    As I tore into both vehicles I realized the harnesses are more different than I thought. would the SHO harness plug in to the ranger body harness? I already know i gotta swap the ecu itself but i've heard it plugs right in. I already assume I'll have to fab motor mounts but just in case ill ask, would mounts line up? and what could i do about the exhaust without getting a full custom one? last question might be more for a ranger forum but ill shoot anyways, how hard would it be to delete the twin i-beam and leafsprings and swap in the coilovers from my sho? its got nice ones that lower the car and it would go with the brakes and wheels better than stock ride height on the ranger. (sho has bigger sable discs all around and the ranger has drums all around. not doing a test drive without the disc swap haha)

    You will need the SHO wiring harness and eec computer. I can't think of another Ford vehicle that will plug and play. I haven't done this ever but I have yet to hear of compatible wiring harnesses. Larger Sable discs? Are they from a newer Sable/Taurus? This sounds like alot of mess. You have alot of work!

    sables of the same year had bigger discs because it was heavier. Like an OEM upgrade kinda.

    on the wiring, im asking if i need to make a body harness from scratch. yknow, everything that isnt between the engine and ecu. I already know im carrying over the engine harness and computer

    i just want to get it running first but when its done it's going to be a pro touring/daily type deal. planning on turbo(s?) and nitrous. sound system, aero stuff, coilovers etc

    i know superchargers are more popular because it lends very well to the power band, but with a turbo i could have it only come on above a certain rpm so that it isnt unwieldy and unpractical to daily it

    I might have seen 1 ranger on this forum and that is far back in the memory banks. I'll be following if you keep updating.

    I took a very hard look at this a few years back and decided it was way too much work. (And I've done a bunch of engine swaps, including putting a efi v8 in a RX7.) Ford did a show vehicle with a SHO motor in it, I've got a photo of it here somewhere on my computer, if I can find it. The engine was moved forward and the intake was heavily modified to make it fit. You will be doing a full custom exhaust.

    The motor mounts are nowhere near the right location. You will be completely on your own fabricating something there. You will also have to modify the trans mount if you move the engine forward, which I believe is required.

    You can take out the twin I beam from the front, but you will need to box the front part of the frame in that case, since the frame members are way too weak without that big crossmember. You will need all the control arms, etc. swapped as well, and trying to make a MacPherson strut suspension work in the front of the Ranger will be a challenge. Just the suspension swap is a rather large project.

    The wiring is substantially different between those 2 vehicles. You will need the factory wiring diagrams for both, and you will spend a lot of time sorting through that. Just to give you an idea - on the v8 swap into the RX7, I spent about twice as much time on the electrical stuff (figuring out wiring and then making wiring) as I did on the mechanical stuff (figuring out and making and installing). Your project will be similar in that regard.

    I'm not trying to rain on your parade, just trying to set realistic expectations. I've done a bunch of this kind of stuff, and you are looking at well over a hundred hours for wiring and another hundred plus for fabbing and installing engine and trans. If you want to do the suspension too, you are looking at that much more again. And I am talking about working time hours, not hours standing there scratching your head or getting parts.

    If you're willing to put that much work into the suspension I'd go with trying to get a mustang suspension in there. Maybe even spicing in the whole k-member if you could. Lots more options that way. But even then, your front would be vastly superior to the front so you'd have to look at how to make a leaf spring/shock combo on a solid axle handle well or scrap it and try to fab up a mustang axle under the rear.

    the intake can be turned around to fit, it fits both ways. if theres still clearance issues after that i have an angle grinder and a parts truck for a modified firewall

    The intake can be turned 180° with the use of spacers. It will not clear the timing belt otherwise.
