my uncle ordered what was suppose to be a jun flywheel for his b18 motor and when it arrived the guy that was suppose to install it said that they sent him a flywheel for a d-series motor. so for the past couple months the flywheel have been sitting in the garage. right now i'm converting my coupe from an auto to a manual and my uncle said that i could have the flywheel. i picked it up and its a plain white box, theres no name on it to tell what brand it is, no manual, or part number anywhere. it does feel pretty light compared to the stock flywheel on my hatch. feels like 10 pounds or something around there. now how do i tell the difference between a d series and b series flywheel

 

Honestly i dont know, but couldent u set it on top of your old one to compare size ext to make sure its the same, and count the teeth? but im sure someone on here knows just isent me but thats my quick solution

 

b-series have 8 bolts,d-series have 6 bolts

 

i'm converting from an auto to a manual since i killed the auto tranny so i have no old flywheel to compare to now i know the dif, thanks. gonna get to the workin on monday.
