More air,more fuel,less exhaust always helps.

For the best ride use the stock sized tires and the lightest wheels you can get your hands on....probably the aluminum wheels off an 83 240d would be that. Bundts are the second choice.

I'm running the aluminum wheels with the wheel covers on my car with the Michelin Hydroedge 195/75r14 and bilstein shocks.

It rides like a sweetheart. It steers and stops nicely too.

SVO supposedly boosts NOx, lowers soot & CO. DPF's (diesel particulate filters) look interesting too.

For more air you would open up the ports, use a hi flow air filter or add a turbo. One way would be to find a 617 turbo in good shape and retrofit, double your power.

Id imagine heavier wheels would give a better ride quality. An object in motion does not want to change direction, and the greater the mass, the greater this affect. Therefore, the heavier wheels should move around less and force the tire and compressed air to absorb more of the road.

But a lighter suspension and wheels are more easily deflected over bumps. It's a benefit of reducing unsprung weight.
Many years ago, I experienced a definite ride improvment when I swapped out my 4-cylinder Ponton's worn-out iron front brake drums for aluminum ones off an early 6-cylinder Fintail.

Happy Motoring, Mark

Adjust your valves and change your fuel filters if you haven't already.

I agree with R Leo, I am quite happy with the power in my 83 240, (Myrtle), I have driven a few japanese 4cyl cars that were twice as slow as my 240. I have heard people tell stories about how their 240D is just painfully slow, and that if it were any slower, it would be going backwards in time. After I adjusted my valves, ran some power services diesel kleene through it, and changed all the filters. I was driving and thought " where the F$%^ are people getting that this thing is soooo dog slow? It gets with traffic just fine.
Sorry for the venting, but it is a 60s era diesel, and does exactly as it was designed to do, VERY well. Provide fuel efficient and ample power to carry you safely and reliably for anywhere from 300k miles to who knows.. maybe a million?

Question thanks sorry about the long paragraph i have a big problem sure can use help

the time now is 10:30 pm i am at the internet cafe typing this i got here from home on idle (hope i can get back up the hills) i was crawling and could only shift up to the 3rd, it takes 10 minutes to get to town from where i live, it took me one hour to get here what i am trying to say is, yesterday i removed the regulating shaft of the gas peddle and because it wouldn't press properly and the manual was showing me a left hand drive vehicle so i thought the previous owner might have bent it wrong and made it into a regulating lever of a left hand drive car where as mine is right (Australian car) now i cant remember what it was like to get that shape, i got here without the gas peddle.
please please can some one take a picture of the regulating lever for me so i can get it back in shape my car is a right hand drive 1975 240D W115 2nd version.

i took the arm to a welding place and changed the shape of it not being aware that my manual was showing me a left hand drive cars arm now its all ugly and messed i hope i have been clear (used punctuation i am usually in a hurry to get home so that's why i make so many errors) i hope you know what i am referring to you its the arm from the gas pedal that connects on to the spring and the regulating shaft, that shaft which goes near the brake unit has an arm to which the link from that arm connects on to the intake.

The arm i am referring to has a rubber bush on it and the rod that connects on to it has like a hook to fit that rubber bush that's the arm that got messed can someone please post some pictures of this arm at a few angles so i can get it remade according to the picture you send me
I'll take a look after school tomorrow and by the way i will have to read what you have sent at home please i am in real trouble

thanks jeremy

You fixed it until it was broke; you're screwed now.

Some of the stuff on W115s isn't available anymore. about all you can do is try to find a replacement part through a dealer or at a junkyard or, 'repair' it back like it was.
