Iv just read that.

Gt1749VB are rare and expensive and so are VA units these days

But if u hybrid a turbo because I have a updates turbine wheel in it the results are EXCATLY the same is this ture or not?

Yeah pretty sure they give the same results - I dont think there's any difference in the physical size between the two units, just the size of the wheels. So if you hybrid a VA with the same components as a stage 2 hybrid150 turbo they should be the same. There's usually more 150 turbos for sale than 130's though!
