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.

smog pump eliminator I have a 94 Cobra 5.0l V8 and i am wondering how you plug off the connections of the hoses (where the hoses connect) and what if anything does this do to the sensors and or computer.I have already removed the catalytic converters,and do i need to get a smaller belt because 1 customer said the pulley is smaller than stock,are there complete instructions with this kit.


  • I have a '92 lx 5,0 that has BBK offroad-h pipe. Being an offroad-h pipe, it obviously doesn't have cats on it. i left the o2 sensors plugged into the h pipe, then removed the smog pump itself. i took the lines off then plugged the remaining parts of lines with a bolt, then clamped them. you can go to a local hardware store and get hard plastic hose plugs if you prefer. Then I installed the smog eliminator kit, which was simple. i didn't buy a new belt, i was able to run the stock belt. only reason should have to replace the belt, is if its worn out and/or dry-rotted . I just did this today......

I have a 91 GT. I was considering this, but would it be better to run a shorter belt?


If I buy this for my 89 mustang gt will I need to buy a smaller belt or is it the same width as the smog pump pulley?


  • Hello! The SR Performance Billet Smog Pump Eliminator will use the same width belt.

I recently received the smog pump eliminator, and after assembling the part it doesn't look exactly like the picture on this website. The metal shroud (piece connecting billet block and pully) gets thinner at the tip and doesn't fully go into the bearing, because of this it's hard but possible to get the pulley spinning level. The thinner area is shown nowhere on any pictures. Is it possible I've received a defective part?


  • Unfortunately, it sounds like you may have accidentally received an improperly machined product, we apologize. If you could please reach out to use via phone or email, we would be more than happy to assist you!

do I have to remove the convertors


  • No, you would not need to remove the catalytic converters to install the SR Performance Billet Smog Pump Eliminator.

Are there instructions in what to do? What holes are behind the heads? How big are the holes behind the heads? And what will I be able to use to cover them?


  • The SR Performance Billet Smog Pump Eliminator will eliminate the smog pump itself, you will need to remove the lines and then plug the heads. There are a number of ways that this could be done, including thermactor plugs, Welding the tubes shut, or installing a plug into the fitting where it used to attach to the smog pump. Thermactor plugs will give the cleanest looking install.

    Works great

    I bought this smog pump eliminator because the bearings in my pump were shot and a new smog pump would cost more $ to replace and would just be extra weight and draw more power. This eliminator is not only lighter by about 7 pounds but also provides more HP because it just a free turning pulley. Install was simple; just take out the smog pump and bolt this right back up. Very pleased, looks nice as well.

    Smog pump delete!

    Having the smog pump in your car is useless especially if your looking for power. With this you can get rid of weight and stress on the engine. Frees up a few ponies too. Looks good under the hood as well. What else can u want. Worth getting if you want to squeeze out 10-15 hp with a set of pullies as well.

    Decent but not perfect

    Although a nice part it does not bolt in without minor modification. Part of the block has to be filed down in order for it to bolt into place. Other than that it's a nice piece.

    Go with shorter belt !

    My Fordstroker 347 made it a boat anchor in about 8 hrs. Wore out 2 belts before I replaced with short belt. Pulley bearing was sloppy in pulley when it was new. Put on short belt and no more problems!

    This delete looks awesome but is completely pointless. For what you get charged for a single free spinning pulley you're better off eliminating the smog pump and spending an eighth of the money on simply a shorter belt and putting NOTHING THERE...this is an unnecessary shiny ad on. Take the pump off and but a shorter belt duh.

    Perfect if doing head and intake swap.

    The product was perfect quality upon arrival. I had to shave the corner on one side to get it to line up with the '95 gt stock bolt holes, after that, awesome fit. The pulley works amazing with no sqeaks, squeals, or wobbles. This is a must have if you are doing a head and intake swap, it is so much easier to just junk the smog system. Deleting the smog pump itself will not throw a check engine light. Also remember you have to plug the smog tube coming off the mid pipe.

    the product has good features

    I liked the added horsepower but they need to improve it,first the pulley is 1/2 inch smaller than the stock smog pulley which requires you to get a smaller fan belt,second the aluminum block requires grinding off for the bolts to align in the bracket,third there are no instructions and no plugs for the 2 1/8 inch vaccum lines or no plugs for the 2 3/4 inch big vaccum lines.Overall its a good product but it could definitely use some of these improvements I have listed.Scott Kozal

    Custom fit pulley

    When the box arrived it was open and had no packing slip or install instructions but all the parts were there. Assembly was not difficult, just a few minutes and the vice. When i went to install the part it wouldn't fit because the lower part of the aluminum block is square and wont sit low enough to properly put the bolt in without crossthreading, lucky i work at a metalshop and was easily able to chamfer the ends of the block 1/4", after that set back i easily installed the part. So far I've put 250 miles on my car and it still runs whisper quiet. .

    Loose Some Weight

    I bought this because I read stories of people having issues with belt slip by simply removing the smog pump and rerouting the belt with a shorter belt. Buy this if you want to avoid that problem, or the possibility of having that problem. The install for this piece is simple, but you do have to grind down one of the corners to get it to fit properly. The hardest part of the install is removing all the piping that goes to the heads and stock h-pipe. However, you can technically leave all this piping in and just plug up the holes. I'd personally do it right and remove all the dead weight. An added bonus to removing all this garbage... you get great access to the passenger side spark plugs, and header bolts.
