    Stage II Street Sleeper - Grandpa's Buick has balls

    Of all the forms that a street-driven car can take, the sleeper look has to be the most fun. For us GM jockeys, it doesn't get any better than a nonchalant dusting of some fool with a monster tach and a stinkbug stance. Turbo Regals have owned the patent on this sneak-attack tomfoolery for 17 years, but over time the word got out--tangle with a hissing Buford and get owned. These days, the gospel of Flint is fresh in the minds of the conquered, and passing a force-fed V-6 off as a run-of-the-mill Regal is no easy task.

    But if there's one TR left on this planet that could take a Stang-banger's lunch money, it's Rob Raymer's '87 Limited. This proprietor of Charlestown, Indiana-based Quarter Mile Performance (no connection to the Jersey-based shop with the same name) struck understated gold when he ran across this Limited and stuffed it with Stage power.

    Imagine seeing this on the road: pounds of chrome trim and chrome mirrors--you would probably move over out of pity to let the old geezer head straight to his grave. And he would be comfy getting there with the power bench seat, air conditioning, and column shifter. Of course, 34-year-old Rob Raymer is no grandfather, and a closer look at the Limited's Stage II mill should prove that point. Rob thanks Brad Lay, Tim Eger, Harry Hruska, and Lonnie Diers for helping him create this reliable Staged streeter.


    Raymer purchased this well-kept T in 1999 from the president of the Buick club in Louisville, Kentucky. The bone-stock 1987 Limited was a truly special-order G-body, with a dark blue metallic exterior, miles of chrome trim, a bench seat with a column shift, aluminum bumper braces and brake drums with a factory posi unit--and chrome mirrors! Rob has been into turbo GMs since 1987 (he currently owns two Ts and his turboed '98 Z28), so performance parts began popping up on the Limited posthaste. The first mods included basic bolt-ons combined with a Precision Turbo & Engine PT51 turbo, 50-pound injectors, and a PTE front-mount intercooler. Initial forays down the quarter-mile resulted in high-11-second timeslips from the 100K Buick, and with Joe Lubrant's chip tweaks and a few fuel pressure changes, the low 11s were in sight. The 3.8 was later reincarnated with billet mains and center caps, a PT70-1 turbo and 75-pound injectors. A FAST fuel management system soon replaced the prom, and after Harry Hruska of PTE spent a few hours fine-tuning the boosted mill's manners, Raymer had himself a streetable rocket sled.

    This combo produced soft-launch times of 11.01 at 129 running through the mufflers, but during one of his frequent street escapades, the 3.8's torque twisted up a driveshaft. The fractured shaft did a ton of damage--even with a driveshaft loop it still broke his tranny in half and shoved the converter into the crank thrust, wiping out the bearings. That was all the convincing Raymer needed to take his T's performance up a notch, and he began the search for a Stage motor.

    A Buick 272-inch Stage II mill was found and purchased locally, and this assembled long-block fell into the hands of Dale Voyles of Launch1motorworks.com. Dale tore the motor down and found a solid block with a 4-inch bore, a strong 3.625-inch Buick Motorsport crank, good bearings, 6.5-inch Carrillo rods and thermal-coated JE pistons. The Champion heads were in good shape, so Raymer sent them out to Precision Turbo to be receiver-grooved for lock wires. Meanwhile, King bearings were used during reassembly, and Total Seal Gapless rings were called on to keep the boost pressure contained. Precision Turbo's 244 hydraulic roller cam was installed to actuate the GN1 heads' 1.94/1.60-inch Manley stainless steel valves; T&D's 1.65-ratio roller rockers do the pushin' atop the Chuck Kuhn-ported Champion castings.

    [​IMG]
    The 272-inch Buick Stage II is topped with hand-ported Champion GN1 aluminum heads, enhanced with a PT74 turbo and a PTE front-mount intercooler, and lubricated by a Duttweiler remote oiling system with a 7-quart aluminum oil pan. Harry Hruska's FAST tuning was used from the previous 3.8-liter mill, with only a few parameters being changed for the Stage motor's increased appetite for airflow. Raymer likes to see an 11 to 11.5 to 1 air/fuel ratio on the wide-band O2, 1650 to 1680 degrees on his EGT gauge, and 780 O2 millivolts on DirectScan. This combo is good for 30 pounds of boost all day long, but the 75-pound injectors are already maxed out. Rob's new SMC alcohol system and 95-pound Delphi injectors should cure that ailment.

    After the motor was assembled, Raymer turned to Precision Turbo & Engine to upgrade his turbo and wastegate. A PT74 4-bolt turbo with a Q-trim wheel and an HKS wastegate were decided upon; the 75-pound injectors were retained, and ATR's hotwired Double Pumper fuel pumps would keep 'em fed. Once those air molecules get sped up, cooled down, inhaled, and ignited, they are shot out of ATR's stock-replacement headers and through its 3-inch Pit Bull stainless exhaust system.

    This grocery getter now possessed a solid 9-second potential, and there are those who would prefer to toss the factory 200-4R in favor of a built 400. Mr. Raymer isn't one of them.

    "I worked with Lonnie Diers at Extreme Automatics in Cincinnati for my tranny," Raymer explains. "Lonny builds an amazing 200-4R; this one has a lot of Bruce Toelle billet parts, and it should take us to the low-9s with no trouble."

    An Art Carr 3500-stall converter sends power through a custom-made driveshaft to a near-stock posi rear end reinforced with only Moser axles, C-clip eliminators, and a TA cover.

    A Kirban 145-mph speedo, a triple pod with Auto Meter water, oil pressure, and boost gauges, and a Toshiba 2065 with a FAST fuel management system provide turbophile Rob Raymer with the Stage II's vital signs. The laptop mount is a police-issue holder that went in when Josh Clemons of Clemons Racing installed the roll bar, which features removable back and side sections.

    Rob performed only mild suspension work to his cruiser. The front stabilizer bar was removed and 90/10 Lakewood shocks were installed. Out back, Metco lower control arms with instant center brackets, Hal 12-way adjustable shocks, dual air bags, and an ATR rear sway bar were installed for the day of reckoning--the only question was, how much power would they have to take?

    A trip to Clemons Racing in New Albany, Indiana brought the answer. With the T strapped onto the Dynojet and the boost knob set for 25 pounds, the mildly tuned V-6 pumped out 718 horses and 730 lb.-ft. of torque--at a rich 10.2:1 air/fuel ratio! And the first trip to the track was just as impressive--right off the trailer, Rob's Buick hissed to a 10.35 at 134! Raymer immediately fine-tuned the FAST system and added Goodyear meats, and that's when a 9.95 at 140 astonished the competition.

    "Every time we go to the track with this T and sit in the lanes with the race cars with mountain motors and no mufflers, you can't believe the strange looks we get with the chrome trim and bench seat," Rob laughs. "This Buick is about as grandpa-looking as they come. But it's a little bit different when you come boilin' past those same cars at the eighth-mile."

    I'd rock it- debadged, painted jet black, with some 16x11 Drag Stars out back wearing some Drag Radials and dark-tinted windows so nobody can see into the cage/gauges. :o

    Actually that would be today.

    Buick had a vastly better lineup of cars at that time, each with a performance trim. The LeSabre became (and still is) the top selling fullsize car in the country, and in addition to the turbos V6s they had a turbo I-4, a hot DOHC, four valve per cylinder Skylark GS, and the Reatta coupe and convertible. The interiors were much nicer as well, in both materials and design.
