Got a couple stock flywheels lying around and need to know which if either came off the D16z6. I tried searching here and honda swap, but no luck. Will be putting in a clutch for someone and wanted to speed things up by getting one of these resurfaced in advanced if it's the correct part.
Anyhow,
One has 8 bolt holes to the crank, "P30" stamped in 4 places around the back edge and the following about halfway toward the middle: AG, M4, 3B, 25

The other has 6 holes and stamped around the middle: AC, K1, 85, 21

Both have pilot bearings.
Unless I'm forgetting something they are either for a 94' Civic Ex (or Si), 94' GSR, or 90' CRX. Just don't know which. BTW: next time i'll label them.
Thanks

 

8 holes and P30 means B series.
6 holes means D series.

 

Anyone know how I can tell which D?

 

6 holes.

 

I think all D series flywheels are about the same...

 

nope.

88/89/90-2000

then you get into the different weights.
