So I found a possible source for intake runners.
Waiting for it to come in the mail.

According to the ebay listing, it's from a 06-08 kia/hyundai 2.4L
It has a separate plastic plenum.

76963


And this is why I bought it.... Look familiar?
Even if it doesn't fit, and is "just close" It would be easy enough to port it to fit.
A new plenum and venturi horns will be easy enough to fab up separately.

The BK1 intake manifold with OEM BK1 gasket


The Kia/Hyundai 2.4L intake manifold with BK1 intake gasket.


The top part of the 2.4l manifold flange, has like a millimeter or 3 less meat but plenty enough to not be a problem.

The manifold on the engine, without the silly plastic intake plenum.

If I had to guess the plenum side runners are about 1/4 larger than the other side...
Basically they taper down (cone of sorts).
Runner length are close enough to be about the same as the BK1 manifold.

Because of the angle the runners sit at, I've have to redesign the plenum.

Same principle at the other one I made, but upside down.
The velocity stacks are offset from the center.
A majority of the air is suppose to hit the back of the plenum, swirl behind the velocity stacks, and aim back to the throttlebody, where the additional air from the throttlebody will aid in aiming the looped air directly to the velocity stacks for more even air distribution to all 4 runners.

like the cosworth escort intake manifold design (but upside down)
This is all because of the dimensional constraints (I don't want to smack my hood against the manifold)

Still have to export as an stl file and then run some flow tests sims. (I could have made it a bit simpler :p)

Mark 7 intake manifold plenum....

The odd shape is to because of the limited space. This is design to slide onto the 2.4L runners.
There is plenty of empty space under the stock intake manifold.
The main constraints are the upper radiator hose hard pipe, fuel rail clearance, and the stock throttle body location. The stock location has the TB in the path of cylinder 1.

No updates, been waiting for the snow to melt...
Considering that it decided to dump over 2 feet of snow, it may take a while....

I want to get actual measurements before I start fabbing. I may have to move the driver side fuse box over a bit, or completely relocate it.
Also might need a BK2 powersteering pump, to make more move on the passenger side, so the intercooler piping doesn't snake all over the place.

Any updates? You reminded me of this from the other thread when you mentioned the intake mani balance.

I got some velocity stacks, but the inner diameter of them are 1mm too small.
Also port matching...
