I used a garret housing...I saw a dsm guy modify a housing and weld a vband to it to use on his hx52. I probably researched holsets for about 6 months now...because theyre not so main stream over here you have to dig for the info...but its there. like if you google hx55 2jz youll see guys over seas making 1000hp... not sure what housing theyre running but its proof for yourself that its doable. your best bet is custom.
