These vehicles do have eutectic pistons. The top ring land is very close to the top of the piston. This limits the amount of safe cylinder pressure you can run. Our standard 5-psi system is designed for use with these pistons. Adding nitrous oxide or increasing boost is not recommended on these vehicles. We recommend forged pistons (original equipment in 1992 to 1999 engines) for higher boost applications. Direct replacement aftermarket pistons are available.
