Hello ,
Main reason i have this nx264 cam right now installed in my car is because i got a cheap deal on it and it works well with the SD computer. Now i was comparing specs from the comp cam website between the xe264 and the nx264 .. they call the xe264 a mild street performer and a good stock replacement cam , they call the nx264 a high performance street with lopey idle (recommended nitrous or blower). My question is the only difference in the specs is more exhaust Duration At 0.006 Tappet Lift and different Valve Timing At 0.006 . How much does more exhaust duration hurt for a NA application? Since i have this cam in my car i want to understand it more!! Also comp cam mentions lopey idle but the idle isnt all that lopey imo.
Heres complete specs!
