Now looking at a mid 2025ish R/T and want to add a turbo.

2023 was the end of the Challenger R/T 5.7L HEMI.

Very few have actually Turbo'd the 5.7L HEMI, many of us can tell you about supercharging or procharging them.

I found 1 for a bit over $2200 but also know will need to upgrade injectors and such.

That is extremely cheap maybe a China Knockoff, I suggest you plan on way more money than that.

2022 Go mango widebody scat pack.

Since you had 2022 Scat, I would think you would be after at least that much power from the 5.7?

The cost of a turbocharger kit can range from $2,649 to $14,995 depending on the specific components and brand. Additionally, professional installation can add another $1,000 to $3,000.

You have to add to each kit to reach the HP level you are after it is not really the price you start with but you may get out that cheap, but it won't give you the performance you are after.

Now if you really want turbos and to get serious, start here.

2006-2023 Hemi 5.7L / 6.1L / 6.4L Street Sleeper for Challenger / Charger / 300C / Magnum Twin Turbo Kit by Hellion Turbo

 

Yep No 2025 R/T's 2023 was the last year of the Challengers. Also the Charger if they do go production with the ICE engine will be a Dual Turbo Inline 6 Cyl called the Hurricane.
Right now those Engines are having a ton of issues.

 

fat finger typing, meant 2015 or close to that

 

That makes a lot more sense!

Are you 100% after Turbos because a top mounted supercharger is something you can do yourself with their kits, they give instant power no spool up or waiting for the power to come in?

 

How does a stock auto and then a manual handle the increased power, also the rear end? Other items needing upgradess?

Supporting Mods:

Usually unless ordered from the factory with an LSD the 5.7 automatic transmissions come with a 3.07 open differential, that you would need to swap out to a 3.09 Limited Slip Differential which is great for the A8. $1,500.00 + or -

Also the rear negative Camber would need some correction so the rear tires will lay flat to the road, or you'll just burn up the insides of the tires spinning with only partial traction. Cheapest solution corrective press in bushings. $300.00 + or -

The next issue will be the OEM driveshaft center support failure that is more common now than ever, you can completely eliminate that issue by going to a 4" Aluminum one piece driveshaft. $1,200.00 + or -

Plus most 2015 R/Ts came with 8" wide rims if that is the case you'd need at least 10" wide to be able to run a 275 rear tire preferably MT ET Street S/S 275/40/20. $2,000.00 + or -

None of those prices include labor.

Whether Turbos or Supercharger without those supporting mods you'll just sit on the line burning up the wheels when you throw the power to it, but if you want to continue what Dodge has advertised just burning up tires emerging from clouds of smoke you'll be good to go without the supporting mods.

But if you want to get off the line with as little spin as possible you'll need the supporting mods.

 

Reason id not touch Turbos there is a ton of Plumbing needed, adding an Intercooler, and it blocks a lot of Air coming in and around the Engine.
Next the Lag, yes today you can get a ton of that out but its still going to have it. You also need Modified Exhaust for the Turbo setup so
there is new Header / Headers then the Tuning to Tweak a Turbo needs to be done by a Top Notch Shop with a Chassis Dyno for best
results. You would be surprised how different each shop tunes Turbos they are also more temperamental. Also you got to watch them
like a Hawk for Oil Leaks. Too much space filled up for a Turbo to do maintenance and a ton more stuff to remove when things have to be done.

I owned a GNX and a Turbo T Regals while they were dependable Vehicles still took a lot of upkeep and extra Tuning to get them
to wake up where I wanted them.

Id go with a Supercharger truthfully vs a Turbo. Ken Bell, Magnuson, Whippie etc.,

Cramming all this and then get it right id Hard Pass... If you want a twin turbo then its a lot more stuff to cram in there.

 

Thanks all, very informative and helpful. I think I will look into the supercharger.......or maybe an older Hellcat!

 

Older Hellcat would probably be best so its got all you need and everything is already setup for the power etc.,
Also there is now some decent deals time to time showing up. Good Luck.

 

Superchargers are usually always better than a turbo on V8s.

IIRC it is because of the supercharger size is limited on smaller cars and because the supercharger leeches horsepower.

For the cost of upgrading, it would be cheaper and more reliable to find a used Scat Pack.
