Bonnett. What are you doing about the flange compatibility problem between the manifold and the turbo?

the manifold is a t25/t28 flange and the turbo is a t25/t28 flange, ill get pics of everything this weekend for everyone to see.
keep in mind everything is saab but the manifold and turbo, the turbo is just a higher output turbo, a step up from the oem saab td04l-14t, mine is the td04hl-15t or g

Something to think about - the bosch bpv from saabs leaks sometimes, but some people have been able to alleviate that by turning it around so that the dump side is plugged into the i/c piping and the intake side is dumping. I don't know how that works but everyone on saablink.net talks about it (I have a forge BOV on my saab, so I haven't tried it). Another thing to consider is that the diaphragm in the bosch BPV is plastic, unless it's from a viggen or 03+ which has a metal diaphragm inside (and also holds boost better when reversed) and in case you haven't discovered it yet, the bosch sounds like a woosh rather than a tweet of a usual BOV. when I had mine unhooked and dumping someone said my car sounded like a truck. It can be pretty loud still, but not as high pitched as a BOV.
