W210 gearing. (Lower highway rpm) - Insane190d - 12-11-2019
Hello everyone just curious if there is a direct swap differential I could put in my 1999 e300td to lower my rpm at highway speeds. I've always felt like these cars could use another gear or two... did all of these cars have the same ratio? At almost 80mph it's a 3000rpm, it would be nice to see mid to lower 2000rpm. I also feel it would help spoil the turbo better having a bit more load.. Anyone? Also could I do a manual swap or is there too many electronics to get through for engine to run properly? Thanks

You can only do manual swap. If you swap diffs on automatic car EGS will go into limp mode. It looks after gear ratios.

The car has a stage 2 tune with egr and maf delete. T04E turbo. I put 1 size bigger tires on for winter and that lowered my rpm quite a bit!

AFAIK the E300 should have a 2.87 diff already, and it should be at around 2400rpm at 120km/h (74 mph). Maybe it's not shifting into 5th gear ??

Its shifting into 5th. Its probably around 2500rpm. Just seems like it could use another gear. What fuel economy do most get with these? I always seem to be 25 26mpg
