FYI - Stock stats for a 1999 Civic Si
redline: 8000 rpm
5th gear ratio: 0.848
final ratio: 4.400
Tires: 195/55R-15
All this adds up to a theoretical top speed of about 149.5 mph. I have assume you have the stock gear set, but this would obviously increase if you have larger diameter tires and a higher redline from a chip or something. I just grabbed these stats off of some website, so correct me if they're wrong.
