how much does the standard r33 flywheel weigh?

[MicK51]

12kg?

[MrMayhem]

i wieghed mine earlier at 10.8kg but we're talking shower scales

[skyzerr33]

gotta lighten ones at 4.8kgs

[MrMayhem]

most of teh aftermarket jap ones are 5odd

i wighed my hks moly one at 4.8 also

[skyzerr33]

yeah its one of the next things on my shopping list

I had mine (R33) done through Tim at Horsepowerinabox.com, the factory weighs around 9.1kg and my new stainless steel (chrome moly) weighs 5.9kg, much better throttle reponse now and it really whipps up to the redline in the first three gears. So those HKS versions are super light for sure!

MrMayhem, do you have idle problems with the HKS flywheel?

[rev210]

Stock is 9.8kgs on an R33 RB25det.

Most aftermarket ones are 6/7kgs or under.

The Ogura I have is 4.8kgs. Structurally the chrome molly units are 200% stronger than an un-lightened stock unit and with less intertia they spool your turbo like a bastard!

No - idle problems. smooth as stock.

No - gear change problems, shifts easier/quicker

No - loss of revs between gears, not noticable due to faster shifts.

Revs quicker

Boosts quicker

Goes quicker

Idles perfect.....

cheers

Ok im interested, i'd love 1/2/3 gears to be smoother.

What are the costs involved ? Can you show me an urls of pics/info/shops etc

[MrMayhem]

jap brands are bulk expensive $900

but....

an autralian brand is making them for about $350 Ill rummage

install cost would be teh same as a clutch replacement as its teh same amount of work
