Transcripts

what is a boys and girls welcome back to

iconic engines today we're covering our

first ever v8 engine with an iconic

engines and we are starting off with

some aluminum quad cam 2 Yoda muscle of

course I'm talking about the 1 uz f II

and I'm gonna be pronouncing that as

booze for the rest of the video because

it makes it easier than to spell the

whole thing every time and I will be

repeating the engine name many times

throughout this video also I want to let

you know that this is our fifth video

has been made possible by a and as you

already know AEM are the top dogs when

it comes to aftermarket performance

electronics doesn't matter if you're a

car enthusiast a professional tuner or a

full-on motorsport racing team AEM has

the electronics to take your bill to the

stratosphere so if you need some

top-notch stuff that has been engineered

to outperform definitely check out this

video's description because there you

can find the links to amazing AEM

digital dash displays ECU's fuel pumps

and more also last time thanks to AEM I

was able to invest in some audio

equipment and improve the audio in the

iconic engines video series this time

again thanks to a.m. I was able to

invest in some lighting equipment boom

let there be light

so the one earth engine was that's just

stupid whose idea was that the what you

see engine made its debut in 1989 in the

engine bay of the Lexus ls400 the car

that basically made the Lexus brand but

to compact the de bureau of this engine

into this one single sentence that sort

of makes it sound like it just popped

out of nowhere in 1989 would be a

massive insult to a relentless pursuit

of quality that started six years before

with Project f1 now f1 has nothing to do

with Formula One it was a secret to Yoda

project and f1 stood for flagship sedan

number one and this was a project

initiated in 1983 by none other than to

Yoda chairman himself mr. Eiji Toyoda

the goal of Project f1 was to make a

luxury sedan that would rival and outdo

flagship vehicles offered by American

and European brands and to make this

happen to Yoda went all in the f1

project had no budget and had no time

constraint basically Toyota was willing

to spend everything it took to make this

happen and to make it happen to your

head 600 designers 1,400 engineers 2,300

technicians and 200 supporting staff

working on the f1 project basically

that's a medium-sized village of Toyota

employees making this happen

but the number of people isn't what's

impressive what's impressive is what

these people did now chief engineer

Ichiro Suzuki who surprisingly wasn't a

very obvious spy for Suzuki was leading

a team of designers and engineers that

over the course of Project f1 developed

450 B

prototypes and 900 engine prototypes one

of those engine prototypes that came on

top was the one you see and once

engineers settled on an engine design

they decided to celebrate the new engine

by putting it through help development

teams on the f1 project clocked more

than 2.7 million kilometers driving the

LS 400 prototypes with one new zfe

engines in them everywhere from the

Nordic regions of Europe to the

scorching Sun and sand of the deserts in

Saudi Arabia 2.7 million kilometers

that's actually enough to go from United

States coast to coast

more than 650 times designs of them

ls400

and the one you see Fe were reviewed

countless times something that many

other manufacturers would find totally

acceptable was reviewed again and again

and improved until it was basically

perfect so there really is no surprise

factor to the fact that the LS 400 and

the 1uz fe engine is one of the most

reliable toyota products ever made it's

actually one of the most reliable

automotive products ever made in 2007

the LS 400 made Consumer Reports a list

of recommended vehicles that regularly

do more than 200,000 miles but now it's

2020 and many owners around the world

who actually proven that the 1uz fe

engine can do twice that easily with

nothing but regular maintenance by the

time the f1 project was finished and the

receipts tallied up to Yoda had spent

more than 1 billion dollars to make the

LS 400 happen but it was all worth it

when the LS 400 hit the market it was

quieter it was faster he had a lower

coefficient

drag it had better fuel economy and to

top it all off it was cheaper than all

of its competitors the secret was out

and everybody was dumbstruck now this is

not a test we normally perform on Top

Gear but it's a perfect illustration of

the Lexus engine I can put a glass of

water on top of the unit and at idle

there isn't even a disturbance in the

surface better still I can have the

engine revved to 6,000 rpm

and as you can see the water doesn't

even tremble now that's not something

you can do with the other three rivals

Toyota tell us they had a team of 60

engineers working on noise vibration and

harshness and the results speak for

themselves but when you see was a very

ambitious engine after head impress the

land dwellers with its lightweight and

compact design amazing smoothness and

power and reliability the 1uz wanted

more in wanted to fly the 1uz is

actually one of the very very few

automotive engines that was given

production certification and approval to

be used in airplanes by the United

States Federal Aviation Administration

in its airplane form the one you see is

called the FV 2400 to TC and it's a

twin-turbo 360 horsepower engine pretty

cool right so after flying the one you

see decided didn't wanted to swim and

swim it did as well it actually ended up

in some Toyota boats talk about smooth

sailing with a very smooth v8

[Music]

