3sge Altezza Clutches & Flywheels

Ok, this post will contain info about the basics of the clutch/flywheel, but there will still be lots of detail and opinions in other posts.

Toyota used a dual-mass flywheel in the Altezza, just like Nissan and Subaru. These can get a mean shudder after a while, opening a window of opportunity to replace with a stock item, a single-piece same weight system, or a lightened single-piece for better performance. All single-piece items are aftermarket.

The stock clutch is a dual-mass flywheel. The one we replace it with is a solid disk of steel.

We think Toyota used a heavy flywheel to stop people stalling the car so easily, after all they don't have much torque! The dual-mass absorbs vibration in the driveline, as shown by the change in 3000rpm rumble when a solid flywheel is fitted.

We organised a group-buy with Exedy to take a dozen of their replacement single-piece flywheels off the production line and lighten them for us. They supply the high-performance clutch plates and pressure plates to fit those flywheels.

In the event, Manukau Toyota offered us TRD units at the same price, so we took the chance to get that TRD stamp on it! The specifications were identical. We have since made a second group-buy.

The retail for the TRD setup is less than stock dual-mass replacement and VIP members get a discount from the Auckland Toyota dealers as well. The actual price varies a lot due to the exchange rate.

So, if you want to replace one part of the stock unit, like the clutch plate, with something aftermarket, you will have to replace it all.

If you want to read about flywheel weights and what people think of the options, keep searching through the topics in this forum.

These are off Google images, and are not Altezza clutch plates.

However, the DM unit on the left does not have springs within the clutch plate to absorb transmission shock, whereas the conventional clutch using a solid flywheel on the right does. The DM unit relies on the springs and friction plates within the flywheel to do that.

Replaced my clutch this morning down at work, replaced with a lighter Single piece flywheel.

I took some photos of it all still bolted to the engine, and a photo of the slave cylinder (i remember someone wanted one a while ago). Will take some of the dual mass unit and clutch plate (well worn) and pressure plate on Monday if you would like that, as its still all on my bench.

Could you get some measurements, particularily from the seating face where it bolts to the crank to the ring gear and depth of the clutch etc

Looking at a cheap replacement and just wondering where the ring gear needs to sit and how much extra depth will need to be taken up by the clutch fork

Yeh should be able to aye.

Ill take some photos and get some measurements on Monday for you. And then ill draw it all up on paint on top of the photo or something aye.

What do you mean in terms of "depth of clutch" though? Thickness??

Yeah, how thick it is from end to end, like from the seating face on the crank to the seating face on the release bearing,

Cheers your a legend

I am contemplating a clutch upgrade soon. So I know I need a new clutch and flywheel but would like to confirm the exact parts I'll need. I don't want to be buying parts only to find they don't fit each other

will these do the job?

Exedy Heavy duty Altezza clutch - $520
lightweight flywheel - Toyota - Altezza 3S-G(SXE10) - 5kg - $598, or TRD one?

Is there anything else I'll need to buy to do the job properly? bearings etc??

Just make sure the clutch kit is suited for the Solid Flywheel.

That kit will include the HD Sports Tuff Cover but a factory disc, enough for your day to day foot work but if your car is going to hit a few track days or be looking into going forced induced, look into getting a puk clutch.

Ask Mac @ Fortyone via PM through here to see if he can do you a deal on the flywheel.

If you get stuck sourcing locally drop me a PM, I can help source Exedy kits (including flywheel) for cheap

i might just do that will talk about it at mm09 (no i won't be upgrading beforehand )

and not looking at turbos just yet... will be staying NA (unless i get bored, and rich)

so just jumping into the middle here i might be needing a clutch as d one i got revs me to 5000rpms at 30kph before shifting to 2nd....its not suppose to do that right? i know its not a stock clutch cuz i bought the car of an auction from mainland japan and it came with its stock clutch in the trunk? i got the turbo kit from apexi for it already...what should i do...should i switch it with the stock clutch get a new one or will the one i have be ok

I have no idea about cars and clutches and stuff so mine has slipped for a while and now gone. No idea what to replace it with or what I need to replace (flywheel and clutch???) I think it still has the original one. Would like your thoughts/opinions backed with reasons....

Such as Price, Durability, Racing/Normal. I would prefer to change the least as possible but cost isn't really an issue because I would in the end prefer quality over quantity.

The factory flywheel is a Dual Mass unit (aka not reuseable)

So either way your going to need these parts:
Flywheel
Clutch Disc
Clutch Cover (pressure plate)
Release Bearing
+ maybe flywheel bolts depending if your still torque up correctly.

As per the original post, the TRD kit is cheaper then the stock setup:

so whats a pretty good weight for a flywheel on a 3sge?

because ive found a 6.8kg flywheel for $350 but it seems still alittle to heavy for my liking (mind you im used to seeing 4age ones as low as 3.9ks)

would it be a good buy? not sure on brand but its made ni jap

6.8kg seems to be about right.

I know my JUN Ultra Light is just under 6kg.

Haven't driven the car, but that is about 1/2 the weight of the orginal, thats alot of rotating mass!!

Standard Dual Mass is about 12.5kg (without clutch)

so it'd probley be worth getting for 350 then

who knows what the OS ones weigh in at?

5.8kg.

All for 3SGE:

Stock Flywheel = 13.850KG
13450-74010/13450-74011/13450-74012

TRD Flywheel = 6.900KG
13451-TF100

Cusco Flywheel = 6.400KG
195-023-A

C-One Flywheel = 6.300KG
FF1340-SXE10

Jun Auto Flywheel = 6.400KG
2001M-T023

Jun Auto Ultra Light Flywheel = 5.900KG
2010M-T023

ORC = 5.400KG
ORC-010-05T
