bc stage 2 cams

[nicks240sxs13]

hey guy, I got a 19' 240sx with a sr20 red top and i was thinking about getting some cams in the future. I was looking at the BC stage 2 cams and had a question that i couldnt find the awnsers to by looking up reviews and stuff.
they are 264 cams with 12.06mm of lift and it says they i dont need to upgrade my valvetrain and i was wondering if anyone knew if that is ture or not? and if it is are the direct drop in or not?

BC says to use springs and retainers, then yes they are needed. Becomes expensive doesn't it? And to think it will still require cam gears as they are junk cams, and will still make less power than Jim Wolf S3's or HKS 264 Step2

Save the frustration, buy a set of Jim Wolf S3's (no need to upgrade springs or retainers) and make more power. Much better cam, install as OEM and kick ass.

so the jw s3 260 cams are direct drop in?

Drop in and forget. ALL JWT "S" series are safe for stock valvetrain.
