might want to add piston rings, wrist pins, connecting rods and a head gasket.

i thought you were going turbo? header is NA downpipe is turbo
and turbokit should come with a downpipe.

also a good starting point but if doing a rebuild id suggest
some injecters as well. If you have the engine to handle the boost get the fuel and BOOST!! =)