after that swimming and flying the 1uz

decided that it wanted to save life's

too and save life's it did as well it

actually ended up in the engine bay of

the toyota hiace high Matic ambulance

van which is pretty cool even if you

don't make it at least you dive in a

aluminum v8 quad-cam 32-valve powered

ambulance man

so after flying swimming and being a

paramedic there was just one thing left

on the one you zis bucket list and it

was racing to race the 1uz ended up in

the engine bay of the Sartre MC 8r

where it developed 600 horsepower in

twin turbocharged form

sadly though the 1uz wasn't a great

success in the Oman the MC 8 R really

couldn't keep up with the likes of the

Porsche 911 gt1 and the most notable

result it did in my mom was finishing

second to last which is kind of bad I

had a man on his right is well on fire

it's one of the saw Toyotas it's Tatsuya

Tanigawa trying to get back to the pits

but that car is well aflame but even

though it wasn't a great hit in a month

today car enthusiasts have discovered

the amazing potential of the 1uz engine

being a lightweight and being compact

and being a v8 makes it an amazing swap

into pretty much everything and today

enthusiasts are swapping the one you see

in two cars that are much lighter and

much more nimble than the LS 400 where

the 1uz originated and now you can see

one use these kicking ass on everything

from the drag strip to drift events to

circuit racing

so let's start what we always start with

when it comes to the engine specs bore

and Stroke when it comes to the 1uz we

have eighty seven point five millimeters

of bore and eighty two point five

millimeters of stroke which gives us a

pretty over square engine design and

having eight Sanders it also means that

we have a pretty healthy engine

displacement of four or either's as you

already know the one you see is an all

aluminum design which means we have an

aluminum engine block and aluminum

cylinder heads when it comes to the

block we have a ninety degree angle

between the cylinder banks inside the

engine block you are going to find a

forged steel crankshaft with eight

counterweights this is pretty neat as

usually on mass production v8 engine

starting to find six count rates we have

another pretty cool thing in the

aluminum engine block and that's six

bolt cross bolted main bearing caps on

top of the main bearing cap you find

these four bolts but on the sides there

are two additional bolts that both the

side of the main bearing cap to the

block this the crankshaft and the

oversquare engine design actually make

the one UCF York like a racing engine

and this was something that was

confirmed by a statement in 2007 from

David Courier who was president of TRD

USA then and he said that the one you

see EFI engine design was actually based

on an Indy Racing League engine design

and that they were plans to use the one

you see in the gt500 racing series the

connecting rods are made from sintered

forged steel the Pistons use a hyper

eutectic aluminum alloy with additional

steel struts that help control the

thermal expansion also the business

skirts have been finely grooved to help

a better lubrication and reduce

frictional losses moving from the engine

block to the cylinder head the letter F

in one use EF e becomes apparent as you

might

already know F stands for economy

oriented cylinder heads in Toyota engine

codes while G stands for performance

oriented cylinder heads such as for

example in the for a GE or the 3sg e

while the cylinder heads of the one you

see Fe definitely aren't bad they aren't

as outright performance oriented as you

might think they would be when working

