Question on differences between 75 an 90 B9s

[Godskitchen]

Hello all, 

I have searched and searched and can't seem to find an answer to the following :

The clutch on a B9 Berlingo 75bhp and 90bhp...

Are they the same/can the be interchanged?

I was always told the 75 & 90 was only separated by the ecu, all else being identical....

Thanks in advance all
