Tacoma may get a 4cyl Turbo

Oh. I was thinking of a sedan. RX is the SUV class. Nvm.

 

The full size Fords are fantastic trucks. I've owned several. The last was a 2018 f150 4x4 with the 2.7L twin turbo Ecoboost. It was an amazing performing truck. My nephew is a tech at a Ford garage and says they hardly ever see a problem with the 2.7s,and regularly see them in for normal maintenance with 300k miles or more. I'd give my left nut to have that 2.7L engine in my '19 Tacoma!

And I would have to disagree with your comment about the reliability of Toyotas going away with a turbo. They along with every other manufacturer have been producing normally aspirated gas engines for years. Toyota's version has been known for exceptional reliability for years. More reliable than many of its competitor's. There is no need to think that if and when Toyota decides to make smaller-displacement turbo powered trucks, that they, too, will be as reliable as Toyota's products have been known to be.

 

I think the key to the reliability is to over-engineer and run the engines at a lower power output. It's when you run things at the max rated hp that they die quickly like the Mitsubishi EVO and Subaru WRX engines. Or worse yet the dodge neon SRT-4 turbo... even though I wanted one when I was a kid, you'd be lucky to find one not in a junkyard.

The 2.7 and 3.5 engines are no where near the hp/liter of other OEMs

That said, what are the chances we can get a nice little I6 turbo... in our trucks?

 

when I was truck shopping early this year, I found out the new ranger was going to be a turbo. No thank you. I watched one of the "truck repair" shows on cable, and they had an F150 in there with 60k and both turbos were bad and needed replacing or rebuilding. Pretty expensive. I haul my boat in the summer, and I wouldnt want it on the turbo all the time, which I think it would have been. Boat weighs 4k. If I can help it, I'll always keep my vehicles Normally Aspirated. Just dont want the headaches. My cousin has a newer Mustang that is supercharged, and I know there are a lot of variables, but the engine let go at 27K. No one wants to replace a newer Coyote engine at a cost of 10 grand ish. On a 3 year old car. Engines are not cheap. Neither are replacement turbos.

 

A NA inline 6 would be great in this little truck for those that haul heavy loads often. Longer stroke, more low end torque like a truck motor should have. Turbos are for diesels or high end sports cars when money is no object. JMO

 

@thdrduck Speaking of diesels, would it kill Toyota to offer it for their truck lineup? We are seriously missing out!

 

Toyota offers some great turbo diesels that would be fantastic in the Tacoma. The GD series would be great.

Adding a turbo to an engine is adding more failure points. When properly designed they can last a long time, but probability is not on your side as far as failure goes.

Still, in general, I would say Toyota has a decent track record when it comes to turbo engine reliability. Especially when compared to other manufacturers.

I like boost. I like reliability. I’ve seen some high mileage Toyota turbos that keep ticking, but those are usually low pressure setups. Modern pressure controls etc. can help increase pressure while keeping reliability in check, but you also need the manufacturer to not get carried away. Toyota’s usually on the right page when it comes to that.

Still, I always like to have options.

There is some information on the interweb regarding a new engine lineup called Dynamic Force Technology. Has anyone come across this? Looks interesting.
https://www.toyota.ca/toyota/en/connect/3066/dynamic-force-engines

 

They’re being used in a few models now.

Not entirely sure all the engines fall into that new term. M15A, M20A, and A25A for sure. I believe the V35A does as well, likely applies to all engines that use their new naming convention that includes displacement in the name.

The V35A tuned for a truck would be awesome in the tacoma.

 

I'd rock a turbo 4banger tacoma, but i wouldnt trade mine in right away. I plan to drive the tacoma until it drives no more (hopefully i get 10 years out of it, so 2027 here i come!)

 

No 4banger turbos for me. The 4banger turbos don't have bottom end torque. It'll be like the current 3.5 and have good mid to high range power.

 

Why would you think adding a turbo to say a similar 4 cylinder that is an option, would produce less torque than it does NA?

 

Not sure what NA means but I do know that tubos aren't effective until after 2500 rpm. Meanwhile most vehicles cruise at 1500 rpm... so still lots of shifting when faced with even the slightest incline.

 

Have you looked at the torque curve that was posted in this thread?

 

Does your nephew often work on a ton of fleet vehicles? The 2.7 has only been out 4 years (since 2015)..thats a lot of 300K vehicles. F150 owners must drive a lot more than Tacoma owners. Engines been out about the same amount of time as the 3rd gen tacoma and I wouldn't say toyota techs see regular 300K mileage when they are servicing them. The current 2.7 has only been out about a year, so I would say reliability is still out on that one.

 

Naturally aspirated* and that's an incredibly vague assumption you have there... Most diesels are turbo'd and red line at around 3500 rpms so are you saying the turbo does nothing until just before red line? A properly sized turbo will build boost when it is designed to build boost... For instance the new supra reaches peak torque (400 ft/lbs) at 1600 rpms... Do you mean to imply that it does that before the turbo starts building boost? Of course you don't; its specifically designed with a smaller turbo so there isn't much lag and the power it does make is available to people who do more than drag race. A small t28 on the current 2.7 could be building boost quite quickly, this would limot the top end that could be made but it would make torque down low which is where most people who drive trucks want it

 

No. I saw no torque curve. I'm still against a small turbo engine in my truck. Just me.

 

Hearing rumors of battery shortages for Hybrid models ....

 

Whaaaaaaa-?
