my 1jzgte engine (from soarer) with transmission finally come to my garage.
veryhappy.gif


so looks as I ended trying do something with 1uz-fe.
sorry.gif


after countless reading, thinking I am almost sure that 1uz fe is extremly hard to go with performance. That engine almost do everything to not modyfy it!!!. you try turbo it, you will end with drivebility problems cause no stand alone for that engine. Ignition is strange as strange ignition can be: two dizzies and two ignitors and no one who know what to do with that. You do more power? transmission will break very soon. want manual? it is pain i the a** route. Some guy in US TWO years try tubocharged it, some another trying more than TWO years manual transmission and no end is seeing.

Will be honest with you: I like chalenge a lot. But with 1uz there is no succesful stories. Everyone try do something and still try... and nothing.

I have enough that strange engine that is so strong and soo unsuported in performance parts. So I surrender.After all that 2 years I learned that engine do not like performance...
I have now 1jz gte engine.
now I can do something.
I wish you best luck with turbo/supercharging your 1uz engine.

Regards
Jerry
 
I think you must have been reading different posts to me.

Justen in Asutralia has been running his twin turbo with big horsepower for at least 18 months and it runs well.

There are dozens of modified cars putting out good power and being used regularly.

Yes the engine is a bit strange but considering you can buy the following off the shelf:

Pistons (high and low comp)
Rods
Head gaskets
Cams
ARP fasteners
Blower manifolds (and complete blower sets)
Individual throttle body setups.
Stand alone ECU's that run the engine no problem
Headers
Bigger valves and heavier springs
Plus some stuff I've forgotten about!

What more do you need to make one go a bit harder.

The 1JZ will make more power but it won't cost any less plus it will cost you to do the conversion.

I think we would all like to see a write up on the conversion as it won't be easy or cheap.
 
One our members JamesN just finished a 2jz swap into his SC400. I think the total cost was like $11,000 and almost 2-3 months down time. Now if he want to go faster... he will need to spend more money.... Dollar per dollar,,,, the 1uzfe do pretty well.

Indeed you have forgotten some stuff.

Bellhousings/adaptor plates to suit dozens of different gearbox's/transmissions.
Flywheels of different sizes/styles/weights.
Clutches to suit said flywheels.
 
don't forget you're stuck with a 2.5 liter engine.

to achieve 500HP you'll have to go big single turbo.

Big single turbo + 2.5 liter straight6 = lag

lag = no fun to drive

1UZ + M112 = 500HP, no lag, tons of fun.

I respect the 1JZ, I think you should redo your homeworks. I'm here from about 3 months and there's so much stuff about those engines that i don't ever know where to start! You want to know a Painful engine to modify? Try a Mazda KL series... that is pure PAIN.

as for the transmission, it's not because it's an automatic trans that i cannot hold the power. Go talk to 1JZ-747 on toyotacressida.net he's got an autobox and run in the 10's (built box, but still, no stock auto box can handle 500HP except old TH350/TH400 GM)
 
I not real sure what to say to that other than i have just ran a 12.3@112mph in a 1320kg car using a standard 1UZ & auto with 112 blower in full street trim & used 10.3l/100klms on the 350klm return drive home.
What more could you ask for????
 
anything is possible if u have money

maybe th emain reason the other jobs havnt been finished yet is money and time to spend on test and tuning

that type of stuff is not a 5 minute job

it can take ages

and also some people dont want to go aftermarket or there is no compitent tuner in the area

puttin twin turbos on a 1uz with a descent aftermarket ecu and a specially modified auto gbox should not be too much of a problem just long hard work and some spare cash i can spend money to do some small things to my 1uz but i can tbe bothered

its either std of full on twin turbo so maybe one day ill do it
its not money that stops me as most of the stuff with cost me nothing
 
There's just something about those turbo boys... ;-)

My IUZ would be under my mattress at night if it could.



