP
(W120)1953-59 180D
(W120)1959-61 180Db

OM 621 engines
(W121)1959-61 190Db
(W120)1961-62 180Dc
(W110)1962-65 190Dc 60HP
(W110)1966-67 200D 60HP

Now, here we go with the OM 615 engine
(W114/5)1968-73 220D 60HP

The OM 616
(W114/5, W123)1973-85 240D 67HP

OM 617
(W114/5, W123)1975-85 300D (DT too) 123HP
(W116,W126)1978-85 300SD 123HP

OM 601
(W201)1984-86 190D 72HP

OM 602
(W201)1987-89 190D 93HP, 123HP Turbo models
(W124)1990-93 300D 121 HP

OM 603
(W126)1986-87 300SDL 148HP
(W124)1987 300DT
(W124)1987 300TDT
(W126)1990-91 350SD, 350SDL 134HP
(W140)1992-93 300SD 148HP
(W140)1994-95 S350D 148HP

OM 606
(W124,W210)1995-99? E300D 134HP, 174 Turbo models

I hope you all enjoy this little bit of informative and/or entertaining reading. If you find anything wrong with this list, let me know.

I don't see the NA 617 listed. Also, I don't think the 617 was put into the 114 car for the US.

No US diesels '88-'89.

I would be happy with any Mercedes diesel. I am not a picky guy

Had a:
1973 220 (gas)
1980 300SD
1992 400E

I don't think the 90-91 350SD/L had 134hp.

Isn't there a 170D/SD/DS (W136 and W191) from the 50s?

87 300SDL

I don't think the 170SD was available in the U.S. I got the W114 and W115 confused, so that's fixed.. The NA 617 is in there, it's with the 75-85 300D. I'm not sure of the HP of the NA 617. If the HP of the 350SD/L is not 134, what is it then?

350SD/SDL

According to the book, it is 134 bhp @ 4K rpms and 229 lb/ft @ 2K rpm, with a redline of 4350.

But I don't believe in numbers. Take it to the track and see what she'll REALLY do.

I've had mine to redline in 4th at about 115 mph. It wanted to go faster, and it was pulling, but that IP governor....

Yes, the 170Ds was available in the US. It was a pushrod engine good for, IIRC, around 43 hp, with suicide doors in the front. They come up for sale quite regularly. I am not sure though, if they were sold on the showroom floor, or ordered individually for the customer.

It is my intention to own and drive one someday.
