ok so i was planing to rebiuld my engine pulled everything out and it was going fine until i opened it the rotor housings and rotor were scrated up bad...and i was wondering if u can swap a regular 13b housing and rotor into a turbo engine????

 

Yes for the housiong, but you'll need to remove the sleeve with the diffuser from the exhaust port and swap in a TII one. Or you could just grind it out I guess. The N/A rotors and TII rotors have different compression ratios, so you'll need to get another TI rotor.

 

I think you also have to drill out a coolant passage. Search and confirm that.
