WHAT DOES HONDA B16B ENGINE FOR SALE MEAN?

I bought my MRS 3sgte again in 2020. Parker from NW Motor s referred to as me and informed me I used to be getting a a person-of-a-type, thoroughly clean 3sgte motor. and he didn’t lie. I’ve received the pics to establish it ahead of installation. I have never found a motor this cleanse. Appears like it just arrived from the assembly line.Aweso
