I'm a junkyard junkie man
. I can almost guarantee that you will not find a B16A or B18C or H22. If you do, pull it out as soon as you can, becasue it will go away quick. All Honda engines have their engine codes stamped. Like pdiggity said, anything less than a B18B is no score but that is your decission. These are what I consider great score:
H22A
H23
B18C5
B18C1
B18B
B16A
Any Turbo
DSM 450cc injectors
Honda ECU's (OBD1/OBD2) and harness
Any Turbo
Starion/Conquest intercooler
Civic standard/CRX HF headers (great for turbo manifolds on D15 and 16)
Supra pistons
Supra injectors
Integra rear disc brakes
GSR and TypeR rims
Keep these in mind. These are great sell on ebay too.....Goodluck
