Time to decide how much fab work you are willing to do for this project.

If minimal fab work is one of the build parameters then stock 930 equipment is a must. You can source a complete 930 CIS system for ~$1000, a complete 930 exhaust system including 3LDZ for ~$500 and all the do-dadds to adapt the fuel, oil and electrical systems for another ~$500.
So you are looking at $2000 in used parts. This is the most economic and simple way to go in my opinion.

If you wish to do some fab work and engineering I would still use the 930 exhaust system and adapt the SC CIS for turbo use. Find someone who has done this exact conversion or you will waste a lot of money and time figuring it out.

Hidden costs will kill you on a conversion. The further you venture from stock the more hidden costs you will encounter. Best to find someone who has done exactly what you wish to do and see what the true costs were and the true efforts/pitfalls.
