Well I ran a 14.7 with a nasty bad clutch and stock exhaust manifold with the oem cat. Did I tell you Im a horrible driver ?

After I get the header and testpipe installed and the new clutch and some practice and few other secret tweaks..I expect low 14s or high 13s...13.5 is my goal after internal works or 250-260hp is my hp goal. Im into streetable performance and not just 1/4 mile.

Sis are not that quick as people think but after well chosen mods and the driver ive seen high 14s with just header and exhaust.

Ballzy2000Si can give you a good run for your money. I have raced couple of Sis around town with some mods and I can tell you hes the fastest n/a Si Ive raced before.

IMO but again... Im a slow bastard ! !
