The 1UZ-FE is one of the most reliable V8 engines ever made... it was ahead of its time.

Only thing you forgot to mention is that the first 1uz's were actually better for boost than the vvti versions, due to stronger rods.

I own an LS400 (87538 original miles) with a 1UZFE, and ironically it's the first engine that I have not modified and refuse to modify. I love how quiet the LS400 is, it allows me to escape the world while driving and just enjoy the ride. I modded a 1995 Camry by doing a 5SFE/3SGTE merge turning it into a stock boosted 5SGTE, and yet here I am with an engine far more capable and no desire to mod. That being said, the 1UZFE is an amazing piece of automotive engineering, when kept stock and maintained properly these engines are well known to go 1,000,000 miles which is insane, and they are one of the only automotive engines that is certified by the FAA to be used as an aircraft engine.

I have an 89 Celsior JDM in Australia, and its still going with no issues and no major engine or gearbox work that I know off (I've had it for a few years now) its done about 400K Km. Desperately needs panel and paint work, but still runs like a dream. With a quick fluids check, I would have no issue driving it across my country (4000Km) except part of Australia is still under lockdown.

I love my 1uz Soarer. I’ve owned; 2 Holden 5 litre V8s, a 400 Chev, an LS1 and an L98 6.0, a 302 Windsor, a 351 Cleveland and a couple of 360 Chryslers, I’m NOT a psycho but I accelerate flat out in 100 zones up to the speed limit multiple times every day, I’m simple and that’s what I love, So every motor I’ve owned has had rattly valves and been getting a tired after 60-80 thousand kays of this, Enjoyed them but all of them ran ragged and a few of them snapped EXCEPT my 1uz. I wring it’s little neck 4, 5, 6 times a day and after buying it with 80 thousand kays on it and putting another brutal 80 thousand kays on with daily thrashings, it is still a completely smooth, purring little kitten. Supernaturally smooth. SUCH a sweet little motor I love it.. It’s made me value strength and build quality over power. Haven’t had to shim the valves yet. Cool video man thanks!

Theres a class of speedway racing here in nz that uses the 1uzfe naturally aspirated with a single carb. Over 500 hp is achievable and upper rpm limits of 9k. Stock cranks billet rods and dry sump.

Man I have the LEXUS 2000 GS-400 with 113 000, and some miles on the engine, got it when this car only had 5 miles on the odominator still like NEW and this PUPPY still run like NEW, LOVE THIS VIDEO keep it up THANKS

Owned a '98 LS400 for a few years and still recall how awesome that V8 was. So ready to go, so quiet, and I could get better than 22 MPG _easily_. I got 27.5 MPG out of it on a purely highway road trip. All that from a car with almost 300 HP that weighed two tons! If it didn't require premium, I'd say it was the best V8 I've ever owned. I'm still considering sourcing one for a muscle car swap. That's what lead me to this video. Interesting learning more about that engine I so enjoyed.

Beautiful motor, great sound, good for swaps, strong and light, cheap to boost, flattest torque curve known to man, yet not too thirsty, easy to maintain... There's a reason the UZ series was put in all their trucks/SUVs and flagship sedans for two decades, and the UR that replaced it is essentially an evolution of the UZ design arc with dual VVT-i, direct injection, timing chain (yaaay), free flowing heads etc etc. UZ's are basically the LS of Japan, just the right combo of everything at the right time.

Had a 98 SC400. Loved that car, amazing machine.

You mentioned Valve Adjustments...I'm a Toyota MDT and have been with Toyota for 22 years. The only car that I have even had to adjust the valve spec on was a 2002 Avalon. Just 1 Intake Valve on #3. All of us in the shop were surprised because no one else ever had to adjust any valve on any of our engines with the Bucket design. I actually contacted Tech Support about this adjustment so they would be aware. The design is incredibly accurate. Hardened Chips as we call them, the little shim that goes on top of the bucket over the valve. These basically need no adjustment at all. Yes the Chips come in different thickness to adjust the gap but as I stated, they don't just go out of adjustment.

I had a 93 SC400 for 15 years, 170k miles and all I did was change the oil, it’s still out there…😊

Proud owner of a bone stock 1998 Lexus SC400 with 45,200 original miles on the clock. What a machine!

Who ever disliked the video got whooped by this engine. In his American v8

Good bit of info about these engines. The more research we do the more we know which version of the 1UZ to install in the project car. (:

Really good vid, solid info, clearly laid out. 👍🏾

First video and subscribed... good work 🤘🤙

Dont know about the later UZ motors, but the 1UZ also come with forged steel crank and 6 bolt mains (4 traditionally mounted plus 1 each side from the side of the block). This made the bottom end pretty bulletproof. Couple that with forged steel rods (thanks for reminding me @Jason Phillips) and specially constructed alloy/steel pistons and you have a really good base to start some serious tuning from.

