The stock M103-12V will do 0-60 in about 7.5 - 8 seconds.
That's from experience long before videos existed when I bought my 300CE new in May of 1988.
Most bang for the buck on the M103-12V is to twin turbo in the style of Mosselman or Turbotechnics.
Other then pressurizing the engine there are no real performance bolt ons that impact significantly.
Opening the engine up and building a 3.6 AMG style motor will give you ample street performance.
Either way you're spending about $100+ per horsepower. !
