have you thought about how the Manual 6 Speed will go inputting 630NM!
heard the 4 Spd Atlas isn't up to the task either, 2 Speeds better.
would of thought any welding to Chassis would need to be done by a certified welder with a compliance certificate, is your Engineer ok with you welding it yourself?

That's alot of money to spend on a new car, considering you are swapping the entire driveline, plus I assume your doing a lift too and tyres. Almost a new jeep just doing that, though I herd you can keep the stardard auto with the new jks?
I am a lil worried about the gearbox, as its my weak link, but its the only one that fits at the moment. Ls wrangler in america are currently trying to squeeze a t56 behind the hemi and Chevy engine, which I would jump on straight away, but sounds like its gunna be some time yet.
The 4 speed atlas has been redesigned and is just as strong as the 2speed so not worried about that.
Engineer didnt seem to worried about the welding, more fussed about the lane change, emissions/noise test and pit pass. I've seen worse welds on the sites I've worked and pass with flying colours, so im pretty confident I have correct penetration if it does get tested.

50mm increase in track width would only apply to standard diffs i would have thought?

either way, good luck with it.......

Hemi & Diesel conversions shown in this Vid on JK Chassis, body's removed, gives a good view of everything. Note Hemi conversion in a 2012-2013 JK keeps original Auto Trans, its the same Transmission in a new Grand Cherokee, G/Box built by Mercedes.

swerve test was a walk in the park for my lifted JK on 35's, Brake test passed easy too, properly set up yours will do fine.

Yeh there's adaptors for Chevy, ford, Cummins n a few others but I haven't seen any for the later hemis. I just went with the Burnsville offroad kit. This is my first engine swap so I needed it to be as easy as possible. If I had the time and fab knowledge I would've gone straight with a t56. The getrag will handle the 6.7 hemis alright, as a few blokes in America thrash them n hold up alright, but they must be sitting on the limit.

Axles im not too worried about, the vsb 14 is a bit vague on that area, so its up to the engineer. Main thing is to get the engine passed first.

Great Project and well done doing it by yourself. I wish I had same capability to do it myself.

My piece of advise Do it all once if you can. Take the body off and do the engine conversion and suspension.
Reallocating the fuel tank with rear coilver suspnsion is great thats what i did but there are many many challenges and not simple.

Dont use the same factory fuel lines. Use standard heavy duty steel braided fuel lines easy to use and flex.

yea, i wish i had the skillz to do this kind of thing myself.. ohh well

I've been watching your build on jko and I can't wait till yours is finished, half wishing I went the same way for easier engine mods. Taking the body off would've been nice, but I don't have the room and the axles are goin to be 10 weeks away at the best. Its just too much time off the road.
That's sort of why I have held off with suspension for now, I would like to outboad the coilovers but will have to wait till the axles are here, I don't trust my measurements I till I can see all the parts in front my me. The suspension is going to be a big challenge for me.
Fuel lines from engine to tank I am swapping out for braided lines and when I do the tank relocate I'll finish off the rest of the lines

The Burnsville kit makes it alot easier, if you can spin bolts you'll be fine. Its more like a big game of memory that makes it hard
