2.5 turbo vs. 3.0 non turbo...thoughts?

A friend and I were debating the merits of a '93 300D 2.5 turbo versus a '95 300D non turbo, both 124 chassis. Any thoughts on which engine is more desirable? They must have changed it over for a reason.

OM606 is a robust motor for what it is. But that said, it's silly that they built a diesel engine without a turbo.

well, there were 2 OM606 at your GTG...


come down to mine on the 17th and take my '95 for a ride



I have yet to drive a 2.5

compared to my OM603, and my 240D 4speed, my E300 Diesel kinda feels like a turd, and you have no control over what it does...

I've owed a 92 300D (the ex wife has it now) and currently own two 95 e300's (one for me and one for my wife). Personally, I like the E300 because, in my opinion, it is a little easier to work on compared to the one with the turbo.

No control. Please explain

"Turd" compared to a 240D? Please explain.

Check the front control arms. The ones on the steering wheel.

LOL


I like the fact that with my 240D 4speed, I can easily control the RPM, traffic, lights, etc... and it does well despite the HP/torque (or the lack there of)

with the '87 300D, there's no need for a manual tranny (altho it would be nice) because it has power within 200 rpm of anywhere I cruise at... light tap with the right foot and off I go

with the '95 E300, it feels anemic compared to everything else (but don't get me wrong, I love the car as a whole) its just that, from a light... it feels like I'm towing a boat. 20+mph its fine until ball park of 50-60 then I find it once again struggles keeping up with swift moving rapidly changing traffic patterns... (not that my 240D doesn't have that issue... but again, i bring in the 4 speed opinion)

the '95 E300 is my choice of highway cruising, which is why I took it to your GTG (that and the E320CDI was in NY)

if I set the cruise @ 70+ (it really likes 72) it has no issues going up and down mild hills and maintaining speed, its just the 10% grades that I have it pretty well matted...

there's something about it that I'm unsure about... maybe if it was geared in a slightly different manner i'd be alright with it, but its nothing I'm so concerned about to go tearing things apart...

I am pleased with the performance of my 2.5. It is a good blend of power and economy. Plus, there is ample space to work in the engine compartment.

I agree with Oldwolf. I get 30MPG. And when you fully open the hood, Plenty of room.

Well the guy that owns a 2.5 turbo will tell you 2.5 is better and the guy that owns 3.0 non-turbo will tell you that his engine is better. My question is WHY MAKE A DIESEL WITHOUT TURBO? Yes if you have turbo there are more things to go wrong but why even buy a non-turbo charged DIESEL engine?

I suppose it is one less thing too worry about in terms of maintenance and replacement. Sometimes simpler is better.

Anyway, I would be happy with any diesel engine if it was reliable and economical.

We (the wife and I) get an honest 35 mpg in our 95 E300's which if I am not mistaken is better than the 2.5turbo.

I think their EPA ratings are higher, so you are probably right.

Isn't the 95 also more powerful? Seems like 121 V. 134 if memory serves me. This leads me to believe the 95s feel slower, but probably reach 60 mph sooner.

I've found a couple road tests of the 2.5 Turbo, back when they were new. Zero to 60 times are in the mid to high 10 seconds. Great video from Motor-Week on You-tube shows 10.7. Pretty impressive, I can hardly wait to get mine up and running. (Bear in mind my point of reference is the 617 Turbo.)

How does the 95 compare? I haven't looked lately, but I seem to have a vague recollection of 60 in 9.9. Feel free to correct and enlighten me if I'm wrong.
