Lemme put it this way to end all arguments of all time about CA vs SR vs KA vs RB vs VQ vs etc. The engine who’s owner’s wallet is the fattest is better. None of you can compare any of these engines. As its comparing apples and oranges… the reason for this is because there are many different mods/parts/routes one can use/take. All these engines have made more than 700whp so it doesn’t really matter what anyone argues till you get it to that hp then complain that you should have chosen the other engine. I don’t care if you think a RB is better than a KA… “It has more potential in every way”. A properly installed RB26 will cost you close to 10000. that will give you the stock hp of around 300. if you bought a KA and put that much money into it it would create more horse than that RB. It all comes down to money… with money you can make anything possible… Please stop arguing this and if you decide to add to the ocean of useless opinions think about how irrelevant it will be as there is countless threads on countless forums on this same topic, and guess what none have come to a conclusion… all there is , is opinions. Instead of fighting about which is better… talk about what is better in one specific area… CA- High RPM… KA- large displacement(low end torque) SR- Well rounded budget engine… all of them are beautiful engines by nissan. Depending on different people’s preferences and budget different motors are right for different people. Yet all motors are great motors when done up properly.

Wrong CA’s, SR’s are square engines = mid to high rpm power. KA’s are under square.Cams durations, lift and overlap do come into play with you powerband though. Anyone on these board actually know engines??? So much wrong info spread by the blind, and followed by the blind.
