I have a EG5 - and i have a TODA flywheel



Cost a pretty penny but worth it IF replacing clutch at the same time....low speed driving = no different to stock BUT once you start revving u will notice the response difference.

You can get TODA , Exedy locally/imported - or even a JUN etc.

Otherwise you can import from the US - search on www.d-series.org for more info.

i have an exedy light weight goin into my zcasauraus soon

i know wont help much but i have a Toda lightweight fly in my DC2

i noticed straight away a improvment over the stock revs quicker through the rev range
it doesnt equate to more kw but car is more responsive and just feels quicker hard to explain
but alas i have now got used to it but i still would recommend this upgrade to anyone
on a side note it now takes more revs to keep the car cruising say on highway drives but not a big issue

My toda fly cost $730 about 8 months ago now i also had the clutch changed at the same time becasue your taking the clutch out to get to the fly and its not cheap for a mechanic to go there....

didnt know u got one eh Lerroy ? Nice
A lightweight flywheel does not increase HP at all - essentially it feels like the car has much less weight to haul around and the response in both acceleration and deceleration is increased.
Yup - saves you to install the flywheel at the same time as a new clutch - $300 labour to do it in so save up and get it done in one hit .

it is true i do have one :P

As ben said i dynoed my car after there was no improvment in KW numbers
although the curve had more of an angle to it steeper climb :P
when i first drove the car from the garage i was very happy felt like a new car very responsive

when you let your foot off now you will notice a bump especiely in 1st gear because the flywheel does not have as much enertia being lighter so it stop/slows alot quicker this is something you have to get used to
its not a big deal :P

good luck with purchase you should be happy if you stick with the brands mentioned

there is another option where you machine the stock flywheel taking off excess metal this lightens the stock wheel but can casue problems in the long run the wheels becomes weaker and prone to warp and or cracks, the right person has to do it for you

bleh im doin mine asap now, thanks leeroy

Trav lerroy !!
hahaha
and no worrys mate just pm you back

[Zdster]

Just curious, do you get better fuel economy with a lightened flywheel as it takes less energy to turn the flywheel? Anyone know/have any idea?

Interesting thought there - we need some professional advice in terms of energy conversion and storage methinks.

The problem is you will find yourself revving the car much more for obvious reasons

Also , IMO i would not machine a stock flywheel at all - not just for safety reasons but for the results in comparision to a aftermarket item. ( IE you cannot machine a stock flywheel down to the level of a aftermarket one reliably)

I think it depends on whether you are doing highway driving (fixed speed) or city driving (variable speed).

Highway driving - More inertia with stock flywheel = easier to keep speed
City driving - Less inertia with lightened flywheel = less work required to accelerate.
