Cam help please!!!

groupbuycenter has a deal on crower turbo cams retainers and dual springs for 600 bucks. Is it worth it to buy these or should I shell out the money and buy a pair of jg turbo cams, or crane cams. Anyone know anything about turbo cams for the b18b, or have any dyno results that could help my decision. I mean if its a difference of 5 hp then I'll go with crower but if Jg is that much better or crane or toda or whoever I'd spend the extra money.

Thanks for the help in advance.

All I can tell you is that I have heard nothing but good things about crower. I myself have a set of crower 62404 cams and they make a lot of difference, but you must have a set of adj cam gears and some tunning time to get the potential of the cam. Sorry if i was no help.
