excellent info- ok, i think we are in agreement we can beef up and do a stroker kit on the 5.7 and get more HP and forged internals. Then it can take more boost than stock. Do we have a price on this? just the stroker kit, installed, engine out and back in again? I have not calculated machine shop time in 10 years, and the last time i did a valve job was on an Oldsmobile 350R in a Cutlass, 1979 - so I am deferring to you for a cost.

Also in agreement, supercharging is an option, 7-8K from the kits I have seen, and some people may want to go that way. let me know if you guys want to make that an option above.

So should we just plan on upgrading the gears to 3.70 ? vote in on it and i will get pricing - just swapping pinion and ring gear right? nothing too exciting? besides probably adjusting the damn speedometer! ugh.

AWD- low range vs launch etc....I get it- up to you guys if you think its worth it for this project - I don't mind researching it, but personally, I am more like Ekaz, I wont launch anymore, not even my SRT Charger. I did my 20 years of that and now the shit cost way too much when you snap an axle or a crankshaft, of which i have done both- damn B&M Shift kits! The way I think is fair is if one person thinks they may want to go down the road of a SC, or STroker, or AWD conversion, I will get it on the list and we will figure it out, but if no one has any interest, and I don't have any interest, we can shelf it. I await your replies. I am thinking the gear upgrade is pretty painless and would help us be apples to apples, as the tire specs and the weight, all are important items to consider.

I don't think you can buy just a gear set.
Both front and rear diff along with the axles are different...beefier, along with the transfer case.
Plus they have electric motors attached to them so even if you get them in, how do you plug them in so they work as designed?

Only option that looks swappable is the V6 3.45 front and rear diffs which seem to bolt in. I know the rear will, not 100% sure on front as I have not researched the axle P/N's.
Either way the speedo will not need correcting.

Brembos and wheels and tires 4k

 

[MotorCityMade]

I didnt see SRT instrument cluster, wheel flares, rear fascia, srt floormats, quadratrac single speed transfer case system on the list. Lots of options out there to upgrade 100hp if money is no object. But then again for under 70k OTD with a mopar lifetime warranty (if available on SRTs) could have exactly what u want till the wheels fall off.

Good stuff MotorCity- I got floormats up there in the 2nd section. Good catch on the cluster. I will add rear fascia, and wheel flares as well. But you lost me on the single speed transfer case. I am already an AWD, is there something i am missing or is this along the lines of the AWD being different? I get confused in keeping this a list for everyone, but then just what I need - lol.

Not sure where you see these for 70K I have blu ray, rear entertainment, every freaking option imaginable and it came back at 75K. A deal breaker for me is I added power folding mirrors off a Jeep SRT along with all the wiring, modules and door controller. I had to get WIC to update my BCM, and they won't do that anymore. So for me, if I trade I lose power folding mirrors pretty much forever, unless I want to go Jeep, which is another reason I am doing the upgrade besides no desire to go back into debt.

You gotta hook up? Also never seen a lifetime warranty? you got a link for that on SRT? I have a Charger and I am interested in that.

 

[DocHoliday]

Chase, you got me - I am labeling this a - to each his own on this one.... I know you can update the PCM with a flash from AE, in 2018 once the codes and switches get released, but I am not sure going with a 3.45 is worth the trouble compared to a 3.09 ? is the V6 the same size pumpkin, ring, etc... as in strength? or is it more lightweight since its from a V6? should we keep this item open on just replacing the gears? or can you do some research on that, or are you certain? Did anyone seem Billions on HBO the last 2 seasons? Are you certain? yes, I am certain..... and millions of dollars fly. All on one word. Better than going are you sure? really? you sure? lol
I been up too many hours- sorry guys.

