B16B TYPE R ENGINE FOR SALE NO FURTHER A MYSTERY

I bought my MRS 3sgte back in 2020. Parker from NW Motor s identified as me and instructed me I had been obtaining a just one-of-a-variety, clean up 3sgte motor. and he didn’t lie. I’ve bought the pictures to establish it in advance of set up. I have not noticed a motor this thoroughly clean. Seems like it just came off the assembly line.Amongs
