Great write up! I almost followed suit with the whole deal but I'm going with the z automotive ccontoller.

Just picked up a 6.4 manifold with 6.4 fuel injectors included for my future cam swap.

 

This is awesome, good job. Glad i found this. Whatd you end up spending total?

 

Disregard LOL i just went through the messages i didnt realize all the pages my bad! Also, this turned out awesome, i am impressed. I am definitely not a DIYer so this for me would not work lol. Would you think it would be smart to take it to Dodge and say “hey lemme get a 392 intake manifold on this” or should i take it to my guy (who i am close with and trust) and do it there with him? My only concern is that this seems to be a very involved upgrade that maybe a dodge dealership would be safest dealing with? If i tried this i think my rango would catch on fire lol.

 

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.

 

yea maybe ill just take it to my shop and talk with him about it then if its not that bad. Just looking at the pics confused me lol

 

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

 

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 2016 R/T. There are minor differences between all platforms which small modifications had to be made most notably dealing with the emissions control vacuum harness.

I did not do the complete install at one time. This actually took me a couple weeks as I was waiting for parts and did a lot of the wiring before I even swapped the intake manifolds. I would say I have a total of about 15 working hours. You could probably slap this on and have everything wired in 3-4 hours and functional but I took my time and made it look as factory as possible. I did more than the average person would based on personal preference (aka my OCD) which you will see in the pictures. Enjoy!

Solid info!! I couldn't find this anywhere!

 

FYI. There is a less expensive and easier way to do this.

It is available from Modern Muscle Xtreme.

 

Did you need to use injector spacers for this? I've seen a couple of kits (they say the kit is for a ram) and they mention needing injector spacers to reuse the 5.7 injectors.

 

No you dont need spacers

 

Where are y’all finding manifolds? I didn’t search real hard today but I found one for $1000.

 

Ebay. Yeah they are very popular now. The one I found had the 6.4 injectors/ fuel rail, srv controller (which ended up being broke) and the map sensor. Was a steal at $970 shipped. That was sarcasm! A lot of people were bidding on it near the end. But for my overall build it was worth it.

 

For a $1000 I’ll hold off until I do heads and cam.

 

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.

 

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

 

Nevermind just saw your older post, hole it there already

 

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.

 

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

 

6509377AA

This is the actual part number.

 

Called 3 dealers and they are all closed until Monday 😭. Just going to get the srv controller harness in place today I guess until I can get to the dealer monday for the bolts i need

 

Hey where did you get the pins for the c2 53 and 60? I just pulled mine off of a 2015 sxt charger and I’m worried it isn’t going to work. Also, how is the SRV working for you, I haven’t seen much on this

 

Sorry for such the late reply. Did you get it all figured out?
