Katech Performance, builders of the C6R Corvettes, took on the task of bringing the C6 Z06 up to the next level. That level includes a 600 HP motor, along with a thorough reworking of almost every component that makes up GM's blue-collar supercar.

To begin with, the "Street Attack" LS7 gets dismantled and then stuffed with forged 11:1 pistons and titanium con-rods. While the engine was cracked open, Katech replaced the valve springs, camshaft and retainers, along with porting the cylinder heads. All those modifications boost output an additional 100 HP, a figure that will supposedly be reached by the rumored Blue Devil 'Vette –- except this Z06 doesn't have to rely on forced induction.

All those additional ponies couldn't be found by just working over the block, so Katech replaced the stock exhaust manifold with a set of Kooks ceramic-coated headers and installed a CORSA stainless steel exhaust.

Power is sent to a higher performance clutch and an upgraded RPM Stage IV T56 tranny with cryo-treated greasy bits. As for stopping, the company opted to stick with the stock brakes and pads, only changing the brake fluid and installing Stoptech stainless steel braided brake lines.

Inside, a hand-stitched Caravaggio flat bottom unit replaces the stock steering wheel, while the shifter boot and parking brake sheath get replaced with the finest dead cow. A custom shift knob, along with a numbered plaque also increases the exclusivity ante.

Katech insists that the Street Attack is still capable of making the daily commute, albeit a bit louder and considerably faster than its stock counterpart.

The company's full press release is posted below.


Katech Performance Allies with Endurance Racing Legend Dick Barbour to
Produce Corvette C6 Z06 Package

CLINTON TOWNSHIP, Mich. – Katech Performance has made the Corvette C6 Z06 even better with more power and enhanced induction, cooling and exhaust. The C6 Z06 vehicle package (KAT-A4691) promises 600+ horsepower and fine finishing touches for enthusiasts who desire a truly unique Corvette.

To develop the package, Katech Performance consulted with endurance racing legend Dick Barbour of Dick Barbour Racing. Barbour's accomplishments include multiple 24 Hours of Le Mans and 12 Hours of Sebring class victories as well as three Sports Car Club of America (SCCA) championships.

"Katech's own rich motorsports history includes more than 50 driver's and manufacturer's championships," said Caleb Newman, vice president, director aftermarket operations, Katech Performance. "The C6 Z06 package draws from our collective expertise. We've crafted a vehicle worthy of the most astute Corvette aficionados."

The C6 Z06 package features a Katech Performance "Street Attack" LS7 engine with Katech forged 11:1 pistons, solid bushed titanium connecting rods, upgraded camshaft, high-lift beehive valvesprings, ultra-light titanium retainers and ported cylinder heads. Other modifications include a Katech adjustable billet aluminum belt tensioner, coil relocation brackets and paint-matched valve covers.

"Our Street Attack LS7 produces 600 horsepower for the C6 Z06," said Newman. "That's an increase of nearly 100 horsepower over stock. What we've created is one of the industry's most powerful yet durable and civilized engines. It's a thrill on the highway yet reserved on city streets. Our C6 Z06 is a true 600 horsepower daily driver."

Newman went on to explain that each Street Attack LS7 is hand built by the same technicians that produce championship winning engines for all Katech race programs. Each is meticulously calibrated and dyno-tested before leaving the facility.

Further C6 Z06 engine and exhaust enhancements include a Ron Davis custom aluminum radiator with integrated oil cooler, Goodridge oil cooler lines, high flow air filter, KoolMat race tunnel heat shield, Kooks ceramic-coated headers and a CORSA® 100-percent stainless steel performance exhaust system.

Katech Performance has enhanced the C6 Z06 transmission with a high-performance clutch and an RPM Transmission Stage IV T56 upgrade featuring 300M output shafts, bronze fork pads and cryo-treated, micropolished internals. Stoptech stainless steel braided brake lines and AP Racing Super 600 brake fluid have been added to ensure the C6 Z06 stops as quickly as it starts.

Inside, a Caravaggio hand-stitched steering wheel with a flat bottom, emergency brake boot and shift knob and boot make known the vehicle's elegant demeanor. Here the driver also will find a serialized Katech Performance manufacturer's plaque.

Katech Performance can transform a customer's C6 Z06 upon delivery to its Clinton Township, Mich., headquarters or can coordinate the vehicle's purchase directly through a dealership.
