As stated, I am looking for confirmation if a lighter than stock flywheel will cause a misfire code on an 8th Gen Si

I seems strange to me but it is clearly stated as such on K-SeriesParts website and they restated the same to me again on the phone today. The only fix is stated as a FlashPro to turn this off permanently.

From my own research, I can find evidence of this happening on 9th gen and newer but nothing I have found states if the 8th gen Si has the same issue.

The reason for asking in the first place is that I am at ~145Kmiles and the clutch has definitely started slipping and needs to be replaced. It is still drivable right now but for how long. I would like to buy a complete kit with a flywheel and everything else and be done. I expect that the stock flywheel wont be in the greatest shape and buying another oem on is $$$. Unfortunately, locally I am not having luck finding a shop willing/able to resurface the original

I was in the same scenario with machining and the oem flywheel cost. A real machine shop can do a stepped flywheel but i wanted to do everything at one time so i bought a fidanza flywheel and an oem exedy. No misfires. Definitely lost low end at stop lights which makes it a little difficult to take off. I have around 20k on this setup. Flywheel is around $180-200. I have a 2006 no idea why you would get misfires.

Thanks, that's what I needed to hear

I know the 9th gen will misfire with a light flywheel. But haven't heard anything about the 8th gen
