i just came home from buying toda spec b cams i kinda just went off and bought them cause i was looking for cams and everyone told me it was a good deal. So now i do my research on them on the web site it said that i had to use there valvesprings. is this true? oh buy the way the valvesprings are some $$$ and on top of that because there egg shaped id have to buy there retainers to. i was told by the person i bought them from that it would be hard to get the car to idle right..is this because the cams are lopey or because of my ecu(first gen b16 black/green pr3 ecu)? what would be the best ecu program with such agressive cams? iam sure ill have more questions later thanx for da help.
