I saw a timeslip for a s2000 w/ Intake and different tires run a 13.9.. and most average around a 14.5 and I know a stock N/A doesn't run near that.. .more like 15.5. Now at stage 3 on an N/A you'll be hopefully pushing a 14.7 or a little lower depending on the driver. I give it to the s2000 no matter how much of a fan or once-owner of the great and dream car that is known as the Z(except I owned a TT and will never go to an n/a Z unless it's the new Z that's coming out)