Love the 1uz 👍

Great write up on this!

Good video on a GREAT engine.

I've got a modified sc400 with body kit, 22" nightrider mags, 5" exhaust system, Bluetooth and Saas sports steering wheel....etc. Ex show car, head turner.

Love my 92 ls400

Here to learn as much as I can to pick the best 1uz generation for my 450sl 1uz engine swap!

You said that for the 1uz needs a built bottom end to survive boost, and that they top out around 450 hp. Problem with this is that the 1uz can handle 600-700 on stock internals boosted...

Brilliant man thank you

How did it end up dying? No oil? It's very uncommon to hear a 1uz being killed. Even running boost through them. There is a stock ls400 with a million miles on it. Very interested how you went about killing the 1uz.

I want to put UZ on my Ford Sierra. Perhaps I will inflate it a bit with the help of a turbine and / or compressor. What model UZ can you recommend for such a task?

Sound's like a really great engine, The corolla was tough so you cant kill Toyota, Putting such an engine with a super charger in something as small as a civic hatchback would be blitz.

Toyota is f...ing awesome. They got it right so many times.

I would find a stand alone coil on plug set up if had $. We had a 92 SC400. Have to be careful with the square fuel rail, leaks! Also, parts are expensive! But when run right, with flow masters, yeah! JDM a lot cheaper on a budget rebuild. Also nice to have a manual car.

Hello buddy, can you please help me check whether I messed up my distributor rotor when I bumped my engine to enable me to remove the crankshaft bolt?

I was looking at getting a early 90's model ls400. Is the 1uz reliable enough to do lite mods and even a small amount of boost, or do I need to build the bottom end first. Looking make roughly 400hp. Not to familiar with this engine.

Thank you for the info:D

Will you help me out with my build please. I want to go with an Eaton M90... What intake manifold do I use? Please help me! What do I need to get this going. I'm picking out a the supercharger from a junkyard and so basically I need help with some step-by-step instructions.

Can you guide me how to get an modified engine for my ls 400 i wanna swap the original

I love this engine

Do you know what I'll need to swap this engine in a 2007 gs350 awd?

Best engine ever, I miss my LS.

Toyota Power!!💪

My mileage broke along time ago and it still runs great lol

U forgot to mention that 1uzs only came with auto trannsmission

I need a video on Sc400 jack points ..don’t wanna mess up any pinch welds

A video on the 2uz please!

Love your video. Where can i get the terminator cobra supercharger?

Early models of the 1uz had 4 cams as stated on the engine

it was the first version of the 1uzfe that had the more hd rods an pistons which no-one has noted an it is able to handle about 12-15psi depending on tune an with thicker head gasket able to handle more but ya limited to the cam an rpm's an the ports in the heads, but with custom porting, cams, valve job, blower pistons, cop ignition an aftermarket ecu, you can do 30psi+ @ over 9500rpm an make over 1500hp+

Just pulled a 99 1uz from a gs400!! Need a sick sleeper now to drop it in. 74 Corrolla??☺ Ideas???

I’ve allways use 98 RON fuel in my s180/majesta. Could I get away with 95 RON or lower eg (91 REGULAR) thanks :)

Please link me to the URL on your site with the article explaining the ways I can scoop up an LFA V10 for cheap from a JDM hearse or some crap

Which technology made this engine work so smooth and silent?

Factory 98 vvt-i with a 5-speed automatic is a great little fun dependable car

Can i use the 1uz itb on a 3uz? For a gs430 aristo.

Great engine :D I own one :) Greetings from Poland :)

Right the problem here is that a 1UZ-FE with thicker heasdgaskets a ringed block and stronger head studs could take 30 psi of boost and make up to 1000BHP without low compression pistons the 2UZ had thinner rods and the 3UZ was boared to 4.3 litres and thinner rods again and with the VVTI made it impossible to add power to it without major modifications

How does the 1uz-fe stand up the big boy 5.7L iforce V8?

Actually the 2003/2004 Mustang Cobra (Terminator) came with an Eaton M112 supercharger not the M90, which is a tad smaller than the M112 but still has that beautiful Eaton whine I love oh so much :-)

i want one in the future

Is it true you can swap the block with a newer v8 version block to get more power?

Did he talk about that it is or is not an Interference motor?

I was told they were factory balanced (weigh pistons etc )with 6 bolt mains because some models offered twin turbo...in Japan.

I'm sure I'm asking an extremely stupid question, but can you bolt on VVTi on the earlier engines?

Good vid, I've got a '95 LS400 second owner and only 55,300 miles on the clock from new . Certified. And, completely standard. No more power please, I like the silence, and the waft..

