Herbst

So I got a JCB GT2560S turbo a while back and when I bought it I didn't realize how weird the exhaust housing was. I just saw it was close to a t25 and assumed it was a t25. Someone told me a SR20 housing would work, but it was way to small. I sent the specs to ATP Turbo but unfortunately they couldn't identify it. I'm about to scrap this whole turbo if I cant find a housing that will fit soon. Any ideas on a housing that would work? The turbine exducer is 44.2mm and the inducer is 53.85mm give or take a little. It seems like its a T28 turbine, but the exducer is a little to small. I was thinking of trying a t28 housing, but it looks like there would be a 3mm difference in the exducers.
