Mopar Performance Stage 1 Turbo Upgrade Kit
Mopar Performance has introduced a whiplash-inducing Stage 1 turbo upgrade kit. This kit pushes the power and performance of the 2.4-liter turbocharged engine in the 2003 Dodge SRT-4 to 240 horsepower and 260 lb.-ft. of torque, and the 2003 Chrysler PT Turbo to 235 horsepower and 260 lb.-ft. of torque.
The kit consists of four fuel injectors, which produce a 10 percent greater flow rate than stock injectors, and one Mopar Performance powertrain control module (PCM). The PCM has been calibrated for increased wide-open throttle and part-throttle boost, more aggressive exhaust note during deceleration, improved turbo response, enhanced first-gear boost schedule for a higher performance launch and a boost-hold feature during wide-open throttle shifts.
Manufacturers suggested retail price (MSRP) for the Stage 1 turbo upgrade kit for the 2003 Dodge SRT-4 and Chrysler PT Turbo manual (P5007862/P5007943) is $399. MSRP for the Stage 1 turbo upgrade kit for the 2003 Chrysler PT Turbo automatic (P5007944) is $429.
Stage 1 turbo upgrade kits for the 2004 Dodge SRT-4 (P4510592; $399), the 2004 PT Turbo manual (P4510606; $399) and 2004 PT automatic (P4510597; $429) are also available. (Stage 1 kits for the 2004 models result in the same performance ratings as the 2003 models: 240 horsepower and 260 lb.-ft. of torque for the SRT-4 and 235 horsepower and 260 lb.-ft. of torque for the PT Turbo.)
Mopar Performance Turbo Blow-Off Valve Conversion Kit
The new Mopar Performance turbo blow-off valve kit reduces intake air charge temperature by venting the hot compressed air to the atmosphere and not re-circulating it into the intake system. The blow-off valve kit is a must-have accessory that enhances the distinctive turbo sound of the Dodge SRT-4 and Chrysler PT Turbo. The kit (P4510548) is now available for the 2003 and 2004 Dodge SRT-4 and Chrysler PT Turbo for a MSRP of $69.
Mopar Performance Limited-Slip Differential (LSD)
Mopars limited-slip differential is another high-quality component that helps make the 2003 Dodge SRT-4 even quicker. The Quaife automatic torque-biasing (ATB) differential is available exclusively from Mopar. The unique design improves handling and steering, and powers both drive wheels under nearly all conditions. It senses which wheel has better grip and biases the power to that wheel. It does this smoothly and continuously, and without ever completely removing power from the other wheel.
Available later this year, MSRP for Mopars LSD (P5007923) is $1,369. Note: This LSD is standard equipment on the 2004 Dodge SRT-4. (An installation kit P4510588 is required when ordering this part.)
Mopar Coilover Suspension Kits
The Mopar coilover suspension kits are a result of a relationship between Mopar Performance and KW Suspensions. Utilizing DaimlerChrysler specifications to ensure optimum performance, the kits feature new stainless steel INOX technology exclusive to Mopar Performance. The Mopar coilover kits thread design and aluminum spring perches allow Dodge SRT-4 owners to easily adjust vehicle height. Additionally, the special thread shape and specific properties of the polished suspension struts ensure that virtually no corrosion occurs even after years of the strongest weather influences.
The basic Stage 1 suspension components include a set of higher rate drop springs (P4510458) that utilize production Dodge SRT-4 dampers and an anti-sway bar kit (P4510454). Both components will be available early next year.
The Stage 2 Mopar coilover suspension kit is an introductory coilover system height adjustable only. Its fixed-valve dampers are calibrated to provide a balance between comfortable road feel and sporty driving.
Stage 3 Mopar coilover suspension kits are height- and rebound-adjustable, and include up to 50 percent more adjustability than Stage 2 settings. This allows the driver to tune the SRT-4 suspension to even greater degrees, from a comfortable ride, to sporty, to stiff tailoring roa
