6th gen 4runner is 4th gen Tacoma SUV

The new turbo 4s aren’t even high strung. Most flatten out around 5k rpm. They’re just dealing with high cylinder pressures at low rpm to give good torque, which has been successfully engineered in many instances without issue. Mazda has had a turbo 2.5 with close to identical power and torque ratings as this Toyota motor for more than half a decade without any real issues

 

I'm curious if a 4th gen owner can chime in as to what their truck redlines at, my guess is somewhere around 6-6500. Yeah some people have oil consumption issues on the earlier model (came out in 2016 CX9) but pretty rare.

 

Also the Toyota engines are purposely engineered for truck duty not to go fast. If someone wants a fast truck they should buy a Ford or Dodge small weener mobile.

 

Most factory turbo charged motors are not particularly high strung or high boost. And they're also not typically (across the board, all manufactures, turbo in general) as reliable as a naturally aspirated motor. That's just the facts. And the more you string them out, the less reliable they are.

I'm not saying there is no place for a turbo. I'm not saying a turbo is inherently "not reliable." But the facts, statistics, and anecdotal evidence shows a forced induction motor is less reliable.

That being said. Toyota has a pretty deep history with Turbo motors. I wouldn't say, for me, it would be any kind of deal breaker. But it shouldn't be dismissed off the cuff... and the specific point I make is it CERTAINLY shouldn't be dismissed using an F1 motor as some kind of evidence.

 

Do you have any decent reliability data on the modern turbo motors of the last decade, or are we still living with the ghosts of the 90s turbo cars?

 

Its also a strange comparison because F1 engines are 6 cylinders...

 

It is also not true that an F1 engine lasts 1 race...

 

Yep those little Maverick's seem to scoot along, 0 - 60 in the 5's.

 

LOL. People are actually surprised the 4Runner is a SUV version of the Tacoma? When has it not been heavily based on Toyota small pickups?

 

This thread is for the most part a waste of time due to OP

 

You are correct. I think a lot of people may see the displacement numbers on an F1 (and Indy for that matter) and assume it's a 4 banger. Because a displacement of 1.6l is typically what you see in 4 cyl in normal engines


Either way, the comparison to ANY race motor is ridiculous. Especially if you're talking about reliability.

Unless you think rebuilding an engine every 500 miles and replacing the motor every year (if it makes it a year) is "reliable."

 

Lmao... if you think those motors aren't fully rebuilt after every race, you're crazy. And the only way the engine is used a second year is as a spare or sold to a lower race team.

 

I agree Toyota should get back into Formula 1!!!!

 

Cool, then see your way out. No one will miss you.

 

Yeah, I was thinking they were 4 cylinders and around 1800-2000 cc's, so clearly I'm the one not familiar with F1, lol. I'll have to see where I got that from, if it's from F1 15-20 years ago, or some other racing series.

Anyways, I think the point still stands that you can squeeze power out of a turbo 4 (Mitsubishi Lancer, anyone, as another dated example?). But since OP just made this thread to argue, it doesn't really matter anyway.

Hell, we could even go to the performance section of this website for people running turbos on the 2.7L Tacoma engine, which has proven to be a robust and powerful platform as well.

 

Article 23.3 (a) of the 2018 FIA sporting regulations states: “…each driver may use no more than three engines (ICE); three motor generator units-heat (MGU-H); three turbochargers (TC); two energy stores (ES); two control electronics (CE) and three motor generator units-kinetic (MGU-K) during a championship season.”

F1 engines are not rebuilt, but instead are replaced. Drivers are allowed to use three engines a year (and other engine components) under current regulations.
A starting grid penalty will be applied to drivers who need to change their engines (or other power unit parts) above the allowed three engines.

They are used for multiple races without a rebuild. They have a spare engine allocation limit per season.

 

20 Years ago F1 was using V8's 2006-13
The V-6 hybrid was introduced in 2014.

There is a interesting chart at the bottom of the wiki article that shows the engines /rules over the years.

LOL... pretty sure you're not going to "have any decent reliability data on the modern turbo motor of the last decade" that is going to show proof a turbo is as reliable as naturally aspirated.

Turbo is more complex, more parts, more places to leak oil, more prone to fail due to outside debris (blades and balance of blades). They are also more maintenance intensive, expensive to maintain, and there are also things that should be done with a turbo most people don't do and/or are unaware of... warm up before driving, not lugging the motor (of particular importance to the subject at had - an SUV with a tow hitch). Cool down prior to shut off.

You can find MANY instances of a million mile naturally aspirated motor... I'll bet you can't find many million mile turbo motors with the original turbo intact.
