Hi,
I really love this board and so I would like to share some details about my car:
The E420 I own was ordered in Germany by a lawyer in 1994. Altough leather is standard, the car was ordered with the normal black fabric seats of that W124 area. For driving with a suit, this may have been a good choice in summer and in winter.
After some years the lawyer gave to car to his brother who drove it some more years. With 424.000 kms on it (ca. 265.000 mls, driver's seat undamaged (!)), the car was given away to a friend with a workshop with the only option not to sell the car but to scarp it and sell it in parts. The owner kept the car-papers. Of course (a friend...), the car was sold as a whole. The buyer was selling cars and wanted it for himself. At that time, a friend of mine, knowing every Mercedes in our area, became aware of the car. He asked several times to buy the car but did not succeed (he did not want to pay that much either). But he still kept an eye on the car.
When atempting to ask again, he was told by the wife of the owner that the car was going to be sold that afternoon and that the buyer was on his way.
He was upset and waited for the buyer. When the buyer arrived, my friend told him that he cannot buy the car and that the car was already sold to him instead. The buyer left and the very upset owner discussed with my friend. I dont want to comment on this, but as a result, the car was sold to my friend.
I shared a garage with him at that time and the E420 now stood in a part of that garage for two years. My friend was not able to get papers for the car, which is in a way related to german legal procedures with cars lacking the papers.
I asekd him to sell the car to me and after a while, he did.
In order to optain the car's papers or a legal document in order to have new papers issued, I drove (prepared with the necessary documents) to the owner who was the last one to have the papers (the brother of the lawyer). I arrived there on a Tuesday after work, in the countryside, cold and rainy in October, and rang his doorbell (I only had the address). He was not amused and let me stand in the rain for half an hour arguing about the papers. It apeared that he had destroyed them because he was afraid of warrany-issues with when selling the old car. I left all my arguments and preparated documents and after a week, to my surprise, I received the papers which were necessary to get new papers for the car.
I welded a lot, but mecanically there were no issues. The car is not a beauty and it is meant for driving. I am trying to keep everything original, but since the value is low, things can be tried out.

Cheers
Nic

A very interesting story indeed! It's encouraging to hear from people who go to great lengths to keep and enjoy these W124 cars.
I've spent some time myself hunting previous owners of various cars through the years, searching for information. I even had someone contact me some 20 yrs. later asking about one of my previous cars.

Hello Nic,
great to see your car still on the road after that story and that miles! Looks like the first owner exactly knew what options he wanted to spend money on.
And great to see you taking good care of it!
Thank you very much for your PM! I would like to answer it, but can´t answer you or send you a new PM (probably because of your account Settings not allowing incoming PMs).
 
Tryed to demount the front one-piece flywheel yesterday. Did not succeed, because the mount of the visco has to be detached - I didn‘t have the time to do that.
Learnings:
- The left exhaust pipe has to be demounted to access the left locking position on the tranny. No way without (but no need to demount the starter on the right side.
- the locking tool is available from other providers in good quality. 69 € incl shipping in Germany.
- the visco and the radiator should be demounted. Not a quick work.

260kph = 161mph, nice!

What rear axle ratio, and what size tires?

I assume it was the engine RPM rev limiter?
 
Hi,
rear axle is 2,65, tires are 225/45 R17. It is not hitting the rev limiter, must be the restriction from the LH.

Hmmm. Is the EPROM original/stock? I have a chip that will remove the vMax limiter.

:jono:

It is stock from a S500 W140. Since I only have this one module with WOT enrichment, changing the eprom would be a task for a second LH module.
Does your chip have wot enrichment?
 
That’s FAST, my friend! Well done and cool to see the ultimate sleeper w124 in action. Would love to see a few videos where you show pulling power, e.g. from 80 km/h to 200 km/h and from 160 km/h to 250 km/h...or in your case 269 km/h 😄 .

Consider me greatly impressed by what you built! 👀👀👀👀 Very, VERY cool!!! 👍🏽👍🏽👍🏽👍🏽

Hi Tim,
thank you! The car is now running with Dave‘s eprom and he also was a big help with knowledge. The support from this board is great!


This is 100 to 200 km/h, but it was too crowded and short for anything faster.

I read my initial introduction again and noticed I have not mentioned that I have put an E50 AMG engine from the W210 into the car. M119 with 5 litres, ported heads, 11:1 compression and AMG cams.
Running on standard LH and EZL from E500 W124. Standard transmission.
There is a E50 conversion thread about that.
 
Nic,
what a machine, very impressing! :love:
Now put a "Wackeldackel" in the back and stick a "E200" badge on the trunk for the extra understatement and confusion!

If you mind some questions:
Is the E50 engine entered in the papers yet ;)
What suspension is in your 420? It looks lower than stock but seems to drive quite smooth.
Where did you find that engine? Looks like good E50 parts are a rare find.
 
