2.7 Turbomax

[Marky Dissod]

Best reason I can think of for a turbo'd 6-in-line, is to make up for the fact that I'm not getting a bigger V8 gottdamnt!

Inline 4 cylinder engines usually sound worse than V6 because they are less balanced. I6 engines are inherently balanced so they generally sound very smooth and refined. V8 rumble is great for motor heads (I admit I am one), but most people will prefer the smoothness of an I6.

The Turbomax in my Sierra definitely has a different sound than a V8, but has a comparable feel to the 5.3L in my Yukon.

Somehow, despite that it SHOULD be easier to wrench on a 4-in-line / 6-in-line vs a V8, somehow, I doubt customers'll pay less for labor costs ...

No, they'll figure out how to cram it under the firewall further.......LOL

Been driving my Dad's 22 Silverado for the last month+ while my Burb is laid up. That i4 has some kick to it. Its way better on fuel than the dash is telling me and while I am not beating on it, I usually have the cruise set to 80mph. I am filling up once every 2 weeks on a smaller tank than the Burb. Its got plenty of power and the tires will break loose pretty easily on wet roads. My heart is screaming NO to a turbo 4, but my brain says me likey.

I started reading about it and found out there is a ** tune available straight from GM. In 2022, GM updated 2.7 block casting for added strength, went to a forged crank, and its getting the bearings out of the 3.0 diesel for increased strength as well. On top of that the turbo is water cooled. Some very cool tech on that 4 banger for sure. And while the 277hp figure is way below the 5.3's 355, the 464tq is a big step up compared to the 5.3's 383tq numbers

If CAFE MpG tests are going to keep tightening the noose every year, there's gonna be even more 4-in-lines & 6-in-lines than there already are now.
(If you REALLY wanna throw up ... more 3-in-lines too! ... )

There's one upside we can hope for though:
If they're turbocharged, they may turn out to be an even greater bang-for-the-buck in terms of performance improvement potential than the Syclone and the Typhoon.

The LB4-ZR9 is STILL an underrated engine to this day ...

Hold your throw up, but I also have a Bronco Sport with a turbo 1.5L 3 cylinder. It gets 30 mpg and moves the little Bronco pretty good.

This engine is really built well. There's a few videos behind the durability of it. Built very stout and specifically for trucks.

I've heard that GM is going to give a 6 year/100,000 mile engine warranty on the 2.7 in the trucks. Do the same thing for the SUVs, well I'll bet there are some burned DFM customers who wouldn't mind a warranty like that.

Pass, they've been making v8s for like 80 years and can barely get that right, imagine a turbo 4 cylinder

After getting 29.1 MPG going 73-75 miles per hour from Michigan to Florida and back in our 2022 3.0 diesel Suburban I will never go back to a gasoline engine. 765 miles of range was flat out awesome!!!!!
