8civic8, I purchased my engine from
www.nippon-motors.com
They have free delivery in southern california.
They usually come with the flywheel, clutch, intake manifold, exhaust manifold. Mine came with a distributor too. They'll usually have the plugs attached (when they were removed they just cut the wires). THis means you'll have to wire your harness yourself, but you'll have most of the plugs. I should be able to help you with any other plugs that you need.
