Or do it the easy way. Buy a set of jenvey quads webber pattern and they bolt straight on. For 1K from Competition Systems in Melb you can get quads linkages and fuel rail. I did mine it wasn't that hard.

Its not as simple as grabbing a heap of parts and slapping em on to the motor.

i am in the process of this also, and its a lot harder than it seems. It always is isnt it.

Your shoppinng list would include at least

4 injectors, correct size for motor
a custom manifold with bossess set at correct angle.
throttle body and custom plenum chamber
computer
a pallet of paitence
rising rate fuel pump (if turboed) or an efi fuel pump
custom fuel rail, with return lines installed.

plus lots of other stuff that I havent worked out yet, which I am sure that someone else can add on
