I have 2 friends that have RSX's. A type S and a Basic model. Both 5-speeds. The type S at the track put up a best time of 15.3 all stock. The basic model put up a 15.9 and that was with intake. I run a 15.9 w/o sqeezing, so we are not far off. A lot depends on the driver too. Oh yeah, with I-VTEC, the vtec is always working, it's not like the original vtec where it would kick in at a certain RPM.
