The stock intake manifold has a ton of vacuum lines, idle control valves, ports, arms and brackets. Our new DBW manifold is significantly smaller and far simpler.
The stock 64mm throttle body is significantly smaller than the new 80mm Mustang throttle body.
It’s pretty impressive how much smaller and simpler the DBW throttle body is compared to the stock setup. We have a lot more room with the shorter intake manifold to fit our intercooler.
One problem with shortening the intake manifold was that we lost the brass fitting for the brake booster vacuum line.
We repurposed the EGR port for the brake booster.

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.
