This Hellcat-Swapped Dodge Viper Costs Less Than a New Nissan Versa

Dodge Vipers are among the most visceral performance cars ever sold, especially the early examples that predate traction control, stability systems, and any real safety net. They were loud, crude, and built for fun. Yet, owners still love modifying them. Usually, that means more power, forced induction, or aero tweaks. However, this 2001 Viper RT/10 listed on Cars and Bids turns itself into a proper American muscle car. Its original V10 and manual transmission have been removed entirely, replaced by a supercharged Hellcat Redeye V8 and a three-speed automatic built with one goal in mind: going very fast in a straight line. We've seen some wild Hellcat swaps, but Throtl got real creative with this one – and it's selling for less than a Nissan Versa

Built For the Strip, Not the Street

Power comes from a 6.2-liter Hellcat crate engine, originally rated at 797 hp and 707 lb-ft of torque in factory form. This setup goes further, adding upgraded fueling, a smaller supercharger pulley, and extensive cooling upgrades. While no dyno sheet is provided, the seller claims the car runs the 1/8 mile in the high five to low six-second range. That performance explains the TH400 three-speed automatic, a transmission chosen for durability and consistency rather than driver involvement. The rest of the car follows the same logic. Penske Racing coilovers, drag-focused brakes, and lightweight wheels all support the car’s single-minded purpose. Exterior deletions like fog lights and windshield wipers reinforce that this Viper is not meant to be a street car. Much like obscure modified Challengers that end up as convertibles or a Hemi-swapped Jeep Renegade, this build exists because someone wanted to see if it could be done, not because it made practical sense.

When a Viper Has an Identity Crisis

In many ways, this car barely qualifies as a Viper anymore. It has 8 cylinders instead of 10, forced induction instead of natural aspiration, and an automatic transmission where a heavy clutch pedal once lived. Although its raw and unhinged character still lives on, it's a different type of crazy – one that's more serious and calculated. That cabin follows suit with a Sparco steering wheel and custom center console, but the execution is rough around the edges. It prioritizes function over finish, and it shows.

No Reserve Performance Bargain

With no reserve and bidding still under $20,000 with a day left on the auction, this Hellcat-swapped Viper is a fascinating proposition. It is not historically correct, not particularly refined, and not street-legal. If you're looking for something sensible, look away. This V8-swapped Viper is a one-of-a-kind drag machine, and that's all it is, and it costs less than the cheapest new car on sale. Whether you see it as sacrilege or brilliance is beside the point. Builds like this are why enthusiast car culture stays interesting.
