So I have a d16y7 with the shitty intake manifold on it that goes up towards the hood in my 2000 hatch, I was wondering what was all needed to put the d16y8 intake manifold on the car. It obviously will flow better but what is all needed?

The only thing I have is the intake manifold but I need a throttle body that will fit it and gaskets of course, what else do I need? I'm trying to squeeze as much power as I can out of this SOHC without sacrificing gas mileage and spending too much on the motor, just wanted to change that horrendous intake manifold and clean up the bay a little bit.
