Land Cruiser V35A Engine

Conspicuously absent from that helpful under hood diagram was a transmission cooler.

 

Not surprised, especially on the suv

 

I am a bit surprised, Australian market customers frequently tow with their LC’s.

 

Maybe that’s what the electric fan is for in case the trans fluid starts getting too hot. It states “if equipped”. Is it an option for a trailer package?

 

Possible I guess, but there is no drawing of a cooler associated with that fan. It could also be a fan to move air over the condenser for the HVAC.

 

I lucked out before anything major went wrong. Had about 85k miles on it and the SMG gearbox started acting up so sold it quick (traded it in, along with an old Prius, towards a new 535xi around 2013) Was a fun car to drive but yeah they will get expensive to repair.

 

Good deal, got to enjoy it while it was still fun and then get rid of it.

Like dating a stripper.

 

I'm not given the way Toyota is going. It's obvious they can afford to cut some corners and still maintain a very respectful reliability level.

 

I suppose.

Plus they know what their transmission fluid can withstand for working temps. As synthetic fluids have gotten better and better the need to baby the fluids has lessened over time.

I will probably still put on a supplemental transmission cooler on my next Tundra should I buy one.

 

I agree. It's bullshit! Probably why I have a cooler on my 2020. Ridiculous that is not included!! But I'm gonna do what I have to do. Truck was $39K out the door....I can afford some mods

 

I think you're right, should have some decent tuning potential without a lot of hardware since the dyno plot you posted shows it is making power beyond 5200 RPM's and that means the turbochargers are not becoming a restriction too early in the rev range.

For guys that want to change out some parts, those radiators for the air to water intercooler could also be replaced with larger aftermarket units with larger capacity and more importantly more surface area to transfer heat. Assuming the Tundra will use the same set up, the giant grille on the 2022 makes some sense and maybe the air inlets under the headlights are there to force feed those radiators? More capacity to keep charge air cool and resist heat soak is not a bad thing even if you never turn up the boost.

At the very least a tune, intake(s), and maybe exhaust would be interesting. I suspect like most modern factory vehicles the stock exhaust isn't going to really rob that much power though. I would also be curious if turbo blankets would fit, and if so how much under hood temps could be lowered to keep everything happy while the truck is working hard.

Hopefully there will be more quality aftermarket support for this engine than the 3UR-FE has. Too bad Toyota probably won't enjoy economies of scale with this engine and cram it in every engine bay that it can fit in and still be serviced. If they would there would be lots of good aftermarket parts for the V35A-FTS. Top of the line Tacoma and 4Runner for example should be able to get the V35A-FTS as an optional engine, they should put it in the next Lexus GX at the very least if they don't allow the 4Runner to have it. Any of the RWD architecture Lexus sedans should get a variant as an optional engine.

 

Not sure if there is a trans temp gauge on current tundra’s. If not, do we know there is an issue with the trans getting to hot? And, maybe the 2022 radiator has more then enough capacity to keep the trans fluid cooled off.

 

For fuck’s sake, the truck’s not even being made yet and folks are already complaining about no transmission cooler.

 

Folks complaining about something new?

 

2 airboxes
2 air filters
2 maf sensors
2 throttle bodies
2 turbos
2 intercoolers
2 map sensors (assuming)

 

Some more details on the Land Cruiser 300 and probably Tundra spec V35A-FTS ‘21 Variant:

https://toyota-club.net/files/faq/19-09-10_faq_df_v6_eng.htm

Differences between the ‘21 truck/suv version and ‘17 LS500 that I was able to pick up on:

1.) Cam timing on the ‘21 intake cam is hydraulic instead of electronic as on the ‘17. Probably more simple and less costly to produce. Being hydraulic ‘2022 owners will of course need to stay on top of oil changes, but that’s nothing new for any vehicle with hydraulic cam timing adjustment.

2.) Cam phasing for the intake cams of the ‘17 is up to 85 degrees where the ‘21 is only 65 degrees. Exhaust cam phasing is identical on both at 44 degrees.

3.) Oil pan is different on the ‘21 than the 2 versions on the ‘17.

4.) Wonder of wonders the ‘21 uses a spin on oil filter! Hooray Toyota please make sure the Tundra also gets a spin on.