Most know the turth.
 
sorry guys but that is only talking. I heared it gazillion times: put twin turbos to 1uz, put aftermarket ecu, put modded tranny and so WHAT? NOTHING!!! BIG VERY BIG NOTHING. That is truth about performance 1uzfe. BIG NOTHING.

someone making adaptor plate for very expensive and rare transmission? great !!!!for 700$???? GREAT!! two times more that engine hehehehhehehehheh. that lovely 1uz preformance world.

someone put ten-th times another then-th times another turbos/turbo configuration from lower to upper form left to right from twins to single turbo on 1uz and go to nowhere? GREAT!!!! THAT lovely 1uz

someone try (and trying just second year, when it will be silver anniversary of his trying I send him for FREE 1jz engine) put r154 to sc400? GREAT. where he is? NOWHERE!!! project was not ended. As almost all 1uz projects. normal in 1uz world

someone try put stand alone (megasquirt) to 1uz. where he is? is he ended project????

I lost two years and a lot of money to get short answer for my all performance needs: JZ

2.5 litre, 1.5 litre less that 1uz, and so what? with garrett gt35r ball bearing turbo I do not care if it have 4 or 2.5 litre. just boost and reliabe boost.

no v8 rumble from I6? and so what? I do not care about rumbling, bumbling and another mythos, I want to go somewhere fast and relable. that is not screaming chicken. it should be fast, not rumble bumble.

NOTHING beats engine that was factory prep for boosting. NOTHING.
why? cause we do not have millions dollars that spend toyota to find one or two things about turbo engine that we never ever will knows.

is there 1000$ engine that is making 400 hp from box as stock, just boost controler?
yes. that is 1jz.
is there 1000$ engine when you give more air (bigger single turbo) and more fuel (bigger injectors and controller) and have reliable 600 hp?
yes, that is 1jz engine.

I do not need anything more. that is reason why I putting 1jz in place where before was 1uz.
 
I have just spent about 6 months finishing my project. Now the 1uz has both manual gearbox, standalone ecu, and turbo. Didn't cost me much, but was a bit work. That about proves that you arr wrong in every point.

But most of the work was to make the engine fit in a Nissan. But of course, a 1jz is a much more supported engine in aftermarket parts. So if you do not have the time\knowledge to modify a 1uz, the 1 jz is a better engine to start with.

But why do you even care to write at this forum at all if you think the lexus v8's suck that much? We are not very interested in hearing about it.

Applications for 1JZ : Cars (I'd like to write race, but usually for race, ppl will swap a 2JZ)

Applications for 1UZ : N/A, Blown, Cars, trucks, boats, dirt cars, planes, race.

I think that explains a good part that everything you say about 1UZ is kinda crap.

How many group buys have been done here for blower manifolds, forged pistons, forged rods etc??? countless.

What your dear 1JZ has more than the stock 1UZ

1- Forged pistons and rods
2- Bigger injectors
3- huh... ok... maybe, ability to put 350BHP on stock turbos ? (wich stock, are not that much reliable)

so now, you need a fuel pump in the 1JZ, you also need in the 1UZ
you need a fuel management in the 1JZ, you also need in the 1UZ
you need a trans adaptor to fit R-154 in the 1JZ, you also need in the 1UZ

Stock 1JZ can handle 600BHP, stock 1UZ can handle 450. 150HP of difference. On a 600HP setup, it's not a piston set that will blow out your budget!

you need a fat intercooler on the 1JZ, you also need in the 1UZ
You need downpipe, blow off, etc on the 1JZ, you need a good set of headders on the 1UZ (for blower applications)

You need to spend money to swap, wire, buy engine, for the 1JZ. OMG!!!! the 1UZ is already in the engine bay! What a lucky guy! :blindfold (hey, how 'bout, since you save swap cost, this money goes directly on the piston set and rod sets. so now, you're head to head, money talking. you've got a 600BHP capable 1JZ, and a 1200+HP capable 1UZ)

Do I need to tell more? i don't think so.

Upgrading an engine will cost a lot of money, whatever is the engine. Some costs a little more, others costs a little less. But don,t say the 1UZ is Big Nothing.

You're talking the same way JZ guys talk about the old 7M, very arrogant, and that drives the sh** out of me. If you don't like the UZ, go away play Jeez with JZ guys.

I give 1uz fe some time and some money to try do something with that engine in my car. even fabricate lower support frame in my sc400 to put exhaust manifold to my single turbo. I have almost all parts that are needed to convert it to r154 manual too.

so I give that engine a lot of my work, time and money too. after that , after almost two years I assumed that I go to nowher. Go to 300 rwhp if I have BIG luck and a lot of trouble if I have no luck. I have 9 years ls400 too (celsior in au and japan). so yes I am quite familiar with with 1uz. Yes I was desperado to do FI in my sc400. I readed every post about performance upgrade on 1uz. I had straight path what to do and when.

