    Hey everyone, I purchased a 1993 4-cyl. notch a few months ago with the intension of converting the coupe to a v8. Little did I know the true magnitude of the process that is involved to do the swap right. For those interested in doing this conversion, I encourage you to source a factory v8 coupe, but if you insist on tackling this swap, there is what's involved;


    Items that are different;


    Front spindles
    Front sway bar
    Front strut
    Front brake rotor
    Front brake caliper
    Brake booster
    Brake master cylinder
    Brake lines
    Fuel lines
    Headlight harness
    Engine harness (specific for model year, my 93' needs 93' specific harness)
    Engine computer
    Gauge panel
    Rear axle (of course)
    Rear lower control arms (no provisions in the 4-cyl. Lower control arms for a sway bar)
    Transmission (in my case converting from auto to auto)
    Transmission shifter assembly (AOD has "1, D, OD", A4LD has "1, 2, 3, OD")
    Radiator
    Radiator fan assembly
    AC system
    Exhaust system
    Intake system (harness will also depend on MAF or Speed Density)
    Steering rack (v8 has a quicker steering ratio)




    My best advise in this case would be to find a DONOR v8 car to strip. This is exactly what I did! I purchase a 1990 Ford Mustang LX convertible, with an AOD. I later sourced the proper 1993 engine harness to accommodate the conversion.


    So, here is my spreadsheet of modifications that will be taking place prior to the swap;


    Retaining stock short block
    Port GT40 iron heads (by Mustang Mike) * more info later
    Port Ford Explorer intake lower manifold (by Mustang Mike) * more info later
    Port throttle body opening for 75mm EGR spacer
    70mm throttle body
    76mm MAC MAF housing with 24# injector sample tube
    Ford 24# flow matched fuel injectors
    Retaining stock airbox, and intake plumbing
    AFE air filter (superior to K&N)
    Crane 1.7:1 roller rockers
    Ford F303 cam
    Titanium retainers
    130lb seat pressure springs
    Ford Racing Hardened pushrods
    Ford Racing oil pump shaft
    Ford Racing oil pump
    Ford Racing head gaskets
    Ford Racing OE lifters
    ARP head studs
    Double roller timing set
    MAC 1 5/8" equal length shorties
    SVE 3-row aluminum radiator




    Stock cat'ed H-pipe (for now)
    Stock AOD and stall (for now)
    Donor car has flowmaster cutback which will be retained
    Donor car has 3.73's in the 8.8"
    Retaining fan clutch and fan blade (for now, all new)
    Solid motor mounts
    Poly trans mounts
    5-lug SN95 conversion w/stock rotors and pads (for now)
    Poly front lower control arm bushings
    Moog lower ball joints
    Eibach Sportline springs
    Eibach sway bars
    Koni STR.T
    Maximum Motorsports caster/camber plates
    Lakewood "traction Action" lower control arms
    Retaining AC
    Retaining power steering
    Retaining all emissions provisions


    Future plans;


    3,000-3,200 non-lock up stall converter
    Lenntech, or PA or Art Carr valve body "hold gear". Auto/manual
    Trans cooler
    Off road x-pipe
    Larger plumbing for intake track, retaining stock air box
    Electric radiator fans
    Subframe connectors
    Maximum Motorsports Torque arm
    Pan hard bar or watts link

    nice, a little more involved as far as interchangeability than I would have imagined.

    I agree! Some of it doesn't make sense to me, in terms of tooling cost involved on Ford's end. After the foxbody, I think ford figured that out and started standardizing some of the hardware starting with the SN95 (spindles, etc.)

    that's one thing Honda does right (I guess they still do) that I wish ford did. you can take the head off car b (different size engine) transmission from car c, 6th gear from car a and use it in transmission from c, computer and o2 sensor from car d, intake manifold from car e, cam from car f and throw it all on car a.
    how much lighter is that sway bar... the factory 5.0 one feels like it weighs a metric ton.

    nice, I would say I would change the thottle body to a 75mm being its ported opening for 75mm / egr yet your running a 70mm tb, its always good to match the opening to the same size .

    My builder (Mustang Mike, listed in the original thread) discussed with me that the 70mm TB with the 75mm spacer was the ideal combo. You want to match your hardware when building a motor. Bigger would have resulted in low-end loss. Same concept with the headers and exhaust. He sees better results with 2 1/4" piping over 2.5" piping in stock E7 head application. In fact, MAC's 1-1/2" equal lengths yielded the most power. I've gone with 1-5/8" in because we're running GT40 heads, intake, and a decent cam. I'll likely stick with 2.5" for my system. Bigger isn't always better after all.

    Really focus on calculating every dime for the parts you'll want to, or will need to be replaced prior to taking the next step. It's far cheaper to find a true v8 car. With that said, the end result should be nicer (with personal touches, etc.).

    Yeah I bought my car as a roller for $500 and it had black interior already. Since my cobra blew a head gasket and I decided to part it a lot of stuff ill be transferring over like the rear end, brakes, calipers, lowering springs. Fuel pump (maybe) and some other stuff. Plans right now are for a 351 HCI motor. Just something fun with some chop to it :)

    The funny thing is that the fuel pump is actually the same between 4-cyl. And v8 (302). I would say "since you're in there", you might as well replace the fuel pump as well. A 255/LPH would do just fine. Especially with the 351. I also wanted to do a 351 swap, but for now, trying to stay on "some sort" of budget, the 302 will have to do.

    Yeah I'll be swapping in the lethal 340 pump from my cobra into the coupe. Overkill yes but I already have it so that will make it easier.

    Motor coming together, trying to stay with grey colors to make it appear stock! lol

    IMG_3575_zpscc9dfeb1.jpg

    IMG_3576_zps045535f3.jpg

    Titanium retainers, 10 degree locks, hardened pushrods, 1.6:1 crane roller rockers. The details make the difference!

    IMG_3577_zpsb125135f.jpg

    Equal length 1 5/8" shorties (MAC);
