Swap 392 Intake Manifold onto Hemi 5.7: Complete Guide 

Thanks for the support recently guys! The part number for the wiring kit from mopar is 68064996AA.

Love mine, very noticeable difference. Car keeps pulling and runs way happier! My intake temps also dropped.

You da man. It’s videos like these that make RU-vid great

If anyone is doing the by piecing it all together new. Don’t forget the Pcv valve. It looks like the one from the 5.7 but it is not the same. Really ruined my day when I found out 🤦‍♂️

This looks cool kinda like the Ls engines with interchangeable intakes I look forward to my own build soon

Glad I found your video! Exiting days to come!

Well I'm watching a two year old video, but found ot very informative

I like your channel better than RT Life since he abandoned his entire cause for his channel and I never liked him much anyway.

You should tune your when adding performance upgrade if you want the full performance. And you need a better CAI.. Its not inclosed and you are sucking hot air..

Hey Donny maybe you can shed some light onto this. This was posted on a Fb page about the msd circuit boss not working. ATTENTION 6.4L MANIFOLD SWAPPERS WHO USED THE MSD/CIRKIT BOSS Andrew Wehlage and I have been meticulously going over the MSD setup vs the PCM method I’m using. After many nights of testing, looking at prints, finding proper pin out and MANY MANY other things. We can both confirm along with a 3rd party...that the MSD IS NOT...IS NOT controlling your Short Runner Valve...for those that are tech savvy here’s where it gets long...pin 1-2 on the SRV plug are 12v and ground...when energized it will function check the STEPPER MOTOR inside the SRV...to get the stepper motor to “open” it’s needs to seen a 5v signal on the microprocessor INSIDE the SRV which then tell a PIC chip to switch a mosfet that goes to a H Bridge that tells the motor which direction to operate...it will not WILL NOT return from that state until it is told. And there’s no possible way using only pin 3 in the SRV from the MSD is switching both ways...not to mention it sends out 12-14v on a 5v system..it would immediately pop that circuit.. if I can be proved wrong I would GLADY love to listen...but butt dynos and blips in charts don’t tell me it’s actually working...more than anything the 12v side is just powered up via latching relay at desired RPM and the Short Runner Valve does it’s function check at the RPM.

Were you able to reuse the 5.7 map sensor or did you have to buy the one you mentioned in parts video ? Also did that new map sensor plug the same as I know when I did this swap on my ram I had to use the 5.7 map sensor as the 6.4 was a different size.

I want to do this to my 08 rt I know they're different heads but can it still be installed without any other mods?

Just gained another follower I'm ready for this mod

oops am a day late on this one.was out of town yay. \edit: congrats on 2.02k current reading.

Hptuners has an option to turn on the SRV in the 5.7 tunes , i always saw that option and wondered what it does . I think you can enable it from the pcm itself wothout the msd box

Do you think there will be a difference in performance if I stay with the stock fuel rails over the 6.4

You flipped your throttle body to the inside so you didn’t have to extent your throttle position sensor?

What did you do about the fuel line being in a new location for the new intake manifold? I have an 08 5.7 with the 392 manifold and the fuel line does not reach around to the new spout. Any advice is much appreciated!

So I’m in the process of doing this mod, the manifold is on except the harness I’ll be doing that this weekend but rn I keep getting a engine check light, I looked at the code and apparently it’s says “Intake Air Temperature Sensor 1 Circuit High Input” what should I do

Well done! Great info !!

Do y put have a video on how you did the wiring for the air sensor?

Donny question I’m having some issues with my scat pack. I have oil lick around the manifold intake also under. would it be a good idea for me to remove it and see what is going on? I was thinking of taking it to the dealer but I don’t want them to come with some story.

Can you guide me for the wirering kit am doing the same on my 07 R/T can I get a link pls

Did you need spacers for your 5.7 injectors on 6.4 manifold?🙏

If I don’t get the window switch cause I have a mds delete and gonna get it tuned cause just put cam lifters etc would it work still? And I didn’t tap into the intake temp control or map sensor I just connected everything normal ? Is that bad

What control module do you 5.7 guys recommend to control the active runners when installing a 6.4 intake manifold? I’d like to add this mod before adding a wet plate nitrous system.

