I have found the following information
wastegate (tial 44mm v band)

ebc (blitz dsbc)
http://www.nissansilvia.com/forums/inde ... _id=145122
from what i can gather, i need to plumb the bottom (side) port of the wastegate to the intake manifold

The top port goes to the "out" of the dsbc and the in port to ebc comes from the manifold?
or have i got that wrong?
cheers
