Does anybody know the compressor and turbine A/R's of this turbo? Its an IHI Rhb5, turbo spec VF48710, serial number RHB5 28410. It has a 3 bolt exhaust inlet. It's off of a Subaru

That looks like the one in the Apex-i kit, I searched and searched, and I couldn't find anything eather. I even called Apex and they didn't even know. But it spools HELLA fast! specially on a B16...but I run out on the top...

I searched for hours too. Why the ---- is there no imformation on this turbo? I think IHI stopped making the RHB series and replaced them with the RHF and RHE series thats why theres not too much information available. But I'd really like to know what the A/R of the turbine housing is
