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".
