ive seen ctr cams go for about $550/set, while the cheapest ive seen sk2 is aorund 680-700.

from what ive heard, the ctr intake cam is more agressive than the itr, but the ctr and itr exhaust cams are the same

ive also heard its not necessary to upgrade the valvetrain with ctr or sk2 stage 1. can anyone verify this? i dont think i can trust the 10yr old retainers and springs in my motor.... btw, how fast can the stock drivetrain rev? im getting my ecu chipped, and the limiter wont kick in till 9k. i dont even take my motor past 7 now, i dont kno what use the extra 1k is gonna do anyway, unless i get some mad cams
