LT1 5.7L / 350ci Small-Block Twin Turbo Kit
Build your LT1-powered Camaro or Firebird project around a twin-turbo setup with stainless steel manifolds, a front-mount intercooler, aluminum charge piping, and supporting oiling, boost-control, and cooling components. This package is intended for a custom installation, not a guaranteed direct-fit or complete turn-key conversion.