But when I saw 1jz and I saw that for 400 hp I will need much trouble with 1uz, with 1jz: only boost controller. next stage: 600 hp is 1jz budget winner too. no need even open valve covers. I never wrote 1uz suck. It is best engine but hard to modyfy, much harder that jz that factory have turbos.

now to you 200sx-v8

WE are not interested? WE KING 200sx-v8 or just simple you? you talking YOUR opinion, unless YOU are king so for name yourself you can say: WE, we king 200sc-v8? yes?
wtf.gif

so stop bs me at that forum. my all posts was good, pure info, and that WAS same too. I just share my opinion and my experiences and my solution to people who are same as I interested with performance our v8 lexus. SO you are wrong, very wrong.

Perhaps there is someone for whom that topic help make decision: HOW make my car go faster???. Perhaps he chose not 1uz way. Let people themselves decide with way to go. If you could read more carefully you should see that my post was some kind of goodbye to 1uz community. I just want tell people why I leave that platform. perhaps there was people who recognize my and for them I made that post. It was not offence or anything. Just my opinion.

At the end of my post was best luck for everyone with performance mods to 1uz.


SO WE 200sc-v8 King should read better for future
 
TO uzz30:
1jz is capable more that 1000 hp on stock interials.
1jz have stock toyota bellhousing for r154 tranny.
1jz soarer is bolt on to my sc400 (soarer v8 in japan)
Plugs are bolt on too. BOLT-ON. two things not work: tacho and watertemp after swap. BOTH are easy cured to work. One more wire and one less wire to be precise.
plugs for body harnes are bolt on.
So stop say not truth.

Honesty I like 1uz, I have two cars with it. so I really like that small underpowered v8 engine.
in august 20 there will be swap day for me. I will honesty give you answer:

is 1000$ 1jz is worth be in 1uz place.

But if you not give me chance on that forum you still be in 1uz world: everyone talks no one work. perhaps you want learn more or just go hell for me cause not in love with 1uz.
as you wish
Jerry

There are MANY turbo 1uz's running around Australia, and MANY supercharged 1uz's.

One of them has well over 400rwhp now. The motor is unopened.
If he spent some dollars on the internals he would raise that figure dramatically.

No, Cowboy's adaptor plate was $700USD
In Aust you can get a bellhousing to match the R154 to the 1UZ for around $300USD.
RushImports are also doing an adaptor plate that I'd guess will come in under $200USD.

someone put ten-th times another then-th times another turbos/turbo configuration from lower to upper form left to right from twins to single turbo on 1uz and go to nowhere? GREAT!!!! THAT lovely 1uz

I have no idea what you just said

someone try (and trying just second year, when it will be silver anniversary of his trying I send him for FREE 1jz engine) put r154 to sc400? GREAT. where he is? NOWHERE!!! project was not ended. As almost all 1uz projects. normal in 1uz world
Click to expand...
Rush Imports owner has converted his on 1UZ Soarer to R154.
This kit is available 100% complete off the shelf now.
MANY people have do it before him, but no one has offered a kit before

Funnily enough this same car has been supercharged AND is running stand alone management.

someone try put stand alone (megasquirt) to 1uz. where he is? is he ended project????
Click to expand...
I can think of well over 20 people who have stand alone management on their 1UZ.
One of them is me. I've had it for almost 2 years.



At the end of the day its YOUR choice as to what you do with your car and your money. Just make sure you get your facts straight before you decide.

And remember, 4 litres plus boost will always make more power than 2.5L plus boost.
 
lol, 2-3 years ago, JZ guys were saying it could handle 600HP, now it's up to 1000!

Dude, to throw 1000HP of your 1JZ, you'll have to spend A LOT, LOT, LOT of money.

The little underpowered V8 is only 30HP less than stock underpowered little twin turbo straight 6.

BTW, it's not because someone made 1000HP on stock internals 1JZ on 1 Dyno run, than the engine can handle 1000HP all day long.

You're still stuck with a 2.5 liter engine that with a big turbo, won't give you an ounce of power under 4000RPM.

I respect your choice, but don't come here and say 1UZ is big nothing, I've never seen any 1JZ powered boats and planes.
