the main reason those who do it here and don't care is because they change their turbos as often as they fill up with gas and 99% of the year it's parked in a garage in pieces.
I can't be bothered quoting anyone, but those who think it will or it won't instantly explode are just being retarded, Nissan wouldn't have planned the turbo to be a serviceable part so the recirc is there for the LONGEVITY of the turbo, and as GTSBoy said there are minor benefits to recovery spool time, likely negligible in 99% of circumstances. Given these are 20-30 years old now, stressing it this way *may* lead to it failing on you, so avoid the risk cause dose is f**king lame, or do it and enjoy the excuse to upgrade when/if it does.
