sorry i cant help but just to add, ide really really recomend against putting any type of sealant or exhaust paste above the turbo, uve only got to get a little in to the turbo and it'l shit itself, copper sealents not so bad i guess, but anything thicker is a big no no imo. and my friend did just this, put exhaust paste on a crack in the mani, sucked that shit in and killed the turbo