5.) Piston oil squirters on the ‘21 are simplified compared to the ‘17.

6.) The ‘21 uses a single throttle body and a single intercooler on a single piece intake manifold. My guess is the more generous vertical space under the hood of the Land Cruiser vs LS500 allows for a simpler and larger single intercooler to do the job. Plus it’s probably less expensive to produce.

7.) The ‘21 uses a belt driven clutched cooling fan instead of the electrical fan of the ‘17.

8.) The ‘21 uses two accessory belts instead of one on the ‘17.

Probably some things I missed. Enjoy.

 

Did enjoy, thanks. I suppose having experience in the Lexus for a few years Toyota learned some things. They put it in the Land Cruiser so that shows confidence, LC is something they don't want to f up.

Every Lexus/LC V35A has been built in Japan, I guess the Tundra/Sequoia V35A will be built in the Alabama engine plant, hopefully they have that workforce trained and ready to go.

 

If its anything like the Ecoboost then those are not maf sensors. The Ecoboost is speed density tuned, meaning it relies on the manifold pressure and some volumetric efficiency calculations done within the PCM to calculate the air flow into the motor. It then has factory wideband O2 sensors to run it in closed-loop mode and keep the AFR's exactly where it wants. The sensors by the intakes could just be pressure/temperature sensors.

Since the engine is a twin turbo V6, I actually really like the dual intakes. It gets rid of some extra tubing and stuff that has to cross over the motor and probably makes it a lot easier to work on.

 

If I had to guess, its more like:

2 air filters
0 maf sensors
1 throttle bodies
2 turbos
1 intercooler
1 map sensors
1 TIP sensor

The intercooler is probably split up to two exchangers on the LC due to size of the truck. i bet they could use a single unit on the Tundra with that gargantuan grille.

 

Is there any fuel mileage info out on the land cruiser yet?

 

I’ve looked but didn’t find anything.

 

Had to download a brochure from the Toyota of the United Arab Emirates….

 

So…. 9.3 km/L = 21.87 MPG.

Since there is only one rating and I have no idea if that is city, highway, mixed driving cycle it’s hard to translate into mileage we can easily quantify by our standards.

The fuel tank is 110L = 29.05 gallon fuel tank.

So if we *assume* the fuel consumption listed is per Japanese testing standards which include a mixed driving cycle that combination could yield a range just over 600 miles on a tank of refined dead dinosaurs. Figure a real world range of 500 miles before the fuel light comes on.

 

Best sounding motor BMW has ever made imo but also one of their biggest POS lol.

 

Best sounding BMW motor? I’ll give that honor to the BMW V12 built for the McClaren F1.

 

Looks like the V6 layout in my 350Z. Battery is under passenger side cover and brake & clutch fluid on driver side.

 

Looks like my Q60:

 

29g tank is pretty good. If Toyota can get that into a shorter wheelbase, narrower vehicle on the scalable TNGA-F platform that seems to point to a 29g+ base tank for Tundra/Sequoia. I researched the Ford Ecoboosts MPG towing and found it's less than the 5.7l on the same hill, the same trailer, on the same day (TFL Ike Gauntlet). Never owned a Ford TTV6 but I've read enough people say you get either Eco or Boost to think the V35A will be the same. So a larger stock tank will be nice for towing range. Looking at fuelly.com Ecoboost owners are up into the 18-20mpg range consistently.

 

Its good to see some new changes, its inevitable, you have to change or make no money in the car business and its good to see new engine with more power and torque. My only complaint with the new 300 series landcruiser is they took away the split tailgate, that was a unique feature, its only one solid piece that opens upward like most SUVs.

 

Sure if memory serves the EcoBoost was also considerably faster up the hill than the Tundra too. I’ll take power over fuel economy 99% of the time thank you.

The run with the Ford 3.5L EcoBoost up the Ike: 8:02 seconds, with quote "the ability to accelerate at any time". Also 3.5 MPG.

The latest Tundra run up the Ike: 8:13 seconds with the pedal buried to the carpet…. and 3.4 MPG.

Can you say ass whipping? ‘Cause the Tundra 5.7L is getting it’s ass whipped in the mountains. Also beat by the basic bitch 5.3L GM V8 and 10 speed combo on the same day.
