Default 05 GTO to get 400hp LS2....

Straight from GM
http://media.gm.com/division/2005_pr...gto/index.html

This is awesome news, new hood with functional hood scoops, bigger rim/brake package, and new rear facia for dual outlet exhaust. There will also be new badging with 6.0L under the GTO and two new color options.

Cool news, although it's pretty sad that GM's only budget performance vehicle is a ******* Grand Prix on steroids....

I'm not impressed. It's a 4000lb car with driver. 400hp is not going to solve the problem. It should put it in the 12.9 range, good but still doesn't stick with the competition. The sooner the GTO dies the better.

That handily outpowers "the competition", and it has an interior and assembly quality on par with all the foreign coupes in the same price range. Color me impressed.

The sooner more and better Holdens enter US showrooms, the better.

We can strip it down to svelt 3200-3500lbs. Last time I checked the GTO weighs in at 3700 and with the new LS2 it loses 15lbs from the engine alone, the LS2 is lighter than the LS1/6. Should make running down cobras that much easier.

Cobra= what 390hp S/C'ed and is a fat porker of a car
GTO= 400HP from a NA LS2 and is also a fat porker of a car, looks to be evenly matched, and don't pull "well chip the cobra and pulley it", cause i'll say spend the 600 on a N2O kit and play in the 10's all day long without working hard.

I gotta hand it to GM for listening to the consumer, and to having the ***** to put a 400hp LS2 in the Goat and not just the C6. They never did that for us F-body dudes, not even in the last year. They could slipped in a 405hp LS6 into a the last year Camaros and Formula's and T/A's

Agreed. The GTO is starting to look a little more tempting now with a better set of heads and intake off the factory. Who knows how well they respond to cam swaps. For the 4 seater luxury-type car.. I'm glad GM stepped up to the plate. GTO's look much tougher with ram air hoods. Who knows, the hood, exhaust, engine might all be lighter I have to say, I wasn't all that interested in the GTO last year, but that 400 horsepower sure is sounding good right about now. If I could sell my f-body and come out with a nice sized down payment next year, I believe I'd pick one up an throw some longtubes with stock exhaust and a cutout and a stealth cam in it Talk about powerful sleeper. Stangs wouldn't know what hit em.

Peace,
Josh

2005 PONTIAC GTO: THE NEW GOAT GETS MORE MUSCLE
GTO – the original muscle car – was re-introduced last year and returns with more power and style for 2005. A new LS2 6.0L V-8 engine replaces the LS1 5.7L engine, bringing with it an increase in horsepower and torque.

The ’05 GTO packs 400 horsepower (295 kw) – up from 350 horses (261 kw) – and 395 lb.-ft. of torque (546 Nm), up from 365 lb.-ft. (495 Nm). Transmission choices are the same as the ’04 model’s: The Hydra-Matic 4L60-E four-speed automatic is standard and the Tremec six-speed manual is optional. GTO’s more powerful engine should lower the 0-60 time to less than 5 seconds.

Enthusiasts will immediately spot the brawnier ’05 GTO, thanks to new badging and a revised rear fascia that incorporates a new dual-exhaust system – it splits the GTO’s two outlets, routing them to opposite sides of the rear fascia. The exhaust tips are polished for a more refined appearance.

Also available is a new hood design incorporating a pair of stylish air scoops. The scoops draw fresh air in to the GTO’s engine compartment.

The badges identifying the ’05 GTO’s bigger V-8 include a “6.0” badge on the trunk lid and revised “GTO” fender badges, which now incorporate “6.0 Litre” designations. The original 1964 GTO also wore “6.0 Litre” fender badges, but at a time when almost every other American manufacturer referenced engine size in cubic inches.

Along with the GTO’s power increase comes improved braking performance from larger brake rotors, calipers and pads. The calipers are painted red and the front calipers feature the GTO logo.

Additional changes to the ’05 GTO include two new colors (blue and grey), as well as driver foot rest. A line of regular production accessories (RPAs) based on the 2004 GTO Performance Plus SEMA concept vehicle is scheduled for start-of-production availability. The accessories include a tall rear spoiler, front and rear fascia extensions, rocker molding extensions and grille inserts. As part of GM’s RPA program, the accessories can be ordered and installed on the vehicle prior to delivery.

