5.0 Sport Trac Lives

[ttbit]

Uh oh...I am getting the itch for more power...

Did you use the SpeedChanger II module for your VSS signal? I was curious as to how that would work with the late 01-05 Sport Trac. I know that the late 01-05 ST got its VSS signal from the PCM which transmitted the signal through the C110 connector and on through C146 connector at the firewall. Where as the early 01 ST and the EXP PCM receives the VSS signal from the ABS module.

My question if you use the rear abs sensor on the rear axle as a source for the Speed Changer II does it have any effect on the existing ABS? Also where would you cut and ground the VSS signal? I know the SpeedChanger II VSS signal would then have to tie back into the C146 or C110 connector at the GY/BK - 679 circuit wire.

I didn't have to do any of that. I just had to make sure I separated my PCM's VSS from the vehicle's. The speedo, abs, etc, all work fine. Mine must be getting everything from the rear diff. I can't remember if I confirmed having a late or early 2001. I thought I had a late model. It has been some years since I have done the conversion now. I can double-check, if anyone is interested.

I am as I have a guy lined up to do the swap for me soon. I have a wrecked Mounty V8 lined up. Mine is a 2001 job 2. I am planning on having my running engine put in a 2001 job 1 that I bought off CL with a bad engine. I am trying to get him to read this thread before he starts. Might be asking some questions once he gets started. He will be doing the work near you, down Calderwood Hwy..

 

[ttbit]

Mine was built 04/2000. Seems early ST's are easier to convert. I think I got lucky all the way around. My 96 PCM has no PATS and I didn't have to deal with VSS issues. I am still running a stock PCM. No tune. Let me know if you have any other questions. Are all the 1st gen v8 Sport Tracs in East Tennessee?

What year is the Mountaineer? The Job 1 would be an easier swap for the V8 it already has the correct PATS B, and VSS circuit. You could swap the 5.0 in the Job 2, but you will either have to do away with PATS in a tune, or add the PATS B module, and transceiver from the Mountaineer and wire them into your Job 2, as for the VSS you will either have to use the ABS module and GSwitch from the Mountaineer, a 2001 Ranger 2.5 GEM module, or something like the Speed Changer II Calibrator for the VSS signal. You may also be able to transplant the ABS from the Job1 Trac into your Job2 and vice-versa.

You will also need to swap some wires in the Trac's C110 connector to match the C115 connector from the Mountaineer, as well as a few wires in the Mountaineers C125 connector to match the Trac's C139 connector. There is a ground wire also needs swapped for the tachometer to read correctly. You will have to modify the alternator harness, and I am not sure but may need to extend the wires on the AC high pressure switch as well. I been doing some research on this swap myself for 2001, have some notes saved, but RangerSVT knows his stuff, he may be able to help you out.

 

[just1me]

I thought yours was a Job1 ttbit that is much simpler to swap a 5.0 into. The Job2 requires a couple extra steps the VSS signal, which I been researching and it seems Ford may have used the same ABS module for the 2001 - Job1 and Job2 but on the Job2 pin 19 is a dead wire, instead of gy/bk that sends out a signal, its a black wire that goes nowhere. I am curious as if anyone has tested this wire yet.

You also have to deal with PATS, because the Job1 was PATS B, but the Job2 was PATS E. I wonder though did you have to ground your starter relay in your Trac when you swapped over the 5.0? I noticed on the Explorer/Mountaineer with the starting circuit that the starter relay is grounded, where as with the Job1 Trac it's grounded through the PATS B module, and the Job2 Trac with PATS E it is grounded from the PCM

Nope.

I was the only one doing a 5.0 ST swap at the time, and was concerned, after reading what people had to do with the later Rangers, that I might have some issues. I wasn't seeing the problems in the schematics and just really lucked out. I think I had one code in the EEC from a wire I had to ground and that was it. The 96 Explorer and 2001 ST were just the vehicles that I ran across. It wasn't planned that way.

I studied those schematics for some time. I don't remember much now and sometimes go back in this thread to find answers for people when they email me.

The Mounty I am buying is a 99-01, don't have the title from the guy yet so not exactly sure. My job 1 ST is not as nice as my job 2. I have already done several things to the one I want to keep. The guy doing the swap was a master tech at Ford for years and says he should have no problem doing the swap.

ttbit, what mods are you planning for the V8? I have thought about doing some stuff to mine before putting it in but am saving my go fast parts for my 94 Mustang GT.

 

[just1me]

The 99-01 5.0 shouldn't be to hard. Your Trac is 4wd right? You will either have to get the Advance Adapter for the 4r70w to retain your ST transfer case, which will mean the trans will have to be disassembled to change the tail shaft for the AA-adapter, or you can just use a larger 4406 electric or manual transfer case, the ST 4wd transfer case motor and wiring should be a direct swap to the 4406-e from what I been told, though the front and rear driveshaft will need to be modified or changed.

