We are pleased to offer HP Performance twin turbo systems for the 1997-2008 Corvette C5, C6 and Z06.  HP turbo systems are the most complete systems on the market and provide the best turbocharger system value available today. These systems feature the same caliber of high quality and outstanding performance of all HP Performance turbo systems, all wrapped up in a package built specifically for the fifth and sixth generation Corvettes.   HP Performance provides a turbo system that offers very mild street manners and incredible amount of horsepower on demand.  For example:

A stock 2002 Z06 with the HP Stage I Twinturbo system made 670 rwhp and 640 rwtq @ 9.5 psi

A stock 2007 Z06 with the HP Stage II Twinturbo System made 725 rwhp @ 5.5 psi.

A modified 2002 Z06 with the HP Stage III Twinturbo System made 940 rwhp @ 15 psi.

A modified 1999 C5 with the HP Stage III Twinturbo System made 1010 rwhp and 10.16 @ 146 mph 1/4

Custom-made carbon fiber intercooler-intake tube

A stock 2002 Z06 made 670 rwhp and 640 rwtq @ 9.5 psi.

This is the view most people see of this 2002 Z06 with engine mods and a Stage III HP Performance turbo kit that made over 940 rwhp @ 15 psi!
 

Driver side turbo, air cleaner, exhaust and downpipes, and turbo-intercooler tubing
(heat shields removed for photo; cold side piping is black powder coated standard, ceramic coated cold side option shown above)

The systems are offered in three versions.  Stage I comes standard with 50mm turbos and will support 700-750 rwhp.  This system can be installed on a stock LS1, LS6 or LS7 engine, although it should be run at conservative boost levels due to the high compression and design strength of the these engines.  Stage II comes standard with 57mm turbos and will support 800-900 rwhp and will require engine modifications such as lower compression pistons, better rods, etc..  Stage III comes standard with 67mm turbos and will support 1000+ rwhp and will require more extensive engine modifications.
