k20a3 is rated at 160hp at the fly unlike the more popular k20a2 (200hp), the all mighty k20a1 (220hp), the new gen k20z1 (210hp), and the current si k20z2 (197hp).
what you need to swap a k into a civic are ecu (cuz the stock one has that immoblizer, most people go with k pro), axles, motor mounts (hasport has complete kits), power harness (k into civic use the ep3, k into integra use the type s), and a piggy back fuel system. could be more but these are the main things you would need.
