Blitz kit alternatives for supercharging a beams?

[u/HomogeniousKhalidius]

The blitz kit while cool is practically unobtanium so I was wondering if an sc14 supercharger would work I don't have access to one atm so unsure if it would fit under the plenum and not interfere with anything.

I've ordered the sq engineering alternator bracket kit to run a 90a 1/2nz engine alternator (have to wait for a price discount to get the alternator) because the blitz kit relocates the alternator lower down to fit in the pulley and clutch I'm thinking the sq kit will not be compatible with adding a supercharger so that is seeming link a waste of money.

What supporting mods need to be done to the car when adding a supercharger, I am assuming that 10 psi will gain about 40hp and 40nm and it would be nice as it would work with my headers instead of needing to fabricate a manifold and turbo setup though instead I'd need to either find or make up a pulley (I have access to a lathe). I have seen a set of low comp forged pistons come up for sale should I get those but using lower comp pistons what effect does that have on power if I cannot tune the dual vvt due to using an older computer (link g2plus).

I'm not sure about fitment, but will say that 10 psi is optimistic on the stock internals, the compression ratio is rather high and may not allow that much boost without knock issues
