Hi, Im looking into a lightened flywheel for my car (2000 integra GSR). The choice is between the 7.5lb fidanza flywheel and an exedy flywheel (dunno the weight, i think its around 8lbs). Does anyone have any opinions or experiences with the exedy flywheel? Its a comparison between the two, fidanza and exedy flywheels...which is better?

have not used the exedy but have the fidanza. Seems well engineered and works well so far with my exedy clutch.

There really shouldn't be any difference between the two, I believe they're both aluminum (shoddy memory, Exedy might be chromoly). Either way, I LOVED my Fidanza on my LS - it was fun as hell. Shifts need to be a tad bit quicker to be smooth, but I could feel the car accelerate much quicker. If you search, you'll find this pretty much this as the HT concensus - "most worthwhile mod for the money, IMO".

I whole-heartedly agree.

Fidanza's are cheap too, ~$200. I know Exedy's are right around that price too, but I can't tell you exactly how much. OH and if you still have your stock clutch, swap it with an Exedy or another setup while you're there - you won't want to pull the transmission more than once unless you need to.

I never had a problem from either the Exedy or the Fidanza. The Fidanza is lighter and cheaper so why not the Fidanza.

ya, well, the reason i ask is because i can get both for the same price. I wanted to kno if anyone has heard about the exedy flywheel...bc i havent really heard much about the exedy flywheels, and i kno that the fidanzas are really good.


Also, ppl say that you lose torque from getting a lightened flywheel...is the loss of torque that noticeable?

You don't lose torque, it's a myth and don't let anyone else tell you otherwise.

How can a piece of reciprocating weight that's outside the motor actually effect the motor's output? The thing you notice is that your starts need have a little more throttle applied or you need to learn to release your clutch gentler. This is because a flywheel with less mass stores less rotating energy than a heavier flywheel spinning at the same speed so when the clutch grabs it, the overall energy transfer to the transmission is lower. Therefore, just give it a little more energy (spin it a little more with the throttle) and you'll be fine.

Once you drive on it for a day or three, you get used to the clutch again and you won't even notice the difference on launches.

vgsr

cool...just wanna make sure. I didnt think it would loose torque either bc energy output is still the same.

Anyways, does anyone have the Exedy flywheel? anyone have opinions?...i just purchased the exedy stage 1 clutch, now i need a flywheel ...rite now, im leaning towards the fidanza, bc i havent heard much about the exedy flywheel

Yes i have the stage1 exedy with exedy chromoly flywheel.

I have had no problems. The revs drop somewhat faster, therefore, you have to shift faster. It was good with my ls tranny, now with a gsr tranny its effect is better.

i also just purchased the exedy stage 1 and chromoly (exedy) flywheel, about 1000 miles ago, so break in is over.

i love the combo, both terrific replacments for stock components with the clutch feeling just about stock (great for the daily commute) and the revs are much more free flowing. as mentioned before, you have to shift quicker to get the same smoothness as stock, but thats the fun part i haven't done any burnouts/rev drops yet, prolly another 1000 before i feel confident in doing that, but i have done 6k+ rpm pulls in 2nd, 3rd, and 4th and the stage one grips great and i don't have as hard of a time staying in vtec as i thought i would.

i love em. btw 95 gsr.

An important point that these guys mentioned - the Exedy unit is constructed with chromoly and the Fidanza is aluminum. Chromoly's stronger than aluminum, but that's not to say that aluminum is weak and the Fidanza is going to shatter on you - it's still a rock hard unit.

Just note: I've never heard of a single Fidanza flywheel (nor Exedy, for that matter) to warp or fail with a proper install. So the material they're constructed out of might be something to think about, but it really shouldn't be a factor or selling point in your purchase. IMO. You're getting a great deal and a strong part with either.

Action Clutch just released their 8lb Aluminum and 12lb Chromoly flywheels. You might want to check out theyre stuff. Not trying to sell you, but just wanted to let you know what else is out there.

vgsr

cool, thanks for the info. The two choices i have are between the fidanza and exedy flywheels...both are aluminum, the exedy that i am looking at is not chromoly. Since both are made out of the same material, I think im gonna go with the fidanza 7.5lb, i think it just looks more solid in construction, and i have heard alot of good things about the exedy st.1/fidanza combo. Thanks for teh help

psychotic_z

Sure thing! And if it helps, I'm running Exedy Stg. 1/Fidanza in my LS and it's deh hotness.
