have you had any problems with it???

MRNRL

I have only had the car for 6months. When I bought it it had 44600 miles on it. The prievious owner only put 22000 miles on it in 6 years. Now it has 55000. Only problem I have had (knock on wood) was a transmission leak. which just required the replacement of a couple of O-rings ($600). I currently have one issue with the seatbelt extender on the drivers side, the gear is stripped and I dont want to replace the entire motor ($638.00) for a plastic gear. I am waiting on a company that makes a replacement for this plactic gear for the W126 coupe but has not finished developing it for the W140.

This is my daily driver.

hehe, yes.

Whats the enginecode?
Engine weight?
Durability? (when tuned)

MRNRL

Engine code I believe is 120. I would need to check some documentation I have at home to be sure.

I have never seen the engine weight listed anywhere.

I was told that the engine alone new cost $42000.00. Dont know how accurate that is.

Durability? Have never found any long term testing of this engine or car. I would like to see that information also. Everyone I talk to says that the engine should last 300,000 miles easy. But where is the proof.

moa4r

how do you like the 420 lb ft of torque??:p :p

MRNRL

The torque is good but if I wanted it to be better I found that PowerChip makes an upgraded chip that will take the engine to 420 hp and 449 ft lb torque. The cost is $840.00.

moa4r

nice, i'd be careful with those mods btw, bcs you might need to make other changes so the engine/transmission can handle all that extra power...

MRNRL

I am not planning to make any mods like that to mine. I will save the $840.00 and put it toward my saving for an SLR

The air filter is about all I will do. Other than that I will keep it stock.

MB AMG

1992 600SEL has 402HP and 428lb-ft torque that uses the more durable 4 speed auto. Great power! I want a 7.3L AMG conversion!