The little red breather filter what size is it and where did you happen to get it from?

Hey donny I have done the 6.4l intake swap as well and a cam my tuner has shown me that straight drop in the curve when on the dyno it dyno fine before the cam swap just wanted to know if you think they might have hooked it up wrong after they did the cam

I can follow this guide to do this swap on my 2020 Durango rt? Or is it too different from the charger?

Uk yo stuff man love yo channel bro 🔥

anyone know the part number for the module for the active runners ? Best place to buy it for the price? Definitely doing this manifold swap soon.

Do you think this would work on a 2011 Jeep Grand Cherokee 5.7 Hemi?

What about the vacumm line from the purge what did you do with that

When you did the 392 swap did you have to upgrade the gasket and spark plugs to a 392

Wouldn't it be better to just buy an aftermarket manifold?

Can I add a 392 hemi throttle body from a 2019 charger scatpack to my 2013 ram 1500 5.7 hemi?

And where can you find a 350.00 392 intake manifold?

It might be worth contacting your CAI company and ask if you can just buy a new tube for the 6.4 instead of buying a new CAI

Did u use the 5.7 inTake on the 6.4 manifold

Which rpm did it worked best for you for the MSD shor runner rpm?

is this doable on gen 2 hemis?

How’s the car because it been running?

Is the throttle body supposed to be upside down like that?

Just started gathering the parts. I have the intake complete from a car with only 2500 miles. Question....do I need the msd 8969 or will a jegs performance intellitronix n3211 do the same thing? About 150.00 difference? Fantastic videos btw. Can't wait to get started. Swapping cams from the same car as well. Mine is a 2015 Challenger R/t plus.

Awesome Donnie《☆》Definitely worth the money & elbow grease for diy project🤓👍🏾:*: Greetings from⛾Florida🤳my friend🤓🗣🔊☮✌👍🏾

Is this swap possible on a 2005-2009 charger?

How much stuff are you going to have to reverse to smog your car in california ??

Did you adjust anything on tune after install?

You should go E85 and re run rt drod

Aye bro will this work for the Durango rt 2021??

I have a 5.7 07 charger rt awd what all will I need

Did you experience a cylinder 3misfire when you added to your intake to your or notice your car has shake to it now??

Would I need a tune for this bro??

Would this be similar on a 2010 r/t

Can I put this on a 6th gen

I can’t find the wiring harness anywhere bro where did you get yours ?

I’m wondering if the cold air intake from a 5.7 fit on a 6.4 intake manifold? Anyone know???

What’s your intro song called?

How much power is your car making

Can you please tell me two things... can I plug my MAP without having to lengthen the wire? Also, can I drive my car without the harness installed into the actuator (still waiting on all electrical parts to arrive), and if so once my manifold is installed to the engine block would I be able to clip the plug into the rear of the Manifold without unbolting it again? Thanks!

Sweet 🎉

Hey brotha good video , do you have a link for the 392 manifold ? Kinda hard to find honestly

Hey Cooper! ( I have labs myself. Lol)

Awesome vids man! Question, I ordered the MAP sensor through the link provided in your parts video but when I got the part, it's way too small so it's not a snug fit in the hole used for the map sensor. Is there another part that I am missing? I can't find much online either

Where did you get the manifold from for that cheap

Damn is it really worth it spending all that for a tiny increase of power

will the 6.4 manifold fit shaker?

do ya’ll know if this voids warranty?

Does it fit a 2012 crysler 5.7 ?

Do you have a wire diagram for the setup? If so can you send it to me?

Another great vid From web_slinger_rt

L. Video

Would you recommend going with the 6.4 injectors and fuel rails or staying with the 5.7?

Would this apply to an 07 pursuit 5.7

I want to do this to my 08 rt I know they're different heads but can it still be installed without any other mods?
