Well I have a 91 ford thunder bird and it's great I am running about 16'sec 1/4 mile. it's stock and I beat a Honada accord (91) and a 98 dodge neon. I want to add headers and the manifold. oh also intake, chip, and a shift kit. with that I surely beat more cars.

I have a 1991 T-bird sport. Great car it has 90000 miles now.

It had 79000 when I got it last Nov. It has the 5.0 H.O.

Is white in color, light blue inside. I bought it for my daily drive to Denver from Colorado Springs. Great hi way cruiser 23 to 24 mpg and great passing power. I have been trying to get more info on the 1991 sport model and production figures.

My 1991 Thunderbird Sport does have limited slip differential contrary to the codes on the door label. I was loading it onto a trailer and forced both wheels to grab on pavement (transporting car only). I found the Ford build specifications on the internet for the 91 t-bird and it shows that "sport" was a package option and limited slip was standard.

My wife has been saying for the last 2 years that I should sell my 91 Sport, because the a/c stopped working. But now that she knows that only 500 were made that year, she has changed her tune.

Now did anyone else here have their a/c fail and what did you do to fix it? I have had everything to do with the a/c replace and it still leaks.

I recently had the A/C system rebuilt. My compressor locked up and contaminated the system. The only component not replaced was the condenser. If you replace the evaporator you should definitely replace the heater core. They tend to leak every five years or so. On the last heater core replacement I used a ground wire to ground the core. It's an actual bulletin put out by Ford. Hope it last longer than five years. I did not do it myself. The whole dash and panel must be removed to get to the core/evaporator housing. It was 650 dollars just in labor. The mechanic did a good job though. The A/C works better than ever.

I have a 1993 Ford Thunderbird Sport. It's a true Sport. 5.0 HO, White with Blue interior. I know they where made in 1991 and 1992, but mine is a 1993. I never seen another one. Everyone asks me why it says Sport, but I bought the car that way. Its in mint condtion, even though it has 202,000 miles on it. Very Fast, very comfortable. However is it Rare? If anyone could give me some information about a 1993 Thunderbird Sport model, it would be most appreciated . Thank you... Peace.

I have a 1991 t-bird sport, I love this car, will never get rid of it. it's red with moon roof and black stripe. It now has 150,000 miles and still runs great.

I have a 96 LX, great car. Recently installed full dual exhaust with a high flow x pipe. Lined up to go in it are 4.10s and a lengthened aluminum drive shaft out of an Interceptor. (T-birds have a longer driveshaft than a Crown Vic?! What?) It's true. By two inches.

In regards to what makes a T-bird Sport a Sport, brake rotors are another difference. The rotors are bigger, not sure how much bigger, but the guy at Napa asked he I needed the sport brakes or the smaller ones.

To add to the general statements being made in regards to 4.6 vs 5.0, when a lot of these statements were made, there wasn't a lot of mods for the modulars, but with this being one slow forum, now there are quite a few places a person can get heads, cams, stud girdles, intake manifolds, and much of the like.

The trans they bolt to the back of a 4.6 is designed to easily withstand 700lbs of torque. The blocks live happily with 600 horses. How long was the 302 around until the huge aftermarket surge to build those things up? 20 years? Lets see 64 is when the stang came out with a some kind of small block of similar design, performance five o stuff happened in the mid 80s. 20 years after 96 when it was first put in Mustangs as a performance engine puts the mod scene for these things around 2016.

Don't be so fast to accuse them of being weak and slow yet.. They just still need to grow up.

I have owned a 91 Thunderbird Sport since new! Purchased it in Aug. 91. Color is Twilight Blue with Titanium interior. All 91 "Sports" are identified by the Sport badge at the left lower tail light, V8 badging on both fenders and complete RED body trim molding on any body color available for this year model!

Information I have received over the years on production of the 91 Thunderbird with the Sport Option is 2976. This amount is less than the 90 35th. Anniversary SC Edition which was 3300+.

I feel this model will be very collectable in the next 10+ years!!

Sport Models have SC springs too.

I have a 1991 Sport and have been building it up. I am the original owner. The larger, lower Sport springs significantly lower the car's center of gravity, and therefore allow much higher speeds through curves and turns. The handling properties of any vehicle are a MAJOR advantage, regardless of street or strip. Horsepower and handling are what makes sports cars have higher initial prices and higher resale values. Transmission experts in my area told me that the shift points in the valve body are also different in the Sport Model, making the car accelerate better. The number of vehicles produced has a direct affect on the fair market value. This should make the 1991 V8 Sport have a higher appraisal value. However, any unkept condition can negate this. Anyone with a 1991 V8 Sport Bird should never be apprehensive about investing money to keep it in excellent condition. The huge aftermarket for the Ford 302 drive train also helps to raise the market value and marketability.

I have more info on the 1991 Sport. This should clear up some confusion on the model. Go to http://www.cardomain.com/ride/576934/1989-lincoln-mark-vii/page-6 and scroll down. There are some interesting facts about this vehicle.

Unfortunately you are all wrong in a lot of ways.

I am currently working with Ford and I have been for the last 20 years. I had a lot to do with the design of the 5.0 high output. What you don't know about it is that this engine actually is pushing out 246 hp stock, contrary to what is believed. I also know that the Sport model in 91 is a real car, and is a lot more rare than 500. There were actually 243 Sports made, and 50 Special Edition Sport models made in 1991.

This truly is a reliable car, and the engine is well capable of handling 800 hp if you have $25000 to invest in this beast of an engine.

It gets 28 mpg not 24, and it has a redesigned chassis for a smoother ride, and came with a lot more juice than the 4.6 ltr. The 4.6 was a guppie and was only used to improve fuel economy in the Tbird.

I'm sorry to burst your bubbles.

The rear diff is a 3:10 limited slip, and it's been in them since 88, and is almost a pozzie track system.

The a/c unit usually falls apart when the engine is idling for long periods of its life, because the engine is designed to drive at 140 mph, not 65 like the posted limit, which means the A/C unit bearings usually don't get lubricated enough to fully turn.

I bought my first Tbird back in the 70s when it came with the 5.8 ltr, the 351 Windsor; it is by far the best motor that was used to power the car.

I own 14 ford Thunderbirds and over 90 Ford vehicles; just to let you people know I am quite a genius when it comes to this car, as I am an enthusiast of it.

The 351 stopped being put in this car in 88 when I helped design the 302 for this car. I honestly think it was a mistake to stop putting the 351 in them, as it churned out a whopping 326 hp stock in the hi output edition that is mostly used for vehicles such as the 1995 Ford F150. Also the 351 Windsor is just a down sized 429 Cobra jet with a shorter stroke, smaller heads and a lower compression ratio, and the 302 was a downsized 351 so on and so forth.

The Tbird is truly a sports car, and should not be underestimated in any circumstance.

I also know for a fact that the 1991 Ford Thunderbird will beat a stock 1999 SVT Cobra, or I should say an SVT Mustang, which really has less torque unless you bring up the crank and cam size, which is very expensive on the SVT models.

If you have any further questions about this car, e mail me at colinljc@hotmail.com and I will give you an honest thought about what can go wrong with this car, what it is capable of, and what problems usually occur. This is not a joke in the slightest; I know what I am talking about.
