Would you trade your NA v6 for a turbo 4cyl?

Definitely agree on the fact that the small, world market diesels are romanticized here.

Side note: all of the 4 cylinder 5th gens I've seen (so like 2 or 3 on autotrader) are auto 4x2s. I don't think there was ever a manual transmission option. They did, however come with factory 4.10 gearing.

OA

That is probably correct, I think it was a 4spd or something goofy like that.
 
My main problem with this motor is the peak tq @ 4,400 rpm while it's great for a car it not so great for the runner. As CAFE standards increase these problem will get progressively worse and people will look back and say how great the 4.0L was. To be honest after driving a friends new Taco with the 3.5 I already feel that way...
 
just to stir the diesel pot again, and we all know toyota won't do anything

but these are vehicles slated (official, already released or rumored) for release with diesels this year or next

New Jeep Wrangler and Wrangler pickup
Chevy Colorado
Ford F150
Ford Ranger
Chevy Cruze
Land Rover LR4
Range Rover sport and Range Rover
VW Jetta, golf and Passat

Gotta love this pot getting stirred. Something tells me none of the vehicles that share the 4Runner segment will be close to the same price point, further perpetuating the "We want diesels, but will never actually buy one if given the chance" crowd. Knowing how crappy the ecodiesel is, I'm still going to have to test drive the diesel wrangler pick up, knowing full well I won't buy one.

I checked into the 2010 stats...the 4 speed auto is definitely correct. I can't even find the trans code but Toyota never wanted to sell them anyway I guess.

Some of us would buy one given the opportunity... and I'm typically known to do what I say I'm going to do.

There's a reason the Colorado had such a long waiting list and long delivery waits on orders.. and it wasn't because people were only "test driving" them.

Not calling you out specifically. But the fact is that's how these things play out. Enthusiast groups make up a small percentage of buyers.

I'm not sure which vehicle you're referring to having a waiting list in CO (that's probably the case for any 4wd there). I'm SURE it wasn't the Jeep Wrangler pickup that I specifically referred to in my post.

OA
 
The Chevy Colorado / GMC Canyon Duramax mid-size trucks.. Not the state! lol

Those trucks did and still do have supply/demand issues as people are ordering and waiting for this dying out diesel variant. :rapture:

Now, I don't know what type of cost/benefit scenario it requires to pay back an investment in a new power plant but if people are willing to pay then I am sure that cost can be recouped and bring in new business in the process. It's hard to believe the diesel is dying out if auto manufacturers are investing in it.

I don't get the hate from US markets. What it boils down to is this...if you don't want a diesel then don't buy one as most assuredly there will always be a petrol option (unless you are shopping for a Peterbilt).

Lol fair enough. The edit helps for clarification.

There is no hate for diesel in the market... There is hate for diesel by the EPA (and its actually legit). They are very dirty and destroy air quality.

Think of diesels as people smoking in public places. They cause serious health concerns and that is no longer accepted here in the US.

To keep selling diesels in the US, manufactures are required to add various scrubbers to try to improve the air quality concerns. These requirements will keep getting more and more strict and this will continue to make diesel way more expensive, inefficient, and unreliable. Unless someone comes up with a breakthrough technology for diesels... they are done in the passenger car/truck market. I give them 10 more years max.

The reason Toyota will never bring a diesel to the US market is simple. It would be a money losing move, and they are in the business of making money. Others (like GM and Fiat...) already had the motor and the tech...so very little investment for a short term market win. The economics worked for them, but simply won't for Toyota.

The GM 2.8 duramax is a great motor.. .but go drive one. It's not all that enjoyable. I saw plenty on the lot and the sales guy told me nobody is buying... the price is too high and you can get so much more for your money with a full size v8... Gas prices have a bunch to do with this lack of sales. When it goes back up... they will sell quickly (because people are so short sighted)

My understanding from reading, not experience, is that the internals are not strong enough for much boost and it's basically maxed out on power potential normally aspirated already. And they're kinda expensive engines. I've seen a few earlier model GR engines with twin turbos making right at the 1,000hp mark. One of the Scion GT race cars has a 990hp 4.0L, but it's pretty rare.

The other issue is that the 4runner has more than enough peak hp. I've never really wanted for more power in an absolute sense. I'm just not in love with the power delivery/gearing/transmission shift logic combination. It's not bad. Just not great. And I've made it worse myself by adding bigger tires and lift.

I don't know this for fact.. but the 1grfe should have no issues with a small amount of boost. I'm sure the rods and pistons are weak, but a few PSI is almost always within the tolerances. I would not race with it or tow at full boost for hours on end.. but for typical scenarios it should be just fine. I know gadget has been running his for a while..

The road block right now is the tuning. Really curious to see if the magnuson will happen. They seem to have some access to the ECU with the deal they made with TRD. I contacted them a while back about it and they responded saying keep an eye on the website. Not sure if that means anything.. but I took it as some indication it was close.
 
Screw diesel. I'd convert to electric or Hydrogen combustion in a heart beat.

I know what some might think, electric?... and my response is "have you ever been dusted by a tesla?" They take off quiet as hell and are gone. I'm sure the gen 5 has plenty more room under the hood to hold a larger battery for longer trips, so Toyota WTF?

