Drop V10 E60 BMW motor in JLUR?

Tough guy! Reminds me of an old joke

A tough guy walks into a bar, looking for trouble. Orders a boiler maker. He downs the shot, turns to the guy on his right and punches him in the face.
“That's a right hook from American boxing.”

He drinks down a beer, turns to the guy on his left and kicks him in the belly. "That's a crane kick from Chinese Kung-fu."

He turns to see if anyone in the bar wants to fight. The bartender knocks him out with a blow from behind.

That's a tire iron from Chrysler Jeep.

Let me take a wild guess............Jeep with big tires and lift with a tiny piston????
I think I was super clear with my post that I have no idea if doing what I proposed is even feasible. So why come back with the "you're planning on spending 10's of thousands" instead of understanding that I was looking for guidance from the forum???

Wouldn't guidance include ballpark cost?

The S85 was unreliable enough in a sedan, especially the rod bearings which I hope to God you’ve already taken care of. You want to put it in a Jeep which you’d presumably take off road, put at weird angles, spend most of the time in low RPM high torque situations, and somehow get it to mate with a suitable transmission for the aforementioned?

Trying to think of a more ridiculous engine combination to illustrate this point, and it’s hard. Maybe if you tried to fit a W16 or one of these bad boys. Its also a BMW in fact.

I’l be waiting for my “tough guy” designation.

It was the wise-assiness which I don't think anyone wants on here

Is this your first day on the Internet?


You, and maybe a handful of others are maybe the only ones who don't. The rest of us enjoy it thoroughly.

As a Wrangler and BMW M car owner, my recommendation to the OP is to keep the two worlds separate. Both Wrangler and M cars have unique and wonderful qualities and strengths. But the vehicle architectures, design targets, etc are completely different. There are so many sensors and computers monitoring every connection and subsystem in the S85, it would take years and tens of thousands of dollars to do this conversion. And the only way to do it would be to turn the Jeep into a BMW. You'd have to use the BMW DME, BCM (body control module, etc), in addition to fabricating everything. You probably need to change every electrical component from headlights to window motors.

It makes no sense do this. In fact, I guarantee you can buy a used low miles E60 and a used low miles 392 and still it would cost less than this conversion.

Sometimes when you try to mash together 2 great things it yields a horrible result. You are proposing to mix steak and ice-cream on a plate. Enjoy each separately. Together they are nasty.

Will there be enough room for his angry grill with that thing?

He seems to have a BMW-ish disdain for larger-than-stock tires and lifts, so it'll be a pavement princess. No need to worry about it being tough enough to handle less-than-pristine situations.

I love steak and ice cream. Bologna and whip cream in a pinch.

Worse yet, you'd have to figure out a way to combine BMW electronics with working turn signals. That alone would make it a non starter for me.

For a BMW driver, the turn signal stalk can be repurposed for other functions. If I were to attempt this conversion, I'd make turn signal stalk down be rear locket, stalk up front locker, stalk forward both lockers. Extremely convenient since BMW-engined vehicles do not need turn signal indicators.

Agreed completely. You made me think about putting the 8,250 RPM screaming engine from my RS-5 in a Wrangler. Yeah, that'd be stupid.

@Bbino have you looked at conversion companies like this? Expensive, but it'd be drivable and significantly more reliable than the Frankenstein that you're thinking about. https://amw4x4.com/collections/wrangler-jl-conversions

Just lower your sights from a BMW to a lowly Viper V10, they fit in a TJ. There is Know How with many having been done, they come available for sale. At a fraction of the what you are looking at.

Here is sad, but interesting fact. BMW is the only major brand that does not have a single off-road targeted rugged vehicle. No body on frame vehicles at all. Not even something like a Passport Trailsport. Even Porsche has the 911 Dakar. Mercedes, of course has the G-Wagon, Audi is testing the Q6 e-tron off-roader. Lexus has the GX, LX body on frame off-roaders.

Not BMW. The closest they have gotten to it was a BMW X5 anniversary edition with some tiny all season tires that they called AT.

Given that they owned Land Rover for quite some time, you'd think some of it would have rubbed on. Nope. And both the Defender Octa and Ineos Grenadier are bowered by BMW engines.

Would be cool to see a BMW Defender or Land Cruiser competitor. Kinda of sucks they have nothing that can take NYC or New England pot holes.

Not a feasible option, having had the m6, the s85 is a 500hp, 384 tq engine. It’s a poor choice spec wise and was well known for being finicky and very hard to work on. Not to mention about a 10-11 mpg rating. This alone is enough to not even bother. It‘s about a 35k project to drop the hemi 392 in our jeeps and makes that a no brainer Vs the s85.

 

[Wabujitsu]

I'm not sure why I'm "tough guy" to you, but you already said the engine wasn't going to cost you anything. I was referring to the cost to make it work in a Wrangler.

Hey John, if I can be accused of misogyny by a woman for holding a door open for her, you certainly can be accused of being a “tough guy” for asking a benign question. Shame on us.

I wanna drop a school bus engine in one. Crazy torque.
