9.5 pounds is very light. I think you'll have some driveabilty problems.

I have That flywheel for the KA and I don't Have any problems with It. Actually I love it. No driveablity problems. absolutely great.

[Thoughtful_One]

Yes, but the flywheel for the KA weighs more than the flywheel for the SR...

I have one with a spec clutch it makes the car rev way faster you have to shift faster then stock i like it.

why do you say that?

[nwmrkt]

why do you say that?

he means, the lighter the flywheel that faster the rpms move...so you would have to shift faster or the rpms will drop really low fast.

[tEknoS13]

yup. cant wait till i slap it on!!! so excited so far every1 has something good to say about it. walbro 255lph coming in tomorrow

Loved it, daily drove with it in combination with a ACT clutch for over 2 years, including a 4 month stretch with a 3 hour daily commute in stop and go traffic. Still have it and im going to use it again when I stick the sr back in. The only way you will have drivability problems will be if you use some totally unnecessary 6 puck unsprung clutch with a ridiculous pressure-plate. Otherwise, its much better than stock in every way (including drivability in my opinion).

[tEknoS13]

awsome. thanx every1 i can tell itz going to be bad ***....

I put in a Fidanza with an Exedy stage 1 and it's excellent, big difference in revs.

i understand how lighter flywhels work...... but why is having to shift faster a drivability issue? you'd get used to it pretty quick.

i will be running a toda fly pretty soon. will let you all know how it turns out.

I have a toda flywheel doesn't rev up that fast had a fidanza and loved it. Need a new clutch soon though looking for another fidanza flywheel. There won't be any drivability problems with the fidanza flywheel, don't listen to that crap. I went from stock clutch & flywheel to fidanza and exedy stage 3, 3 puk sprung, rediculous engagement, but no drivability issues. No worries u should be just fine my man.

[tEknoS13]

kool. i just put it on my sr and my clutch.... damn that SPEC clutch looks good. dat flywheel is so light... i cant even pick up the stock sr flywheel with one hand!!!

+1 for Fidanza.

There is a video some where of a guy who recorded his tach as he revved it up with a stock flywheel, then revved it after he put in his Fidanza. Then he put the videos side by side so you can see how much faster it revs and falls.

EDIT: Found it. Video is by Arqi. I dont think he posts here anymore though. http://users.adelphia.net/~arq...a.wmv

Once the engine and transmission are coupled together, I don't see any problems with driving the car, but I would think engagement would be a little tough in stop and go situations.

no no, i didnt really mean "drivability issue" perse, I just wrote it...it defenitly wouldnt bother me.

Fidanza & Exedy stage 2 here. Love it.

Heel toe downshifts are great with this setup. I can get alot more rpms with a quick blip of the throttle than with the stock flywheel.

I heard many times from many diffrant people that a heavy flywheel is better for drag racing. INERTIA! If some1 who relly knew their stuff about inertia and whats best for our SR20DET(for drag,drift,roadracing and street) could give us all a lession you would be the MAN or WOMAN!!! I bought a ACT prolight flywheel(9.5lbs) but chose not to use it because 1. I like dragracing 2. I also heard any moter spinning faster than 7k RPM Must be factory BALLENCED AND a lightened flywheel might throw off the ballence! Please school all of us because we all learn something new everyday!!! O yah I love drifting!!! to all you great nicogoers!!!

[cheapscheisst]

i don't have any issues w/ my fidanza and nismo 3-puck... great flywheel

[tEknoS13]

well... if ur into drifting i guess ur right. dont get me wrong, i love drifting but i dont intend in doing so. im just interested in smoking all them loud mouth V8's. i know the stock sr wont cut it, but it will in a few months!!! dont know man i heard wonders about this flywheel. i guess i got to wait till i drive my car.

[CMG]

There are some engines that you should not have both a lightened flywheel and a light crank pulley. Sometimes the crank pulley is a kind of harmonic balancer, so you have to be careful when changing that. For the SR there are no issues with having a lightened flywheel, and I believe there are no issues also with lightened pulleys.

I am having an SR swapped in, and I just bought an ACT Prolite flywheel. This will be used with an Exedy Stage 2 clutch.
