I don’t really know. There are a few that have done low 13’s with stock set-ups. Which is where the reviewers dialed it in at. And there was a guy in the USA who did 12.81 with HFC’s, CBE, and CAI bolt-ons (just like me). I’m not really into 1/4 mile though. The 370 is more of an Autocross car.
(For you nay-sayers, here’s a link to his time sllip: 12.8009 @ 110.33 - Page 2 - Nissan 370Z Forum
You may have to cut & paste that link to make it work. This forum may not like that url)
EDIT: The guy is actually in Ontario who ran 12’s. Go figure.