Just bought a 96' sc400 . does that have rhe 2nd gen or 1st gen 1uz. Its non vvti obviously

In your opinion are the engines in the 95-97 LS400 better than the 98-00 LS400???

Hey I own a 1998 ls400 I'm looking to add power but stay naturally aspirated what are some good mods I've been looking online and its pretty hard to find parts for this car

Is this guy sure about the bucket shims needing adjustment. Ive got 250k on mine, and did a bit of research, and everyone says they're known for not needing adjustment and being good to go for a long time.

Is the 1UZ’s piston heads weak?

Nice vid. I'm friends with the guy that owns the twin turboed 1uz you show in the video. The motor is in an AE86. He has since installed a twin turboed 3uz in it's place. I have a few uz swapped yotas and am now in the process of plling the 1uz motor to replace them with 3uz's. The vvti motors are so much better in NA form over the non vvti.

1:35 "also in the Celsior, Soarer...none of which we got in the US" Yeah, we did get them in the US: those two cars are called LS400 and SC400 respectively. Same car, different name for American market. Back then, lots of Japanese cars had different names because the American car buyer doesn't like wimpy (according to them) names like "Nissan Bluebird" (Maxima), "Nissan Gloria" (Infiniti M45), Honda Shuttle (Odyssey) etc etc... Actually in fairness, I should say that Americans like super masculine and powerful names because "Shuttle" isn't wimpy, it's just that Odyssey sounds mega-huge or something. :-)

Can anyone tell me if camshafts between the fe and vvti models are interchangeable?

can someone tell me from where i can buy loom plugs? if possiple kit. engine 1uzfe sora 40 40 40 ecu thanks

How much does this motor weigh, ready to run?

Are these engine same in the toyota FJ.?

330,000 on mine changed 2 water pumps and timing to stay up with maintanance. Oh and good luck to whoever has to change out the starter and one of these. Other than that my car is great

Need more videos 🙏

I’m not sure if your correct about the Toyota versions. I know the soarer came with a 1jz I’m pretty sure all the other version in Japan were the same but idk.

Hi. I have lexus ls 400 1995 with 1UZ-FE engine. Does it have interference engine or not? Thanks.

Million mile engine

Damn everyone is forgetting the Nissan vh45de. But love the 1uz

Later models had 2uz fe then 3uz fe then shit got crazy with the LS460 (since by then toyota stopped making sc only sc430 then that died off ) the LC500 looks fucken sick plust that 10 speed tranny have yet to see one on the road

How much horsepower does stock 1UZFE block can hold

Where i can find a supercharger fitted on 1uz?

i just got an sc400 with 350,000km and it feels a bit down on power, what are the first things i should replace/clean to get some of that power back?

I fixed 4.7 v8 Toyota engine in my old Nissan patrol.... It's amazing I can beat GMC Yukon.... Hehehe

What’s the difference between the Sc400 and the Ls400

“That 1UZ ultimately ended up dying” *Pauses for a moment of silence for his 92 sc400* I can tell you loved that car I’m sorry for your loss I had one too and I spun out and hit a tree 4 months ago at 140,000 stock too so I feel your pain. Holds memories like no other. Always thought the car having a phone was cool too haha

You should talk about the V8s that Toyota and Nissan are now producing.

I fitted a iuz in my Mercedes Sprinter van with w58 box best part was throwing the shitbox merc diesel in the shredder :D

quad cam* , great vid regardless

I would love to have a 4.0L VVT-i V8 swap. If I have another xB2.5, RWD, and a 5 speed or 6 speed MT. It be fun box

Review on the less known engine in Toyota's lineup.....1GZ-FE 5.0 V12

Vvti improved torque and fuel economy. Higher compression increased the power.

Can you talk about Yamaha engines, specifically the one's in the Taurus SHO models...

I run a 97 celsor non vvti in my FD rx7 with a 7500rpm its a total eargasm 😍 I spent sooo long on making the exhaust you can't even hear it idle but once you get on it she screams. I think my nabours don't like me tho 😁

Nice video. Check out Backyard Built. The guy's a Toyota wizard. He's currently finishing his second AE86. He also has a 1UZ video.

How to adjust noisy tappet on this engine

A wealth of information in this video, but im trying to figure out who makes a wiring harness to swap a 1uz into a 240.

Why doesn't someone sell turbo kits for the 1uz/3uz on ebay? I need a v8 manifold in order to fab up my kit. This is difficult. I can't make my own turbo manifold and I'm not paying a shop to do it. I wish it was just as easy as the turbo kits they sell for the 2jz. And on the eaton supercharger don't you have to have some kind of plenum adapter for it? I can't just bolt it on? Also will that even clear the hood? I think itb would be the less complicated route besides nitrous for big NA power.

What did you do to it?
