hello,
i would like to find a big, black/green/blue/gray color 4 door mercedes.
turbo diesel.
not the newest models.
something economical and repairable without computer controls.

the best engine platform. good transmission.

i also like safety.

i want to possibly tune the car for medium performance.

what is THE VERY BEST model , engine, style, of mercedes for my purpose?

i want to find the best platform that will also result in good resale if i plan to sell.

what price am i looking at?
what mileage is acceptable?

any leads on what i am looking for?

i might also want to install a WASTE VEGETABLE OIL kit.
what kit is the BEST?

thanks!

hey there,
thanks for the reply.
i have seen that post. its rather confusing!
i understand by readint it that i probably do not wanna spend the money on the 99 models and the like.

why is the 1987 300d better than the later models like a 1992? or earlier models like a 1985?

i found a 1985 model turbo diesel 300 with ugly yellow tan color. it has 240000 miles. needs power window kit. turn signal. front sears. carpet. the a/c prb\obably doesnt work. for $1800.00
is that a buy?

it drives ok...front end is kinda shaky. not sure what it needs because it has been sitting a lot.

how much should i spend on the 1987 300d if i find one? any near atlanta or northeast ga?

can you bolt a manual tranny in a 1987 300d?

also, wouldnt it be nice to retrofit a gm automatic in a car that needed a transmission? i assume the mercedes automatics are SO expensive when they fail. scares me when looking at used mercedes!
but i love the chassis and engine!

any ideas?

ok you just opened a can-o-worms!

Yeah man, it confuses the hell out of me too because I am easily confused by the chassis numbers and engine numbers and then add the years! FML. haha

the '87 300 is special because it is the one year only inline 6 diesel 300. Dont ask me which engine that is!

The car you mention is worth about 1800 minus 1500 haha. sounds like it needs a front end rebuild, which isn't hard.... I just did mine.

I dunno how much the 87's are worth but if you can get your hands on one. do it.

Putting a turbo 350 or a 4l60e behind a 617 motor would be sweet!

hopefully some of the other guys here can give some input without the confusion...

The 123 chassis has the om617 engine which is by default very low in power. And up until the recent Injector pump tuning (see the thread on 7.5mm Floyd elements) it is very slow. So the engine platform for a fast turbo diesel has not been the 617 engine found in the w123. Most people choose the w124 chassis with the om603 (read lots about the engine before you get one). Dervtuning is a guy in MD who has developed the pump tuning with Tomniks sourced elements. The om603 3.0 liter was found in the 1987 300D and the 300TDT. They put it in some later models but don't bother with the 3.5 liter model as it had issues. I'll post more later, I'm on my phone right now and I need to get the steaks on the grill!

so a 1987 300d is the the ONE to get overall?

i have worked on heavy equipment most of my life. not automobiles. when it comes to cars, i worked on older stuff like classic musclecars. and work trucks.

i would really like a slick, tight black 300d mercedes turbodiesel. putting out enough power to keep up with modern cars of equal size. or at least out run a cop car! haha.

good mileage.
and safety.

i like to drive big work trucks for safety. i have seen so many deaths on the highway to reinforce my worry of safety. for some reason, i have come upon many dreadful situations on the highway and it has been gruesome.
but, the recent economic problems i have had...makes me try to compromise.
a big ole diesel mercedes. pretty safe u think? unless i hit a big truck head on......
i have found a few 1987 300d's for sale in my general area.

i dont understand the D part? i want the big mercedes body. they look tiny in the pictures. did the big version have the turbodiesel that is wanted?

what does D represent? is there different body sizes that arent explained by the D? is there a 450d in 1987? is that what i want?

also, the cars i see dont have the 1987 year only inline 6. they have inline 5 cylinders?

I wouldn't say that the 97 300D it's "the one to get"...it has the OM603 which is the 6 cylinder. It's the most powerful engine available without some form of computer control but many of them are plagued with head cracking issues.

The OM602 2.5L can be found in 300Ds from 90-93. It's the 5 cylinder brother of the 603. Expect about 20hp less but none of the head cracking problems associated with the 603.

The designation "D" simply means that it's a diesel...no such thing as a 450D either. If you're looking for a bigger car you could consider the 300sdl.

