Up for sale is my 2003 Cobra. It just turned 15k miles and was bone stock until 8 months ago when I purchased it off my uncle with 12k miles on it. The car is in perfect working condition and the paint is in great shape...it has never been in an accident. I will list a few pics of the car when I...

There have been so many negative threads about their services I figured I would get the truth. This thread is open to anyone who has actually had their blowers ported with Stieg. If the Mods would clear the thread of any opinions or heresay I would appreciate it. I'll start the format...

So to make a long story short... The last 2 cars I've owned were Evo's, I had a '04 Evo RS and a '06 Evo IX. Both of the cars ran great and it seemed like I would win most of my races against other cars. Well, after having a motor issue with the Evo 9 I decided it was time to upgrade to a '03...

On Monday we are heading to SGS Performance and getting my '03 Cobra and my buddies '02 Harley truck tuned/dyno'd on their DynoJet. I was just wondering if their were any downsides to getting my car tuned when it's cold out and also what kind of #'s we should expect out of our rides. I am hoping...

I am from central WV and I am curious which tuning shops you guys would recommend within 5 hours from me. I'm not looking for the highest reading dyno...I would actually prefer a Mustang dyno. Either way, I want a good tuner with a nice quality dynotune. I have been referred to SGS Performance...

I have a ported blower with a 2.93/4# combo and the basic power/supporting mods including 63lb injectors and MAF. If you were going to buy a nitrous kit and money wasn't an issue which one would you choose and why? I am not wanting anything crazy right now, just a 50 shot. I want the best and...

I have a stock Eaton supercharger off my '03 Cobra for sale. It just turned 14k miles and its in great condition. The blower was completely stock until 1200 miles ago when I put a Billetflow hub and pulley. If you purchase the blower I will include your choice of a Red 2.76 or a Polished 2.93...

I have a used black JLT CAI that has only been installed in my '03 Cobra since July. The filter and all the parts are in great condition. The black tube has scratches on it from rubbing the hole through the fender.(typical) I don't think there is any visible damage while it's on the car...

I know there are probably a lot of threads on this topic but I havent seen anything as specific as I need. I am running the typical bolt-ons with a Steggy Stg V blower. People recommend that I run a 2.93 upper and a 4# lower. Are there any downsides with changing my lower pulley and also what...

As the title reads, I am looking to purchase a few parts for my '03 Cobra. All the parts must be in great shape and perfect working condition. I am looking for a 40A KB BAP, SCT MAF, JLT RAI (or something equivalent), Lower 4# pulley kits, 60# injectors, and possibly a nice Heat Exchanger. PM me...

I have seen a few guys on here running over 600whp/700tq on the streets. The last few cars that ive had have been AWD and im just curious as to what kind of wheel/tire sizes and IRS mods need to be done to hook from a 35-40 roll. I have seen people that seem to hook from a slower roll and im...

Well, I spent about 3 days looking for the best price on tires and after calling the companies that I normally deal with for my parts, I couldnt get any of them to come close to the deal that I got on a pair of Nitto 555 D/R's. The funny thing is, they already had the lowest price around and...

Well my name is Stephen and Im from WV. My last two vehicles were a '04 Evo RS and a '06 Evo IX. I just purchased a 2003 Cobra from my uncle and it has 12k miles and its black. I like it a lot but it takes a little getting used to coming from AWD power. You actually have to drive these cars and...
