Bought my donor vehicle finally - a 2000 mountaineer with the 5.0. I'm pulling everything I need and selling whatever I can to wrangle up some cash for new fuel tank, pump, and the other parts I'll need.

http://www.archlinewebdesign.com/mountaineer

here's the photos. 175k miles, trashed on the inside, but motor sounds good and no smoke. We'll be able to tell more when I dig into it. The heads are coming off and the pan to check the bearings and cylinder walls.

I'm pulling these parts that I might use one day and selling/scraping the rest:
Engine (including harness & accessories)
Transmission and all connections/hoses, etc.
Radiator (don't think I can use this however I'll grab it just in case)
Rear View Mirror
Intake Airbox
Fuel Pump & wiring harness
Seat Belts
Coolant/washer fluid Tank
Fuse box and relays

Am I missing anything? I need to make sure I get all the sensors and stuff for the EFI.

So far I know I need a new MAF and ECU to get the EFI to work, I might try to rework this harness...what else from 87-93 mustang efi will I need? Does this throttle body work?

You'll need a distributor w/TFI attached. I pulled one from a 90 Town Car over the weekend. I called our Carquest & I can get a new one for only a little more, so I'm going to return it. I get our dealership's discount on parts prices, so it may not work out that way for everyone. I may keep it for spare parts, I don't know. I could use the $50.00 elsewhere.

Not sure why you'd need a new MAF. The explorer one should work just fine & it'll be located inside the airbox. If you're not going to reuse the airbox, just take the MAF out and use it. If you end up getting an RJM harness, just check your connectors on your sensors and injectors and make sure he makes you one with the correct ones. This is what I did and I just need to get off my arse and install it all as it's been in the original box for 1.5 years!

Throttle body will work great and it's larger than the stang. Explorer TB = 65mm = GOOD!

Is the maf from that usable with the 88-93 computer?

I would think so with the right connector on the harness. I think the biggest issue is running the correct injectors for the MAF. Explorer 5.0s all had 19#/ hr injectors as far as I know so as long as you've got the orange injectors, explorer MAF w/ the appropriate style connector on the harness should be golden.

I was informed that the Explorer/Mountaineer MAF will NOT work with the mustang computer. You want any MAF from a 87-93 mustang. They are all interchangeable in the housing so you wont have to buy a new housing.

The link you provided said that you have to reprogram the mustang computer to work with the Explorer maf.

Damn! I guess I was being overly optimistic when I read that. I was thinking if you ran 19#ers you wouldn't have to reprogram anything.

OBTW, those MAF sensors fit real nice in your pocket when junkyarding. Easy way to get your $2 admission fee back... so I've heard...;D

I think there is still some debate regarding the Explorer MAF & even the 94-95 Mustang MAFs. I was reading here:
http://classicbroncos.com/forums/showthread.php?t=175289

Draw your own conclusions. Looks like the Explorer MAF is significantly different than all the Mustang MAFs.

I was not able to locate a 95 Mustang MAF at the yard this weekend. I found a 55mm that crosses to a 91 Mustang. I'm happy not "experimenting" just yet. Plus, untill you start pushing the envelope, the 55mm MAF is totally adequate.

So are you saying that the explorer housing is okay with a mustang sensor in it?

Yup...did it on mine just the other day. The Explorer 70mm MAF housing is the same as the 93 Cobra MAF housing.

As long ay you realize the MAF calibration is a combonation of the sensor and the housing. The sensor takes a sample of air (sometimes called the sample tube) which is a fraction of the air flowing through the housing. measures the amount of air, converts that to a voltage and sends that to the computer. Computer takes the voltage, looks up what mass of air is going through, figures how much fuel (and spark) the engine needs, looks up the injector size and figures how long to turn the injector on for. Get one part wrong and it won't be happy. You can get lucky. I had a U4P0 computer ('95 mustang) with an 80mm Lightening MAF and 24 Lb injectors. None of those pats should work together but it would start, run and drive around OK. If you didn't know any better you would think that mixing stuff up doesn't matter. But it did run a lot better after a dyno tune to match all the parts up. So when someone says that this and that in here will work, it might, and it might drive OK, but that doesn't mean it will drive correctly and to the full potential. I have seen some really messed up tunes that still drove good (pouring black smoke rich under full load) and it was happy and would even pass emissions.

you know you got a rear disc conversion in your possession too right?

I didn't even think about the rear brakes, I'm assuming they are disc, didn't think they would fit the old 9". I'll have to do some research on that. So I'll keep brake lines, calipers, brackets, anything else needed for it? I have a '77 with drums now.

They can be made to fit. Currie enterprises sells the explorer rear discs as a kit. They sell the rotors already drilled for the correct lug pattern and the rear wheel bearing spacer that will be neded. Then you have to redrill the explorer backing plates to fit the 9".

I have been reading up on this as I picked up a 97 mountaineer.

Yeah was just reading up on it myself, sounds do-able, bu not bolt on for sure. I'll grab the parts now, and put that in the 'do it later' pile for now. Drums work just fine and would rather upgrade to hydroboost.

'77 has the bigger drums. With the front disc, it will probably stop fine unless you go with a 35 or larger tire. I am keeping my rear disk set up from my donor just in case.:cool:
