WHAT DOES JDM HONDA B16B ENGINE FOR SALE MEAN?

I bought my MRS 3sgte back again in 2020. Parker from NW Motor s referred to as me and informed me I had been obtaining a just one-of-a-type, clean up 3sgte motor. and he didn’t lie. I’ve got the pics to show it prior to installation. I have not seen a motor this clean up. Appears like it just came off the assembly line.This engine is wonderful
