recirc bov? searched to no avail...

[fitch9014]

I've got a 1991 240sx hatch with a '90 ca18det. On this I've got an s13 redtop t25 turbo and a greddy rs bov that is atmospheric right now, I also am going to run a saab 9000 fmic with smallish piping (2.25"). I'm trying recirc the bov and I found the adaptor. The only problem is that I don't know what diameter to run...There are four different sizes, I'm thinking 19mm or 29mm...but there's a 32mm and a 35mm, too. I just need to know what would be ideal or if diameter even matters at all. Thanks, sorry if this isn't the right forum.

here's to beer

the recirc depends on the diameter of your bov. take a ruler to the opening of your bov and get some hoses accordingly.
