alright i was lookin into turbo kits and am gonna piece my own together.. i dont know what brands of parts im gonan use or what turbo but i jus want to know if i got everything covered:

turbo (derr)
ic with charge pipes
manifold
oil return line
tap oil pan for return
chipped ecu
bov
boost gauge
injectors (what size? 450cc or bigger?)

im prolly gonna go with a b18b with b20 head (inspired by homemadeturbo.com) and gonna get cams an pistons.. anything else i need for turbo setup or engine? thx
