A proper conversion will cost a LOT of $$$$...I spent roughly $22,000 converting a 1983 SC to a 3.3L turbo(1986 930 engine)IF you SC is in good shape, it may be worth it just to sell it outright, and buy a properly sorted 930.

The tranny is also something to 915 was beefed up, with a Proforce Clutch/Flywheel wet-up. The conversion was done by 911 Design(which also run a 911 in the ALMS series) in Montclair, CA.

Personally, i don't recommending trying to make a 911SC engine into a 930 engine. The 930 engine was designed from the get-go for forced induction...not so for the SC series. What you may have at the end of such a project is a 'bastard-child' which may be difficult at best to sell or establish a value(kinda like doing some home improvements which can actually de-value a home)

Contrary to popular belief, parts numbers on 911 engines that start with 930_... are not 930 turbo parts lifted onto the regular 911.

Good luck whatever you do!
