2017 DCLB Cracked Block

[

Trivia:
Cummins use of the word automotive is not ironic, it's accurate. The word automotive is about 60-80 years older than the automobile. It was first used to describe steam locomotives or tractors - either field or rail. Auto (self) Motive (powered) The Society of Automotive Engineers was established to create standards of manufacturing and testing to ensure safety (with ANSI and ASME) of steam engines.

Carry on with the inane bickering. The I4 should have a slight edge on longevity due to the time honored engineering principle of "design the engine to be under powered and it will last longer" But at the same time suffers from the idiotic cost saving decision to bolt an aluminum head to a cheap ass grey iron block. Both engines are probably going to still be running when the body rusts away or the truck is taken out by collision damage.

 

The same can be said of the 3.5L 2GR FKS V6 motor, which gets up to 318HP rating in the Lexus line up, and only 278HP in the Tacoma.

For 13k i'm going 4.7 and never looking back.

 

omg!

 

Not really. Having a slightly less power version of a more powerful engine is not the same as a designing a low to medium powered engine.

Using a standard instead of one engine to another will be more useful. One unofficial standard widely honored is the 1 HP per cubic inch rule. If the engine makes 1HP/CI or more it's generally considered high performance. If it makes less than 1HP/CI, it's a standard or low perf or golf cart whatever. Not exact but a reference to demonstrate output.

Lexus 2GR-FSE 3.5 (213 CI) 318HP 1.49HP/CI
Toyota 2GR-FKS 3.5 (213 CI) 278HP 1.30HP/CI
Toyota 2TR-FE 2.7 (165 CI) 159HP .96HP/CI
Honda K20A 2.0 (122 CI) 221HP 1.81HP/CI

Just for fun:
Ducati Panigale V4R 1.0 (61 CI) 234HP 3.83HP/CI

 

so the 2.7 is a golf cart engine.

 

Everything is relative. If, as according to the hearsay on TW, the Tacoma engine has the same crank, block, bearings, and piston rods as the higher HP Lexus motor, in theory, they should be well within their design limits in the Tacoma.

The Hp/cylinder formula only matters when comparing two identical engines, I would argue.

Regardless.......it’s all just speculation anyway. One could easily make an arguments the 2.7L litre engine is “stressed” trying to move the same heavy Tacoma around as the V6.

Time will tell. At least the 3.5L V6 isn’t one of those poorly designed and built Japanese 3.0Litres (3-leaker). I’m glad my V6 was made in USA, where the people know about V-motors.

 

It's not hearsay if the part numbers match is it? And realistically 311 vs 278 isn't didly squat. Look what OV is doing with turbos on the 3.5, 500+ HP on bone stock internals is impressive. I haven't had a 3.5 apart but the engine schematics show the design and specs, the "6 bolt main" and forged steel crank is a far cry from your typical American V6 with a 2 bolt main and cast crank.

The HP/CI (not HP/Cyl) is a long honored indicator. Because four cycle internal combustion engines are all more similar than they are different. But within that very wide designation, engine state of tune can vary greatly. The same tuning tricks to turn a 200HP 350CI Chevy into a 600HP can be used on a 5.0 Mustang or a 4.0 Supra. A lower state of tune (but still good quality parts) will almost always mean less performance but longer life.

As far as the 2.7 being stressed...It's still plenty strong enough to push the Tacoma, it's just not gonna be fast. Hell my 3.5 isn't fast either, I'd just say its less slow. In any case, my opinion is the 2.7 and 3.5 are pretty solid designs and both will last a while.

I work for a Jaguar Land Rover dealer. I looked up the engine cost for my wife's 2015 XF R sport the other day for giggles. $32,XXX for the long block. Thats without labor and supporting pieces. The car stickered for $62,XXX in 2015 and we paid $26k for it with 48k miles in June 2018. The car is worth roughly $18,000 now. If it ever blows an engine it'll be getting LS swapped. Lol.

 

Agreed. People seem to forget that full-size to trucks from 40 years ago made similar power as the 2.7L and had similar GVWR.

As a 2.7L owner I can attest to the fact that it is not stressed even with heavy loads, it's just slow.

 

What American engine is still 2 bolt mains? The last one I can think of at Ford was the old Windsor 5.0 and they haven't used it in 20 years. Granted I'm more familiar with the V8s but Ford and Chevy have used deepskirt blocks with cross bolted mains since the 90s.

Is that not the definition of stressed? It's working hard to get out of its own way and it can't. And on old V8 may have made the same peak HP but had more TQ and HP across the range. They can't be compared.

Edit: Sorry OP. This situation sucks and so does the derail to how the 2.7 is more reliable. Hope it all works out for you.

 

Power and torque are a big difference between 40 years ago and the 2.7L. The torque the engines put out would pull the truck and a half dozen Tacoma's. It would barely even struggle.

 

I never claimed the 2.7L made the same torque, because it doesnt.

My point is slow =\= struggle

 

Sorry OP for the Highjack. Too bad they did not have an adult version of TW. I I Did Notify the Mods for the HiJAck, Childish behavior .... Please let us know ... or maybe start a new thread and hopefully leave the children here ...

 

But... but... daddy! We want to play too!

 

Childish behavior can be fun as long as you don't get personal. As for highjacking the thread, anybody can post what they want in any thread any time they want provided the board TOS isn't violated. This is how it should be.

 

Ooooohh, you gonna get reported, (again.)

 

OP

Updates ?? Hoping u get it all fixed up at NC.

 

OP you got people confused. I’m assuming you forgot the 1 to make it $13,899.00? Some thing you’re only getting 1/3 covered.