The Sdl is an "S Class" which is the larger car. The chassis is W126. That chassis ended in 1992 and the S Class then went to the W140 chassis. The W140 version of 6 cylinder 603 engine had a known issue of bending rods. So stay away! If you are wanting to give one more power, those bodies are too big anyhow.

The 300D is the E class, which is the smaller "economical" class. Then you have the C class which it the sportier/smaller vehicles. 1995 produced a w124 e300 with the om606 in it, but it was naturally aspirated and adding a turbo isn't recommended.

The big downfall with om603 is the #14 (original) head which, when overheated, was known to crack. Mercedes made several revisions to the head along the way. Many #14 head however have 3-400k miles on them just fine. Mines just shy of 200k. The biggest factor is making sure engine temps stay down by making sure cooling systemis 100%. I would say your ideal setup is a good condition 1987 300D with a newer head number installed.

how can i look and see if a car has the #17 head?

so the 1987 300d is a 6 cylinder inline turbo diesel that is modern looking compare to the year before it?

the 1987 300sdl is the same 6 cylinder turbo inline diesel engine with the longer wheelbase older looking body?

no difference except the body?

thanks so far guys.

Google w123 and w124. The 123 style ended in 85 where the new video style took over. 86-95 is the year the w124 chassis ran. There were minor improvements/differences along the way. Just read the wiki on each of those and it will answer a lot of questions!

Yuck. Those crude things are horrible. You're basically taking a 5-speed and removing 2nd gear. No different than shifting directly from 1st to third on the stock transmission, 3.68-1.44 on the 722, 3.06-1.63 on the 700R4. Plus, they can't handle any more torque than the factory 722 (290lb/ft). You'd gain an OD gear but at the expense of adding 4 seconds to your 0-60 and having to revv its nuts off in 1st all the time to get anywhere.

Youd be far better off adapting a 722.6 with a standalone controller.

awesome.
thanks guys.
this thread is getting interesting.

but is there an easy way to know if a 1987 300d has a #17 head?????????????????????
i found a few online for sale. i would like to be able to get the owner to look and tell me before i drive 200 miles to look at a car. what does a person look for?

ok. as far as the transmission.
it seems that one of the most critical cost prohibitive problems in used mercedes (and most used cars) is the tranmission right?
unless a car has a rod slung through the block!

it would be nice to buy a diesel mercedes(or any mercedes-gas-) with bad transmissions and know that you could BOLT IN a lesser expensive standard USA transmission like a GM or FORD. keep the nice car with its safe and tight body structure..and efficiency of the diesel engine(which they say runs 500,000 miles) and have WVO...but have the simplistic inexpensive transmission alternatives. even 5 and 6 speeds manual transmissions out of mustangs and camaros and corvettes for performance and mileage.

i am sure a person can adapt the diesel engine to ANY transmission and get a stand-alone computer controller for the late model overdrive USA transmission(buy adapters to put in toyota trucks and all...or get a machinist). but...is there a kit or way to BOLT the transmission in the mercedes car. know what i mean?

i found a few online for sale. i would like to be able to get the owner to look and tell me before i drive 200 miles to look at a car. what does a person look for?

ok. as far as the transmission.
it seems that one of the most critical cost prohibitive problems in used mercedes (and most used cars) is the tranmission right?
unless a car has a rod slung through the block!

it would be nice to buy a diesel mercedes(or any mercedes-gas-) with bad transmissions and know that you could BOLT IN a lesser expensive standard USA transmission like a GM or FORD. keep the nice car with its safe and tight body structure..and efficiency of the diesel engine(which they say runs 500,000 miles) and have WVO...but have the simplistic inexpensive transmission alternatives. even 5 and 6 speeds manual transmissions out of mustangs and camaros and corvettes for performance and mileage.

i am sure a person can adapt the diesel engine to ANY transmission and get a stand-alone computer controller for the late model overdrive USA transmission(buy adapters to put in toyota trucks and all...or get a machinist). but...is there a kit or way to BOLT the transmission in the mercedes car. know what i mean?

