Are these turbos easy to replace.

TCCN says there's an electric pump at 12:00 in the video, so...

 

The turbo is in the front on the tacomas and I thought they had an electronic controlled waste gate as well?

 

That may be for the Highlanders and Lexus SUV's. Parts diagrams are confusing AF, but I've never heard a pump after shutdown on my truck like I did on my MK7 GTI that did have one.

 

Vacuum operated. Tundra's have the electronic one.

 

how does does that effect throttle response?

I thought I saw a video on Engineering explained, where he talks about this being an issue with mechanical waste gates.

 

The "just heard" can mean a lot of things, and a lot who spread anecdotal stuff about turbochargers in gasoline and smaller engines have old bad info or wrong assumptions. Of course some fail but modern iterations are designed better.

At this point we've got 5+ years with our turbocharged German car, and I'm near a year and 11-12,000 miles with the 4th gen Tacoma. From that experience I'm happy to take any risks associated with a turbo and especially for my at least annual while I'm at mountain elevations and the way you can operate a turbo in a frugal or powerful way.

The annual Consumer Reports auto issues are worth considering. They poll owners backwards 10 years. You can see vehicles with problematic drivetrains and gone ones.

 

I don't think there's enough difference to really tell. Power is pretty linear with this engine IMO.

 

Looks pretty easy peasy to me according to the manual, wouldn't be hard to make a manifold to adapt it to a different turbo either for those with the need for more power. Doubt under normal usage it would need replacement at any worrisome interval though, 200k easily with this kind of watercooled journal bearing unit.

 

Would the turbo theoretically have a lighter workload with the detuned 2.4? Or a heavier workload bc it (might be) more likely to boost with the lower hp setup? Forgive my fundamental misunderstanding of how this thing works

 

I had 187K On my Subaru WRX when I sold it, I never had to Replace the turbo And I drove the shit out of that car.

I think the Turbo on the Tacoma isnt somthing you need to worry about.

 

Theoretically, if every other part was the same, you’ll probably have lower cylinder pressures on the destined version.

but boost mapping isn’t always directly correlated like that.

but probably yes.

 

my guess is its all about the boost...
how do the 2 models compare in boost pressure at a specific speed, load, rpm...
No idea...

the sr is made to have less hp "de tuned" so dont see it making more boost...

 

Pretty sure the modern convention Toyota uses is actually based on torque modeling/targeting and it brings the boost up or down to meet desired torque target (with limits of course, it doesn't just let it run past pre determined safe manifold pressures) but its easier to make response more predictable for the driver this way with changing environment variables and such.

 

That was the Indy race from yesterday, the Nascar race was a few weeks ago both races were Road America, sponsored by AMR presumably the same crews and same support vehicles. I thought Road America was a track, I don't follow any motorsports that closely. No that Silverado is pulling what looks to be a Chevy in reverse as the crew is walking in that direction I think I saw about two minutes of a wreck yesterday.

 

I thought the Tacoma was only oil cooled for the turbo as it isn't putting out a lot of pressure compared to Tundra. I'm not sure about Ford but I'd think the 2.7 was water and oil cooled, and the 3.5 I put money on saying it water and oil. I keep an eye on the coolant in the reservoir, as it does not retain the bright yellow color of new coolant. Is it used coolant, is it coolant that got oil in it? Turbos do heat everything up epecially in tripple digit temps with high humidity.

Edit I think anyone towing with a gas turbo should drain and fill the coolant more than what's recommended.

 

The Tacoma is most definitely water cooled.

 

the blurb in the owners manual about letting it run for a minute after extended highway driving are bull. just in there to make grandpa happy. ive had my OR Iforce maxx go into auto stop coasting down an on ramp after 3 hours on the highway multiple times.

 

Do the hybrids have a sensor that prevents the engine from shutting down when decelerating/at a stop when the turbo is hot or does the electric water cooling take care of that?

 

I would've thought so being a modern design, maybe that's where the increased cooling comes from on SR5 and, SR probably still gets water cooling for the turbo but not as much. Maybe Tundra got some water cooling to assist with cooling the charged air, and I think that was an advantage on the cooling side that Ford does not have even on the 3.5
