It is possible and easier than turbo.
You don't need oil feeds for most chargers
If you go low ish boost you won't need an intercooler or decomp plates/pistons etc
You will need a remap/new ecu
I wouldnt say its easier.
oil pipes are nothing. the feed pipe is an off the shelf part that can be made up for about £15 from any place that sells hydraulic hoses
the sump just needs a drain welded in. which is just a 1inch bore tube
Imho a SC would be a lot harder as you might need to look into the crank pulley (not the crank itself as people keep saying)
then you have pulley ratios and belts.
the pipe work from charger/intercooler/tb would be more complicated then a turbo as its all close together.
Be interesting to see a supercharger on a small displacement engine.
you would never make the power of a turbo
turbos basically make use of waste energy while SCs use power working power... IIRC i remember reading that use a quite large percentage
hence why a lot of proper production SCs disconnect depending on load/rpm
Id say for what its worth and what you would get from a sc it would be easier to fit a small turbo with a huge waste gate.
you would get very low lag (my GT15 turbo had no noticeable lag but killed the engine at high rpms because the small wastegate) and free exhaust flowing at high rpms.
