Ok, I just bought an eagle forged stroker crank for my b16 and I'm not sure on what size rods and pistons I need for an 85mm bore and 9:1 comp ratio. The dimensions of the crank are as follows:

part # 1633341772
stroke 3.335"
1.772" crank pin
.945" JOURNAL width.

.043" copper gasket

 

I think your best bet would be to call Eagle. They maybe be the only manufacturer that would have rods in the sizes you need.

Toda's stroker kit has a longer stroke than that, and Crower doesn't advertise theirs.
