Physically? Sure... just like the 350 supercharger kits fit the 250.
In neither case does it add enough power to be worth the sticker price of the kit/install/etc though compared to just getting a faster IS... this is more pronounced in the 250 since the price jump for >100hp to a 350 is smaller than the price jump for >100hp to an IS-F is... but generally speaking supercharging a 2IS seems to run "around" $1000 per hp not counting labor (unless you cobble together a used kit or something) with the top end being +50-70 hp... if you wanna push into that 70 range you're probably looking at needing to make an F-con or MAPECU3 work, which tacks some more costs on though... so 350->IS-F starts looking pretty reasonable in comparison give you add another 30+ hp and get a better transmission (and presumably some warranty)
