Quoted: Your 3.6 is a minivan engine. 3.8 was the minivan engine. I had one in an 11 4 door Wrangler. What a dog. I put 4.88 gears in it (35” tires) and still no go. Installed a RIPP supercharger, a little better but not much. The 3.6 in my 2 door JKR and Gladiator is a vastly improved power plant. |

Lol @ using 3.0L and 2 turbos to eek out 400HP. And thats probably at the crank with no accessories.
You can get a used honda motor and 1 turbo and be putting out 475 to the wheels. |

Quote HistoryQuoted: Looks like they're using a dedicated turbo for each 3 cylinders. Maybe they can lop it in half to have an inline three cylinder version with just one turbo for their smaller vehicles.  Witha 3 cylinders per turbo (think smaller and faster spooling) couldn't they basically keep it constantly ready to boost and eliminate lag? |

Quote HistoryQuoted: I'll be interested . The slant 6s were damn near bombproof My first hand me down car in high school was a Chrysler Cordoba with a slant 6. That engine failed, I did a junk yard replacement and it failed, and did an AutoZone rebuild which failed after a 1,000 miles. When the engines did work I was not impressed with the 85 hp they had pushing a 3500lb vehicle. The AutoZone rebuild was garbage right out of the gate. Within a couple hundred miles it was making a ticking sound. I had to go to a specific shop they required who found nuts had come close in the head and there were bent valves and lifters. Their fix was to tighten the nuts and return it to me. Less than 2,000 miles on it and the engine seized up. AutoZone claimed since I didn't use their recommended shop to have it installed the warranty was null and void. There was no requirement of which shop could do the install when I purchased it. Fuck AutoZone. |

The specs will be interesting to see… I like inline 6s, add a couple turbos and even more so! My 4.0 HO Wrangler is severely under powered at the factory new 190/235 rating, with abysmal fuel economy too!
There are plenty of legendary I6s, from domestics like the GM 258, Ford 300, & Jeep 4.0, to Japanese engines like the RB26DETT & 2JZ GTE, and even European engines like the S54. Then there’s the Cummins engine lineage that started with the 6BT. I6 engines have fewer components than their V counterparts, are inherently torquey, and don’t have the same vibration issues. |

I'm not sure why people are shocked by this. There are multiple other car manufacturers using a similar inline 6 with single or dual turbos to good use in a large portion of the vehicle line up.
Those whining about power figures need to do some research. The X3M uses a nearly identical engine to this (3.0l and twin turbo) to push over 500hp. So yes, the performance is DEFINITELY there. A Ram 1500 with a 5.7 Hemi pushing 395 hp could swap directly to a new TT I6, have over 400hp (similar to the newest ecoboosts from Ford), increase gas mileage and yet probably shave .5 to 1 second off it's 0-60 time because of the better torque band. They'd literally be stupid NOT to do this. |

Turbo straight sixes make stupid torque. Look at some YouTube videos where they turbo charged a 292 Chevy and it’s Amazing. I like the design where the intake and exhaust are on different sides of the cylinder head. Makes it easier to flow. I’m very interested to hear the numbers for hp/tq.
