[QUOTE="Sielmo, post: 16058387, member: 170856"] I had a similiar setup with a couple sets of cams and had no issues of motor safety (768whp). The question of should you, well that's dependent on what your goal is. My experience is based on my 2010 where I drive it occasionally in heavy city or urban traffic without a whole lot of wide open road opportunities. I've had both SR and NSR cams and am now back to stock. My SR cams sounded awesome and gained me 96hp above 4500rpm territory but cost me vacuum. At 7.5hg, it was very easy to stall and since this amount of power required an aftermarket performance clutch, added chatter to an already finickier motor. (Really challenging in stop and go traffic, inching up a hill, lots of clutch smells) Swapped to NSR cams, and gained lots of streetabilty back (vacuum now 14hg) but lost half of that top end gain, and that choppy sound. With that said, top end gain above 4500rpm. Also to add, both sets of cams didn't tolerate normal DD (ie lugging around) in the 1500rpm range, so my car did a lot of hitching. My car also had the luxury of being a garage queen so I could do all the work on my own time (three times I did the cam swap which require substantial amount of tear down) In summary, SR (and some NSR) cams are nice choppy sounding and give good gains up high but will cost at least some DD driving ease. NSR cams are much better DD but choppy turns to lopey exhaust sounds at best and top end gains are less. Typical labor costs are about 2.5K and more if doing springs, add another 2k for the cams and springs. So, cams are a nice power adder, but what is your goal, how do you intend to drive it overall, and is it worth the cost? An afterthought note, although NSR cams don't require springs, most would recommend adding in better springs regardless. Sent from my SM-G960U using Tapatalk [/QUOTE]
