Just wondering if anyone has seen the inside of a BA turbo manifold, and the difference they are from the NA models. I know they don’t have the dual runner butterflies, but is that the only difference??

Thanks.

im not sure but i would say it just a big open plenum. but still looks like a bbm

hummm, I've got a pic of the bottom half and it looks the same as the EF/EL ones, just without the butterflies, I would really love to get a picture of the top half, or if someone has pulled on appart just as good..
