You're going to have to contact them to get the specs or take the turbo off & measure it.
You never answered my question of does it make positive manifold pressure at WOT?
Secondly, you have to have the same A/R's.
If the compressor wheels are maybe a couple milimeters different, it may, may, work out somewhat OK providing the exhaust sides are identical. I wouldn't do it that way, ever, but it may work.
Why didn't you order another of the same turbo to begin with?

Need to know the compressor & turbine dims on both.
The big issue is turbine sizing, providing the compressors are even close to the same. That changes airflow & pressures across the side of the engine it is connected to. That requires different fueling & timing.
