One guy fairly local to me had one on his 2011. Struggled to get 4psi.. there was a guy with a black 4.7 that was doing a m112. Seemed like he was pretty close to getting it done then fell off the face of the earth.

The stock block can handle 6-8psi using w/m and a good tune. A 05 pcm is needed to have any tuning. There's sc kit for sale on HTC. But that would be jumping in big time. My advice is set your goal for the truck and and then work toward that goal a step at a time. I've be working on mine since it was new one mod at a time.

Yeah sounds like the more ideal thing to do

if it's who I think it is , he's on Hemi Truck club under FASTHEMIRAM05 and afew other sites.

I've seen the M122 done on two different manifolds , one was the Indy Cylinder head , Mod man , the other was on a http://www.blowerdriveservice.com/store/hemi-61-custom-intake-p-859.html the nose and drive seam to be the issue.
Also the M122 for the northstar 04 CTS V can be modded to work on the G3 hemis, but the issue with that system is the Air inlet is in the rear of the blower case, and on a RAM truck its tight up against the fire wall.

Do you have a 6.1 ? if you do it will bolt up to your trans , and you can use your motor mounts.
as for the other stuff , listen to Chris(Chrisp2493) and Greg(Redtruck-VA) these guys will help you as much as they can .
Do you know if I would be able to use the computer of the 2006 srt8 jeep? And if I do put the 6.1 do I have to customs tune it for it to run right or will it be fine just like that stock

I'm not familiar with jeep electronic, so can't say. Get the pinouts for both pcms and compare them.

Personally I would expect it to run with the 05 pcm. But custom cmr tuning brings out better performance.

Also would I use the same harness I have on my ram now or would I need the one of the truck I’m getting the engine off

I don't know if the 6.1 harness will plug in directly. But it would certainly make the wiring of c4 easy. And it would plug into the 06+ coils. It would also have the added 02s you will need. So I would say use what you can of the 6.1 harness.

Awesome thank you it would be coming if an srt8 Jeep guy is parting it out

I’ve never used the super chips so I don’t know how well the run when you start getting the more modded engine. Normally a custom tune is the best way to get the full potential, you’ll need a diablo for that. Just figure out if you want to start with a 6.1 or mod the 5.7 and go from there

So I decided to go 6.1 I got srt8 already how would I go about connect my stock harness to the 6.1 and what do I need to change

What’s your situation right now? You have the 6.1 engine in your possession now? Is the 5.7 engine out of your current truck yet? What computer did you decide to use?

My suggestion, would be to start your own build thread and try to keep us updated with some pictures and stuff, it would help us help you better. It’s not a necessity, it just might help make things smoother

Good suggestion having your own build thread. What year is the 6.1 and do you have the harness and 05 pcm?