Well, the stock engine runs out of breath pretty early. I will probably throw on some better heads and cam to start out with. I considered stroking, but I don't want 12 mpg. I will have someone go through the transmission and put a shift improver kit in like a Baumann, which I have had good luck with in the past and a torque converter. Looking at what some people have done lately with positive displacement blower adapters makes that tempting. I don't want to give any advice on things I haven't done personally, so I will let you know after I mess things up. I have read a million things on different builds, but you just don't know until you try. I am still in shock that we only have one set of headers available and they cost as much as a used set of aluminum heads.

My only regret is leaving the engine stock, as it sat for quite a while. If I would have known everything was going to go so smoothly with the swap, I would have spent money on the engine. Now I have to pull everything out again. uuuuhhhhggg...

My last go-fast build up was my 95 GT. I had a Kenne Bell 1500 on it and edelbrock heads. It was actually really fun without the blower and just the heads, explorer intake and custom tune (by me) too. Fun cars and lots of easy mods to make them so much nicer. The newer vehicles I have owned were not as happy with suspension or other mods. The sn95 platform just cries for modification...especially chassis and suspension. Have fun with that.

hahaha...Before I did my swap, people said it wasn't possible and now people are saying it shouldn't be too hard.

For the street, I have been pretty happy with my AWD, which just bolts into place. I am not going to advise on the 4wd conversion, as I have not done it, but there is a lot of information out there and people seem to be happy with it.

 

[just1me]

Rwenzwig and RangerSVT seem to have a lot of knowledge on the 4wd swap, but AWD is nice to. To be honest I don't know much about the SAS swaps though, or what they do with ABS afterwards, I never been much into offroading. I would think AWD would handle just fine though even in snow.

YES...it helps in snow tremendously. Great in the rain where our roads here get pretty slick too. I have been impressed.

Pics of my donor, it is a 08/2000. The front end is in pretty good and has the painted grille. It has 99k on it. I have already bought a 4406 transfer case so I can still have low range. This one is electric. I did the 4406 manual swap in my old Mounty and what a pain in the leg(literally) I don't want to do that again. My ST is 4wd, 4.10 gears open diff. I want to get the rear discs and limited slip from the Mounty also.

As far as performance goodies I don't know what I want to do to mine. Doing the V8 swap hopefully will be enough for a while. I also plan on gear swaps at some point. I have a set of AFR heads, Edelbrock upper and lower in the garage with plans of building a 331 for the Stang. I have though about putting that in the ST though. I had a Powerdyne supercharger on my gen 1 Lightning and loved it. Thought I might try one of those if I needed more power.

 

[ttbit]

Great! I would want the electric as well.

 

[just1me]

Yeah the 4406 electric is the way to go. The wiring differences between the 2000 and your 2001 Job2 isn't that bad. If you have the pinouts for connectors C110, C115, C125,and C139 you will be ahead. C115 and C125 are for the mounty, and C110 and C139 for the Trac. You will need to modify the charging harness to the battery junction box, the mounty used a megafuse, where the Trac used 2 fusible links. You may also need to extend the wires on the AC high pressure switch as they are in different locations from the 4.0 to the 5.0. The oil pressure switch wire will also need to be moved from C139 to C110 on the Trac to match the C115 connector.

Basically you want to repin the Trac's C110 to match the mounty C115 connector, and repin the mounty C125 to match the Trac's C139 connector. I have done a lot of research on this swap for the 2001 model. There may be a couple wires you wont need in the C115 connector like for the message center and air suspension, and about 4 wires that you wont use on the C110 connector that have to do with PATS E. I believe though you may have to ground the starter relay for the swap as with the 5.0 it is grounded, but with the Trac Job2 the PCM was the ground to the starter for starter relay control.

I know you will need though the high pressure power steering hose, throttle and cruise cables, A/C high pressure hose, radiator and radiator hoses from the 5.0. You will have to decide which way you want to go with the VSS, if you want to swap the ABS module and g-switch from the mounty to the Trac which involves extra wiring or if you want to use an aftermarket calibrator like the Speed Changer II calibrator for the VSS signal. As for PATS you can do away with it in a tune, or you can transplant the PATS B components from the mounty to the Trac, but you will need to do some wiring under the dash. I have some notes and diagrams for this swap.

 

[N2FORD]

Dropped the Sport Trac off at the mechanic today to get the V8 swap done. I will keep you guys posted on the progress. Might take a little while so be patient, that is hard for me to do. Thansk to all for the input and post that will hopefully make this fairly easy for him.

 

[ttbit]

Awesome. I'll look to see if someone is test driving a v8 sounding ST on 411 over the next days.
