4A-GZE Flywheels.

[mullett]

Noticed a distinct lack of these in the market, and I wanted one for my AW11. I'm in the process of designing and machining 4kg flywheels for the AW11, and maybe an aluminium pulley kit as well. Few questions about the flywheel:
1) Aluminium flywheel with steel ringgear and pressure surface: Can anyone see why this won't work? Different expansion rates etc...

2) Chrome-Moly (4140) flywheel: The whole thing machined out of one peice of 4140 billet. massive strength, but will have to be thinner than stock to get the weight down: Where should I take weight from?

3) Upstands. Due to the design, the GZE flywheel has upstands for the pressure plate to bolt to, rather than the pressure plate coming down around the clutch. Is there a pressure plate that can be used INSTEAD of the GZE one, which has the normal style upstands and will fit inside the standard bellhousing? Remember that I can move the bolt holes anywhere outside the clutch contact area....

4) Where can I get ringgears from? Toyota were supremely unhelpful, and no-one else can tell me for sure wether it's the same as the 4A-GE ringgear.

Oh...and does anyone want one?

has anybody tried lightened flywheels on gze motors? i red along the lines before doing my gze conversion that the flywheel needs to be a certain to stablise a motor like the gze?

can anybody correct me on that? i believe thats why theres no real aftermarket support. maybe im completely wrong but im pretty sure thats what i've heard!

maybe try talking to west brake + clutch their based in sydney. one of the best guys to get information and parts from try - www.citysearch.com.au

[mullett]

I'm not sure, I haven't heard anything. I just find that my motor isn't as snappy as I'd like it to be, so I'm going to reduce the weight of the ancillary shite...

If you go lightened you will find that it will commonly stall when you come quickly off the throttle. As the supercharger is still spinning and the lighter flywheel doesnt have the inertial momentum to keep the supercharger spinning and hence it stalls.

I.e. not reccomended. Try going a shorter intake tract, or a larger pulley instead.

[sw20r]

So I was correct :d

Nothing you can really do about making a GZE snappier.. Just the usual, Large 175-85mm pulley, remove aircon, convert to an electronic waterpump or you install some Highcomp pistons to really get zippy bottom end.

While a ZE may stall with a light flywheel when snapping the throttle off, I still think they are a good item (depending on the car's use). A lightened flywheel is a benefit, however as suggested above there are other ways to achieve better response on a ZE.

Try talking to Xtreme in Adelaide or Meridian Motrsport in Melbourne (who distribute for Alloy Race Components) about flywheels. Also bear in mind that you could use a 212mm flywheel with a custom plate to suit your box splines. May be easier to work it this way rather than totally redesign the 224mm flywheel.

To stop the thing stalling, just dab the throttle as revs drop. I did this for ages til I fixed my idle. Or if you have an aftermarket ECU, bump up the idle a little.

[mullett]

Yeah, keeping it idling shouldn't be too much of a problem. Or rig the SC trigger to a throttle switch, so it disengages when you are right off the throttle. Probabally worth doing anyway...
I've thought about using a GE flywheel and stuff, but it seems a regression...all that torque has to go somewhere, and a bigger contact area is good

Does anyone know about ring gears?

I looky looky on my epc, and i find that there is only one ring gear listed for the 4ag aw11s
13453-10010 1984-dec to 1989-dec gear, flywheel ring 4A#..AW11..MTM

A supercharger hardly loads the engine at idle, because you have shut the throttle, it is no longer compressing air. Compessing air is the 'work' part.

Have a dig around www.mr2oc.com, lots of aw11 4agze owners there. Most of the feedback on the flywheel is hugely positive to neutral.

[mullett]

So the lightweight flywheel has been done/is availible?

[c2888]

Search the mr2oc forums
you'll find that there isn't a 4agze lightweight flywheel
you'll find that you can use the 212mm one

oops, realised that you wanted wanted a 4agze specific one, my bad

[.T.]

actually there is an alloy 4agze flywheel available off the shelf from an overseas manufacturer. still easier to go back to a 200 or a 212mm type due to more pressure plate types being available.

the toyota ring-gear is one of the most expensive ring-gears on the market by the way

T

[mullett]

Yeah, I found a link to get those flywheels. Still very pricey, but on the upside it means that if they can do it, I can do it. I'm kind of wary about going down in flywheel size, you loose that extra leverage and clutch diam, which seems dodgy with the torque of the GZE. Does anyone know where to get ringgears to suit?

RM.

[.T.]

there is a much larger range of covers available for 200 & 212mm plates than there is for the s/c cover.

ring gear from aftermarket manufacturer are the same price as toyota. however any 4a ring gear is the same (ie 4ac will work - hint)

[mullett]

Just to dig up a dead thread...Does a T50 and an E51 have the same input splies: IE can I use a clutch setup from a rwd 4A setup in my GZE AW11?

Cheers, RM.

ive driven a 4agze aw11 with a lightweight trd flywheel and didnt have any troubles with stalling when snapping the throttle off however if you were to quick to get off the throttle i would jerk arround a bit but it was just something to get used to

edit: i really liked the response of the 4agze with the lightweight flywheel
