We are proud to introduce our G4S-6868 turbocharger for the 1986-87 Buick Grand National/T-Type and 1989 Turbo Trans Am. Working with our friends at Xona Rotor, we have developed a package that will make any die hard Buick customer smile! This unit features a 67.7/94mm point milled, USA made compressor wheel rated at 95lb/min, and a 76/68mm 9 bladed turbine wheel. It also includes a 4" inlet ported shroud compressor cover, full ball bearing construction, twin compressor side seal rings, billet aluminum o-ring sealed backplate, water cooled bearing housing for unbeatable life and your choice of a .63 or .85 a/r ceramic coated turbine housing.
This turbocharger is aimed at the customer looking for a fast responding and reliable 950+ HP unit. It comes complete with -4AN oil feed line restrictor fitting and necessary water line kit for a trouble free installation. It is set up for external wastegate use only as we do not recommend an internal gate at this power level, however we have modified existing popular Buick actuators to fit. Contact us for details!
