I purchased a1979 SC with its original 3.0L converted to a Turbo, PO added 930 P&C’s, fuel system, IC, ignition system and external oil coolers. Motor is out and completely disassembled. I want to keep the Turbo upgrade and need guidance on the internals. I measured out the crank it's in spec and is the original SC crank, rods are SC, heads are SC and had work done to the intake ports, engine block is 3.0L. Question: what can I do to strengthen the current crank and block to keep my great condition internals or do I have to upgrade to 930 internals? I don't plan to track the car or drive it everyday, I want to build a reliable turbo motor that's  not a ticking time bomb. 
 

 

Thanks appreciate any guidance.
