If you really knew what you were talking about, you wouldn't refer to it as "pozzie" instead of "posi", which is short for "posi-traction", the GM brand name for limited slip differentials.

I have owned a 1991 Ford Thunderbird Sport for almost a year now. The car is as awesome as my 1979 Thunderbird Heritage Edition. The car has been well cared for and the only problem I am having is with the headlights going off after a few minutes of running the car. The car as I have been told, by Ford Motor Company in Dearborn Michigan is in actuality indeed a 1991 Sport - and there were only a handful built as Ford's return with the thunderbird to NASCAR racing and as a tribute to Mark Martin. The Sport has a cloth interior and stripe on body side. Aluminum wheels and rear defrost. I know of about 12 of these cars and they all are in great shape due to the rarity of this car.

I just purchased a 91 Thunderbird. I have owned a lot of muscle cars, and this thing is crazy fun. It is the Sport package, it does bear all the sport features including the sunroof and the red stripe V8 badges and the 5.0 HO motor. Yes it does say Sport on the rear, and yes I love the car. And it was according to the VINs, which all match, built in march of 91, making it a true 91, not a 91 half.

Has anyone added a super chip to there 5.0 HO Thunderbird? Was it worth the money? I own a 91 Sport. I have installed a Flowmaster muffler kit and K&N filter. The latter did improve performance.

I got a 92 Sport, and I went up against my friend's 95 4.6 Sport 5 times in a row and I roasted him like a chest nut on Christmas day!

There is an aftermarket for the 4.6, but they're still far too expensive for my taste. For your average day to day guy with a limited budget, I recommend the 5.0, but if you're a pro racer with sponsors and an an unlimited budget, the 4.6 is a better choice due to their overall weight and rpm ranges. It just depends on who you are and what you're doing.

Very interesting. I live in Australia and have owned a 1991 Thunderbird sports for 12 years

I have admired the car since I saw one in the states and was lucky enough to find one over here. Your comments have confirmed some of my beliefs that they are unique and a great car, I get plenty of looks and people wanting to know what the hell is it.

Is there anybody out there who can give me a contact for parts in the states as you can imaging getting spares over here is impossible. Also the steering wheel is on the right hand side thanks to a inverted corvette steering rack and dash mods were lots of fun, not.

I have a 1991 Ford Thunderbird 5.0 HO.

The thing is a beast! Sadly it will be crushed when traded in on a newer vehicle this year. I will receive the $4500 "cash for clunker" and $500 trade in value. For this "deal" to go through the vehicle MUST be crushed. A sad day, as I've owned it since 1992.

It's great to hear all the great stories about keeping your cars in great shape.

"I will receive the $4500 "cash for clunker" and $500 trade in value."

Don't count your chickens before they are hatched. I read the program is only for pre 1984 cars because the goal is to reduce pollutants, not just increase overall MPG. Maybe that isn't totally right though. There were probably some last minute adjustments to the bill we haven't heard about yet since the bill just passed today.

I had a 91 T-bird Sport. The package, according to the sticker, was Sport package 434, part of the preferred equipment package 152. Now this is not listed as a package in the T-bird brochure, but I had the car and bought it in Aug of 91. Does anyone truly now about this car and how many were made, and how many are still out there? The last information I have on my old one was it was registered in South Jersey with about 134,000 miles on it. That was back in 2002. I would really love to find it and buy it back. I loved that car!

I have a 92 Thunderbird Sport. Had it since 99 and will not part with it.

I recently wrecked it and am going to have to replace rear quarter panel. While looking for a donor car, found another Sport, the guy says it's a 90 model Sport, did they even make a 90 model Sport?

It has now been a year since I bought my 91 Sport Thunderbird. I was pleasantly surprised when I got a call back from Ford Motor Company this past spring that put all my questions to rest.

As I expressed in earlier notes, the Sport option on the 91 T-bird is true, however not shown in the brochure. The Thunderbird's markings are obvious. Red clot. Black paint. Red body stripe. aluminum wheels and a cement pounding 5.0 H.O.

The folks at Ford were gracious enough to tell me all about the car. It is estimated at 250 hp at the rear tires. There were only 243 of these cars built in mid 1991. Mine was built in May 13th of 91, almost at the end of the run for the year.

As a lot of you have noticed, all the comments here deviate, but if you are serious about your T-Bird, I would strongly suggest you go to Ford's web page. In it you'll find a (contact us) icon. This will allow you to leave an e-mail in which you can put your Vehicle;s vin # and they'll get back with you. It was pretty cool of Ford to take the time to answer me, specially about this old of a car, but it was definitely worth the time to write the e-mail. Two days later I got the call.

I am now in the process of restoring the car, which won't need a lot to get finished since its previous owner took real good care of it, but I will need to redo the transmission for it is starting to slip when going into overdrive. It shifts really hard and it takes quite a while to go into OD. Good luck to all who have the luck to own one of these cool cars.

Hey bud, I've got a 1991 T-bird, also Sport. Didn't know it was that rare, never thought about it. My granddad was a Ford hot rodder and he left it to me when he died. He also left me a 1993 Lincoln Mark 8. Both are fun to drive and neither ones are stock. Thanks for the info.

Just came across these postings. Now I am kicking myself for trading my 1991 Thunderbird Sport in for a mini-van in 2005. I bought it new in Nov. 1991. It was a charcoal gray 5.0 with a red stripe. The suspension, transmission, and rear differential were unique to the Sport, and it was very much an upgrade over the base. That car outhandled Camaro and Corvettes that I owed. My Sport would run 0-60 in about 7 seconds, which was fast for the time. The Sport was a package produced mid way through 91 in an answer to complaints about a lack of an available V-8 when the car came out in 1989. It was a great car that I still miss.
