Mercedes-Benz W124 - Differential - The Hillbilly Hammer

Nothing technical just my personal viewpoint on how critical gearing it is in getting the most from the horsepower you already have. I would like to see someone convert one of these cars directly to a Speeduino fuel injection setup with this 3.69 rear gear just to see what the sum of all these parts truly equates to. Just do away with the problematic LH/ASR setup. The ignition is already independent as well as the transmission. One could install the rear gear and fuel injection for no more than $1000 and have no limitations. Sorry I said 117 engine and we all know the 400E is an M119.