70k OTD would be for just the Truck in base form if you want to load it up, sure it stacks fast. But access to EP or FWP will pull it down some. The mopar warranty is offered when you purchase the truck. It will extend factory warranty at a cost. On a RT it is anywhere from 1500 to 3000, again depending if you get EP or FWP.
So 64k plus plus tax title...68k minus 1500 for FWP, plus 3k for warranty is 69.5k. Depending where you live amd what dealer u hook up with, it can be had for less. But i understand staying debt free is your main interest. For me, if i wanted to put 15k more into my truck, i would either lease a 392 charger/chally for a few years (since 15k in mods would not add amy value anyway) or bump to the SRT DD. All of the above will make the 15k disappear at about the same rate.


The mirrors- it is what it is. Either swap em, Or try to do them again and find a dealer who will update the bcm with new sales codes.

 

[Chase300]

I'm certain on the rear....it even shows full interchange with V8 on Mopar sites.
Not sure on the front...V6 could be lighter duty, did not look into it as I have RWD...I'll leave that to you.

One bigger point is while the SRT is using the same HP70 trans the R/T has, the rest of the drivetrain has been beefed up...transfer case, front/rear diffs and drive axles.
So you can add a Whipple and get SRT power+ out of the 5.7L but you won't have the drivetrain strength of the SRT.
Will it matter? Probably depends on how hard you run the truck.

I think this exercise is going to show the SRT is a bargain compared to upfitting an R/T to SRT specs.

 

[DocHoliday]

Motor- my RT was 56k sticker from factory- every possible option - it was an all black special order that as I said, i will be down to probably 25K by Christmas, with 22K miles on it. It all comes down to quality of life and what you want to spend your money on. to me, ratcheting back up to 70-75K depending on options, and that bigger payment isn't worth the money for me. I am already restoring an 86 Corvette coupe, and this is more therapeutic than for resale anyway. Keeps me off the tables in the casinos as well. But if i can get close to the SRT, enough that only the dealer would know by putting it on a rack and inspecting my axels or transfer case, I am ok with that. Sure, to make it 100% on all aspects would cost close to 35K from what I have found out so far and its the law of diminishing returns once you spend more than 15-18k IMO. But I figure there are a lot of guys and gals out there who cannot go get a 70-75K lease or loan and have a 2012-2015 ride and want to do this over a few years and love their ride again! As for the mirrors, believe me, if it was possible, i would still be weighing this decision- there are 3 sales codes that needed to be added for power folding, puddle lights and turn signals in the mirrors and no one will help with that. I have kept that as a side project for 6 months now and still keep looking. I would steal them off my RT now and put them in a box if i knew I could make them work again. Problem is got small garages and damn cars will not fit with mirrors open- no matter how close or careful you are. Anyway, I think we are on the same page now.

Chase- I honestly only went AWD because of the rain and we go to Mt Charleston a lot in the winter out here, and it snows! Not that i am breaking out the 20" tire chains, but it makes me feel better when the ground gets soft, or I see cars in the ditch it's raining so bad. It rains so infrequently out here, the oil just gathers all damn year old and when it does rain, it's like a slip and slide on some roads, so whatever I can do to give me a better chance of being safe. That goes back to why I am not too concerned about this 50/50 or 30/70 launch control with making this SRT upgrade. I actually would have preferred a RWD for this project like my Charger, but I got what i got, so be it. I am going to shelf the AWD- Axle- transfer case issues unless someone needs help. Before this thread/project is done I am sure some 2013 SXT owner is going to pop up an want to do this upgrade and he/she will need a new rear end anyway and a new tranny so we can address that then and get them caught up. If something breaks I will be surprised.... I am taking the 5.7 out of the Durango and putting it in my Corvette I am restoring anyway, so I have a dual interest in this project. I am keeping the 4+3 DN tranny in the vette as i just love it, I had it in college and that's also the reason for the restore. This will be my 3rd C4 restore, first one with a Hemi in it! can't wait to see how the car shows go with that showing up lol. So when you look at it that way, I had to get an engine anyway and I think the 5.7 is 425HP at the crank right? 360/390 at the wheels depending on what its in. So if I end up 325/350 at the wheels in an 86 Corvette that came factory 230HP, it will be nice and fast.

