No Industrial turbo here , Tried that route also no luck ,so decided to send my own unit in for rebuild , they may sell some II stuff but mostly borg warner ,garrett etc, Not sure wheel size?type for II hp (57,58/cast wheel) I think they are just running a 58mm ,Apex has a set they stock 71mm/55mm billet wheels , but in talks went with a bigger 59 ,only cost to me was the upgraded titanium wheel !!
I did have the wheel size/type changed in my set up to 59mm with borg warners new Titanium aloide wheel !!!
I think they are in your neck of the woods , Give him a call JJ , ive been really happy so far ,but will see how it goes when they get installed

they did there own machineing but did send out my turbo housings to get polished
