Your very confusing. What are you looking for a .85 or a .82? A Precision .63 is in between the Precision .85 and Garrett .63 as far as converter needed to spool. A .82 Garrett cut for a 44/49 is very rare. I have one but it would need to be machined to accept the turbine on the 49 because is machined for a stock turbine. Precision would do it for a fee.
