What you have to do to build a competitive race car for IMSA GS class or PWC GTS class out of a Z makes it inherently unreliable unfortunately. They are basically a cost-no-factor N/A build while maintaining the 3.7L original displacement (a rule requirement in both series). Conversely, the Mustang's and Camaro's are mostly just running an intake, headers and exhaust, typically with a restricter of varying size, and the motor is a lot closer to stock making it a lot more reliable.
