ECORS Class A race rig build

Began putting the upper engine stuff together. I torqued the intake down and got rid of the cast intake elbow for the Explorer intake. I can't remember if i posted this before or not, but I did tap and plug the EGR hole in the upper intake where it meets the lower intake so that exhaust gasses would not be directly against the throttle body.




Next, I welded the linkage arm for the BC Broncos throttle kit onto the original Explorer throttle body arm. It should work fine and was a lot quicker than trying to remove the original arm and attaching this one. Turns out that the BC kit actually fit ok how I did it. I am not overly fond of their long and stiff return spring though. I can't quite get full throttle out of it. I did have to heat and bend the throttle pedal a little bit as well. The EFI setup uses a lot more pedal swing than the linkage type carb setup does.




Here is the throttle body bolted up. I had to use the original TPS sensor, as the bolt holes were different for a Mustang type TPS. From what I have read, some actually will interchange. My luck once again was for the worse... So, we used the original TPS connector from the Explorer harness. We also used the original IAB plug from the Explorer harness, as that was different as well. If you do the Explorer intakes and such, keep this in mind and try to get as many of the electrical plugs as you can.
