both cosmo 13b-re primaries and fd secondaries are side feed, correct? If so, is it possible to use 850cc secondaries off a 13b-rew as primaries on the cosmo? Physical difference? Impedence doesn't matter

thanks!

 

Yes it's possible, that's what I'm doing with my RE 850cc primaries.

 

hm, here's a pic of cosmo primary injector on the right, FD secondary injector on the left. physically, the rings seal up the FD injector in the primary RE rail, but it's a bit short as you can see

Question is: is that diffuser removable from the RE injector on the right? If so, can it be transplanted onto the FD injector?
