You gotta take off the intake elbow, Throttle body, expansion chamber, and VDI manifold.
The Intake elbow is held on by 2 12mm bolts. The TB is connected to the expnasion chamber by 4 12mm bolts. Make sure you disconnect the throttle cable and all the vacuum lines before removing the TB. The Expansion chamber connectgs to the VDI by 4 12mm bolts and 2 12mm nuts. You'll have to remove a few more vaccum lines here. Now you need to remove the 2 12mm bolts that hold the secondary fuel rail down onto the VDI manifold. Then you can pull up on the fuel rail until injectors pop out. Now you should be able to remove the bolts holding the VDI onto the Lower intake. Once the VDI is removed, you will see the primary fuel rail connected to the lower intake. Remove the 2 bolts holding on the primary fuel rail, and pop out the primary injectors. Just make sure you label all the vaccuum lines so you don't get confused putting everything back together. You might want to order all the neccessary o-rings, grommets(for the fuel injectors) and the gaskets for the manifolds.
