Ive bought the above injectors and also the cups from zen performance but the collar of the injector doesnt sit well in the rail. If I use the standard rubber collar seal from the standard injector on the blitz injector the injector site ok and looks like it will seal but I doubt it will with 3.5bar of pressure behind it. Are there other collar adaptors for these injectors?

Thanks

The Blitz injectors you have are not phase 2 injectors, but injectors from a Mazda RX-7. The problem you are having is the adaptors are for a proper Phase 2 injector like those on OE subaru applications, and the Nismo style 550(yellow) and 740(red) injectors. What o-rings do you have at the nozzle end of the injector?

You should be able to buy the correct adaptors for these injectors, they are the same basic type as the Sard injectors. We have some other adaptors specific to the Denso injector, they may work, but they are normally fitted with a collar at the top of the injector too.
