If you are looking to buy a Hellcat engine for sale you should know that this is a deal. A used 6.2L supercharged HEMI is a lot of money. If you make a mistake it can cost you even more. You have to think about the type of Hellcat engine you need if the mileage is correct and if the engine is in condition.

This guide will help you with all of that. We will tell you what to check, which type of Hellcat engine’s best for you and what questions to ask the seller.

What is a Hellcat engine?

A Hellcat engine is a 6.2L supercharged V8 made by Chrysler on the HEMI platform. Dodge started using it in 2015 in the Challenger SRT Hellcat and Charger SRT Hellcat. It makes 707 horsepower, which’s a lot.

The engine has a supercharger that pushes air into the engine, which makes it more powerful. The block is made of cast iron, which’s strong and the cylinder heads are made of aluminum.

If you want to replace your engine or put an one in a different car the Hellcat is a good choice. It is a supercharged V8 and it comes with everything you need from the factory.

Which cars use the 6.2L Hellcat engine?

The 6.2L supercharged HEMI is used in cars, including the Challenger SRT Hellcat, Charger SRT Hellcat, Challenger SRT Hellcat Redeye, Charger SRT Hellcat Redeye, Challenger SRT Super Stock, Durango SRT Hellcat and Ram 1500 TRX.

Each of these cars has a version of the Hellcat engine so you need to know which one you are buying.

Are all used Hellcat engines the same?

No they are not. The standard Hellcat, the Redeye, the Super Stock and the TRX are all different. If you treat them like they are the same you can have problems with your car.

Here is what makes them different:

• The standard Hellcat has a supercharger and makes 707 horsepower.
• The Redeye has a supercharger and makes 797 horsepower.
• The Super Stock has the supercharger as the Redeye but it makes 807 horsepower.
• The TRX has a calibration for trucks and makes 702 horsepower.

What to check before buying a Hellcat engine?

If you want to buy a Hellcat engine you need to check a few things.

First you need to know where the engine came from. The seller should give you the VIN of the car it came from.

Then you need to check the mileage. The seller should have documentation to prove the mileage.

You also need to ask about compression testing. This will tell you if the engine is in condition.

Check for any leaks, like oil or coolant leaks.

Finally inspect the supercharger and accessories.

Standard Hellcat vs Redeye vs Super Stock vs TRX

We already talked about the differences between these engines.. It is important to remember that you need to match the engine to your car. If you are replacing an engine you need to get the type. If you are putting an engine in a different car you need to make sure it will work.

Used Hellcat engine vs crate engine

You can buy a Hellcat engine or a new crate engine. A new crate engine comes with a warranty. It is more expensive. A used Hellcat engine is cheaper. You need to make sure it is in good condition.

Will a used Hellcat engine fit my car?

If you are replacing an engine, in the car it should fit.. If you are putting a new engine in a different car it can be more complicated. You need to make sure the engine will work with your transmission, fuel system and computer.

You need to think about the bellhousing, fuel system and ECU. The Hellcat engine needs a transmission and fuel system and the computer needs to be programmed to work with the engine.

When you buy a Hellcat engine you need to make sure the engine mounts will work with your chassis. The mounts that come from the factory will work if you are using the engine in a factory application.. If you are swapping the engine into a different vehicle you will need to get fabricated or aftermarket motor mounts.

The cooling system is also important. The Hellcat engine has two cooling systems, one for the engine and one for the supercharger intercooler. You need to make sure you have cooling system capacity for both.

These things are not impossible to deal with. You need to plan ahead before the engine arrives. Do not wait until after the engine is installed to think about these things.

What comes with a Hellcat engine? This can vary a lot depending on the seller. Before you buy you need to confirm in writing what is included in the engine package.

Most of the time a used Hellcat engine will come with the long block assembly, including the block, heads, valvetrain and timing components. It will also come with the supercharger assembly, intake manifold, fuel rails and injectors valve covers, oil pan, cover and timing cover. The engine sensors that were on the donor vehicle will also be included.

Sometimes you can also get the engine wiring harness, PCM or ECU accessory drive components, oil cooler and exhaust manifolds.. You need to ask about these things specifically.

When you buy a Hellcat engine you should expect a 6-month warranty against internal mechanical defects. This warranty should cover problems that’re present when you buy the engine, not problems that happen because of installation errors or other issues.

You need to read the warranty terms and understand what is covered and what is not. If the seller is not willing to discuss the warranty terms with you that is a sign.

The price of a Hellcat engine can vary a lot depending on the mileage variant and included components. If the engine has mileage and is a Redeye or Super Stock variant it will be more expensive. If it comes with a lot of components that will also increase the price.

To get a deal you need to contact the seller directly and ask about the mileage included components, inspection documentation and warranty terms. Do not just compare prices without getting all the details.

Here is a checklist of things to do before you buy a Hellcat engine:

• Confirm the donor vehicle with VIN documentation
• Verify the mileage from the donor vehicle records
• Get the results of a compression test
• Check the oil condition for metal contamination
• Inspect the coolant passages for oil contamination
• Check the supercharger for shaft play and housing condition
• Inspect the supercharger inlet for debris ingestion evidence
• Confirm that there are no leaks
• Verify the variant and component list in writing
• Review the warranty terms before you buy
• Confirm compatibility with your transmission
• Plan your ECU solution before the engine arrives
• Confirm fuel system compatibility

Some people have questions about used Hellcat engines. What is the difference between a Hellcat and a Redeye engine? The standard Hellcat produces 707 horsepower while the Redeye produces 797 horsepower. They are not directly interchangeable without fuel system and calibration changes.

Can you put a Hellcat engine in any vehicle? The Hellcat will fit in applications but it is not a simple drop-in. You need to address the transmission bellhousing, fuel system, ECU, motor mounts and cooling system before the engine will operate correctly.

How many miles is too many on a Hellcat engine? There is no mileage cutoff but documented mileage is important. A verified 60,000-mile Hellcat from a maintained donor vehicle is a better purchase than an unverified 30,000-mile claim with no documentation.

Does a used Hellcat engine include the supercharger? It depends on the listing. You need to confirm what is included before you buy.

What transmission works with a Hellcat engine? The factory pairings are the TorqueFlite 8HP90 eight-speed and the Tremec TR-6060 six-speed manual. For swap applications you need to confirm bellhousing compatibility and flexplate or flywheel specification.

Why does the PCM matter on a Hellcat engine? The factory PCM is VIN-locked to the vehicle. For a replacement in the same car you can reuse the existing PCM with a reflash to the replacement engine. For swap applications a standalone engine management solution is the common approach.

Is rod bearing replacement recommended on a Hellcat? Many experienced installers recommend replacing rod bearings at the time of installation on engines from higher-mileage or track-driven donor vehicles.

If you want to buy a Hellcat engine you need to be careful. The mistakes that can turn a deal into an expensive one are almost always avoidable. Buying from a seller who cannot produce donor vehicle documentation accepting mileage claims without verification skipping the compression test conversation and assuming variants are interchangeable are the four decisions that cause the problems.

You should work through the checklist above before committing to any purchase. Ask the questions before the money changes hands. A seller who pushes back on documentation and inspection details is a seller walking away from.
