My wife has a 05 Infiniti G35 6sp manual, no mods. I've got a 2000 Boxster S with an EVO intake, modified muffler, and modified cats. I'm happy to report that the 986 S pulls away at any speed.
Before I had the 2000, I had a 1999. As you know, the 2.5 doesn't really come to life until it hits 3500RPM...the G35 would be gone by then