Hydrogen combustion, not as efficient but relatively clean, probably a cheaper conversion and faster refueling times. draw backs would be converting a gas infrastructure for hydrogen and handling water exhaust in the winter.


so no to an engine upgrade, but living in reality, That rumored super charger kit has my eye.
 
I'm pretty sure diesel isn't going to happen. With the EPA cracking down on diesel tuning - likely entirely banning it soon and the ability of private groups to sue the diesel tuners for EPA violations, I don't think diesels have a big future in the USA.

As far as every model I've calculated, there's not a diesel available that will break even on cost over its life for people driving 10-20k miles per year. So they're basically all slower and more expensive to own. Hard to justify bringing new diesels to this market.

EPA does not have the authority nor a reason to ban Diesels. That's not what they do. "EPA Violations" - what are you talking about? And you're right, the market has dictated that diesel doesn't win.

Personally, I believe that low pressure forced induction, low displacement engines will start taking over most of the car/SUV/light truck applications for their ability to provide power when you want it, or economy if you're light on the throttle. Turbo technology is getting much better, and if Toyota offered a typical "over engineered, overbuilt for it's purpose" type of turbo engine for the 4Runner I wouldn't hesitate myself. But I'm locked into the V-6 as I am pinstriped as a MoFo :clap2:

Yup, it is, and there's nothing to be afraid of. 30 mpg on the highway, but 300+ lb ft torque when you need it would make most people happy.

As prejudiced as I am against Ford, and overstressed turbo motors, their ecoboost seems to work well enough in the F150.

As CAFE standards increase every bit of marginal efficiency becomes more important, and turbos are a significant efficiency tool.

The term "overstressed" needs to go away. The motors that you think aren't "overstressed" were once called "overstressed" by someone who grew up with 125 hp 5+ liter motors. Instead of calling them overstressed, call the old motors inefficient dinosaurs.

My main problem with this motor is the peak tq @ 4,400 rpm while it's great for a car it not so great for the runner. As CAFE standards increase these problem will get progressively worse and people will look back and say how great the 4.0L was. To be honest after driving a friends new Taco with the 3.5 I already feel that way...

No they won't. CAFE standards have nothing to do with power output of an engine, other than it clearly hasn't stopped manufacturers from increasing MPG and power at the same time. If Toyota went with an engine that was truly a downgrade in the Tacoma, that's on them. I have a feeling the new 3.5 with a half decent 6spd automatic would be almost identical 0-60 as the 5th gen.

Some versions of the tesla model S have a higher curb weight than the 5th gen 4Runner. An equivalent 4runner with batteries would make it a class 3 vehicle. I don't think any of us want that :)

When it comes down to it, thank Prius owners for letting the 4runner continue to exist ;)

Cafe dictates the MPG which in turn does effect the motors output since they must meet these regulations.
 
"Would you trade your NA v6 for a turbo 4cyl"?

Sure, if it had Volvo's 2.0 L specs: TC and SC 2.0L, 316 HP @ 5700 rpm, and 295 Lb-Ft @ 2200 - 4500 rpm.
 
"Certified motor vehicles and motor vehicle engines and their emission control devices must remain in their certified configuration even if they are used solely for competition or if they become nonroad vehicles or engines," the proposed regulation states. "Anyone modifying a certified motor vehicle or motor vehicle engine for any reason is subject to the tampering and defeat device prohibitions of this section and 42 USC 7522(a)(3)."

Add to that the ability of private parties to sue on behalf of the EPA

For example:
Diesel Brothers TV Stars Face Lawsuit From Environmental Group - autoevolution

And diesel tuning is dead. Ford already locks out the ecu so when you tune one now, you can never reset to OEM. The ECU recognizes a change and you can't hide a re-tune back to stock. So your warranty is void. Most owners don't know.
 
I would be interested in a turbo four paired with an electric motor that would help with torque fill at low rpm's or between gear changes. Maybe a top mount intercooler so the fake hood scoop would actually be functional.

That EPA fine is entirely reasonable and within their power to do so. For what it's worth, EPA also came out and specifically stated that they do not regulate off road vehicles (ie race cars and others). Quoting some news article (another post) that interpreted an EPA proposed rulemaking (incorrectly) means literally nothing.

But what I responded to was the statement that it was an EPA violation. It isn't an "EPA violation", it's breaking the law.

CAFE does not dictate MPG on any single car. It is a fleet-wide standard on emissions and fuel economy. It is why Toyota gets away with making 20 mpg SUVs, and why Ford (with the F150 a large percent of sales) went all out with lightweighting and turbo-downsized motors.

Car companies are exceeding CAFE, and the average power of vehicles has still increased for various reasons. See here, page 8 (pdf page 13): https://www3.epa.gov/fueleconomy/fetrends/1975-2015/420r15016.pdf

Porsche is going to a flat 4 turbo in the new Caymans (718) instead of the flat 6. So far a lot of people are buying them but a lot of the puriest are having a hard time jumping on board. I personally would rather have the raw power of NA instead of turbo. Most car companies are going turbo for fuel economy and such.
