Hello everyone, I am looking to supercharge or turbocharge my 1999 m113 sl500. I have ran into so many different scenarios of what to do. I currently have all the parts to turbo, or supercharge, the car. I have been given so much differing information that I have accumulated the following parts:
I have a turbo (exact specs I forget at the moment)
rear mount flange and wastegate.
oil pump, reservoir, scavenging pump.
intercooler and piping.
An m113k supercharger complete with intercooler, and surge tanks.
Stock m113k injectors, 550 and 635 injectors.
​​dual fuel pumps.
aem fic 8 piggy back
Heat exchanger, pump and water lines.
I probably have all the little odds and ends to wire/plumb 5 set ups in my parts bin.

I'm heavily leaning toward the supercharger. Vrp makes a solid pulley kit now for the conversion. I like keeping it "mercedes." If at all possible I'd like to use the factory ecu but that seems like a bad idea even with fixed pulleys/block offs.

I always get the best responses when I say explain to me like I was a child what to do. So to supercharge the SL should I try and get an m113k ecu and wiring harness or should I go another route. Those that can share some knowledge, please do so for this poor guy lol
