Putting a 3.3T in an SC is a very easy swap.
I used as many stock 930 parts as possible which makes things smooth. The 3.3L engine case is similar to the 3.0L so it bolts right up to the 915 using 915 clutch components. Main systems to be addressed are turbo oiling, fuel and electrical. I used all 930 oil and fuel system components. Wiring the pumps was easy as was the CIS which is similar for the 3.0L SC. The wiring harness plugged right in.
You do need to consider the weak points of the 915 and adjust accordingly (read no drag racing). Using a smooth turbo that does not hit hard will help.
