Subject title says it all. I've done lots of searches on here. I read conflicting views and experiences. Some say do it with only heavily built engines 700 HP+. Otherssay it's ok for engines in 500 HP +. I've also done a few searches on search engines and mostly get domestic forums bashing brands etc...1: Are upgraded cams beneficial in Z's with bolt ons ( pretty much everything you can do ) 2: Is there any benefit to do with mid power BB turbos? Or only beneficial with the big boys ( 700's + ). 3. Is the idle smooth and manageable for street driving? Is the idle higher? 4. My prev. post on cams many says it's not "lumpy" like a domestic that has cams. All the videos on you tube I have seen sound very "lumpy" like domestics. 5: Any other brands then JWT? Thanks in advance.
