i believe that my throw-out bearing is going out and my clutch slips a little, SO while i am in there i should redo the oil separater plate plus the rear main seal on top of the other clutch related parts, what lightweight flywheel does everyone recommend?
i like the exedy one but i dont know how much it weights or really what one i should get for my car the
ff01 (http://www.exedyusa.com/race/FF01)
ff02 (http://www.exedyusa.com/race/FF02)
and not sure if i should get an oem clutch kit or a stage one clutch kit ?

is there anything i can do with the shifter so that it doesn't have as much side to side play while in gear, like a bushing kit or something?

ff02 (im guessing its 14.9lb or more since its steel), and 15801,

I can get clutch kits and flywheels, but no Kartboy stuff yet.

just to be clear i have the nice 2.2L SOHC
i was pretty sure that i needed the 15010 bc i dont have a turbo,
Reason can get the clutch kit and fly wheel from you right?

Fidanza makes an aluminum 9lb one with inserts (not really recommended due to inserts)

TODA also makes one, either a 9 or 12-14lb one, I forget for JDM tyteness.

Can't go wrong with the ACT streetlite IMO. It was probably the best mod I did to my car when it was still NA.

Check out the clutch & flywheel combo's on offer from Gruppe-S on nasioc.com too.

I would tend to stay with the same manufacturer for both the flywheel and the clutch - logic says they will do their testing using their items... maybe I'm just paranoid.

I know some people will run the 9lb flywheel and not report any problems, but I would stick with a 13lb - it's still 7lbs lighter than stock, and a STOCK clutch is going to be fine. Clutches are HP rated, so unless you're considering going above 200hp then a stock clutch is fine.

15010 is oem replacement
15801 is stage 1
either fit 2.2, 2.5 engines

I've had my Fidanza flywheel for over 74k miles now and I love it.

Try to hold off and get a light flywheel. Both my cars have Fidanza's and they work great. I don't like driving my friends car with its heavy flywheel at all.

well its either lightweight flywheel or new phone to replace the one that wont charge right and only holds a charge for one 5 min call.
PLUS
i've already ordered a 23lbs one from Advance

Could have had your stock flywheel machined...

23lb stock flywheel + resurface = lighter flywheel :grin: i think it droped the weight to 21.5lbs

Ahh you don't need a new phone, get the flywheel and a new battery for your phone. :smile:

I couldve just given you my old one and you couldve resurfaced that...

dont believe in resurfacing its almost the same cost as a new flywheel

you know those standard flywheel that cost $50-$60 are resurfaced flywheels?

So you don't believe in brake rotor resurfacing either?

warped rotors is the only reason my family has rotors turned, and they never seem to come out correctly

Huffer

Warped rotors are a bit of a myth... typically there's uneven wear due to the brake pads or inconsistent braking. To warp a rotor requires a massive amount of heat, over a very short period of time.

But hey, whatever floats your boat.

How is the driving experience different with a lighter flywheel on these cars?

Depends on how light you go - they'll rev faster and drop revs faster. Less drivetrain lag so you should be able to shift faster, and less power lost in trying to keep a chunk of metal spinning.

MPG should go up as well. Some have issues with alternators not charging if you go too light on the flywheel. The 13lb'ers are more recommended because of that.

I believe jey has a 9lb flywheel.

Using a street type disc, once you develop the muscle memory (maybe a 1 day process for me, and I'm a slow learner), it'll seem weird to go back to a heavy one. That is why I installed one in both cars.

BTW, mine are 8 (DSM)and 9 (Legacy) pounders.

Hope this helps.

:lol: Though it's good to also point out that just like brake rotors when you take away material you compromise the structural integrity of flywheel. There are some that refuse to resurface, especially aftermarket flywheels - when flywheels experience structural failure it is a very nasty thing. Think about a catastrophic failure at 7000 rpm. In the professional racing world people lose legs from flywheel failures.

Yeah I dunno about that - the alternator is still being driven at the same speed... I think there might be some confusion about the effects of an underdrive pulley (which can cause alternator charging issues).

And yes the Fidanza flywheel I have is 9.5 lbs.

well the car has already had the motor out had the maintenance done and put back together, my old man forgot to tighten down the positive terminal on the alternator and it fried itself, and when i went to get a new one the terminal was too big so i had to make another trip to Advance and trade the terminals on a positive note my old alternator was the source of a squeak that was driving me crazy.

also installed a custom grounding kit, LOVE it idle is smooth as silk and starts a little faster and doesn't hover around 1500 rpm for a while rigth after starting
