Finally read about our engines....

For all of those complaining about "power", you definitely bought the wrong engine. For what it's worth, I like that Toyota is going for longevity and efficiency over power. I've had a 22R and 22RE and never had a problem with either. I'm sure a lot of thought was put into using Atkinson in this particular truck.

From wiki:

"The Atkinson cycle engine is a type of internal combustion engine invented by James Atkinsonin 1882. The Atkinson cycle is designed to provide efficiency at the expense of power density, or total power extracted per unit of displacement per rotation. A modern variation of this approach is used in some modern automobile engines. While originally seen exclusively in hybrid electric applications such as the Toyota Prius, some non-hybrid automobiles now feature engines that can run in the Atkinson-cycle as a part-time operating regime, giving good economy while running in Atkinson cycle, and conventional power density when running as a normal-cycle engine."




Design

 

why would that mean you bought the wrong truck because it has atkinson?
the point of atkinson is so when you're sitting in traffic or not in a situation where you need more power you save fuel.
When you need more power and not in traffic hit ECT and put your foot down a bit more?

If still not enough power well maybe you should have bought a V8 and not a V6 midsized

 

It's not a traditional Atkinson engine. That being said it has more power than the 4.0L and torque is the same. The power bad is a little higher but it's a smaller displacement and higher compression motor

 

The article you read doesn't apply to this engine. But keep going

 

I think Toyota should add the technology from the Tacoma 3.5L to the Tundra 4.0L V6 and put it in the Tacoma. Just my opinion.

 

They should team up with GM and LS swap it.

 

Meh, a smaller displacement turbo would have given better fuel economy and more power when needed.

And modern materials, designs, and manufacturing pretty much take out the lack of longevity anymore.

 

Yes, plus you also gotta understand it's not a full Atkinson cycle engine. They retard the timing when they want it in Atkinson. Here is a video explains more

That's what i enjoy about our engines. Great power when you need it, fuel economy when you don't. All possible because of Toyota's VVT-i engines. And yes, they could have a little more power, but Toyota is known for outstanding reliability, not ridiculous power. Domt get me wrong, their engines have some kick to them. Either way, i love them, despite the fact that i'll eventually be swapping my engine for a diesel

 

never let truth get in the way of a good internet troll

 

Since your truck is a Pre-Runner... you should perhaps go 4x4 too?

 

turbo isn't the best offroad since you need to deal with lag. So many are trying to do this turbo small engine shit now. Not a fan. And that's coming from someone who's never actually owned a N/A engine lol.

 

not known for power?
Might have a lot of mods done but that's a toyota powerhouse there. Toyota made one of the best engines ever. Strong, well balanced and one hell of a beast. One of the more powerful engines of the 90s.

Might not be as well known for power now days but their engineers know how to make a powerful engine. They just don't bother since most people want fuel efficient now

 

I'm willing to bet that not a single part is factory toyota in that engine. Like saying top fuel "Hemi's" are made by Chrysler

 

ok this one maybe not, but when I had my 93, which was bought with a blown engine and rebuilt it with a friend of mine we had it running 700hp on a rebuilt stock bottom end.
Very strong engines. Even from factory they said they only made 240hp but were more like 340hp. Just off tuning could have a stock 2JZ GTE running upwards of 500hp.

They were in no way ever a low powered engine.

 

Exactly. Hell for all we know that might not even be a 2JZ-GTE in that thing. If it is, even though those were solid motors that thing has all new internals

 

E Kanoo racing. Its still a 2JZ. Read an article about it before. its in the 2000hp range.
Runs a 2jz gte engine bored to a 3.4L single turbo all forged internals.

Regardless that cast iron block was a tank.
Even the 1JZ was a tank of an engine.

Point is to say Toyota doesn't know how to make a powerful engine is nowhere close to true.

... I like the red meat in this thread ...

The lag with a modern turbo design is negligable, the lag pushing down the gas pedal and actual response with the fly by wire is far FAR worse then turbo lag. What is weird is that my 2014 FJC with the more modern VVTII 4.0 system is very close to a normal traditional throttle cable response.

 

that's cause the turbos are so small lol
If it comes to 4x4 off road I'd rather a N/A though. But for daily driving I would agree a turbo is nice. Just not one like mine...its rather shitty now lol. Too much turbo lag and the turbo kicks way too hard.
