M104.98x Motor Swap in a 190E

One of the most common engine swaps for a 190E is the installation of the bigger M103 3.0L motor. The swap from the smaller 2.6L M103 to a 3.0L M103 is a direct bolt-on swap (assuming the engines from the same cutoff years are used) and gives a small increase of around 30HP. Another option is to swap in the CIS version of the M104 engine found on the earliest M104 powered cars (1990-1992 300CE and 1990-1993 300SL). The injection system is still CIS and the ignition system is still EZL, but additional work is required to make the swap complete.
