    Review & Installation Video

    Review & Install Video

    Well, here it is, our new project car, and as you can see I use the term new very loosely, you Fox body folks have been asking for it, so we’re going to give you a build unlike anything we’ve ever done before, we’re going to do a complete restoration on our 93 GT convertible, and you guys are going to be with us every step of the way. So what are our plans? Well, to say this thing is a little rough, would be the understatement of the century, we need to tackle just about everything there is on this car, I’m talking bodywork, paint, interior, headlights, and what’s left of our top just to name a few. Obviously we’re fans of just about every Mustang under the sun however there are a few that really get us going. One of these is the 93 Mustang Cobra, this was one of the first cars offered by Ford’s SVT division, and really set the tone as far as factory performance tuning is concerned however there was one problem, it was never offered in a convertible so we’re going to actually have a little fun with this build and make something we wish Ford had offered from the factory, we’re going to make our very own Mustang 93 Cobra convertible, which should really turn our tired old Fox into one bad little street machine. Before we get into the fun stuff, we need to take care of some much needed maintenance here on our 93, mainly the worn out and the 100000 plus drive train and body. So that’s the goal with this first step, we’re going to get our GT running like new again, and get the car ready for paint, because…yeah, we got a lot of work to do, so let’s get to it. Alright, 100000 miles of burnouts and hard launces has not been nice to our factory clutch, because it’s absolutely shot, so this is one of those areas where we’re not only going to freshen up, but we’re also going to upgrade, now our upgrade comes in the form of this Exedy Mach 350 stage 1 clutch, and the SR Performance clutch adjuster kit. This kit will replace our old, worn out, gummed up factory cable with this brand new adjustable cable as well as strengthen the weak plastic factory clutch quadrant with this brand new Billet piece. Basically we’re strengthening our overall shifting experience. Besides our beat clutch, our 302 motor is running extremely rough, we’re misfiring all over the place, and the power just isn’t there like it should be, so we’re going to give our motor a serious tuneup. Ryan and I are in the process of installing these iridium plugs as well as a new set of wires as well, on top of that we’re also doing a brand new distributor cap and rotor, and finally a brand new serpentine belt. All these parts should really get our 5.0 firing on all 8 cylinders again. As a little pointer for you whenever you’re doing a tuneup, we recommend using a little anti-seize on all your threads, just because you don’t want a stuck spark plug in your block. In addition, go ahead and throw a little dielectric grease on all your contacts, it’ll just help keep any excess moisture out. Unfortunately our slipping clutch and misfires are only part of the problem, when we were on the way back to the shop we noticed are car was running a little hot so we decided to overhaul our entire cooling system just to be safe. We’re ditching our factory radiator and mechanical fan in favor of this aluminum performance unit from Mishimoto, along with one of their electrical fans. This electrical fan will not only keep things cool, but by ditching that mechanical fan, we’re also going to free up some drag on our accessory belt, which in turn should free up some extra horsepower. To wrap up our entire cooling package we’re going with a brand new thermostat from Mishimoto, along with a new set of hoses from Ford Racing. Of course we have some performance stuff lined up after we get the car back from paint, but in the meantime we have to address this Frankenstein intake we found on the car, we’re going to replace it with this brand new SR Performance cold air intake which, besides giving us a nice little bump in power and sound, will more importantly get rid of this eyesore underneath the hood. Before we get out of the hood completely, we wanted to further reduce the parasitic drag on our accessory belt, so we decided to install this SR Performance smog pump delete kit. Could we run a smaller belt and eliminate the pump completely? Probably, but we wanted to do it right the first time, and clean up the engine bay in the process. Now that we’ve taken care of some necessary maintenance, let’s get to the next big part of the first stage of our resto. The only thing worse than the actual running condition of our GT is the physical condition, I’m not going to lie, this thing is pretty rough in just about every way, but that’s about to change, we’re going to send our GT off for some serious bodywork that includes a brand new paint job, but first, we need to take care of some problem areas. Some of these problem areas include a brand new set of smoked, one piece headlights, a new fender and a rear deck lid panel just to name a few but that’s not all that exciting, this is what’s going to turn our dream build into a reality, we’re going to outfit our 93 GT with a complete Cobra style body kit, along with this Cobra style wing, which when we’re done with our build, should turn our stock 93 vert, into one of the baddest, and possible one of the only, Foxbody convertible Cobras around. Well, that wraps up the first stage of the restoration here on our 93 GT, we took care of some much needed maintenance and got the car ready for the body shop, when we get the car back from paint, we’re really going to start having some fun with the interior and exterior styling, and of course give the car some much needed performance to back up that Cobra appearance, but in the meantime, I’m on my way to paint.

      Bad spark plugs

      We ordered the plugs they told us to get. Put them in and about 500 miles later they were burnt up . Put ford motor plugs in and no problem. I think you sold us wrong plugs.

      Wow

      I have a 97 gt and paired these plugs with ford racing wires and screamin demon coil packs and it really woke the car up. Way easier to change plugs on the SN 197 than the new edge. Prolly took about a hour and a half and I had to recap. Take your time

      NGK Iridium IX for my 95 Cobra

      This is my second set for my 5.0. NGK spec's call for .054 gaping, all 8 spark plugs were right on that spec. Fuel mileage is improved and the engine runs smoother and pulls stronger. American Muscle ships same day of my order. The parts arrive at my doorstep the next day Can't beat that!

      Worked fine

      Installed it along with MSD 8.5mm wires and MSD Coil Pack. Saw a 1 mpg improvement. No big performance gains in my opinion. They come out of the box gapped correctly and no need to use anti-seize with these plugs as they are supposed to have some kind of coating on the threads. A simple installation on the 3.8 v6. I should be good to go for another 135,000 miles. :)
