I bought my MRS 3sgte again in 2020. Parker from NW Motor s called me and informed me I was acquiring a one-of-a-kind, clean 3sgte motor. and he didn’t lie. I’ve got the pictures to establish it in advance of installation. I have never found a motor this cleanse. Appears like it just arrived off the assembly line.Bought 3rd B16B swap from J&Jmo
