Jeff Dunham's "UltraViolet" 2012 Dodge Challenger SRT8 project--complete with 515-horsepower 426 HEMI.

2013 Dodge Viper

One of the many FIAT concepts at the Mopar booth.

This radical "Cafe Racer" Fiat features three-inch chopped top.

Mopar officials were joined on stage by comedian Jeff Dunham, but the company proved it’s not joking around about performance and customization options for its vehicles. Dunham was at Mopar’s SEMA press conference to unveil his custom 2012 Dodge Challenger SRT8 project vehicle and helped close out an eventful press conference which included new engine performance calibrations, a yoked-up 2013 SRT Viper, and new performance and customization parts for the Fiat. Here are the highlights:

  • Mopar will team up with Arrow Racing Engines and Arrington Engines to offer PCM-based engine performance calibrations for on-road, off-road, and racing applications. The calibrations will be available for select 2011-2013 vehicles.
  • The company will offer an emissions-compliant 5.7L HEMI crate engine for 1995 and older vehicles. It can be mated to automatic and manual transmissions and will not include the production multi-displacement system (MDS).
  • The newly created Mopar Off-Road Division and the Jeep brand will work together to create Jeep Performance Parts, which will offer high-end, hard-core Jeep parts — axles, lift kits, bumpers, winches, skid plates and suspension components, and more.
  • From its Jeep Performance Parts group, Mopar will offer a 6.4L and 5.7L V8 HEMI conversion kit for 2007-2011 Jeep Wranglers. The 6.4L engine kit, producing about 470 horsepower and 470 ft-lbs. of torque, will mate to W5A580 five-speed automatic transmissions and will soon mate with the six-speed manual. The 5.7L HEMI conversion kit for 2007-2011 Wranglers will produce about 375 horsepower and 400 ft.-lbs. of torque.
  • Mopar will offer more than 60 performance upgrades for its already potent 2013 SRT Viper, which begins production next month. Items available for the 640-horsepower coupe include a custom cat-back exhaust, cross car X-brace, carbon fiber coil-overs, and a variety of aesthetic upgrades.
  • The new Fiat Custom Shop will launch with 60 parts and will allow new owners to select custom parts for their Fiat at purchase.
