what you are thinking of is a "top swap" where everything from the heads up gets swapped to components from an sc 'ed car
heads ( with injector bosses )
lower intake ( no injector bosses unlike non sc engine)
m 90 supercharger
sc motor's throttle body
sc motor 2 belt crank pulley ( runs both accessory & sc belts)
all idler pulleys/tensioners that run on sc application
injectors & fuel rails from sc application
all brackets ,solenoids , vacuum lines ,etc...
pcm tuning for boost and gear ratio
sc wiring harness , or adaptor harness from zzp for conversion
misc.. gaskets, sealants, fasteners ,etc...
what this leaves you with is:
more hp than the sc motor on the stock pulley do to higher compression of the non sc pistons
weaker pistons due to no coating and thinner ring lands - they will survive fine as long as you keep out of kr (TUNE IS CRITICAL)
also the sc trans has a heavy duty differential which can be swapped but needs the hd diff cover also to complete the swap , many have run with stock diff - start using dr's & slicks better upgrade !!
I have sold many partial top swaps - I dont do harnesses, pcm tuning , or gaskets misc... etc.. but can package all the stock engine parts from an sc car for him for $600 shipped and can come up with an hd diff & cover for an extra $150
