Jose Torres and his shop Jose's Motor Sports in Camden, New Jersey, is no stranger to Turbo Buicks, having built many a turbo V-6 since 1987. His most recent passion project, an '87 Grand National, has been coming together over the past eight years. The GN was purchased with the intention of transplanting a powerplant that would make good use of the rollcage and 4-link S&W Race Cars installed for the previous owner. To do so, Jose's put the boring bar and honing machine to work on a Buick Stage II off-center block for a bump in displacement and the strength to easily propel the full-weight GN into the nines and beyond. Using JE forged pistons and rings, Carrillo forged rods, and a Buick Motorsports forged crank, the short-block boasts 252 cubic inches. A 220/230-duration Comp Cams solid oller cam dishes up the extra spent fumes to a Precision Turbo P76 turbo, while also inhaling 25 psi of chilled boost from a PTE front-mount air-to-air intercooler. Champion aluminum heads were hand-blended and polished by Jose's crew prior to installing stout Manley 2.02 intake and 1.60 exhaust valves. The dished pistons and heads serve up a oost-friendly 8.0:1 compression that works well with 116-octane race gas to resist detonation. On the top end, T&D 1.6 ratio rocker arms and a Bowling Green Customs intake make sure the solid roller and Comp Cams pushrods' commands are well heeded. The Bowling Green intake is port-matched to the heads and mated with an Accufab 70mm throttle body as well as 96-pound injectors from Precision. A Weldon Racing external fuel pump supplies the estimated 800hp motor with adequate go-juice, while a FAST computer controls the injection and ignition from the stock coils and MSD DIS-4 box. A Lee's Performance wastegate and Keith Mease/MPE Racing Fabrication 3-inch downpipe vent the turbo's regurgitation. Three-inch pipes take the fumes the rest of the way, before terminating aft a Flowmaster muffler. ATR ceramiccoated headers, in addition to a transbrake- equipped Turbo 400 from Trans Specialties, help the turbo spool. Nearby Pat's Performance Converters supplied the 4000-stall, 9-inch torque converter that enabled a 1.30 60-foot time. The S&W Race Cars 4-link is also responsible for those impressive short times, boasting QA1 adjustable coilovers, fully welded track locator, adjustable shock mounts, and an integrated 9-inch rearend housing. Moser 35-spline axles and 4.30 gear accommodate the enormous 32x14 Mickey Thompson slicks. A lightweight spool and Weld wheels keep the rotating mass in check, while the simplicity of the stock interior and body panels (aside from the J&E Automotive cowl hood) keep the race weight at 3,360-pounds with driver. A chromemoly 10-point cage from S&W does help minimize the burden, as do Wilwood brakes, which are also very crucial to making the 9-second beast safe. As a frequenter of many Buick-vs.-Mustang events at Atco Raceway and Old Bridge Township Raceway Park, Jose has been certain to make sure his Buick is up to NHRA standards with an ATI balancer, 3-inch chrome-moly driveshaft, J.W. flexplate, ATR driveshaft safety loop, Gforce harnesses, and a battery cutoff. It's almost a sacrilege that this nearly Outlaw-style build plays by the rules, but it just goes to show that it doesn't take any trickery (nor does it take eight cylinders) to whoop on Mustangs.  A ported Bowling Green Customs...  A ported Bowling Green Customs intake, accufab 70mm throttle body, Champion ported aluminum heads, and Jose's motor Sports-built Stage II 252-cube V-6 gobble 25 psi from a pte p76. the estimated 800-horse V-6 mill hauls the 3,300-pound brick to consistent 9.4s at over 145 mph.  The big 'ol set of mickey...  The big 'ol set of mickey thompson slicks measure 32x14 and give the Gn that pro Street look, but with the power to back it up. the combination of big power, big tires, and a kick-ass S&W 4-link enable 1.30 short times launching around 4,000 rpm or 10 psi of boost.  Weld wheels and m/t skinnies...  Weld wheels and m/t skinnies make up the front rolling stock, also using Wilwood brakes to lighten the front-end load. the GnX louver fenders are an instant classic with the Dupont paint job.  The stock Gn interior is relatively...  The stock Gn interior is relatively unmolested, as a shift light, autometer gauges, S&W chromemoly cage, G-force harnesses, and a turbo action Cheetah shifter make up the essentials for the 9-second S&W-tubbed streetcar. | DATA FILE | | Car: | 1987 Grand National | | Owner: | Jose Torres | | Block: | Stage II, 252 cid | | Compression ratio: | 8.0:1 | | Heads: | Champion aluminum, ported and polished by Jose's Motor Sports, 2.02 intake, 1.60 exhaustvalves | | Cam: | Comp Cams, solid roller, 220/230 duration at .050, .560/.560-inch lift, 112LSA | | Pushrods: | Comp Cams hardened | | Rocker arms: | T&D 1.6 ratio | | Pistons: | JE forged | | Rings: | JE | | Crankshaft: | Buick Motorsports forged | | Rods: | Carrillo forged | | Throttle body: | Accufab 70mm | | Fuel injectors: | PTE 96 lb/hr | | Fuel pump: | Weldon Racing | | Ignition: | MSD box, stock coils | | Engine management: | FAST, tuned by J&M Motorsports | | Turbo: | PTE 76mm | | Boost: | 25 psi | | Intercooler: | PTE air-to-air | | Wastegate: | Lee's Performance | | Exhaust system: | ATR headers, MPE Racing Fabrication 3-inch downpipe, 3-inch exhaust, Flowmaster muffler | | Transmission: | TH400 by Trans Specialties | | Torque converter: | PPC 4000-stall, 9-inch non-lockup | | Driveshaft: | Chrome-moly 3-inch | | Front suspension: | Stock springs, control arms, swaybar, QA1 shocks | | Rear suspension: | S&W 4-link with QA1 coilovers | | Rearend: | S&W 9-inch, Moser 35-spline axles, 4.30 gear, spool | | Brakes: | Wilwood front and rear | | Wheels: | Weld 15x3 front, 15x14 rear | | Front tires: | M/T 26x3 ET Front | | Rear tires: | M/T 32x14 ET Drag | | Fuel octane: | 116 | | Race weight: | 3,360 lbs | | Best e.t. / mph: | 9.40 at 147 | | Best 60-ft. time: | 1.30 | | Current mileage: | 40,000 |

1999 Pontiac Firebird Trans Am - Street Heat
Almost no other GM model pulls off the aggressive look quite like the fourth-gen Trans Am, and when you modify one like Nathan Turjillo from Las Vegas has, well; you end up with a real showstopper....
