Explorer Intake questions

[JJBroc]

Hi All,

I have a few questions I hope you guys can help me with. As mentioned before I am building a Factory Five AC Cobra. It has a 1989 Mustang GT drive train, 5 speed. I bought a lower and upper intake setup off a 2000 Ford Explorer. And I am using the Explorer’s 65mm TB (used the ball off the 58mm Mustang TB) and Explorer’s injectors ( I think they are bigger than the Mustangs and bought the adapters to use the Mustang harness with them) as well.

My questions are:

Can I relocate the ACT sensor to the air intake tube between the TB and the MAF? Has anyone experienced problems doing this?

I do not have the MAF from the Explorer. What should I use with this setup?? Is the Mustangs too small? Should I go to a bone yard and hunt down an Explorer MAF? Or buy aftermarket?

Seeing as the intake is a 2000 I am planning on removing and bypassing the EGR and blocking off the holes with a plate. I have an EGR spacer with the coolant line coming in from the heater tubes. Where should I send the coolant after it leaves the TB???

Thanks for all the help!!!

Did you hear about relocating your ACT on the Stang forum? I have heard it will allow the ECU to run in a little more aggressive mapping mode due to the cooler air readings but it really raises the question of why would it be located in the lower intake in the first place? I can't verify that it gives your engine more power as they say but it is being done. They also say run premium and stay around 14 degrees basic timing if you do that. If you do move it, be sure to solder the wires at slightly different locations and heat shrink them (connections not side by side).

Match your MAF to the injectors (calibrated for one another) or it won't work well. The matched MAF tricks the ECU to run a curve that is at a different A/F ratio than the stock for the new injectors which will supply the correct amount and timing of fuel (more).

Still have my EGR connected but there are various ways to overcome that. Don't have a coolant line to mine. Sorry can't help you on that one.

Aren't EFIs fun!!! Good luck, WEK.

Thanks for the response, it sounds like the direction I'm heading in. Like you guessed I've been on the mustang sites and have seen some of their tricks. I just want this car running and on the road. Kick myself at times for not just going 4 barrel. Thanks again

Hey JJBroc,

You will be very happy with your choice after you get past the hard parts which is the hookup of the sensors. I have had no issues with the EFI except for adjusting the throttle sensor to optimize, getting the idle where I wanted it, and adjusting the basic timing a couple of times. It was recommended to move the timing up a little at a time until it runs best. I'm at about 13 degrees now. But during the whole time, it has been running pretty nicely. With a carb, I have had more work after the start to finally getting it the way I liked it. You can always go back to a carb if you change your mind later. Good luck, WEK.
