We had to double up this 5mm adapter plate and mount the 80mm Mustang throttle body upside-down in order for the throttle blade to clear the manifold internally. This way the throttle blade directs the airflow down and into the belly of the intake manifold plenum as the throttle opens.
As we fabricated the intercooler end tank, the new location of the throttle body was perfect for a really clean packaging of the intercooler.
We needed to fill the holes around the intake manifold adapter. This led to the decision to create a new billet adapter plate that we would weld to the intake manifold. We 3D printed the outer shape of what the adapter plate needed to be and made clearance for the adapter plate that was already tacked to the manifold.
After some time playing around in Fusion 360, we made a much more attractive throttle body adapter.
We 3D printed a test piece that matched the contours of the Mustang throttle body and thought it looked pretty good.

Very clean installation.
I like it when modifications are thoroughly thought out.
Any plans to replace the fuel rail crossover hose? Those get nice and crispy after 30 years of use.
Yes, the entire fuel system is going to be replaced and upgraded in a future article. Stay tuned!
This project is heating up! Excellent work and execution. I can’t wait for the next update.
So sick, bro.
I’d love to see an article about DBW and throttle mapping!
We could do that; there is a lot of information on HPAcademy.com though.
Not that it is necessary with forced induction here, but wouldn’t independent throttle bodies eliminate the space issue entirely? Gorgeous work either way.
While ITBs would eliminate space issues, it will cost (depending on which brand ITBs) $10K – $15K – $20K or more to have a DBW ITB setup with a custom plenum for forced induction. Our solution of cutting the stock intake manifold, making a billet adapter plate and used Mustang throttle body was around $500.
