WTB: Lightweight flywheel

[clint111]

I know I can get it from rpw, prob also from ebay sellers.
Anyone happen to have one up for grabs, I think the fidanza alloy one is part number 161111?

Alternatively, could anyone tell me if the part 161731 will fit/work?
A bit of reading/browsing leads me to understand some parts are interchangeable with certain EVO's (which ones share the flywheel/clutch), also the 6A13TT motors?

I do not think anyone here has the flywheel.

Toda makes a lightweight flywheel for the 4G92 and from what I understand you can use that so long as you also use a 4G92 clutch

[Bennoz]

I had the Fidanza one

[clint111]

Ok, so flywheel and clutch for 4G92 are compatible?
Anything else? 4G63?

[spetz]

It is compatible so long as you use the 4G92 clutch as well.

How much power are you expecting to make?
You can get an RPW flywheel too (rpw.com.au)

[clint111]

Power expectations.. lead to disappointments..
It will make what it makes. Not sure yet whether I go sc or not.
Will get it into the car, then assess what room I have for either roots type or centrifugal sc, and decide whether to run one, or just stay na.

The toda flywheel and clutch kit works out around $1200aud. Not bad at all.

The 4G92 flywheel/clutch is a bit smaller and of what I've heard handles less power.
I have an Exedy HD clutch and couldn't be happier with it for what it's worth

The limited research I did on this is that there is no direct option for the 6A12 Mivec, but there is one that's very close that requires a little machining, which is what you get from RPW. Can't remember all the details but a Google will fill in the blanks

[clint111]

An email to/from rpw has the owner claiming that the fidanza flywheel they offer is in fact a direct fit.
I can't see it helping his reputation if he is misleading potential customers in order to secure a sale?

[spetz]

It should be a direct fit. If it needs machining etc to fit RPW would have done this before selling it on

[Bennoz]

They do ^

The also supply the longer bolts needed for it. Fidanza do not list an FTO specific unit, its a Galant or Evo unit slightly modified by RPW. As mentioned, I had one & it bolted on fine. Its actually quite a good product & to my way of thinking reasonably priced. Only issue I had was it took a month of Sundays to arrive.

[spetz]

Bennoz did you have yours installed on the 6A12 or 13?

[Bennoz]

On the 12

Yep as others said, it's a Fidanza flywheel that RPW modify to fit the FTO. If you google hard enough you'll find more info, but yeah for the price it's not worth doing yourself imo. This is one item from RPW that is actually reasonably priced

Can you comment on the differences felt? Acceleration? Rpm drop? Easier/harder to drive? etc etc

Standard sort of light flywheel feel. Motor spun up quicker, acceleration was better, did did suffer a slight loss in low down torque. Ie going up a hill in 5th became going up a hill in 4th.

There were 2 types of that Fidanza flywheel available, a street use one (the one i got) and the track one. To my way of thinking the track one was too light for street use. Would have made cruising around town a bit of a pain.

I also went the other way when doing the manual conversion to the misses car. I milled about 1.75kg off a standard flywheel. Feels almost the same as the Fidanza one in my old motor.

Just adding to Ben's comment here, if you're going to mill an existing flywheel, make sure it's done professionally and balanced. There are a few youtube clips around of modified stock flywheels exploding at full revs. You can imagine the carnage

[Bennoz]

Yeah... that & poorly done flywheel ring gears are a killer. Most of my old mans mini racing mates are missing little toes on their left feet thanks to that!

[Shane001]

There's a vid of a big horsepower doof doof Supra on youtube somewhere giving it a big rev and the whole thing just lets go, tears the floor to bits, very lucky not to loose his legs

What a dangerous game we play
