We added the NSX logo to the plate and an integrated o-ring so we would not need to use messy RTV silicone to seal the port.
The new EGR blockoff plates look quite good on the car.
With the fuel rails and repurposed EGR to brake booster fitting mounted, we were ready to install the manifold back into the car.
The engine bay was ready for the intake manifold to be reinstalled.
We dropped the manifold back onto the engine and started to button it back up. The DBW wiring harness that we developed in Part-18 plugged right into the Mustang throttle body which allows the Motec M150 ECU to control the throttle for idle control and throttle response.

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.