None of these cars are cheap, the W123 is built like a tank, the W201 is built for handling, the W124 is built for comfort. You pick which one you want. I would only go for a W126 really if you we're converting an SEC because its the sick coupe cruiser but they did offer a diesel four door model but it's a massive staff car though, but thats my personal preference. There is also the option of R129's which have a lot in common with W201's but no manual transmission and never came with a diesel. R107 is not my cup of tea. The only S-Class (excluding the W116 SD which the transmission and camshaft issues prevail) that came with a diesel was a rod-bender and only the head should be used off of that engine.

There are adapters out there to put a 700R4 on the back of the 617 engines

Yuck. Those crude things are horrible. You're basically taking a 5-speed and removing 2nd gear. No different than shifting directly from 1st to third on the stock transmission, 3.68-1.44 on the 722, 3.06-1.63 on the 700R4. Plus, they can't handle any more torque than the factory 722 (290lb/ft). You'd gain an OD gear but at the expense of adding 4 seconds to your 0-60 and having to revv its nuts off in 1st all the time to get anywhere.

Youd be far better off adapting a 722.6 with a standalone controller.

You may want to search it out. There is now a nice kit with starter & ring gear. Ready to bolt in a trans that can be had for peanuts & cheaply built to withstand anything a Mercedes diesel can put to it. The 700r4 can be pretty darn stout & anyone who can build a superturbodiesel should be able to build them with a book, kit & a couple funky tools.

As to the torque capacity of the 700R4, 290 ft.lbs is peanuts compared to what I have personally seen thrashed through one with 5:38 gears & 44" boggers with a heavily beefed big block. This was used at alot of mud bog events & just general showing off in the swamp. Cruised pretty good, too. Just had to keep a deathgrip on the wheel & turn up the stereo to dull the tire drone.

i did find this...

http://transmissionadapters.com/Mercedes%20diesel.htm

and this:

http://ecomodder.com/forum/showthread.ph...13000.html

but im not sure if it bolts in the car??

and, would this work in the 1987 300d inline 6 diesel mercedes?
and this post from this website:

http://www.superturbodiesel.com/std/gm-t...t-791.html

seems like the mercedes dash sits over the tranmission very far?

The first link you posted is for a weaker trans, but can be beefed to easily handle the HP & torque on a stock or turned up 617.
http://www.4x4labs.com/products/diesel-conversions/
is for GM manual transmissions & some of them can easily withstand anything that the most modded 617 can produce.
Both are pretty fine looking units to me.
4X4 labs I believe is working on a 700r4, or you might be able to have a custom converter built to use their adapter plate with the 700r4 & Mercedes flexplate.
Knowledge is power.

it seems that if a person could cross the expensive threshold of tranmission costs in these used cars...the economic feasibility would be justified. german parts=money.
according to most people..the engines seems to hold up. that is the main reason for the diesel mercedes.
and gas mileage.
night safe body and tight design.
but a bad transmission??? big money.
and then other issues i am sure like a/c systems etc...

if we could know that we could bolt in an american automatic transmission.
bolt in an aftermarket standard a/c system.
the rest of the car is what we want right?

except for cracked heads, blown engines!?

i assume the power window kits are inexpensive?
dash cracks can be fixed?
seats can be rebuilt.


so i am liking the 1987 300d and 1987300sd.
the inline 6 sounds appealing.
just as the inline cummins 6bt is in diesel trucks. i once almost had a cummins 6bt installed in a ford f350 truck but sold it before completion.

another thing i like is the idea of putting a diesel engine in a safe standard car like a crown victoria police car. cheap common parts. decent handling. room. safety. and diesel and WVO and good gas mileage! someone on youtube finally made this happen with the 4bt cummins.

http://www.youtube.com/watch?v=y7FT4z4U8Xw

i wonder if a diesel mercedes (non electronic) engine could be economically placed in a ford crown victoria police car? could the power be increased to rival the stock factory gas 4.6 engine? that would be a good economy commuter car.....
just bolt it up to the factory 4r70w transmission and have pre-made motor mounts. WVO kit in the large trunk.
wouldnt the mercedes diesel cars equal the weight of a ford crown vic? hmmmm....
the cummins seems to be TOO loud...

haha!

well. how much on average does the 1987 300d transmission cost to rebuild and replace? compared to a USA transmission?

also, is the a manual tranmission that can be bolted in the 1987 300d car? and foot pedal assembly?
