Interested in this swap but there doesnt seem to be much info on it. Seems to be conflicting opinions but I know it has been done many times. Anybody know exactly what is needed to swap the engine and maybe the trans. Any input is appreciated!

I highly doubt this, as putting ANY VVT engine into a non-VVT engined chassis would create many potential problems, (lots of them caused by the VVT itself) probably making it not worth the time and $$$. Now if you took an early non-VVT engine and created your own 392 or ???, with either a 5.7 or 6.1-based engine, it would be quite easy and probably only require a good tune and some bigger injectors.

Not saying it can't be done but for sure, with the VVT engine, you'd probably be better off locking the phaser in a fixed position and completely doing away with the VVT. That would simplify things a lot.

It's also my understanding that some of the accessories are located in different positions than the early LX vehicles and some of the electrical plugs are different which would require some circuit chasing and re-wiring. Bottom line...there are many other ways you can go to get the engine displacement/horsepower you're after, without all the potential problems.

What kind of power are you looking for in your 06?

It has been done, check YouTube or look into it a bit and you'll see. It looks like the easier way is too lock the cam phaser which removes the vvt functionality so it can be tuned with the existing pcm. I'd like to know what it takes for the engine to be fully functional with vvt and active intake manifold. It bolts to the 5 speed nag 1 and looks like you cant use the 392 8 speed trans very easily which isn't the end of the world but would be nice to know how it could be used. Obviously the driveshaft and rear end would be needed aswell if 392 trans is employed. If I cant figure this out I'll stick to original plan but this seems very cool to me.

Man, I just want the 8 speed in my car.

 

Have you looked into making it work?

Anything can be done, but it cost. Guy in Miami took a wrecked hellcat and literaly converted a 06 Magnum into a Hellcat, but he used everything from the hellcat, dash. consule, complete interior, right down to the red keyfob working. I was truely amazed.

 

Any chance you know where this guy is, and does he have addictions he needs to feed? LOL. I'd love to just think about how much it would cost to make hemi magnum.

 

I'm happy to announce that a 392 with 4k miles is being installed currently and will be tuned after. The srt exhaust is also being mounted. I'll be storing the 8 speed trans, driveshaft and rear cradle until that swap is developed foolproof. Vvt will be retained as well as the active intake manifold. I'm very excited, this will be quite the unique build. I will post pics and a video once running.

My installers said they have dropped a hellcat engine into a charger of similar year aswell. Looks like anything can be done at this point.

Happy to say that the 6.4l swap into my 06 300c is complete and amazing. It is a 2018 stock 6.4l motor with my original nag1 trans along with my original rear end. Also it has the stock SRT exhaust. Much plans going forward including 6 piston brake swap, 3.92 getrag rear end and lmi true cold air intake which I have everything for just need the time. Can anyone help me upload a video here?

Now thats a clean install!

 

Very nice indeed. How did the tuning and computer work out?

 

Thanks guys, it was tuned by Chris Squier at hotwireauto.com Required was a 2009 5.7l pcm with a stock 6.4l tune, along with my vin written in. Also some settings changed regarding differences due to car being from 2006. It runs flawlessly and all the electronics work..its like the motor was in there from the factory. I have the 8 speed, hp70 transmission aswell but not sure how to put that in yet.

Nice. Did they have to pull the radiator and AC condenser.

 

There was alot involved in the swap. Several accessories had to be changed. Really it wasn't too bad though. If you'd like to know what all it took then pm me.

Any opinions on if I should remove the HemiC badge on the sides and put these 392 hemi badges on? Was planning on deleting the emblems on the truck lid along with adding a wicker bill.

Me? I would leave the Hemi badge on as is. I like a sleeper.

 

Omg can anyone point me into the right direction to swap hellcat engine with a8 into a magnum

 

Man I haven’t seen your posts in a while! Haven’t been on here in a bit but you always had something interested. Kudos to you!!! Only wish I had the money to do what you’ve done.

Thank alot. I haven't been on here much lately as it feeds the addiction. With my career picking up along with recent engagement and talks of babies.. turning wrenches has been put on the side. I daily the car, shes a beast.

Congrats on Engine/engagement/soon to be babies!!! Have any vids? i'm interested in the A8 swap. That's one tranny I want underneath me

 

Thank you, with regards to the 8hp70 swap I had the 8 speed sitting since I used the nag1. I searched for a solution that didn't involve swapping out the body harness and dash. German Sound Engineering was developing a solution for this. It wasn't foolproof just yet and I sold the trans and driveshaft only to find out they released the solution a week later... If I went the route of using the 8 speed I'd need to have a custom driveshaft made to mate with my getrag OR buy a zf rear end which I elected not to buy at the time of engine purchase. Anyways, here is the website for the standalone tcm to run the 8hp70. It's about $1000.

