Visual difference of T28 from T25; dual and single blade question

[2gGSX]

I've recently located a good conditioned "T28" locally, and just wanted to make sure it was actually a 28 and not some sort of scam. Obviously it's sort of hard to tell the difference, so I was searching and I found this thread

The pictures at the bottom prove that T28's are all dual blades, but can anyone confirm that T25's are single? Or are they dual too? (my excuse for not looking myself is its cold, its 2 am, and I'm a little tired ) If anyone knew this off the top of their heads that'd be great.

the difference between the t-25 and the t-28 is this, the turbine that you can visually see is bigger than a t-25. the housing is exactly the same and it looks identical except that turbine. if you look at a t-25 there is more space along the sides than on a t-28. the t-28 will have almost no space at all. a t-28 is a t-25 turbo with the turbine replaced wiht a mazda one.

depends on what "version"
