The 2004 Dodge Neon SRT-4 is a high-performance sport compact car powered by a turbocharged 2.4-liter inline-four engine generating 230 horsepower and 250 lb-ft of torque, mated to a five-speed manual transmission. It achieves a 0 to 60 mph time of approximately 5.6 seconds and features heavily upgraded suspension, braking, and aerodynamic enhancements compared to the standard Dodge Neon.
Introduction and Historical Context
When Chrysler’s Performance Vehicle Operations (PVO) division—later renamed SRT (Street and Racing Technology)—unleashed the Dodge Neon SRT-4 for the 2003 model year and refined it for 2004, it fundamentally altered the landscape of American budget performance. While the base Dodge Neon was viewed as an economical commuter car, the SRT-4 transformed the platform into an aggressive, turbocharged street brawler capable of challenging far more expensive sports cars and imports.
The 2004 model year introduced critical updates that addressed early criticisms of the 2003 version, most notably the addition of a limited-slip differential and a power boost. Understanding the precise 2004 Dodge Neon SRT-4 specs requires looking beyond standard brochure numbers to examine the powertrain engineering, suspension geometry, interior features, and factory performance characteristics that made this compact sedan an enduring icon of early-2000s tuning culture.
Powertrain and Engine Specifications
At the heart of the 2004 Dodge Neon SRT-4 is a heavily modified version of Chrysler's 2.4-liter "EDV" four-cylinder engine. Unlike a standard naturally aspirated commuter block, the SRT-4 powerplant was engineered from the factory to handle forced induction reliably.
The engine block features cast-iron construction with oil-cooled pistons, heavy-duty connecting rods, and a robust crankshaft designed to withstand higher cylinder pressures. Sitting atop the block is an aluminum cylinder head featuring specialized sodium-filled exhaust valves to dissipate extreme combustion heat, alongside unique intake and exhaust camshaft profiles optimized for forced induction.
Boosting this engine is a water-cooled Mitsubishi TD04LR-16GK turbocharger integrated directly into the exhaust manifold. For the 2004 model year, Dodge increased factory boost pressure slightly and optimized the engine calibration, raising output figures from the previous year's 215 horsepower to a stout 230 horsepower at 5,300 rpm. Torque output remained an impressive 250 lb-ft, delivered across a broad flat band starting from 2,300 rpm all the way up to 3,600 rpm.

Transmission, Drivetrain, and Performance
Power is routed to the front wheels through a heavy-duty NVT350 five-speed manual transaxle. One of the most significant mechanical updates for the 2004 model year was the inclusion of a standard Quaife limited-slip differential (LSD). This mechanical torque-biasing differential dramatically improved traction under hard acceleration, virtually eliminating the aggressive torque steer and inside-wheel spin that plagued the open-differential 2003 models.
The transmission utilizes heavy-duty gear sets and stronger synchronizers to handle the high torque output. A Sachs-supplied high-clamp-load clutch assembly transfers power smoothly while enduring aggressive launches.

