gt37 oil flange
 

im having some trouble finding a oil return flange for my gt37, most flanges only go upto gt35. anyone know who makes a flange i need

thanks

Is the hole square shaped? If it's circular you can drill it out bigger and tap it for a fitting.

If it's square with 2 bolt holes on either side, I guess you gotta find a flange.

its round with two bolt holes, 50mm width hole to hole. i found one on ebay in cali but dont want to pay shipping and duties for that small piece.

There are a few turbo specialist shops around (some of them are diesel shops), try searching and calling around...
