So do I need to us my old intake manifold on the new d15b motor or can I use the one that is on it? I was told that I had to use my old one because it was a mt motor and not a auto and that the jdm motor was a auto, i'm confused. I hopr i dont have to because the new one looks like it has a biger Kov

weather its auto or manual shouldnt matter as long as it hooks up on the side as the old
one. if your using a stock intake the the tubing for the new motor will work and so will the old motors
Intake manifold doesn't matter between automatic and manual.

In my EF when I swapped it out for a 5 speed the only thing I did to the intake manifold was take off the drop down cable.
