Lexus 4L V8 (1UZ)

Spartan · Post by **Spartan** » Sat May 15, 2010 1:54 pm

What type of weight do you have to look at for a good all-rounder fly wheel on the 1UZ, I see there is a few different types that are being made by various guys but which one, how heavy and do you go for aluminium or chrome-molly, what material to use?

Spartan · Post by **Spartan** » Sun May 16, 2010 1:48 pm

OK los dit dan as julle nie weet nie

maar kyk hier wat doen die manne

ek will net n lekker Lux met n V8 bou wat so bietjie korter is as die ander

kfxnando · Post by **kfxnando** » Sun May 16, 2010 2:58 pm

suppose depends on the application that you are after!!

self have a 17kg flywheel for the lexus V8, lots of local conversions are going with this weight!!

however my experience with flywheels is as follows!!
in a Sierra V6 3.4 Ford
had the flywheel cut, they took quiet a bit off, and robot to robot was a big difference!!
used to get a huge thrill of of upsetting the hot hatches robot to robot
motor had branches exhaust, two 38s a light weight flywheel and nothing else done to it!!
did not notice much of a difference between stock and cut flywheel and towing and not towing!!

My flywheel is a 26kg monster. 260mm big and I'm running a Dyna 3ton truck clutchkit. Budie of mine is running the std 22R flywheel. 235mm and light very light. His motor revs like a bat out of hell but he cannot even tow a venter trailer with it.

We tested mine, she can idle at 150rpm no problem and the torque is out of this world. She idles up everything, crawles like a big diesel truck.

On the V8, go as big and what you can. I got my stuff from Fana and it was well made, fits like glove.

A heavier and larger diameter flywheel will always slow down the rev climb rate of a motor, but the benefits are dramatic differences in low end power, improved power distribution through the rev range and even fuel consumption. Alu and light-weight fly-wheels are for the robot racers.

Castos · Post by **Castos** » Mon May 17, 2010 8:27 am

Jip thats so true. I'm still waiting for my BMC air filter, and then I want to get him dynoed at Schalk. At this stage I'm getting 8km/l on the open road cruising at 120km/h and in town it goes down to 6km/l.

Post by **Mud Dog** » Mon May 17, 2010 8:35 am

I'm sure you can get a lot better than that after the dyno and some toned down driving characteristics!

Castos · Post by **Castos** » Mon May 17, 2010 8:44 am

Ja nice to drive 'n Lux that sounds like a nascar.

Post by **Mud Dog** » Mon May 17, 2010 9:55 am

I'm sure! ... and I think that's why 90% of the guys with big motor conversions get poor fuel economy ..... You could probably idle that V8 through the gears right through to 5th!

oops!!

dont want to start anything, however if you got your flywheel from Fana, they you have a 17kg flywheels, the 26kg is for the whole set up, flywheels, clutch and pressure plate!!

Thanks mate, I have looked at what the V8 manne on their forum and they are using 10kg average. They are also using hydraulic through-out bearings which I think is great. Look at V-eight.com alto of interesting stuff

conversion man · Post by **conversion man** » Thu May 20, 2010 6:39 am

Spartan you must not always think the stuff over sea is so great .It took a south african to make the first helicpter that could make a loop . Al those fancy flywheels out of fancy materials are a lot ofcrap and a 10 kg flywheel is a pain I have tried them all in my own vans and like I have said before the only factory Lexus V8 manual runs a 28 kg fly wheel setup with a 300mm clutch . Every body is always keen on bigger brakes because thy work better so why go smaller on the size of the clutch ( just because it is cheaper ) ?. The diffs between the spin up of a light and a heavy flywheel is so small in the end but the smoothness of the extra inurtia gives a far more comfy ride and even more so when you 4x4 . That goes even for turbo motors as well as straight six engines , ask Alex he runs a heavy flywheel Imadeon a 2j and he realy 4x4 s .

Ok this is good info but where do you get a factory Lexus V8 flywheel and clutch and what box are they using

kfxnando · Post by **kfxnando** » Thu May 20, 2010 5:18 pm

this is what Fana is talking about

hope it helps going in the right direction!!

Spartan · Post by **Spartan** » Thu May 20, 2010 5:25 pm

I understand but as far as I know there was not one Lexus V8 that came with a manual gearbox, Why is everybody doing a after-market flywheel then:? :?

kfxnando · Post by **kfxnando** » Thu May 20, 2010 7:15 pm

look at the measurements on the 1st pic of three that I posted today!!

that width is an issue, and hence will become a problem with the bellhousing/gearboxes we use!!
have a closer look at the pics
here is the link to the pics, you can open them up to full sizes and have a better look at the tape measure!!
http://entertainment.webshots.com/album/577023371OpSSNZ" onclick="window.open(this.href);return false;

yes any thing can be made!!

then, think Fana posted it somewhere, that flywheel/clutch set will set you back around R14 000, cant remember where he posted it, here or somewhere else!!

Castos · Post by **Castos** » Fri May 21, 2010 1:09 pm

They are only available with the autobox and that is fitted with a torque converter. Fitting Fana's bellhousing etc is like getting factory fitted parts. believe me. .

O ja, got my BMC filter fitted inside the donaldson housing last night. WOW now I can feel the power. She runs like a bat out of hell now. 150km/h in 3rd gear running all the way like crap on steriods.

Man I love my Hilux now.

