Katech-Modified C6 Corvette Z06 Available for Purchase

Corvette Z06 with the Katech Stage 1 package picks up nearly 100 horsepower, but it looks all original.

Katech is best known for building engines for the legendary Corvette Racing endurance program, but the Michigan-based shop also offers performance upgrades for street cars. For example, Katech offers an upgrade package for the C6 Corvette Z06 that adds more than 80 wheel horsepower with a few upgrades. The factory look is maintained in the engine bay and the car can still comfortably be driven every day, but it packs considerably more power.

A 2009 Corvette Z06 with the Katech Stage 1 kit has been posted for sale by “Kevin Nevius”. This same car was actually showcased on the forum by Katech when it was built back in 2017, so we have the full details on the build. In short, it has an aftermarket camshaft, a cold air intake and a tune, and it is making roughly 600 horsepower at the crankshaft. It also has aftermarket wheels and brakes, making it a more formidable track car, and it could be yours.

Katech Corvette Z06 #95

When the owner posted his 2009 Chevrolet Corvette Z06, he shared the picture above, along with the information below.

I would like to sell my 2009 Z (Katech stage 1 package, serial number #95), serious inquiries only please.

In addition to the Stage 1 Package, Katech upgraded the brakes (ceramic pads and new Racing Brake rotors), and added Katech Forgeline Wheels (black) and TI lug nuts (and new Pilot Sport non-fun flat tires). Also included are the original silver painted Spyders (with almost new Michelin PS run flats).

All work was completed in 2017 (22k miles). The car currently has 27k miles, and I just don’t get a chance to drive it very much anymore. The car is remarkably clean, stored all winters.

The OP also shared a link to a thread posted by Katech back in 2017 with all of the information. As you can see in the dyno sheet, this Corvette picked up around 82 horsepower and 49 lb-ft of torque at the rear wheels. We can also see that in stock form, it “lost” about 15% of its power from the engine to the wheels. Using that same 15% factor, this Z06 is making around 601 horsepower at the crankshaft. That is nearing a 100-horsepower gain from an intake, camshaft and tune.

Katech LS7 Packages

Katech currently has two “stage” kits for the C6 Corvette Z06. Stage 1 includes a Halltech cold air intake, a ported throttle body, a “competition” valve job and a custom engine tune. The goal with that package is 550 horsepower. The current Stage 2 kit starts with all of those items and adds a camshaft, ported cylinder heads, a new intake manifold and many supporting components. The goal with that package is 650 horsepower.

Back when this Corvette Z06 was built by Katech, their package varied a bit. This Stage 1 includes a camshaft, a Halltech cold air intake and a tune, yielding the 600 horsepower mentioned above. It appears that this kit is no longer offered, so if you want this form of Katech C6 Corvette, you might want to seriously consider this one.

Even if owning a Corvette Z06 built by the folks who have been responsible for LeMans-winning race engines doesn’t mean anything to you, buyers can be confident that this LS7 was built correctly.
