alright im having a problem choosing which cams i want to use for my b16 thats in my rex. i was thinking about going with buddy club spec 4 cames with p1 valves, springs and retainers. i just want to know if any one has tryed out the spec4's and if ther worth my time and money or not. also what kind of internal mods must be done to put them in? my big question is wich cams are better buddy club spe3+,spec4,spec5, spoon,toda,jun or a pair of ctr or irt cams. my goal is to build a all motor setup with about 275whp
