1998 impress Irish turbo. It is a ver4. I made sure when I got this greddy bov that it didn't have the plate like v5 and above. But it has different pipes I think. So can this fit my car
are the subaru versions so restrictive that it cant be modified. what is each pipe for, do i need to use all the pipes and nipples on this valve for my car. was reading somewhere that they are not all used, but cant find that reference again.
