What does the b16 longblock consist of? Passwordjdm is selling b16 longblock for 570 and what else do i need to complete the swap?

 

why not just call and ask them.
for long block it should included a complete swap EXCEPT for:
-tranny
-mounts
-ecu
-axle
-shift linkage

wiring harness sometimes is or is not included depending on the supplier.
