How to tell T-28 from T-25

[NickMOSU]

Ok, so I was researching and I'm wondering what the visual differences are between the various T-28's and T-25. I found on Vfaq that the T-28 obviously uses wheels. Also, it has the 7cm housing correct? Any info would be great. Thanks for help.

The way I check is, I measure the outside wheel on the compressor housing, the T25 should be around 1.5 inch while the T28 measures 1.9. Also the lip on the compressor housing (where the intake connects to) is alittle thicker on the T25. Hope that helps.

The first pics shows a T25 to the left, and the one to the right, a T28