Gunta · Post by **Gunta** » Fri May 21, 2010 3:07 pm

Any idea what weight and size flywheel I should use on the 7mge. I am using the 4y flywheel and had to slot one of the bolt holes to fit the motor.

sorry the 3 pics that I posted together are of genuine toyota parts, think the motor came out of a cruiser or something!!

again that set up will set you back in the region of 14k, will go look for the info where Fana posted it!!

kfxnando · Post by **kfxnando** » Fri May 21, 2010 4:39 pm

here you go!!

this is what Fana said

by conversion man on Fri Mar 12, 2010 6:21 pm
The only factory manual LEXUS application is a kit consisting of a CAST BELLHOUSING flywheel and 300 MM clutch kit for use on the big ally landcruizer gearbox { I have one in my shop ] and that flywheel and clutch weighs 28.9 kg . THIS is a genuine TOYOTA kit but also costs in the reagone of R14000.00

conversion man · Post by **conversion man** » Fri May 21, 2010 6:14 pm

Gunta to start off it seems to me that there is a lot off (funny ) conversions out there . I will never dream of slotting the holes on a flywheel and then nogal a cast iron one I would rather make a propper new one . I would makeone for a 7m in the region of +_ 15 kg without the clutch maybe evenadash more becauseof the small 235 clutch .

Spartan · Post by **Spartan** » Fri May 21, 2010 8:07 pm

Why do you want to make a flywheel for a 7M when you buy it over the counter from Toyota

:? :?

Gunta · Post by **Gunta** » Sat May 22, 2010 10:53 am

when I did the coversion 6 years ago I could not get a 7m flywheel. The yanks were also doing it like this. I have not had any problems, but I was wondering what benefit I would get by changing it. Fana what would it cost to make?

Die OEM flywheel vir n 2JZ GE weeg dan net 8Kg sonder die clutch en die 7M GE ook, hoekom so swaar gaan :? :? :?

Al hierdie engines was bedoel vir pad karre met kleiner wieleas n bakkie endie gewig gee momentum .Ek het die storie van ligte flywheel al baie gesien en gehoor maar meeste ouens praat net , ek het dit self probeer op my eie voertuie en swaarder is better . Die bietjie wat die ligter een vinniger op spin is minimaal en die nadeel groter as enige voordeel so by so met n v8 het jy nie revs nodig nie want hy maak krag heeltyd ( by gese as hy manual is)

Dit is nou wat ek noem goeie inligting, hands-on, en weet waarvan jy praat

Ek wil die 1UZ met n R154 box doen, omdat dit n sterk box is, en het die addaptor tussen die box en die auto bell housing op die internet gekry, hulle verkoop tot die CNC program/design op ebay vir $25 dan kan jy dit maak. Kyk die foto

Fana, would a much heavier flywheel do anything on fuel consumption?

conversion man · Post by **conversion man** » Mon May 24, 2010 7:41 am

Spartan daai adaptor is baie mooi gemaak maar dan moet jy n concentric slave gebruik wat baie skaars en duur is hier by ons . Al daai fotos is van oorsee waar daai soort goed beskikbaar is dit sluit in n klein clutch wat die krag kan vashou soos die oorspronklikke 2jz clutch . Ook moet jy ont hou die shaft lengte verskil op die R154 box daarom het ek n housing ontwikkel en gecast wat die regte size LOCAL clutch kit kan gebruik en waar die gat vir die vurk reeds in is ( as jy die auto housing gebruik sonder n concentric slave SNY jy n gat in die housing wat hom verswak ) . en waar krake kan begin .

Spartan · Post by **Spartan** » Mon May 24, 2010 7:57 am

Ja hier is daai release bearings

conversion man · Post by **conversion man** » Mon May 24, 2010 8:04 am

Rian ek dink vir R3000.00 vir n flywheel en adaptor op n R154 box gaan jy in betaal want die shaft is baie langer as die gewone CRESIDA box . Maar miskien moet jy daai program op ebay koop sodat jy die gate se koordinate kan kry want iewers is jou jig wat jy gebruik skeef . Het een van daai ( adaptors ) gesien en die onderste dowel gate wou nie opline nie Ek sal hom gou more laat meet by NMISA .

Rian · Post by **Rian** » Tue May 25, 2010 9:08 pm

Sorry Fana.
Maar die vorm is darem seker eers ge-cast en dan ge-masjineer (cnc) net soos jou belhousings, dit moet darem seker 'n sekere vorm he voor mens dit kan masjineer (cnc) of hoe?

Ek is seker die manne sal verstaan waarvan ek gepraat het.

Ek verstaan die langer pilot shaft storie maar as jy by die ou gewone Cresida of Toyota bakkie boks bly is dit nie nodig nie, Ek het al gehoor daar is manne wat oorweeg om die goed langer te laat maak en dit is onodig. Ek dink maar aan die $$$$

conversion man · Post by **conversion man** » Tue May 25, 2010 9:23 pm

Just go for the auto and get it over with. Run the auto right and it will last. You guys go on about the auto being weak but how many of you have striped out a hilux box behind a V8....cumon be honest now. If you wanted to get your revs up there in a flash then you should rather go for the J series motor and not the V8, this thing of mine likes to be reved and those revs get up there fast, makes the old 4.0l V8 look like a granny mobile.

Why is it unfair the (old granny mobile ) is NON TURBO . but yes I think you are right because the AUTO has got no torque because the box consume all of it .Just as a matter of fact I do a lot of conversions and sell plenty bellhousings for conversions ( sold over 80 Lexus v8 bellhousings so far for the year ) and there was one gearbox (manual ) that packed up ( 4x4 ISUZU ) BUT I have also sold a lot of housings to guys who got gatvol of the auto and took it out because thy Do break ( had one and broke it twice ) .The RUMOUR of a Lexus v8 breaking a manual box started when guys who dont know how to fit a engine on a other gearbox started to do their own CHEAP CONVERSION .
