If I am not mistaken the 00 has 385 horse and I'm not sure how much torque, the 01+ has 405 and 400 torque I THINK. My question is this, how easy is it (and expensive) to make up those 20 horses that the 00 lacks. What did Chevy do differently to the 01 to give it that boost? I am trying to get another Vette (currently have a 64 Vette :D and an 01 V6 Mustang :( ). Thank you guys!

Um, well if you are being serious I will post before someone else blasts you. There were no 00 z06's made. The z06 started in 01. In 99-00 they were called the FRC (fixed roof coupe) but still retained the ls1 engine and power ratings. The 01 Z came with 385hp, the 02 came with 405. To answer your question about what makes up the difference in power, different cam, no pup-cats, no screen on MAF, lighter valves, etc.

If you're looking for some serious power then I would get the 01 model. You can find it cheaper and with the extra $$ you save you can make more power than you would have with the 02. Just my .02 though. :thumbs:

:iagree: ...there are alot of great deals on the '01's! You could pick up a nice '01 and have lots of $$$ left for mods! :)

gmblack3

Adding an intake and catback exhaust you get you in 02 territory. See my sig.

Sorry for my ignorance, I know very little about the newer Vettes. Thanks for filling me in guys! It looks like 01 is the way I will be going as I have some pretty good deals going on in my area! WOO!

i picked up an 01 z06 for 28,400 :smash: :smash:

only 15k on it has 18 now :)

Here is a little more of the differences in the '01 to '02 Z06. There was more than just the 20hp increase. The 20hp performance difference in the LS6 engine was only worth 1/10 sec 0-60 and 2/10 sec in the 1/4 mile. I would also recommend going with the '01, as it would be a bargain. You can get back the 20hp and make other changes to the 2001 to get very close to the 2002 specs. You can even add the HUD to your 2001.

New for 2002 Z06

LS6 engine receives 20 horsepower increase, to 405 hp, and receives 15 foot pounds more torque for a total of 400 lbs. ft. of torque
Pre-cat deletion
Revised rear shock valving
Aluminum front and rear stabilizer bar links
Aluminum transmission cooler case
Z06 wheels are now cast aluminum, not forged aluminum
Head-Up Display (HUD) now standard
Cam/Valve/Spring change

This upgrade to the LS6 engine's output is the result of new hollow stem valves, a higher-lift camshaft, a low restriction mass air flow (MAF) sensor and a new low restriction air cleaner design. Eliminating the PUP converter from the exhaust system enables better flow of spent gasses and reduces vehicle weight, without compromising Corvette's NLEV (National Low Emission Vehicle) status.

Suspension Upgrades
The Z06-specific FE4 High-Performance suspension system features a larger front stabilizer bar, a stiffer rear leaf spring and specific camber settings - all calibrated for maximum control during high-speed operation. The 2002 model year Z06 also has new rear shock valving for a more controlled ride.

Although retaining the same design and color finish, the unique aluminum Z06 wheels are now produced using a cast rather than a forged process.

Additional Refinements
Now standard on Z06, the Corvette's Head-Up Display (HUD) projects vehicle speed and many other gauges digitally on the windshield ahead of the steering wheel, enabling drivers to keep their eyes on the road.

For 2002, the transmission cooler case is constructed of lightweight cast aluminum, replacing the previous stainless steel design.

The clutch of the 2001 Z06 had already been enhanced to deal with the increased power of the LS6 (over the LS1); with the additional power of the 2002 LS6, a new clutch design was developed to ensure long life and good performance.

LS6 Clutch Improvements
To withstand the greater torque output of the new engine, the LS6 clutch was redesigned. Clamp load has been increased seven percent and durability has been augmented by the following enhancements:

The clutch-driven disc was redesigned, with the flange plate thickness increased by 20 percent - from 5 mm to 6 mm . The damper springs were redesigned to increase wind-up rate, from 33 Newton-meter degrees to 35 Newton-meter degrees . Premium alloy steel wire is now used for the damper springs.

