Does anyone know where to get one, or do I pretty much have to make one...
The measurements are 76 i.d. / 91 o.d. on the turbine... Mine is the flat faced housing, not like CEcoatings...

 

Try a diesel truck parts shop. The HX50 came on mid-sized diesel engines. Got a pic? Is it a 22* or 45* angle?

EDIT: Where did you get the v-band clamp for it? They should have the flange too.

 

I don't have a v-band either....lol I will try a truck shop... I will get some pic's my dammmn Fuji cam died, but i have my good old nextel...lol

 

If the diesel shop can't help you then look at the Walker catalog. It lists all measurements and flange part numbers. If that doesn't work then call your closest Holset dealer. They set me up with a HX55W inlet gasket that no one else could get for me. I gave them the turbine part number and they shipped the proper gasket.

 

did you end up finding one?

 

Yeah went to a semi exhaust shop that had all of it and even could flare 4in exhaust??
