it was prtty well stock besides suspension, wheels, strut tower bar, intake, ypipe.... so it wasnt horsepower that was increased (well, maybe 5hp?), just the stability. I could out corner an integra GSR, pissed my buddy off.
so yeah, alot of us were surprised and we only knew it was 150 or 155 because a friend in a LS400 was pacing us down the "straightaway on the track" whos speedo went that high while mine was buried at "P"