 

[Chase300]

I agree in the not taking on a big payment and loose one's butt on a trade up to SRT.
I like the idea of a 6.4L swap is it can be done for reasonable cost as I believe that would yield less problems than trying to build one out of a 5.7L.

If the 3.45's can be swapped in front and rear, should provide a nice boost to pickup and spits the difference between the R/T 3.09 and the SRT 3.70's.

On the Vette, a Hemi engine would be different, but I think it would be easier to install a LS engine...probably kits out there and should easily be an even swap for a late Hemi.

 

[DocHoliday]

Chase,
Ok, I will put it on the list as an option to go to the 3.45 , but those are the lighter v6 options right? just making sure so I notate that, or else you know someone will tell us we are donkeys and they won't work if we don't specify we know this already.

As for the LS sure, but are they giving them away somewhere? you got a site? I am not made of money, but it seemed like a real good idea and to be honest, the LS stock isn't as impressive as the Hemi stock. and that's the point- I want a reliable engine with good horsepower and free is for me when considering doing this upgrade. I am thinking we will need a new computer for this right? a 6.4 setup, so won't the existing computer go with the engine in my vette? I have already sold the old engine, stripped it down, removed all the old harnesses, its an empty engine bay and dash.

I know there will some issues with the drive by wire crap and all the other crap involved.....I have seen 5.7s for sale on ebay where they sell you a pallet full of everything necessary to run the engine. But it can be done, people put Hemis in old 68 Chargers, it can go in a vette and it won't kill me.

 

[Chase300]

I don't believe they are lighter, the rear is not...but I did not research the front diff.

 

[DocHoliday]

Can I get some more info on these wheel flares? I am not seeing it- or I already have it? the trim around the wheel well right?

 

[FSTDANGO3]

If you look up the R/T for the same year as yours at www.eastcoastmoparts.com in the Body tab you will find paintable flares. You can order all 4 and have them painted to match your paint code then simply replace your existing
STEVE

 

[DocHoliday]

Ok, thank you FSTDANG03 - I cannot tell from the diagrams what these flares really do- do they just stick out more? like Jeep fender flares? if the new Durangos have them, we need to get them, but I cannot tell the difference between that SRT and mine?

 

[15RTrooper]

Yes the wheel thin trim pieces stick out further.

 

[DocHoliday]

15RT- hey, thank you for the info on the flares... you got any pics of you ride? it sounds amazing from the mods..... sounds like you should have started this list!
but I gotta poke cause I am jealous--- what is a wroof ? my dogs says it all the time but I still don't know what he is saying.

 

[bgable]

Is that the part number for the SRT style hood? The idea to transform an R/T into a SRT is cool. Nice to see someone put in the effort with all the info needed, even if not wanting to do full on, it nice to see that some of the upgrades are very doable. I have a 2017 R/T and would like to put the SRT hood on for now.

LOL!! I never even noticed that before. I have done changes with it since I last updated that list. Here is the car from Velgens site. DODGE DURANGO RT // VELGEN WHEELS CLASSIC5 BRONZE // 22X10.5 - Velgen Wheels

 

[DocHoliday]

Bgable- thanks for joining us... Yes, that is the MOPAR part number for the hood. I have all the other items listed as well, still waiting on the part number for the heat shield/silencer. Josh Bjarko at Avondale Dodge, AZ is hooking us up with the best prices possible for doing these upgrades. He has been with me thru my Ram, my own Dodge and upgrades to my Charger. He has engines on sale now, and I am working with service on a swap price to replace your 5.7. I have already spoken to Plum, a Hemi Speed shop and others and I have some prices based on what part of the country you are in. I will be doing my own swap, so I will create a list of parts needed for the DIY people, unless someone starts their upgrade before I do, than hopefully we can get a list going then.

15RT - your ride looks amazing! very nice. I love the Jeep SRT steering wheel- I am thinking I might do that next. You got any interior pics?
