Ok, you are trying to replace the WG housing (the flapper assembly) or the whole turbine housing? Nissan WG housing should bolt up as long as you have the 5 bolt turbine housing. The new style T3 housing (4 bolt?) won't work with Nissan WG housing. (you need the 3 bolt Ford style I think)
T3/T04B hybrid.
I might be able to come up with one. I'll let you know