I should have just explained it all upfront as I've gotten dozens of pms asking how to do this. To start, if your car is a 2009+ the swap is much easier. This would work with non 5.7l cars aswell as long as your car has a nag1 trans. I'm sure there are other ways to do this but this way you dont need to swap out your dash and body harness. In this example we are talking about a 2006 5.7l car. Took a complete 2018 6.4l engine, used the 5.7l engine harness. The 6.4l motor mounts are a direct fit. You'll need to swap crank sensor for a 2009 5.7l one. Use your 5.7l power steering pump. Use a 2012-2014 5.7l ac compressor for the belt to line up(others may work I dont know). Use a 6.1l/6.4l severe duty radiator and then bolt back on your original transmission radiator. I used a 6.4l k&n cold air intake but had to cut off the heat shield due to where the power steering resivour is located(that could be relocated). The entire 6.4l exhaust including manifolds fits very well with the charger tips seating perfectly in the rear bumper cutouts. The engine bolts directly up to the nag1 without any transmission tuning needed to run but its recommended. The nag1 was used in 3.5l, 5.7l and 6.4l cars up until 2014 as the last year. The most important part is you NEED to use a 2009+ 5.7l pcm and have your vin written in along with a 6.4l tune. A VVT pigtail harness is also required for you to retain vvt and not have to lock the phaser limiter. Chris Squier at hotwireauto supplied me with the pcm tuned with vin written in, vvt harness and instructions. It was plug and play. Lastly you need use a MSD rpm switch to trigger the active intake manifolds short and long runner modes for full benefit. You could leave it as is or switch to a 6.1l intake manifold if you want to run boost without forged internals but that is a separate subject entirely. I hope I'm not missing anything. I still have a lot to do to this car. I started feeling greedy keeping this info all to myself lol. Enjoy.

AWESOME INFO!!!!!!!

Just to clarify you used your 06 5.7 harness? Or did you use a harness from 09-up?

 

Nice to see ya back. Always loved the first gen.. The 3" exh ya found for me is sounding good, lost a lb of boost though, better flowing I guess. Remember, "never give up who you are for anybody, not even for the love of your life" ahahahahhha. Coming from an old man that's seen a thing or two..

 

Was the crank reluctor wheel changed out on the 392 or just the crank sensor. I’ve been told that the wheel has to be changed to a 32T.

Only just seen you post. Christmas and all. Mine is a 2016 6.4 Hemi. Kept the reluctor wheel from the 2016 6.4 Hemi. Just changed to the sensor the suites my 2010 ECU. Because of my 270 comp cam, HHP suggested using a 2010 ECU to take advantage of it.
As far as CAN I haven't driven my car yet. Still mucking around with wiring and programming, but engine does start.

 

I'm sure the swap to a 09 computer was for the crank reluctor difference and the vvt and srv control. The eagle 5.7 has the 60-2 reluctor.

 

Oh ok makes sense now, is all the CAN bus functions still retained? Everything is ran through CAN bus I would hate to lose cruise control or climate control, anyone know if that’s a issue.

I'm not sure about the reluctor wheel but I retained everything like cruise control and climate control with my setup.

This REALLY makes me want to buy a donor 392 to put into my Daytona...
My bank account is beginning to sweat. . .

 

 

Does a 6.4 pcm not work with the 05-08 system? Looking at a power upgrade next year possibly, and going with a 6.4 crate engine seems like a really good option. Just thinking a 6.4 pcm would allow the active runner without a workaround

 

I am no expert but have been looking into this for my own potential swap. What I have learned from others is that the 6.4 pcm does not hook up or at all work with the 05-08 system.
The workaround previously stated is to use 09-10 5.7 ecm because it works in the Gen 1 system, but has VVT capabilities needed to run the 6.4, but needs something additional to run the active runners that the 5.7 never had. It is my understanding that this 09-10 only works with Nag 1 and running an 8speed would require a lot of changes to accommodate a 6.4 pcm or I believe some shops have devised a workaround for that.
Please, someone that can explain this better than I can, jump in and set me straight!

I used the 2010 5.7 Crank position sensor from Rockauto. Don't forget to get a connector with pig tails if you don't already have one.

 

I used a 2009 5.7l crank position sensor..same thing.

I have been running the 6.4l swap as a daily driver and have since put 40k miles on the motor with absolutely zero issues.
