besides the 6.4 manifold and z automotive controller what other parts are required? Going to start getting it all together to do this

A 6.4 intake of some kind. New runner gaskets in the intake is well used. A micro2 tap cause the one that comes with the kit is for the Challenger or Charger I guess.

Have you read AWEHLAGE's page on his 6.4 swap? The wire extensions still have to be done on the MAP, IAT, and throttle body. Good info In that thread. Basic wiring stuff needed.

5.7L to 6.4L intake manifold swap

I gathered all the necessary information by searching online forums, Facebook and YouTube. I really only found one general source for the Durango otherwise many installs were for the Charger, Challenger and Grand Cherokee. So I decided to compile all the information and make this post for my...

Yeah i went through it but figured most of it was for if you are creating your own wiring and not for if you have the harness from mmx. You have a link for the micro2 tap that you used? Will just any work?

Any will work. Got it from Amazon

So I have an unlcoked pcm from diablo and a i3 tuner from diablo. Can that control the SRV or is that just an hp tuners thing?

I know about that one, but there’s also one on the passenger side on the trans hump close to the firewall. It was easier to get to that the driver side one. View attachment 116183

Tony H posted this, it's where the can-c plug in is. Then you can control the rpm you want it to switch through the steering wheel controls. It's a pretty easy job. There's already hole in the firewall on the passenger side down in the heater/ac blower area. I used a hanger to make a wire hook for pulling wires through. I'll try to get you some pics.

Awehlage found a way to run it through the PCM but seems a bit more complicated than it's worth if you're going the Z Automotive way.

Started working on this. Doing a little at a time. Extended the IAT sensor tonight. Does the TPS sensor really need to be extended 16 inches?

Really it depends on which way you mount the throttle body. If you do it like it's normally on the 6.4, upside down compared to the 5.7, then yes.

For future reference. I remembered today saying I was gonna take some pics.

Passenger side fire wall down in the blower area. Already a hole there where my foam plug is. It's just covered by a black plastic cap. Wide band sensor and SRV controller cables through there now.

From the inside. Underneath the glove box. Behind the carpet is where the hole is.

Extended my IAT, MAP, and TPS. 6.4 ported manifold should be in next week. I’ll be using the mmx harness with z auto controller. Ignore the hvac duct tape lol. I rigged up my 6.4 afe intake to the 5.7 manifold just until the new 6.4 one comes in

You're probably not the first to do something like that lol

did you have to cut that hole or was it already there?

 

[zwade]

Nevermind just saw your older post, hole it there already

The z automotive srv controller is way easier to install and costs about the same to get all the components using the MSD method. It also suposedly helps with the hp drop off when the short runner valves open. Can't confirm that yet. When the weather cools I'd like the do a pre then post cam dyno.

The intake manifold swap itself is easier than you think. Lots of helpful videos on it. Mostly plug and play. If you get an aftermarket CAI specifically for the 6.4 it's even easier.

The wiring extensions for the throttle body and MAP sensor take the most time and precision. The intake wiring is only two wires. I just did them one wire at a time.

Too me It's more satisfying learning and completing these kinds of projects yourself. If you have the time to research, gather all the tools/parts, practice wire splicing and crimping. You should be able to do it yourself.

do you still have to tap into the injector wire with the z automotive harness? I’m confused on that part

No that's part of the plug in on the inside. Gets info about the rpms from there instead.

okay cool. Can you do a video from outside the engine bay to whereyou went through the firewall? I think i see it but want to make sure. If not no big deal. Intake manifold cane in today and i have to get the map sensor and intake runner control valve and i guess pcv valve as well to complete it

 

[HEMIWOT]

Yes those won't swap.

It's easier to find the hole from underneath the dash. Behind the carpet. It's up the firewall almost behind the glove box. Has a small circle plastic cap. It pushes out. Once it's out you'll be able to see the hole down in the blower area. Especially if you stick something through it to help you see it.

Another tip. If you have everything else installed and don't have the SRV controller on the back of the intake yet, don't run it. If the small hole isn't plugged really well, you'll have massive vacuum leak. Don't ask me how I know.

did you need adapters or anything for the 5.7 injectors to fit or did they bolt right up no issues?

Nope the injectors for the 5.7 cars and Durango are the same size as the 6.4.

Have everything i need to start this and realized i dont have the three bolts to mount the srv. Hoping the local dodge dealer has them so i can get this done this weekend
