Need more info on this mod

I am resurrecting this old thread because it has not been answered. I did this to a friends car today to prove it can be done. It is all bolt-in with no modifications except for stretching the brake lines. However, the results are very unsatisfactory. The booster came off a '78 300SD, and was rebuilt ($150). The car stopped fine before, so I know the rest of the brake system is good. My friend heard that the 116 booster in a 123 is an upgrade, so he brought the car and parts over for me to do it. The problem is, the car won't stop now! It takes much more pedal pressure than before to barely get the car to stop. I am wondering if the vacuum system needs to be upgraded as well. Does anyone know anyone that has successfully done this? I may have to put the stock booster back in the car so it can be driven......Rich
