The turbo is for the 4G63. The 420A is built strong, but not strong enough to beat the hell out of with 12 psi of boost on a motor with 150,000 miles on it. The pistons are Cast and the Rods are powdered aluminum if I recall correctly. Rebuilt with forged internals they have shown to be nearly bullet proof.
