M50B25 manifold

[BMW_318TI]

I am planning to buy a used 323TI Europe version.
While just searching through the forum:-).
I've read you can use a M50B25 manifold on the 323TI motor.

Now my questions.

1.Do I only need the M50B25 manifold, so ejectors, throttle house etc are useless?

2.Anyone have the tutorial for it, or some pictures?

Thanks in advance!
