Number of fan blades on S4 or S5 TII
Is it true that the number of fan blades are different on a S4 and a S5 turbo II engine ?
I found a picture of a S4 and it has 8 blades but does a S5 really have 10 blades ?

I want to order an engine from Japan and they want to know if I need 8 or 10 fan blades...

On the N/A anyway the depth is also different. They were not interchangable (I tried).
