Tacoma may get a 4cyl Turbo

Have fun with that. I had a hybrid highlander and hated it. Now you have two systems that can fail. I just dont understand Toyota. You have a platform whos main attraction is ruggedness offroad capabilities and reliability... then they put an anemic 3.5L thats so choked out oj high compression for emissions compliance and plan to put a fuckin turbo engine in it next.... bye bye reliability. Bye bye rugged offroad capability.

I cant wait for electric tech to catch up and we can get back to having monster torque, low center of gravity, super reliability, and none of this bullshit emissions compliance crap nerfing the shit out of performance and driveability.

 

It is more likely we will get a variation of this motor here. https://en.wikipedia.org/wiki/Toyota_dynamic_force_engines#V35A

 

I thought those 2.7 V6 Ecoboost did pretty decent on MPGs?

 

when towing*

 

Another good read. https://newatlas.com/toyota-tnga-engines/46830/
I am anxious to see what engine toyota puts in the Tacoma, whether in the late Gen3 or Gen 4.
With these new engines coming out I don't think Toyota has any plans for using turbo engines at all.

 

You are aware that diesel engines have had turbos for decades and do just fine off road, right? It's an extra component for sure but the existence of a turbo doesn't automatically make it an unreliable piece of shit if the rest of the engine and tune are done properly.

 

Are you really trying to compare diesel to gasoline engines?

 

When the topic of discussion is related to the lifespan of the turbo itself (which much of this thread is about), the comparison is valid.

As I stated before in this thread. Toyota and all the other manufacturers have been putting normally aspirated engines in their trucks for decades. The Toyota's are at the top as far as longevity goes with these trucks/engines. So common sense would tell you that WHEN/IF Toyota decides to put smaller displacement, turbo-charged engines in to their trucks, that these too, will last and last like we've come to expect from most all Toyota products that have came before.

 

I've been on this forum for decade, and each year I hear the same thing. Haven't seen them yet.

 

So is that a no?

 

I think sound can be a huge part of the equation. It’s why I bought a used flat six vs a new turbo 4, even though they were the same price and the new turbo 4 would outperform mine slightly.

Yep, the Maseratis sound wonderful.

 

The discussion was related to the lifespan of the entire motor, not just the turbo.

Yes diesel engines have had turbos for a long time what is your point. A diesel engine is vastly different from a gasoline.

Diesel engines are much simpler in design. They dont have spark plugs or any of the electrical ignition electronics. Diesel engines are designed around compression ignition (otherwise known as detonation or knock which can ruin gasoline engines). Because of the high compression needed to achieve this they are engineered much tougher and are able to be run much more reliably under forced induction, as opposed to gasoline engines which have to perfectly balance increased compression and heat with timing and detonation to keep the engine from destroying itself.

Furthermore stuffing a smaller engine into an increasingly heavy truck will also put more strain and wear on an engine that has to work much harder. Smaller gasoline turbos also completely lack low end toque before they can spool up which again less than ideal in a heavy truck.

 

Yes, maybe I shouldn't have directed my post as much at your comment. Much of this thread was discussing the specific reliability of the turbo itself and how often it needs to be replaced. A comparison between gas and diesel makes sense for such a conversation. In discussing the reliability of the entire powertrain, there is quite possibly more room for debate.

Thats not common sense thats blind consumerism brand fanboism. Putting a small engine in a big truck is recipe for unreliability as the smaller engine has to work much harder. Putting a turbo on a gas engine is an additional recipe for unreliability as youre increasing the compression and potential detonation. I'd never ever buy one, but go on and drink the kool-aid.

 

Wrong. The fact remains that Ford is having great success with their Ecoboost engines in their pickups. I know Techs at Ford garages that say they hardly ever see the 2.7 with internal issues, and frequently see them in for routine service with 300k miles or more. It’s not koolaid my friend, it’s just the future. Stop by a Ford dealer and test drive an f150 with the 2.7. Then report back....

 

So by your logic the current 4 cylinder is less reliable than the 6 in our trucks? Also a turbo doesn't increase an engines compression ratio. Detonation is kept in check by DI. No fuel in the cylinder it can't detonate and it cools the air charge.

 

Here u go diesel boys:

I'll never buy another 4cyl. I've had 2 non-turbo 4's FWD & AWD, and 2 turbo 4's AWD & RWD, and while they have their place, I don't want one. I want a turbo 6 in my Taco.

 

I have been happily drinking the Toyota Kool-aid in my '93 MR2 turbo for 19+ years and most of the 216k kms (134k miles). It still has original shocks and exhaust. Starter, alternator, broken seat bracket, broken trunk lock, radiator R&R, are the only non routine maintenance repairs in its 27 years. The cassette deck in the original stereo still works.

I would like to see Toyota offer the next gen Tacoma with the BMW inline 6 that comes in the Supra. They could offer it both with turbo or na version. Inline configuration by its very design offers more torque than a V.
