Hey guys, I was doing the rear main seal on my B18C and saw this flywheel in it. I have no idea if it's stock or aftermarket as I've never really touched B series.

Can anyone confirm what it is? I couldn't find any obvious markings on it to identify it.

 

Doesn't look factory. What's the weight? Any picture's of the other side?

 

I didn't take a picture of the other side as it looked almost like a factory flywheel.

I should've weighed it but I didn't, I don't recall it being heavy though.
