what the difference if any between the factory N/A and the factory turbo motors obviously the turbo and all it parts but are there different heads, injectors?

 

*injectors are different, but the NA injectors work best in the IDIT
*pistions, wrist pins, and rods are different. the wrist pin is larger in the IDIT, cause the rod and pistion to be different also.
*exhaust valves are inconel in the IDIT