Hi,
it is streetlegal with TUV for engine, cats, exhaust and rims. suspension is standard, 17 inch rims.
E50 engine was bought via ebay. it was a risk about the condition, but turned out good and affordable.

Aaah, to see that pulling power anywhere above 180 km/h is just sooo cool! Thank you for posting this!

I miss living in Germany and having access to the Autobahn.....that is truly the place where w124s with an M119 engine shine.....U.S. highways are just such a sad place for these cars 😫

And yes, :gsxr:

Trust him to have provided you with the right eprom to make your car's mods work :bowdown:

Nice pics! Who makes that front catalyst pipe shown at 2:06? Looks like Fox cat-back? I think you posted this info elsewhere but my memory is foggy...

Hi,
did one lap on the Nordschleife yesterday and I am very concerned about the brakes now. (It‘s not good fore the tires as well).
It was my third lap on NOS overall and the first one with the W124 with the E50 engine. Temp was 26 degree Celsius, fueltank was full and all normal stuff on board (spare etc).
I drove faster then the last time and used all of the engine power whenever possible. I probably breaked too much due to an amateurish flow with s lot of edges.
After one lap the brakes were gone completely upon leaving the circuit. I had to push the pedal several times before some stopping power would appear. Brake fluid was about new, so are discs and pads and hoses. It took about 20 min on the road to get the brakes working properly again.
Next time, I have to brake less or change something on the system.
Coolant temp was more a concern before but that was not a problem.
Nic
 
The cars are too heavy for the track (but of course fun on the straight lines). I would like to go on the nordschleife this summer but either with the E63 or C36.
 
Nic, that tire photo is awesome. I've only done that on my old GSX-R750, years ago when my bones were more rubbery.

What size brakes are on your car, what pads are you using, and what brake fluid did you have?

Castrol SRF (or something similar) should help a little, but if the pads can't handle the temperatures, better fluid will just prevent boiling. Chart below from my brake spreadsheet, sorted in order of WET boil point. Motul RBF600 or RBF660 might be decent alternatives to SRF at lower price. Remember that SRF needs more frequent replacement.

Hi Dave,
thank you for the info on the brakefluids. I had considered the Motul 660, but it is not that much cheaper and I have read different things about the frequency of changing SRF.
I am using the latest 420 brakes (320 front) and ATE pads/disks.
The brake was very very hot, I think the fluid boiled in the front calippers.
I will add something for airflow as well, but no other brake update is planned. The NOS is not my frequent habitat, that‘s too much wear in not so
much time. But I want to be a little better prepared for the next time.
Nic
 
If the pedal was very soft, or had abnormally long travel, you may have experienced boiling fluid. If the travel was more or less normal but the brakes just wouldn't stop the car, that was probably the pads overheating. @jhodg5ck would be able to tell you what to look for.

I think 320mm front and 300mm rear is the largest you can get through TUV without hassles, correct? Is there any way to get the Silver Arrow front calipers TUV approved?

The ATE pads are your next limiting factor. I would consider Porterfield R4 (race compound) pads for Nordschleife use, but they are expensive. Maybe EBC Yellows might be worth a try if those are easier to source. I'm not sure what other track-ready pads you can get for the 320mm fronts. EBC doesn't offer their race-only Bluestuff in the #561 format (294-320mm Ate fronts).

:3gears:
 
Hi,
thanks for the advice on brake pads (Pagid RS/EBC Yellowstuff). I found the Yellowstuff pads and will give them a try.
The pedal went all the way to the floor on the final meters, the brakepower itself was ok all the time.
After reading around a bit, this seems to be not such an uncommon problem on the ring for braking-amateurs like myself...

My prototype venting flap, plastic, have to decide how to protect the strap-ties to the sway bar from failing by wear/movement. I tried this on my other w124 because it was available at this moment.
What do you think? Will this help cooling?
Nic
 
Great idea! Just make sure the flap cannot rotate on the bar, at high speed when air pressure is increased.

:3gears:
 
Just tried at 200 km/h, no issue. It can also, because it is not flat and has this preshaped 90 degree bow in it (ex 20 liters mobil 1 can).

The summer version of the front cover. The wiper is not supported by the cover, so there is no use in leaving in that area. The water-lines can also be connected without the link in the cover.

edit: after 4 hours and looking at the poor car, the possible advantage does not matter: it looks ugly to me and will be changed back to normal.

Awesome! Any difference with the brake cooling ducts? Same brake fluid / pads, or did you change them?

:choochoo:
 
Hi, Dave, Brakes with ducts and Castrol SRF. No issue this time, did two laps with a short cooling turn up to Nürburg village. disc temp right after first lap 230 degree celsius, Calipper 120. ATE brake pads (EBC yellowstuff will arrive tomorrow).
It‘s not a race car, but it still was a lot of fun. All other cars with cage and helmets today...
 
Nice video!

BTW, the biker at 1:50 could have easily made that turn. I'm not sure why he stood the bike up and headed for the gravel. At least he kept it shiny side up!

:scoot2:
