What would you do?

I think you might be the first person ever to say k series and torque for days in the same sentence. Typically a k series makes 30-40% less torque than horsepower and doesn’t make shit for power or torque below 3k rpm. Sure if you turn up the boost enough it will make more power than any of the stock offerings, but you’d have to push it well past 600 horsepower to match the torque of the 392 or diesel stock. Even then the torque would be too high in the rpm for technical trails, unless you go the Toyota build route and throw in a doubler. Not the route I’d go in a Jeep build, but to each his own.

I meant compared to any other 4cyl gasoline engine…besides going to a Cummins, but thats a Diesel. K series turbocharged are hard to beat in terms of power to weight, displacement, and money ratio in the 4cyl arena. Sure higher displacement will yield more torque stock for stock, but higher displacement also means gas guzzler.

I would have opted for the Cummings 3.2 or 2.8 turbo diesel.

I ended up putting a 3.6 back in it and selling it, and eventually got the 392 jeep.

Bc I traded my car in too, the 392 is my daily driver. I put the teraflex spare carrier on it, MC front LCA to dial in caster, got my old winch and light mounted, and 35s. I was kinda pleased that my tire/wheel package was net zero for weight gain. Tires are 10lbs heavier, wheels are 10 lighter. I had never run 35s before, honestly super stoked with them. Feels light, and I think capable enough for the trails I want to get on. For now at least.

From here I’ll get skids and probably rails. I hope to keep it fairly light bc it pulls daily driver duty.

This engine is truly great in the jeep, just man-handled the weight. It’s no racer obviously, but feels nimble and quick. Just super capable.

The black grill looks great on the white Jeeps. Also, where did you get the flat amber LED light And the brand?

Thanks! That amber light is the Baja Designs OnX6 10” light bar.

- Any Hemi or LS

Most of the shops that are known for engine conversions - rubitrux, bruiser, Dakota, etc - I think the majority of them advise that their swaps are for AUTO transmission only. So there's that. There's also the fact that I'd just be upping the ante. As in - oh you think FI is an adventure with unpredictable outcomes? Wait til you engine swap and mate to your manual transmission...enjoy the ride. Plus..now with the 392 out, I have a hard time ignoring the possibility of selling my Jeep (and a few other treasures maybe) and starting with a 392.

FYI: The owner of America's Most Wanter 4x4 was on the Truck Show Podcast in 2021 and mentioned they had done 1 Manual Transmission swap w/ the 6.4L and were hoping to launch one soon. Last I heard they were still data logging and tuning. Might be worth an email.

I ended up getting into a 392 a while ago, and it’s pretty great. Geared it 4.88, RCV front shaft, MC lift (started with 3.5” coils, and just put 4.5” up front last week), Tom Woods shafts, fox shocks and front hydro bumps , LOD rails, and just got Artec bellypan and exhaust skids. Nitto ridge 38s. MC steering linkage.
