1989 Trans Am 20th Anniversary V-6 turbo





Back in 1989, production sports cars were considerably slower compared to the fast, technology potent sports cars that are being produced today. Thanks to the shortage of fuel and the bad economy, the '80s were a breeding ground for poorly performing Mustangs, Camaros, Trans Ams and Corvettes. 

But in the late '80s, Buick brought some relief to the unimpressed gear heads with their 1986-'87 Grand National and Regal T-Type. The two very similar models where technically two-door sedans that came with a six-cylinder engine that used a turbocharger and an intercooler to produce 235-hp and some very impressive quarter-mile time slips. In fact, for those two years, the sluggish looking grocery-getters were the fastest American made production vehicles at the time.



Pontiac Looks to Buick for a Bad Ass 20th Anniversary Edition Trans Am
In 1989, Pontiac would prepare to celebrate the 20th anniversary of the beloved Trans Am. For the anniversary addition, Pontiac would go outside of the box and for the first time would produce a Trans Am with a V-6 motor, the same V-6 motor that Buick used for the dominating Grand National and Regal T-Type. For this special anniversary edition, Pontiac would produce 1,550 Turbo Trans Ams in different combinations of hard tops and t-tops, along with a leather or cloth interior option.

Pontiac did not offer a factory convertible Turbo Trans Am, but one was created for Jeff Beitzel the President of PAS, a custom car production company. The car is unique in that its origins were shared with other custom-made vehicles that PAS were involved with building such as the Syclone, the Typhoon, and the ASC-built GNX. The world's only rag-top Turbo Trans Am has changed hands several times and is presently owned by a wealthy Mexican oil baron who loves Pontiacs.

With Pontiac's 20 great years of Trans Am success, the Turbo Trans Am would be rewarded by being named the official pace car of the Indianapolis 500. 

So just what kind of performance stats can this Turbo Trans Am produce? You can expect 0-60 times of 4.6 seconds while stopping the ¼ mile clocks at an average of 13.4 seconds, and if you keep going with your foot on the gas, you will reach a top speed of 162 mph. But just like the Buicks, the possibilities of much faster times and better performance is completely feasible with affordable upgrades and the correct tuning.


Completing the 20th Anniversary Turbo Trans Am Package

To complete the package, the Turbo Trans Am would come with a 200-4R 4-speed transmission with a lock-up converter. Four-wheel disc brakes and dual piston aluminum calipers with vented rotors were also installed. The Trans Am suspension includes front MacPherson struts and a limited slip rear live axle with front and rear torque sway bars – meaning not only does it go fast in a straight line, but it also hugs the corners as good as any other American sports car.

The sticker price for this Turbo Trans Am was around $32,000. Nowadays, depending on condition and how many miles are racked up on one, you can find them for sale anywhere from $12,000-$45,000 give or take. This car is definitely an American classic and if you're lucky enough to own one, it would definitely be in your best interest to take care of it.

1966 Big Block Corvette: The First of Its Kind

Back in 1966, Chevrolet decided to get innovated and give the public something they have been craving – a small sports car with a huge motor. The Corvette was elected to take the upgrade that started a revolution of cars that would be labeled "Muscle Cars". Chevrolet created a feasible 427 cubic-inch motor for the Vette by taking the already powerful 396 cubic-inch motor that the Corvette was already using and machining the bore and stretching the stroke of the engine to a much larger 427 cubic-inches.

These 427 Corvette motors were available in two versions: the 390-hp L36 and 425-hp L72. Both engines were available choices given to consumers when ordering a Vette, and both engines performed sensationally depending on what kind of fun you were looking for. The lower output L36 motor would cost you about an extra $185.00, where the higher output L72 motor would set you back about $350.00.

The extra cost for the L72 would get you a better-structured motor that included four bolt mains, impact extruded aluminum pistons, a very aggressive camshaft, a Holly 780 CFM carburetor attached to an aluminum intake and a free-flowing exhaust. With the purchase of the L72, you would also get a K66 transistorized ignition to help complement the other higher output parts. Although the L72 was rated at a massive 425-hp, it was a well-known fact the actual horsepower output was well above that publicized rating. The reason for Chevrolet's deception on horsepower numbers was to avoid unwanted backlash from the safety legislation.



The big-block Chevrolet motors were a tight fit for the Corvette, and the power-to-weight ratio was very pleasing for speed freaks. Chevrolet would spend about six more years using a big-block powerplant with balls before going with low-output engines altogether. After 1972, the change to bring about more fuel-efficient cars would change what kind of powerplants all muscle cars would receive and would eventually spawn the end of an era, the "Muscle Car Era."

Small-block 350's de-tuned and ready to do poor performance was what the American car enthusiast would have to put up with for power through the 70's and 80's. In the early 90's, change for more power started up again and, since then, there hasn't been much reason to complain.

How Much Horsepower is Too Much Horsepower?


Anyone who has ever had an infatuation with power created by combustion engines will tell you, “you can never make enough horsepower”. But in this day-and-age where smaller engines and better technology takes us to astronomical performance levels, it seems like that thought process may not be so true anymore.


Normal-sized LS motors that already take in mass amounts of air and fuel by design leaves the car enthusiast with all kinds of options to upgrade other non-horsepower performance parts on their vehicle to perform better. A tubbed-out, roll cage-fitted vehicle with a massive supercharger sticking out of the hood may look fierce, but you might be surprised to watch a vehicle appearing to be mostly stock smoke the crap out of the wannabe race car.


When building a badass vehicle it should be more about taking the horsepower you plan on creating and making sure you can successfully get it to the wheels and then to the payment.



500 Horsepower Before 1990

Sure, 500-hp has been possible since guys started taking apart engines and putting them back together with the whole intent to go faster. But before the '90s, 500-hp in a daily cruiser in a 1980s Corvette, Camaro, Mustang, etc. just wasn't realistic. 


Not to say that 500-hp in a daily driver before 1990 has never happened, but for the most part, that kind of horsepower was reserved for track use, short drives to the car show, or for trailer queens. Driving back-and-forth to work every day or taking long drives would have been pretty unusual for 500+ horsepower vehicles in the late '80s, '70s, '60s, etc.


The New Age: Right Off The Showroom Floor Vehicles Are Plenty Fast With Plenty Of Horsepower 

Finding a sports car from this generation with over 300-hp is as easy as going to your local dealership. No upgrades needed, today's sports cars and muscle cars will leave any stock or upgraded '80s sports car trailing far behind. 


The new Corvettes, Camaros, Hellcats, Chargers, and Mustangs that we see today can easily make big horsepower and awesome 1/4-mile times. Even Cadillac and many other unexpected auto divisions have poured more horsepower into their vehicles than one could have ever imaged in the mid-'80s and early '90s. 


If you would have told me back in the '90s that there would be a six-cylinder Camaro in the 21 first century that would keep up with a '90s LT-1 Camaro and leave an '80s Z28 in its dust, I would have told you that you were crazy.


Well maybe not. 


My Dad was a Pro-Buick guy, so I attended many Buick events watching my Dad race as I was growing up. The early '90s is when we started to notice V6 Buick turbos pulling the wheels off the ground and turning in 10-second timeslips - that's when we knew technology was going to start to change. But we never even bother to argue the point with the Ford Mustang Fox-Body lovers, they wanted to hear nothing of the sort. Ha. Ha.



How Much Horsepower Is Too Much

It really all depends on what your ambitions are. Let's face it, if you want to go fast on a race track, you can make more power than a top fuel dragster, but that does not mean you're going to dominate anything. 


If you're doing it just for show, I think that's kind of silly, but to each his own. Sure, it's great to sit at the car show or the drag strip and say “yep, my baby puts out 1,200 ponies”. 


But when a brand new sports car pulls up next to you at the light –quiet and stock looking – and he takes off on you like a rocketship, and your loud, monster setup is gasping for mass amounts of air while standing still trying to find just a little bit of traction just seems kind of embarrassing.


How Much Horsepower Is Just Enough

It all depends on what you are planning on doing with your vehicle. The perfect amount of horsepower to me would be being able to use and have fun with every bit of horsepower that I paid for. Sure, have there been times where I have wanted more horsepower for some of my vehicles? Absolutely, but I also like to eat as well. 

Having an extra boatload of horsepower under my hood that I'll never use doesn't really seem worth it if my bank account is at zero. And on top of everything else, at one point or another, you're going to get curious and try to find out what your vehicle can do. If you find out that the car, you or both can't handle it, you might find yourself with a vehicle that is wrapped around a tree.