at that motor sporty engine block so

what do the cylinder heads have they do

have a pent roof combustion chamber with

good squish areas and a spark plug in

the middle they also do have two

camshafts person cylinder head giving us

a quad cam engine design however only

the intake camshaft is driven by the

timing belt the exhaust cam is driven by

the intake camp via a gear between the

two camshafts the valve included angle

which is the angle between the valves

themselves is pretty narrow and economy

oriented in the 1uz engine and it sits

at 22 degrees and 33 minutes when it

comes to the valve sizes we have some

pretty average valve sizes of thirty

three and a half millimeters from the

intake valves and 28 millimeters on the

exhaust valves the camshaft profiles are

also expected relatively conservative

and we have some pretty mild duration

and lift on both the intake and exhaust

in its original form the 1uz engine

makes 256 horsepower and has a pretty

nice 353 Newton meters of torque it also

has a compression ratio of 10 to 1

now the one you see received revisions

in the 894 and in 97 both of these times

a lot of little things were redesigned

and improved upon but the big ones to

mention are in 94 the compression was

increased to ten point four and this

resulted in increased power output of

261 horsepower but 97 was the big one

and this is when the uz received

variable valve timing actually Toyota's

vvt-i and another small bump in

compression to ten point five of this

resulted in the final power output of

290 horsepower with the prices of

popular big swap engines like the two

Jay Z or the RB skyrocketing the 1uz is

actually a breath of fresh air on the

tuning scene it's a v8 that's compact so

you can swap it in two cars that are

much smaller and lighter than the Lexus

and Toyota cars that the 1uz originally

came with but it also has a good bottom

end and great power potential I mean

what's not to like

it's also becoming an ever more popular

swap into the Toyota gt86 /b RG / FRS

and even some supras are foregoing the

traditional one jay-z - jay-z route and

are instead stuffing in one uz into

their engine bay so swapping in one uz

into something else is going to be our

stage 0 basically find a nice clean

alone mileage 1uz and stuff it into the

engine bay of whatever you want now when

doing this most one use these do come

from Japan or have an unknown history so

you have no idea what are the actual

miles other than somebody telling you

what are the miles so definitely

definitely consider doing the basic

servicing replace the timing belt

replace some gaskets do an oil flush and

all that you know to ensure that your

new old engine is fresh and ready to be

enjoyed when it comes to choosing a want

to use these to swap into something if

you aren't planning on extensively

modifying your engine or adding forced

induction actually the later one use

these are the ones after 1997 that have

variable valve timing and an increasing

compression are the most enjoyable to

drive in stock form on the street and

you make the most power the one you see

of

works great for drifting I know to Yoda

I never thought about drifting when they

were designing the 1uz but to leave it

to car enthusiasts give us an engine and

we'll do everything the manufacturer

never intended to do with it I mean

that's what makes us cool right so what

do you see and drifting now the one you

see has a smooth linear power delivery

and it also has a pretty healthy amount

of torque combine that with a

lightweight rear-wheel drive chassis and

maintaining long smooth beautiful drifts

becomes a joy with a one use the engine

[Music]

[Applause]

[Music]

[Applause]

