Sold my Cobra and stumbled upon a few things in the garage, prices don't include 3% paypal fee: -Stock double-blade throttle body, elbow, and eaton supercharger with upper pulley (I believe 2.8). All w/ 55k miles and perfect working order, replaced with a POSI ported s/c. SOLD -EGR rail and...

I am only the second owner of this '03 Cobra and have driven it for the last 20k miles of its life. It has been my DD for the past 2 1/2 years and has proven to be very reliable. Unfortunately, at 72,3xx miles a piston ring failed, causing excessive detonation. Since then, I had a Ford Racing...

I just decided to make a new thread to better advertise the car. I also lowered the price significantly to skip the negotiating process. Do you want to buy an 03-04 Cobra but afraid of what the previous owners might have done to it? Was the motor/tranny abused or suffered severe crashes covered...

Do you want to buy an 03-04 Cobra but afraid of what abuse the previous owners may have put it through? Look no further! This Cobra features a recently built (by ModMax) Boss 302 shortblock. The bigger bore helps to unshroud the 4 valves, resulting in better gains than a stroked 4.6L. I am the...

Without crowding the marketplace with another ridiculous "Feeler" thread I was wondering what to set my car at. I was thinking of asking between $21.5k-$23k. Local Cobras on autotrader are anywhere from 17.5-23.5 with convertibles and yellow cars towards the bottom. 2003 Ford Mustang Cobra -73k...

I was getting some work done to the car and had my 03 cobra tuned at the same place. Originally with a returnless system on my posi ported eaton at 17lbs I made 525/543. I was having an issue switching gears on wot runs where the car would hesitate, so I went with a return set-up. Same shop did...

My heads need a valve job, with two local options one of them is booked for 1-2 weeks and the other wants $1250 :bs: Anyone have any recommendations? I'm located in Fort Myers and I'd rather drive than ship the heads to keep costs down. Thanks

I'm trying to get a sense of how much the car is worth in the current market as it's not exactly like many others out there. I love my Cobra but being a college student pursuing a medical career, it's just not practical at the moment. I'll try to list as much information as possible 2003 Ford...

What is the best way to run these two tunes? Our city's ony pump is almost 30mins away so best I can do is fill up my tank some jugs then run 93 when I can't get over there. I'm worried that after a couple full tanks of 93, no matter how empty I try to get the volume down, there will still be 93...

Post up what you have for sale. Thanks

Finally put the order in for a Boss 5.0 short block and plan on holding on to my ported eaton, up the compression to 9-9.5:1 and running a 93 tune and e85 tune. Any other extra-CI. cobras out there running anything similar? I'm shooting for 600 :burnout:

Just like the title says, I'm looking for 80's as I may be running E85 in the near future. Or if anyone wants to buy my 60's or sell me your 80's, post here! Thanks Ross

Looking for some reputable companies to have an assembled shortblock delivered to my shop. Ive heard mixed reviews on MMR and their warranty claims. Livernois seems to be a solid company as well as modmax. I'm also interested in upgrading to the Boss 5.0 block... or possibly a stroked 4.6 to...

I apologize if this is a repost but its worth being shown again. If you have a thing for astronomy you will love the following video. It's concerning the electric model of the universe and in turn actually simplifies everything. For instance: -Everything wasn't created out of nothing... no...

What exactly are the pros/cons of running higher compression with a ported eaton? Obviously more power with more risk of detonation but I'd like a little more specific. I've tried searching but the search function is horrible on this forum, can't search "compression" or "supercharger". Thanks...

What about the bigger superchargers gives you more power? If my posi ported eaton spins at 17lbs, will a whipple at 17lbs be giving me the same amount of power? So the larger s/c just increases the window of acceptable rpms to spin the blower? Is this the same with turbos? Thanks

I made an earlier thread, titled weird. Car will be a DD, probably sticking with ported eaton with spray and moving up in the future. Would you go for a modular 4.6 or stroked to a 4.75 or 5.0? What would be the HP gains over stock? Higher compression? How about the lightning/navigator's 5.4...

During a run I seem to hurt my cobra, it's a teksid block, posi ported with a 4lb lower and supporting mods making 525/540. What gains should I expect if going to a 4.75 shortblock? What about the 5.0 mod stroker? What are the pros/cons of the 5.4 block? Also, what are the pros/cons of ported...

During wot runs on my 03 cobra, when I shift and continue to floor the pedal, the car falls on it's face. Most do the pprv delete but many say it depends on the tuner. My tuner has great customer service and has been trying to take care of the issue for a little while now. What can be done to...

I've been researching the issue but keep finding people with a delay at the top of their rpms. The issue I'm having happens during wot runs. Say a 2nd gear roll, slowly accelerate until wot and the car will pull hard as ever if i'm not spinning. Then i release throttle shift to 3rd and pound the...

Is it legal for me to record the traffic stop with my phone and use it later in court? Would I have to declare that I'm recording him or can I do it without his knowledge/consent? I feel this would help protect me and be valuable for my lawyer to have the actual conversation.

Last night I almost got into a head-on collision with a Ford Expedition K9-Unit and tonight in the same exact spot I almost rear-ended an officer in his crown-vic, both had no lights on the exterior or interior. Normally when an officer is trying to be "stealthy" they at least have the front two...

I'm running breathers right now and not too fond of vapor coming out of the hood vents or through the a/c vents so I bought an oil catch can. I'm wanting to do the passenger side, Question is: From the front of the passenger side valve cover, the tubing goes to the oil catch can, then from the...

Only recent mod done was a modified fpdm. After the install I noticed that while trying to pass traffic in 6th gear there was a slight studdering at 75% throttle. Since I usually dont put the car under heavy load in high gears I thought maybe the car always did that. Since then I've been toying...