- 0–60 mph: ~5.6 seconds
- 1/4 Mile: ~13.9 to 14.2 seconds at approximately 100–102 mph
- Top Speed: 153 mph (electronically limited or aerodynamic drag-restricted)
- Braking 70–0 mph: ~170 feet
Chassis, Suspension, and Handling Dynamics
To harness the power of the turbocharged engine, PVO engineers reworked the standard Neon chassis. While the basic MacPherson strut front suspension and independent multi-link rear suspension layout remained, every spring, damper, bushing, and anti-roll bar was stiffened and retuned.
The vehicle sits lower than a standard Neon on stiffer coil springs paired with Tokico gas-charged dampers. The front anti-roll bar measures 24 mm, while the rear features an 18 mm solid bar, contributing to neutral handling balance with a minor, controllable amount of lift-off oversteer if provoked.
Steering is managed by a power-assisted rack-and-pinion system with a quicker ratio than standard Neons, offering direct feedback and responsive turn-in. However, the turning radius is notably wider due to the packaging constraints of the equal-length half-shafts used to mitigate torque steer.
Braking and Wheel Assembly
Stopping power on the 2004 Dodge Neon SRT-4 is robust for a compact car of its era, borrowing heavily from parts bins and heavy-duty testing regimens.
- Front Brakes: 11.0-inch (280 mm) vented discs clamped by dual-piston sliding calipers.
- Rear Brakes: 10.6-inch (270 mm) solid discs with single-piston calipers.
- Anti-Lock Braking System (ABS): Available as an option, though many base models were sold without ABS to satisfy purist demands.
The car rolls on distinctive 17 x 6.0-inch cast aluminum wheels finished in a silver hue. These wheels are wrapped in original factory specification 205/50R17 Michelin Pilot Sport unidirectional performance tires, providing strong dry grip that complemented the upgraded suspension tuning.
Exterior Styling and Aerodynamics
The exterior design of the SRT-4 serves a functional purpose, with every body modification contributing to high-speed stability, engine cooling, or downforce.
Up front, the fascia features large cooling ducts directed toward the front-mounted intercooler and brake assemblies. A deep front air dam reduces high-pressure air buildup underneath the vehicle. Along the sides, unique side skirts tie the front and rear fascias together while maintaining a lower visual profile.
The most prominent exterior feature is the rear decklid spoiler. Modeled after the units used in competitive racing, this tall wing generates functional rear downforce at highway speeds, improving high-speed stability. The rear bumper incorporates an integrated diffuser-style element and a cutout for the single, large-diameter polished exhaust tip coming from the stainless steel, muffler-less exhaust system (which relied on internal cat-back baffling and a catalytic converter for sound suppression).
Interior Amenities and Ergonomics
Inside the cabin, the SRT-4 balances economy-car roots with aggressive motorsport-inspired styling cues. The most notable interior components are the front bucket seats, heavily bolstered and designed by Shelby/Karsmakers. These seats feature deep side wings wrapped in two-tone cloth and vinyl, branded with embroidered SRT-4 logos, keeping occupants firmly planted during high-lateral-acceleration cornering.
The driver faces a leather-wrapped steering wheel and an instrument cluster featuring white-face gauges, including a 160-mph speedometer and a tachometer with a 6,250-rpm redline. Mounted prominently at eye level on the left side of the center console is a factory AutoMeter turbo boost gauge, allowing the driver to monitor turbocharger performance in real-time.
Standard interior features include power windows, keyless entry, and a CD stereo system. Amenities like a sunroof were intentionally omitted by the factory to save weight, lower the center of gravity, and preserve structural rigidity.

Frequently Asked Questions
What are the main differences between the 2003 and 2004 Dodge Neon SRT-4?
The 2004 model year introduced a factory power bump from 215 to 230 horsepower, a standard Quaife mechanical limited-slip differential for vastly improved traction, and revised fuel injectors alongside an updated engine management calibration. These changes transformed the drivability and launch capability compared to the open-differential 2003 variants.
Does the 2004 Dodge Neon SRT-4 come with a limited-slip differential?
Yes. Starting with the 2004 production run, Dodge made the Quaife torque-biasing limited-slip differential standard equipment. This addition significantly reduced wheel hop and torque steer, allowing the front tires to put power down efficiently out of tight corners.
What kind of fuel economy does the 2004 SRT-4 achieve?
EPA fuel economy ratings for the 2004 model hover around 22 mpg in city driving and 29 mpg on the highway. However, real-world fuel economy heavily depends on driving style; because the turbocharger activates under moderate to heavy throttle, aggressive driving will reduce fuel efficiency significantly. Premium unleaded gasoline (91 octane or higher) is strictly required to prevent engine knock due to the turbocharger's compression and boost characteristics.
Is the stock exhaust system muffled on the 2004 SRT-4?
The factory exhaust system is famously aggressive because it lacks a traditional rear muffler. It relies entirely on the catalytic converter and a secondary resonator to manage sound emissions. This design gives the car a deep, distinctive rumble at idle and a characteristic turbo-back pressure whistle, though it can produce drone at sustained highway cruising speeds.
How durable is the stock engine block for modifications?
The stock cast-iron block and internal rotating assembly are remarkably robust, often capable of handling up to roughly 350 to 400 horsepower on stock internals provided the fuel system and engine tune are properly managed. However, high-mileage examples require careful inspection of cooling components, head gaskets, and turbocharger shaft play before attempting any performance modifications.
Conclusion and Ownership Guidance
The 2004 Dodge Neon SRT-4 remains a landmark performance vehicle, combining accessible turbo power, sharp handling dynamics, and uncompromised attitude. When evaluating or maintaining a surviving example today, prioritize verifying the service history, checking for structural modifications or engine tuning abuse, and ensuring cooling and suspension components have been properly maintained. For enthusiasts seeking raw, mechanical analog performance from the sport compact era, the SRT-4 delivers an unmatched driving experience.
