Need help ID'ing a turbo

[90T04]

I have had this turbo on my car for several years and it has never given me any problems, but I have always thought it spooled a little slow for its size. The person I bought it from years ago told me it was a T04B with a .69A/R.

The turbine housing is an on center design with the name "roto master" stamped on it. The hot side inducer measures at 2.84" and the exducer at 2.46". That would give it a 74 trim wheel.

What I want to do is find a tangential style T4 housing with a v-band outlet that will work with this CHRA and Wheel. Who would sell something like that?

Here are some pictures of it.

Thanks!

That is a 60-1 to4 platform.

Its either a O or P trim turbine.

Wow, I knew some one would have all the answers. You guys are awesome.

so what options do you have as far as A/R's and inlet/outlets. I would need a T4 undivided tangential with a 3" vband out. Im looking for great low end spool and since this isnt a ball bearing, I was thinking around a .70 A/R. Have anything like that?
