If you would to take the supercharger route, I recommend engine health check prior to that especially if it has a
high mileage. I strongly recommend to consider
lower cambelt protection cover (Pure Motorsports) in case crank pulley fails, it won't get stuck in the cambelt and jump the cam timing! (we had a case here). Last, for peace of mine consider
forge engine build to begin with. such force induction will stress stock engine so bad especially going all out!
Cooling element as
@PITA stated is very essential for such builds. I took Meg Conversion route for my Clio where custom shrouds (deleting AC) enhanced heat management so drastically (15-20 degrees C). That encouraged me to apply similar custom shrouds to my Megane 2RS as well where i retained AC and shift the Intercooler, and AC condenser mounts just to improved air flow into the radiator, and almost similar heat range drop was achieved
