Was wondering if those guys @ the shop knew that you are going to be turbocharged & will be running above 20+ psi of boost pressure & spinning it above 6000+ RPM's?
The rods are the weakest link in your new assembly. Hope they can stay together. Did you have the rods x-rayed, or some other for to check & see if they have cracks? Mag checked is not the best method to check for cracks. Cracks can be below the surface where a simple mag check will not see any defects.
