Adding a supercharger
Would an m113k supercharger fit on an m113 engine? I was recommended that an m113k swap was ideal but with my current budget would slapping on the supercharger itself work?

1. The M113k cars are speed-density and use a MAP sensor but no MAF sensor. You will need to convert to a M113k ECU and engine harness
2. The NA M113 engines have significantly higher compression ratios, so putting an OEM supercharger on it that was designed for lower compression may cause cylinder pressure issues. Make sure you don't run too small a pulley.
There are probably other things; those two are the first to popped into my head.
You might also consider running a Procharger or Vortec centrifugal unit. If your car is a W208 there is plenty of room on the passenger side to mount one, and you can keep the MAF sensor and stock ECU.

Yes, the supercharger from the M113k will bolt on to a NA M113 motor, but there are several things to be aware of:
1. The M113k cars are speed-density and use a MAP sensor but no MAF sensor. You will need to convert to a M113k ECU and engine harness
2. The NA M113 engines have significantly higher compression ratios, so putting an OEM supercharger on it that was designed for lower compression may cause cylinder pressure issues. Make sure you don't run too small a pulley.

to add my $0.02 you would need to heavily modify the exhaust and would possibly benefit greatly from converting to the 171 or 203 AMG rotors i wouldn't like to have 500bhp on the stock w208 rotors they aren't exactly the best standard brakes.
taken all into account your best bet would be to get a wrecked m113k car and swap over the hubs, rotor engine and harness but i know this is easier said than done.
