I have an 03 Z06 which I find to be amazing.

A buddy asked me the differences between the Z and the other C5's. I know most of the differences and started spewing.

Does anyone know of an article in a magazine or another comparison that truly shows the differences, including the differences between the LS1 and LS6, suspension, wheels, exhaust, tires, etc.

Thanks

<QUOTE>the Z06 gets......

Higher lift camshaft yields 5% increase in airflow
Cylinder heads larger ports yield 10% increase in airflow and 10.5:1 cr
Exhaust manifold is cast iron vs stamped steel - flows more, lasts longer
Fuel economy is same as LS1 at 19/28mpg
Z06 specific MAF to help better airflow
Positive Crankcase Ventilation system is upgraded to support high lateral forces
LS6 block is refined to allow higher piston speed and higher overall rpm than the LS1.
Hollow-stem intake valves and liquid alloy exhaust valves are lightweight and help high rpm and high speed operation.
Z06 engine fuel rail covers
Driveshaft is made of a high strength aluminum alloy to better support the higher torque of the LS6
Larger, lighter, safer Goodyear Eagle F1 Supercar tires
Improved brake rotors and calipers
Rear Axle - Z06 rear axle is strengthened for increased durability by shot-peening the ring & pinion to better withstand the torque of the Z06.
Z06 6-speed transmission has straight-cut gears and different ratios to be stronger and to support greater RPM band of the engine.
Power steering cooler prevents fluid from overheating.
Titanium exhaust system - last longer, weighs less
Transmission Temp Sensor to warn of overheating
Z06 FE4 suspension - sways bars, spring rates, and negative camber help improve traction and increase tire contact patch
Larger, lighter, and stronger Z06 rims.
Brake ducts to keep larger brakes cooler and thus safer and more effective.
Mod Red interior
Stronger upgraded clutch
Upgraded master cylinder
Upgraded slave cylinder
Alternate windshield

And it surrenders only the Sport Seats, Fog Lamps, Targa Roof, and CD Changer. Of those, the only two of any importance to me are the Sport Seats that I love and the targa roof.

To me, the Z06 is a screaming deal compared to a Coupe. Imagine what it would cost to add ALL those parts on a Z06 to a Coupe? Definitely a lot more car for the money.<QUOTE>

 

Yes, but starting at some point in 2001, all LS1 and LS6 engines have the new improved LS6 block.

Nope, brakes are the same, except Z06 calipers are red.

No, the gears are not straight-cut, but the ratios are different.

Any C5 with Z51 has the power steering cooler, not just the Z06.

Here's an article by Hib Halverson regarding the diff between ls1 and ls6 for 2001. If you look around on idavette.net you can also find his update for the 2002 ls6.

Thanks, guys. Appreciate the help.

 

Very Detailed article. Here is the update for the 2002 LS6. http://www.idavette.net/hib/02ls6/index.htm

Regarding the brakes: I believe starting with 02, the Z06 has different pads than the other C5s. Z06 pads stop better and dust LOTS more.
