I have a fidanza 8.8 lbs aluminum flywheel in my accord....it revs much quicker than the stock wheel, I am very happy of the performance I gained. If you get it, you MUST get a better clutch, maybe an act stage 1 or 2. I went the cheap way and put an oem clutch kit in when I did the flywheel on my f23. I'm at about 21k miles since and my clutch is already burnt. I guess it didn't have enough clamping pressure. Hope this helps and congrats on the new engine.
