Mazda inline 6 coming out too.
What's old is new again I guess. They saw BMW and Mercedes do it. Small turbo inline 6 can be put into an engine bay just fine. I guess that's also a part of it. The turbo is easier to package than say a V6 and it's smoother? |

I-6s package fine, longitudinally. If you like your shit sideways you have bigger problems.

Inline 6 CYL Hybrid is perhaps the best drive train for most people.

LOL. V-8 owners are going shit the bed when this thing beats their "It's a hemi!"
"Where's muh Vroom Vrooms?" |

Quoted: That's a problem with DI only engines. Port injected and dual injected engines don't generally have that problem. View Quote View All Quotes View All Quotes Quoted: Quoted: Quoted: Quoted: They never should have killed off the 4.0. One of the most bombproof engines ever made. ETA: first thing I would do is delete all that EGR crap. That's an interesting take. EGR systems have been on gasoline engines for decades, and they don't cause many problems. Deleting it would likely require thousands of dollars in hardware and tuning, and even if you somehow still think it's worth it, that stuff probably won't be available as the vendors producing it have been dick slapped hard by the EPA. EGR absolutely DOES causes problems, in the form of heavy deposits on intake valves, in modern engines. If by "thousands" you mean $500 for a tuner and a couple of block off plates, then yes. That's a problem with DI only engines. Port injected and dual injected engines don't generally have that problem. Name the modern engines that are NOT DI |

The main advantage of a straight six over a V6 is that there are fewer parts. Fewer parts = cheaper to build.

Quoted: They never should have killed off the 4.0. One of the most bombproof engines ever made. ETA: first thing I would do is delete all that EGR crap. View Quote I liked the 4.0 and had two jeeps with it a Cherokee and a Wrangler. But it had a major flaw, it shat right next to where it ate. Making a proper turbo instillation impossible. This new engine fixes that. Intake on one side, exhaust on the other with the proper # of turbos for making good low-end power with limited lag. Whether the rest of the engine is made to tolerate MOAR BOOHOOHOOHOOOST or not remains to be seen. |

Quoted: It must be one hell of an engine if they decided to adopt an inline 6 which is typically a packaging disaster. View Quote Only one bank = more room for turbos. I'd guess the packaging is the main reason there aren't more I6 engines in cars now, but Chrysler and Mazda are both releasing new ones soon. Seems like the smoothness and performance under boost outweigh the negatives for them. I think I6s are cool and most have a torque curve (line really?) that is arousing. Only thing better is a V12. |
|
With modern cylinder sizing (long and narrow) and the switch to electric accessories the space needed for the engine is reduced. A lot of the newer I6s are as long as older I4s.

I eagerly await some compact I6 crate engines to put in one or both of my MGs
edit: modern crate engine/ECU kits. |
|
my 4.0 in the LJ is a tractor engine.
But I have no expectation of speed, but low end torque with 5.13's - it scoots up stuff on the trail. |

Quoted: Name the modern engines that are NOT DI View Quote No DI period? Off the top of my head, the Chrysler Pentastar family and Hemi family, the Ford 6.2 and 7.3 in the Super Duty line, the older Toyota stuff (1GR and 3UR), and some random Korean engines that are still holding on. But that's only part of the picture... Quoted: There are plenty that are dual injected using both direct and port injection. His point was that those engines who utilize both tend to have less issues with carbon than direct injection only engines. View Quote Exactly. Dual injection systems were a little slow to gain traction, but they've really proliferated the last 4-5 years. Toyota opened that door with Lexus products around 2006 or so, but at this point, most of the Toyota corp portfolio and a whole lot of Ford's products (including the ones they really care about) use dual injection. |

Quoted: My 4.6 stroker does alright. https://www.ar15.com/media/mediaFiles/171820/Capture_JPG-2275508.JPG View Quote Stroker versions of the 4.0 are impressive in terms of torque and HP, but they don't address the BIGGEST Achilles Heel of the old AMC in line six engine series......they cannot be made fuel efficient to reach current CAFE standards. |

No thanks.
Two years minimum to detect and iron out the bugs on any new engine. Twin turbo? Oh boy...maybe make that three. |

Quoted: I-6s package fine, longitudinally. If you like your shit sideways you have bigger problems. View Quote How so? I6 is modular to an i4. If it's FWD config you use the i4. If the i4 doesn't have enough power you add a turbo. I6 for RWD/4x4 I4 for FWD, smaller vehicles. Add turbos if needed. |

That’s the bigger problem. Transverse i4's have their place. They are easy to work on also. IMO transverse V6s are garbage. Those shouldn't exist but understand why they did when more power was needed. Doesn't make sense now with reliable turbo engines. |

Quoted: OK, but it beats the hell out of your "jeep" engine. I'll take more hp, more tq, better mpg, and reliability any day of the week. Feel free to call it an "aeroplane engine" if it makes you feelz good. View Quote The 3.6 is a shit engine for a Jeep or a pickup. Peak torque at what....5k rpm? Cant make it up a hill at highway speed without bouncing off the rev limiter. |

I'd actually like to try that setup in an A100 van.

Quoted: The 3.6 is a shit engine for a Jeep or a pickup. Peak torque at what....5k rpm? Cant make it up a hill at highway speed without bouncing off the rev limiter. View Quote There are these things called "gear ratio" and "horsepower". They determine the speed and acceleration of a vehicle, not peak torque. An 8-speed transmission helps a lot. That engine does great in the Jeeps and pickups for that reason. |

Quoted: But it is still a Chrysler. View Quote Jeep straight six engines have been great in the past. That doesn't mean this one will also be good, but straight six engines in general are very solid engines. I always look forward to any new product coming on the market that isn't electric, so this is a win in my book. |

Quoted: That's pretty pathetic. And poor mpg to boot. View Quote Exactly. Its like people just keep saying how great the 4.0 was like a parakeet or something. Reliable, sure. Good offroad, yep. Easy to work on, sure. Thats it. My tj rubicon with 4.10s, 31s and manual could barely tow some atv's and 2 people in the back. It just could barely make it happen, really struggled. My 3.6 gladiator is lightyears ahead of that tj. |

*sigh* ok fine, I guess it IS time to get off my ass and turbo a 5vzfe.

Quoted: It’s pretty common to have a smaller charger feeding a larger charger. It reduces lag. The only thing better than a big turbo is a big turbo being fed by a smaller turbo.
