I found this online while looking for info about adding the EATC from an Explorer to a Sport Trac. Thought y'all might be interested in it, especially anyone who is considering transplanting a V8 into their Gen 1 ST.



V8 swap into Explorer Sport



Vehicle: 1999 Ford Explorer Sport w/ 4.0L OHV, 4.10 gears, and ~45k miles



Donor: 2000 Mercury Mountaineer 5.0L V8 Rollover, ~43k miles



Parts needed:

-Complete explorer V8 engine with all wiring, vacuum hoses and accessories

-V8 engine mounts (V6 ones work, but the V8 ones are slightly larger)

-Starter motor

-Stock V8 exhaust with O2 sensors and cat converters (or go custom if you like)

-Engine bay wiring harness

-Radiator & hoses

-Brake booster

-Cruise control servo

-Throttle cable

-Trans Shift cable

-Cruise control cable

-Complete 4r70w transmission with sensors and wiring

-Transmission cooler

-Transmission cooler lines

-Power steering lines

-Power steering cooler

-Hard AC line that bolts to compressor and goes to the dryer and condenser

-A few extra bolts to mount trans cooler, wiring harnesses, wiring brackets.

-AWD transfer case (not needed for 2wd)

-Front driveshaft (not needed for 2wd)

-Shortened 4 door V8 rear driveshaft to fit the sports shorter wheelbase

-2wd GEM (behind and left of radio), ECU (engine bay), PATS module (above Pass. Airbag), and a key. All these need to be from the same vehicle except for the GEM in order to avoid going to the dealer for programming. If you want to use your existing key, then you only need the ECU and a trip to the dealer for programming.



Modifications I did:

Some paint & new bolts

Comp cams 986 springs with retainers and locks

Comp cams 349 cam

1" Trick flow upper intake spacer

Torque monster headers

TransGo Shift kit for 4R70W

FMS Double roller timing set

FMS metal lifter guides (to replace the stock nylon parts)

1.6:1 Roller rockers

FMS cast aluminum valve covers (no purpose really except to look cool and possibly clear rocker arms)

Taylor Plug Wires

Fel Pro gaskets

FMS head gasket kit with bolts (gaskets are made by fel pro though)

Alternator from a sport trac with 23k miles or so



One thing to note about this swap, is that it is 100% bolt in if you have all the right parts. All holes are drilled in the frame/engine bay area for the new wiring clips, trans cooler and other brackets. The way I recommend doing this swap is to have a donor vehicle. It is so much easier and you are guaranteed to have all the necessary parts



Pics:



I spent a lot of time working on this motor before I actually started taking apart my X to swap engines:



After the first full day of work, we had the engine out:



Next I did some undercoating of the trans tunnel, rust repair in the engine bay, and cleaning. Then I installed the V8 engine bay harness. I find this to be a necessary part because the engine wiring connector is located in a different spot from the V6 to V8. I didn’t feel like extending all the wires, since I had a complete harness. Also, this harness was wired for the EATC system and message center, which I had installed earlier, so having factory wiring for that is a big plus. I also came to a problem when I started to install the V8 power steering lines that I bought from fast parts network. They fit fine, but for some reason my power steering cooler wasn’t lining up with the lines! I said oh crap, because I had sold my power steering cooler way back to a fellow member. I did not realize that they are different. I immediately ordered one from ped5stang, and decided to make my current one work for the time being.





Once this was all complete, a friend came over and we replaced the head gaskets and checked for debris in the combustion chamber. The engine was sitting around a good bit and I wanted to make sure<

Same as those of its sibling, the Explorer. Here ya go:



Engine Size: 5 liters/302 cubic inches

Horsepower: 215 hp Max Horsepower: 4200 rpm

Torque: 280 ft-lbs. Max Torque: 3300 rpm

 
Thanks TrainTrac. The swap is truly a labor of love. Because that's a lot of time, money, and sweat for some extra torque. But bragging rights would be off the scale in the Explorer Sport and gen1 Sport Trac world, not to mention authentic V8 rumble.
 
Lets not forget. Putting a V8 in it is more than just the torque. You have the ability to add any go fast goodie anyone has on the shelf.



The 302 can be built to over 500 HP for darn near nothing. You can push over 750 HP if you want to invest some cash. The sky is the limit.

I wonder if you could take the AWD setup off the mountaineer and put it in a 2wd ST. If I were to do a swap like this in a 4x4 ST I'd seriously look into making it an AWD street machine.
 
I'll be it could be done, if you had all the necessary parts from the donor vehicle. It would be quite an undertaking, though.
 
ALSO remember some states , Such as NY, it is against emission law to install and OLDER Model year motor in a vehicle and get it inspected. This does not apply for vehicles built before 1983 or so, they are exempt. This goes for OBDII cars and trucks...



Yes, everyone knows somebody that my get it to pass, But keep in mind there are other factors you may run into..

TrainTrac, I have an EATC module out of an Explorer that I'll sell if you haven't gotten one yet. I think I paid $100 for it. I can't remember for sure why I have it left over, but I know I tested it and it works great. I think I found another complete setup after I bought the first one. You would still need to get the blower motor variable resistor the blower door control.



I'll tell you that it is a painstakingly slow project. I have a bunch of pictures from when I did mine, but never got the project written up. Now, it's been so long that I don't remember where the drawings and stuff I did are, but if you have any questions about it I'll do my best to help.

After looking in my library, I realized that most, if not all, pictures you will need are in there along with the original wiring diagrams of the EATC and the ST.

As Caymen said, there is alot of aftermarket out there for the old push rod 302. I pushed my '94 stang to 376 rwhp natural aspirated for very little $$. Started with a 302 from a mustang cobra doner...

Doug,



You have e-mail. Not to take my own thread off track, but I found this EATC project on another site. It's for a Ranger, but I don't think it's all that different for a ST.
 
Back to the original topic...

If $$$ was no object, I'd start with a crate engine from Ford Racing Performance Parts, and build it up from there. Maybe add a S/C and then the AWD system that R1ch mentioned. It would make for one helluva ST!:cool:
