Stock for Stock I would bet the GN is faster.

Now you have the GN and then the GNX. GNX is the badazz mofo.

Comments: 1987 was the last year for the Regal and the Grand National, but Buick decided to go out with a bang (although the rear wheel drive G-body platform would last one more year until 1988). A whooping 26,555 Turbo Regals were sold, of which 20,193 were Grand Nationals. Buick made some changes to the powertrain and power increased to 245 bhp and 355 lb-ft. The grille was slightly revised, with the teeth set further apart and the Buick emblem siting on the left side. Chrome wheels also were new.

But the big news for 1987 was the introduction of the limited edition GNX. Only available for 1987, the Buick GNX represents the height of Grand National performance. In a nod to the famous Buick GSXs of 1970-1972, the GNX logo featured a larger "X" than the other letters, just like the GSX logo. All GNXs began life as fully optioned Grand Nationals that immediately left the factory and were sent to ASC/McLaren Specialty Products in order to be extensively modified. The modifications included a more efficient Garrett air-to-air intercooler and a special pipe that connected the intercooler to the engine coated with CERMATEL (Ceramic/aluminum) for increased heat rejection and heat disipation. Front fender vents were installed to pull heat away from the engine while driving. The GNX also received a special Garrett "hybrid" T-s turbocharger that used a very lightweight ceramic impeller (as opposed to metal in standard Grand Nationals). The decreased weight allows the turbo charger to spin up much faster, thereby decreasing the turbo lag time inherent in turbo charged engines. Maximum boost was set at 15 psi and the turbo used an electric wastegate. The turbo also incorporated special low drag, dynamic turbine shaft seals, and a built in contamination trap. All of these modifications added up to 275 bhp and a whooping 360 lb-ft. To handle this extra power, the transmission was beefed up with firmer shifts and the rear axle received a longitudinal torque ladder bar with a panhard rod to help prevent wheel hop and torque twist. It also received a special rear axle housing cover made of aluminum (with GNX embossed on it) that serves as an additional strengthening element and point for the torque bar. For even more strengthening, the car body received special structural reinforcements in the form of "behind the back seat bracing" and special chassis (steel cross member between the chassis rails) bracing. The GNX was the only Regal to ever receive 16 inch wheels. The wheels were made of a lightweight alloy and the rear wheels were wider than the front. The GNX came with P245/50VR16 tires in front and P255/50VR16 tires in the rear. Special welded in fender flares were added to the wheel wells to make room for the larger wheels and tires. The standard transmission was a reprogrammed Turbo Hydra-matic 200-4R four speed hooked up to a custom torque converter. Inside, the dash had a special Steward Warner analog gauge package. All GNXs were black in color and the only exterior identification was small "GNX" badges placed on the front radiator grille and rear deck lid. Under the hood, a special turbocharger heat shield had "GNX" stamped on it, similar to the aluminum rear axle cover. All GNXs received a special numbered plaque mounted on the passenger side dash which identified the number of that particular car (1-547). Also, the Fisher body plate has "GNX" stamped on it. Special "GNX" decals were used on the intercooler and other locations and there were several hidden I.D. stampings to prevent fakes. But all of this came at a price. The cost of the GNX option was a whopping $10,995, which resulted in a final MSRP of $29,900. All out performance doesn't come cheap.

Even more rare are the Buick Regal T-Type "Special T." These models had a Grand National exterior, but a Regal T-Type interior.

Production: Grand Nationals: 20,193 GNX: 547
Engines: Grand National: 3.8L V6 Turbo 245 bhp @ 4400 rpm, 355 ft-lb @ 2000 rpm. GNX: 3.8L V6 Turbo 276 bhp @ 4400 rpm, 360 ft-lb @ 3000 rpm.
Performance: Grand National: 1/4 mile in 14.23 seconds @ 98 mph. GNX: 0-60 in 5.5 seconds, 1/4 mile in 13.43 seconds @ 103 mph.

Stock for Stock I would bet the GN is faster.

YEP!

I have first hand experience at this speed contest.

I bought a brand new 1985 5.0 GT (last of the Holley 4 bbl V8s) 5 speed.
I would use it to beat the tar out of my college roommate's 1977 350 V8 Formula.
He got tired of this and when his Formula got T-boned, he used the insurance $$ to buy a brand new 1986 Buick GN.
We took both of them to the track on several occasions;

My GT ran 14.9s bone stock...His GN ran 14.4s bone stock.

I would get about 3 car lengths on him out of the hole then watch in my mirrors as he started to pull on me.....
by the top of second gear it was all over as he would walk by me in the GN.:o
When we were cruising side by side on the street, he learned to listen for my 5 speed shifter to click and knew that I was about to grab a gear on him,
so he was ready and had the hair-dryed V6 spooled up for me!:mad:

He eventually took it to Kenny Duttweiler for the full treatment...That GN was BAD!!!
NOBODY knew what it was back in '86...they'd ask how he got his 'Monte Carlo SS' to run so strong..

Now, If you ran a fuelie '87/'88 5.0 LX against a GN it would be a coin toss.

I don't need no stinkin' V-6!!:mad2:

Why on earth didn't GM put a 350 in that car???:cool:

ALL HOT RODS are s'pose to have V-8's....PERIOD!!!!:beer::bows:

Love the GN. I will own one before I die.

cheaper and easier to make more power than a 5.0???explain

Crank up the boost*, uncork the exhaust & dyno tune!

Cheap HP!

*Install a wastegate bleeder valve.

[Raudermaster]

Yea, stock for stock GN is faster. Kid I went to school with had a mint mildly modded (intake/exhaust) GNx, him along with 3 people in the car, including myself, toasted, I mean toasted a done up '87 SS Monte and a well modded '88 LX. We all know an LX is faster than a GT too since it's lighter.
