Hello everyone! Long time lurker, first time posting! I have a 2015 Scat Pack with the manual transmission and unfortunately the motor blew, so I went and picked up a Hellcat motor/supercharger. I just have a few questions about doing this swap:
1. I am dead-set on keeping the manual tranny, will it mate up to the hellcat motor? will I need anything in particular to make this work?
2. in regards to physically installing the motor: trans mounts, motor mounts, anything else physically impeding the motor from sitting in the engine bay? Will I need hellcat mounts or will the current mounts work?
3. in regards to accessory components: power steering pump, a/c compressor, etc. Do I need the hellcat ones or are the ones that came with the scat pack fine?
4. in regards to wiring: Do I need a hellcat chassis wiring harness?.. or can I use the scat pack chassis wiring harness and connect it to the hellcat engine wiring harness? if I can do the latter, how do they connect?
5. In regards to cooling: I know that the Hellcat front bumper has spaces for the engine oil cooler and the supercharger intercoolers where the fog lights would be on my scat pack. Aside from this, are there any other cooling components that I will need to get? Also, will I need a hellcat radiator or will the current scat pack one do the job?
6. in regards to brakes: do I need brakes directly off a hellcat? or are the scat pack brakes acceptable?
7. in regards to suspension: what upgrades will I need to hold the extra power, if any?
8. what kind of rear differential will I need?

I think that the Tremec in the Hellcats has a higher power handling rating. I think at a minimum you would need a higher capacity clutch. I think the brakes on your Scat Pack would be 4-piston Brembos (at least that is the current Scat Pack setup). The Hellcats, SRT392, and SPWB's have SRT Brembo 6-piston brakes. Not saying that you have to have them, but just so you are aware that they do upgrade the front brakes on those vehicles.
I would suggest the front fascia as well. You'll lose your foglights. The Hellcat has the oil cooler and other heat exchangers basically filling up the space behind those fascia grilles.

It sounds like this is what you want to do and I won’t be a detractor. But... since you already bought the HC motor, I’d pose a question for an alternative build and let others weigh in. The HC motor really only gets you half way to where you want to be where you need to upgrade the transmission or at least clutch, driveshaft and probably the axels plus all the additional cooling upfront. Not mentioning the brakes...
What if you took that motor, pulled the SC and kept the bottom end but swapped in an appropriate cam and intake to keep it NA? Why? No additional mods would be required since you would be looking to build power on the top end due to the short stroke. So, the goal would be something like 550 HP at the crank at something like 6500 rpm but obviously the torque wouldn’t match the 6.4. You could sell the SC to pay for a lot of the parts. I’m assuming money is a factor to some degree otherwise you would have either bought a new SP or a HC.
Anyway, not saying you should do this or that it’s even a good idea, but I would be curious what this type of a setup would run like. Maybe someone has done it and can offer their experience. It would be a stout bottom end in a NA setup.
Seems as if the previous owner was neglecting her a bit too much.. oh well. This project will be extremely challenging but even more rewarding in the end. I got the hellcat motor with the supercharger for a great deal, so I figured why not go for it.
Hellcat motors are not a really popular swap just because of all the expensive accessories it takes to run the thing. Trying to buy all those things new will add up quick so you may have to get a little creative. You may consider buying a completely wrecked hellcat and swapping everything over just a thought! Keep posting I’d like to see how it turns out.
i dont agree with those who claim its a waste of alot of money. For about 20k including the labor steve will drop on in your srt or scat. Now I paid 23k for my car mint with 18k on it. Add 20 to that and ive got basicaly a zero mile almost hellcat for 20k less then the price of a hellcat. Add to that the fun youd have with that SLEEPER. Ya i know its not a hellcat for resale and the drivetrain isnt bullet proof like a hellcat but then im not racing on a track every weekend. on the street lack of traction goes along ways toward keeping parts from breaking. Every time theres a post like this someone says you should have just got a hellcat. Well not all of us can afford one. Back when i was young i bought a used gtx and hopped it up. No way i could have found the money to buy a hemi back then. Its why plymouth brought us cars like he duster and road runner. You could buy them cheap and there was fun and alot of pride in making them go faster then the big dogs. I still remember when i had my ls6 chevelle that if it wasnt king of the streets back then was dammed close. I got my but handed to me by a 327 350 hp nova that just had a set of headers and an after market intake and a holley. sent me scurrying to the speed shop to get some headers for the ls6!!! It ended up with a cam and some head work too before i sold it. STOCK IS BORING. What pride is there in beating someone on the street in a dead stock redeye. If i had 2ok id be visiting steve. how cool would a 6 speed green with envy srt with a hellcat motor in it be. You wouldnt see 5 of them at a car show.
I know I have considered it, not seriously, but just a thought here and there. To me the only reason to get another MOPAR would be to upgrade to a Hellcat or a Widebody Charger. And with as cool as (IMHO) my Challenger looks, I would only be doing it for the power increase, and it would be cheaper to trade it on a used Hellcat then upgrade mine, but I would end up with the best of all worlds. (other than no Hellcat blower and SHAKER ) SO, I should just have them do a mild build on my engine with the Magnuson.

