It all depends. With frankenstein motors like LS/CR-vtec, you don't have the kind of quality control as you would with a factory honda motor. The reliability of the motor is only as good as the guy who built it, and the parts he used. It is possible to build a perfectly reliable CR-vtec motor, but it takes an experienced engine builder... There's plenty of room for error.