but let's say you want more power you're

not satisfied with the stock power

output how do you get more power well

the first thing in your way is actually

the ECU don't do anything else until you

get a tunable standalone ECU as you

might know to Yoda ECU's can be chipped

or hacked into so there's no way of

modifying the existing issue and you

have to get a stand on but once you get

a stand on for it 1uz you're gonna open

many many doors for yourself because all

the other mods that you add on to it

later are gonna make the most you know

they can with a standalone ECU after

you've done the ECU you can start by

getting rid of those stock economy

oriented exhaust manifolds and replacing

them with more performance-oriented ones

there are off-the-shelf aftermarket

solutions for exhaust manifolds on a 1u

z but depending on what you're swapping

the 1uz into you might be forced to make

some custom ones on the intake side of

things if you have an older 1u z fe

engine the aftermarket ECU is actually

going to allow you to get rid of the

stock restrictive air for meter and do a

cold air intake of these mods for stage

one aren't going to yield around 15 to

25 extra horses for you for stage two we

are going to tackle the cylinder heads

now let's sell the heads of the 1uz with

their narrow encoded valve angle and

their port design are actually probably

the one of the most limiting factors

when it comes to performance on the 1uz

engine but while you can't redesign the

cylinder head and replace it for they

don't do a different one you can tackle

the camshafts and the valve angles and

other stuff you can get some aggressive

cams and replace the stock mild camshaft

profiles you can upgrade the valve

springs and you can also have some more

performance oriented valve angle Scott

after that you can port and polish

the cylinder heads and then you're

looking at additional maybe 20 to 30

horsepower depending on the camshaft

profile you go for always when it comes

to camshaft profiles don't forget

massive power gains in the top range

almost always come at the expense of

fossils in the bottom end of the rpm

range our standalone ECU is also going

to enable us to get rid of the factory

intake and replace it with some

individual throttle bodies how about two

sets of ITBS

from the for eg 20 valves going to give

us an extra sharp throttle response an

amazing soundtrack and an additional 10

to 15 horses

[Applause]

[Applause]

now naturally aspirated tuning beyond

this point actually becomes ever more

expensive with ever decreasing rewards

because you really can't overcome the

design of the stock cylinder heads but

what you can do is force induction turbo

supercharger nitrous the 1uz has a

pretty good bottom end and it has proven

itself and being pretty good at coping

with forced induction

when it comes to choosing a 1uz engine

to use for forced induction we're gonna

do the opposite of what we did when we

were talking about a stock swap we

actually want the early engines for

forced induction and those are all

engines made in 1994 and before these

are better for boost because they are

over engineered a bit compared to other

engines they have thicker and beefier

internals however it is early Gen 1 uses

are becoming ever harder to find so many

people settle for the later engines and

upgrade the Pistons and conrad's when it

comes to safe boosted power levels for

the stock back of the one you see all

generations can take safely apt around

450 horsepower however many people have

pushed the stock first-generation

internals to well above 500 horsepower

so we can assume a safe power level for

the first gen to be around 550

horsepower let's say but all of these

safe power levels are just an estimate

and they should be taken with a grain of

salt like a huge giant this is big grain

of rock salt and you can keep this big

grain of rock salt on the side so you

can smash it over your head when a

horrible - kills your engine at power

levels well below those deemed as safe I

always repeat this in my videos safe

power levels assume a good tune they

assume not monitoring and other safety

measures that save your engine's life a

horrible - based on guesswork is gonna

ruin an engine way below safe power

levels when it comes to turbos you have

the option of going for a big single

turbo or doing twin turbos the V

configuration is really asking for twin

turbos and there are a lot of really

good 1uz twin turbo belts out there

[Music]

however the aftermarket

in general is still lagging behind when

it comes today 1uz and it isn't even

comparable to more popular engine

platforms and while the aftermarket is

catching up recently

you still will need to do custom stuff

probably when it comes to more serious

tuning off the 1uz when it comes to

super charging super charging is also

really popular and it works well with

this engine when it comes to

superchargers many people use the m90

from Eaton or the Terminator Cobra

supercharger although others have been

used as well expected power levels are

with a basic supercharger conversion you

can expect first expect around 350

horsepower with supporting mods and the

roller compression forged pistons you

can look at around four hundred and four

20 maybe 430 horsepower at around 10 to

11 psi

when it comes to nitrous the situation

is pretty similar as with turbos if you

upgrade your Pistons and rods the sky

really becomes the limit and 600 700 800

horsepower one use efe builds our

unclearly that uncommon anymore

engine hope you enjoy that hope you

found it useful informative and yeah now

it's time to end the video with what we

always end the video and that is rap and

this time it's in Japanese no I don't

speak Japanese I did go to a basic

course and I did get a basic elementary

level certificate which enables me to

order a drink at a restaurant and say hi

and goodbye

they definitely did teach us how to rap

but I dug my own grave by saying

challenge accepted to a Japanese rap

idea in the comment section and I just

spent the last hour and a half on Google

Translate trying to figure out how to do

this and it's probably gonna be horrible

and full of grammar mistakes but I

didn't myself so it's two days boku wa