im kind of with you. one day i look at my srt and thing supercharger and forged but what i really want is a wide body hell cat. Building a house right now so i have to prioritize but maybe in 5 years. I will be in a position then that i can afford a new one and still would be able to keep the gwe srt. My wife would probably divorce me if i sold or traded that car so id probably keep it. biggest problem i have is im not getting younger. Id be 70 in 5 years. I sure would like to get it now but it just isnt happening.
First off I’m super late to this thread. For that I apologize. Secondly I want to commend you for going the road less travelled. Often times folks say just buy a Hellcat. That’s certainly an option, but not as fun as building something with your own hands or vision. Now that I’m off my soap box I want to provide some important info that wasn’t addressed. Your TR6060 will bolt directly to the 6.2 Engine. The only difference between the Non Hellcat 6060 and the Hellcat unit are the internal 1-3 gear set. This allows the Hellcat Version to handle more torque. The Hellcat clutch is better because of the material in the frictions. They bolt right up to your flywheel as normal. Also the Axels and diff in the Hellcat are the same 230mm units as the SRT and SCAT’s with the difference being a 3.73 Hellcat Gear set vs a 3.92 Scatpak gear set. Your first gear in your TR6060 is 2.97 vs a 2.62 I believe for the Hellcat. You will have a much shorter range and have to shift more often. Since you’re a manual guy like myself I don’t think that is a problem in your eyes. Also the 6.2 Hemi and the 6.4 Hemi are basically the same block. What that means is your stock motor mounts will be fine to install the engine in your engine bay. The difference between the two blocks is the stroke and Cooling Jackets. The two engines share identical bores just a bit of information for yah. I have not seen a Hellcat piston in person but I’ve seen several online and they appear to have better ring land placement than the longer stroked 6.4. The most difficult part of this endeavor will be sourcing all of the coolers necessary to complete the project. Don’t forget you will need to upgrade your fuel system as well. Good luck and I look forward to seeing how this turns out for you.
I'm sorry, I don't understand what you marked, some type of photoshop work?
Hey, at least I thinked that was axually a werd, write?
I need to find a post I was reading yesterday, I think it had a type/wrong word count that was staggering. I think it was on a Jeep site, I was impressed. Anyone can typo, but this post was pure art.
Back to the original story, and Hellcat swap, what all is "required" just to get it in and running, like a check list.
1 - complete Hellcat actual engine with all accessories...
2 - harness/computer(s)
3 - power steering conversion?
Then what is "Highly Recommended"
transmission, driveshaft, differential, stuff like that
Hey everyone - wanted to provide another update on the car. It is now running, but Im having an issue upon startup where it smokes like crazy and smells like oil. I let the car idle for about 15 minutes and the smoke went away. Has anyone ever had an issue with valve stem seals on a hellcat motor? I feel like this could be the cause of my issue. Any advice would be greatly appreciated!