These changes ensure long life and good performance for the LS6 clutch.

The valving of the Z06's rear dampers was also revised, allowing for smoother, more efficient transfer of the additional horsepower and torque to the pavement. "Revising the damping allowed us to improve the track performance of the Z06, as well as its everyday ride quality," said Mike Neal, Corvette ride and handling development engineer.

In addition to generating more power, Corvette engineers also scrutinized every possible means to reduce vehicle mass, which in turn results in improved vehicle handling. Their efforts resulted in:

Cast aluminum front stabilizer links (versus rolled rod steel links), resulting in a 0.2 kg (0.44 lbs.) weight saving
Cast-spun aluminum wheels (versus forged aluminum), for a total mass savings of 0.6 kg (1.3 pounds)
These are further enhancements to the world-class FE4 suspension system that debuted in 2001.

Greater emphasis on performance is further enabled with a standard Head-Up Display (HUD) for 2002 Z06 models. It provides critical vehicle information - including tachometer, vehicle speed, oil pressure, coolant temperature and fuel gauges, among others - promoting a "hands on the wheel, eyes on the road," philosophy.

The new LS6 V8 delivers 405 horsepower at 6000 rpm and 400 lb-ft of torque at 4800 rpm. To achieve this additional power the engine received modifications including a revised air cleaner housing, low restriction Mass Air Flow (MAF) sensor, lightweight valves, higher lift camshaft and an exhaust alteration.

The component modifications that enable the additional 20 horsepower and 15 lb-ft of torque (compared to 2001) all focus on getting more air into and out of the engine. Increasing the volume of air in and out ultimately creates more power.

Air first enters through the air cleaner housing. The new air box opening to the air cleaner increases by approximately 6.65 square inches (43 cm2). This additional Volume contributes to more horsepower.

The new MAF sensor no longer has pre-sensor grid work known as air channels. Induction air thus flows less restricted through the mass air flow sensor and into the intake manifold.

Gases flowing into and out of the combustion chamber pass by new hollow stem valves. The stems of the exhaust valves are filled with a liquid sodium alloy. Since the exhaust valves operate at a much higher temperature than the intake valves, the liquid alloy enables better transference of heat from the exhaust valves to the valve guides and then to the engine coolant. The valves reduce valvetrain mass by approximately 368 grams. This lighter weight allows the valves to keep contact with the cam at higher speeds.

The new cam profile is the greatest contributor for the increased power. The new profile allows the intake and exhaust valves to open .7 mm further. This key change enables more air to be pumped in and out, which equates to more power. Each camshaft is induction hardened and straightened to an accuracy of ten microns to ensure it spins true in the engine. All 16 lobes are inspected using opto-electrical technology with submicron level precision.

For 2002, the ZO6 will eliminate the use of dual pup catalytic converters found immediately downstream from the exhaust manifolds. Eliminating these converters allows for increased exhaust flow out of the engine. The under floor catalytic converters have been modified to make up for the pup converters and still meet NLEV emissions standards.

Great post TexasRedZ06. It's amazing what people on this forum know. :cheers:

:skep: what kind of condition was it in?

dvandentop

perfect shape nothing wrong with it at all!

Cobra4B

Holy crap Davandentop!!! I thought I got a great deal 11k for $34k, that's the best I've ever heard of. What's the catch, someone need money in a bad way?

dvandentop

they guy really wanted to sell it to get a boat he was asking 30 to start off with but someone else offered 29 and he said yes but then they couldnt get financing so i offered 28750 and he payed for my plane ticket to come get it :)

Me not that smart :crazy: I just Cut-n-Paste from various sources. I can't even remember my license plate number on the car, let alone what changes were made year to year. :lol:

I wonder what would happen if you added that to an 02?

I fixed your topic for ya.........changed the 00 to 01 and the 01 to 02 :)

thanks
