Holley Terminator X EFI

[flexmerc]

All here is the idea, has anyone done this and/or is it possible. I want to build a torque specific Ford 302 build using this thread. https://www.f150forum.com/f10/bit-info-those-looking-build-300-hp-5-0l-302s-276512/

Can I use a 1987 Truck intake with a Holley Terminator X EFI system
with the stock Fuel rail? rebuilt Ford 302, fairly stock...(stock heads, but upgraded roller Cam)

I believe the truck intakes are too tall for our Broncos.

thats fixable with a hood scoop or no hood, hahha!

but im more concerned about the technical aspects, can it be done?

 

[Broncobowsher]

Technically it should work. Physically it won't. No hood scoop around will cover that monster of a vertical intake.
Just use an Explorer 5.0 intake, they flow better anyway.

I have installed this kit with mustang upper and lower. The only thing "Ford" about the SBF Terminator X kit is the Injector plugs. Everything else comes with a GM style plug for sensors, you will need to change sensors and in some cases add adapters. Yes those intakes will work and the system will run, but there are better options for intakes.

Thanks 69 miller

Do you already have the Term X? If not talk to us. We have a couple NOS/NIB I can discount. When the Term X first came out it was plug in for FORD. Not any more. I pulled them from the site. To many extra and random parts to track down but Morgan can give you a list if you want to go this way.

I currently have a Holly sniper EFI. I haven't had a whole lot of issues aside from the O2 sensor constantly going out. I'm looking for a future solution EFI that is as close to OEM but not a 20-year-old system.
I figured since a lot of of these race trucks and cars use the terminator X it has to be more reliable?

My current set up is a Holly sniper EFI gen 1 with the hyper, spark distributor, and a crawlers edge 23 gallon EFI fuel tank

I can't speak for long term reliability since it's only been installed less than a year. I do know if you are into the tuning portion you can tweak just about anything you want with the Term X. I was already running the fox body Mustang 5.0 EFI so the Term X seemed like a good way to go. In typical fashion we spent $1500 or so fixing a $200 issue. Just make sure you have a good fuel pressure regulator to begin with. Hit up Morgan@wildhorses4x4.com if you want any specifics about the install.

sensors dyeing is contamination; oil or some aspect of the engine has silicone gasket material or other bad things for sensors.

 

[flexmerc]

The engine is the only mechanical part I haven't touched yet; I'm in the process of having a 302 rebuilt at this time.
It could be an issue with the engine, but everything else seems solid, compression, oil pressure, it doesn't burn oil...etc BUT a lot of typical leaks and it's completely unknown history

 

[Broncobowsher]

Something as simple as the wrong RTV on the intake manifold will kill O2 sensors.

As well as a few other things. Laying in the wrong position as it screwed into the exhaust tubing for one. Being too far away from the exhaust port to heat up efficiently might be another. In addition to the things already mentioned.