LS2 details

Compared to the Gen III-based LS1, the 2005 GTO’s LS2 V-8 incorporates several significant changes to help improve performance. The block is an all-new casting with cylinder bores measuring 4.00 inches (101.6 mm) in diameter. The cylinder heads and camshaft are revised, too, to deliver the airflow necessary to complement the engine’s larger displacement. Other changes include:

New aluminum block casting with revised oil galleries and provisions for external knock sensors – external sensors improve serviceability
Camshaft lift increased to take advantage of increased cylinder head flow
Camshaft sensor relocated from the rear of the block to the front of the block provides room for new oil galleries
Flat-top piston design with lower ring tension reduces friction
Piston floating wrist pins help quiet the engine
More efficient ignition coils require less energy to provide a comparable spark
Compression raised to 10.9:1
Larger, 90-mm single-blade throttle body
Reduced-mass water pump design with improved sealing capability
Engine “redline” raised to 6500 rpm
Revised and more powerful engine controller incorporates all electronic throttle control functions.
Balanced environment and safety
The new GTO is a contemporary performer. Its traits include impressive cornering abilities, a smooth ride and surprising comfort. The drivetrain rides on a 109.8-inch (279-cm) wheelbase, with a low stance that enhances the wide-track feel behind the wheel. The front track measures 61.4 inches (156 cm) and the rear track is 62.1 inches (158 cm) wide.

The fully independent suspension features MacPherson struts in front and a semi-trailing arm design in the rear, with specially tuned strut valving and spring rates. Direct-acting stabilizer bars and a variable ratio power steering system also are tuned to provide a sporty feel and increased driver feedback. Seventeen-inch alloy wheels and performance tires are matched to the performance-tuned suspension. Traction control and a limited slip differential also come standard.

The GTO’s premium interior is accented by a harmonious blend of details, complementing its dynamic driving experience. All-leather seating, as well as a leather-covered steering wheel and shifter ****, immediately conveys luxury, while items such as stainless steel sill plates, metallic-look steering wheel styling, satin nickel-look accent trim, and racing-inspired drilled metallic pedals add sportiness to the environment.

The front and rear sports seats are configured in a traditional 2+2 configuration, with side bolsters and the “GTO” name embroidered on the front seats. Interior seat and trim colors may be coordinated to the exterior color, with red, blue, purple and black interiors available. This splash of color extends from the seats to the door inserts to the lower part of the instrument panel to the gauge cluster.

Every GTO comes well equipped with a thoughtful package of interior amenities and safety features, including:

Air conditioning
Blaupunkt 200-watt audio system with six-disc in-dash CD changer and 10 speakers
Console with storage compartment, accessory power outlet and two cupholders
Cruise control
Rear defogger
Power door locks with lockout protection
Programmable keyless entry with laser-etched key for added security
Eight-way power adjustable driver and front passenger seats with power-assisted rear seat access feature
Tilting and telescoping adjustable steering wheel
Power windows with driver and passenger express-down feature
Daytime running lamps with automatic headlamp control
Theft and content deterrent system.
The integrated driver information center located below the instrument cluster includes readouts for average speed, average miles per gallon, trip odometer, trip time remaining, trip distance remaining, fuel used and instant fuel mileage. There’s even a stopwatch feature and a user-programmable overspeed alarm.

Safety belts remain the primary and most effective form of occupant protection. All seating positions in the 2005 GTO have three-point safety belts. Retractors for front outboard seating positions have built-in load limiters that allow a controlled amount of give in the belt, thereby reducing the peak load on the chest during the “ride down” in a crash.

Dual frontal air bags are standard and GTO is equipped with child seat anchors.

Would this be standard on a GTO or Judge..
The JUDGE could be OVER 400HP.
More than a C5,No way?

The press release states the LS2 will replace the LS1 as the standard engine. No word on a "Judge" option, I wouldn't hold your breath.
