FS: 2002 600+rwhp, 10.47@133, road race z06

Payne · 11-20-2008, 02:04 AM

I'm finally putting my 2002 z06 for sale. While I am horribly sad to see her go, I dont have the time or space for her anymore, as I bought a supercharged viper. I have been so busy with work these days (and traveling 20+ days a month) that I have not raced her in over a year. I have driven her less than 20 times in the last year, and at least 10 of those were to appointments and errands.

She will average over 30mpg on 77mph on cruise control, and gets about 17mpg in mixed, spirited driving. I took her to Napa for a weekend recently and did 24.3 door to door. Will get under 5mpg on a racetrack

Looking for $27k on stock wheels and suspension, but I'm very flexible on price, as we could do a wildly varying deal, from on stock suspension and stock wheels, to coilovers, 6 18" CCWs, 4 ZR-1s with race tires, etc.

As she sits right now on the coilovers and CCWs:

In action:

Two videos of her at Thunderhill. This track day was 10 hours after I finished the coilover install (Pfadt shipped them late) so I didnt have time to align the car before. I also forgot to empty the catch can on the second video (LS1/6s spit oil horribly above about 1.3gs)

Many more pics below.

The car is a 2002 z06 with 48k miles. She has a 383 w/ hand ported AFR 225s and a baby cam that made 492rwhp/474rwtq and 607rwhp/630rwtq on a 100 shot at Synergy She's been a best of 10.47@133 on a 125 shot, and is a very adept AutoX and HPDE car.

Motor:

383 LS6 built by Texas Speed
TEA small bore AFR 225s
10.7 to 1 compression for road racing on 91 octane
90MM FAST w Nick Williams Throttle body
232/236 .575/.578 114 LSA Cam (car will easily do above 500rwhp w/ a bigger cam
Yella Terra Rockers
Lunati Crank
Diamond Pistons 7cc
Crowerr Rods
ARP Head Studs
Cometic .045 Head Gaskets (.038 Quench)
A million little things: Two catch cans for the 1.4G AutoX, relocated MAP to avoid common FAST vacuum leaks, nice spark plug wires, brand new battery, the list goes on
Mobil1 with a K&N filter after every event, 6 months, or 2k miles (whichever comes first)

Flow numbers of the heads (from TEAs website); a .600+ lift cam would really wake this motor up:
TEA AFR Stage 3 LS1
Lift Intake Exhaust
.100" 68.1 55.1
.200" 141.2 123.9
.300" 207.5 187.1
.400" 261.6 241.1
.500" 304.6 268.3
.550" 323.4 275.4
.600" 341.2 277.8
.700" 346.0 282.2

Cooling:
The car runs safe and cool on even a 116 degree day and AutoXing, never saw above 230 (oil temp). Spirited drving on the street runs about 204-206, and cruises at 100 degrees w the AC on about 194. When other z06s were seeing 20psi oil pressure at idle from heat issues, this one is happy as a clam at 40psi.

DeWitt Racing Radiator
160 degree thermostat
Ligenfelter Oil Cooler (not installed)

Fuel:
Car has a massive overkill fuel system:

Racetronix in tank unit
Kenny Bell boost a pump
42lb Lucas injectors

Exhaust:
This car is loud and mean. See video clips on Thunderhill for sound clips.

Kooks 1 7/8th offroad headers
3" Off Road Pipes
Borla Stingers
stock manifolds and H pipe come with the car
If you want to quiet her down, I can probably get a stock z06 Ti exhaust instead

Nitrous:
Car has a professionally installed nitrous kit. I have only put one bottle through the car, and I believe the previous owner only put 3-4 bottles through her.

Nitrous Express Wet Kit
12.5 Carbon Fiber bottle mounted in the trunk, custom painted red with flames
Hidden switch panel in the ash tray: bottle heater, arm, bottle opener, and purge
Bottle Opener
Bottle Heater
Purge (at the base of the windshield)
Shark Nozzle (have jets, none installed right now)
1 step colder plugs
Window switch

Driveline:

Ram VDS clutch (I love this clutch and have tried at least 6 different LSx clutches in various cars while instructing AutoX)
Built MN6 tranny, with polished gears, steel shift fork, etc... Shifts like butter.
Hurst shifter w/ MGW Knob
Remote clutch bleeder- this is a godsend. Its a 10+ hour job w/o to bleed the clutch, vs 15 min.
Built z06 rear end with both output shafts 300M, and a tighter posi (hooks a lot better on tight, slow corners)

Brakes:

stock brakes w/ many different pads coming with the car: stock z06 pads for no dust, HP+ for street and AutoX (currently installed) and Carbotech 10/8 F/R for HPDE (zero fade!)
C6Z06 front brake ducts with ultra high temp Silicone hoses
Stainless brake lines
Tech II bleed with Motul 600 fluid

Suspension:
More than the motor and the straight line go fast, what really sets this car apart is how well set up she is on the road course and AutoX. After driving this one on the coilovers and poly bushings, a stock z06 feels just sloppy and ultra pushy.

Pfadt Racing coilovers (16 way adjustable)
Car is slammed, much lower than possbile on the stock suspension (the Pfadts have a much higher spring rate and are a much shorter shock, so you dont bottom out like lowered c5s on the leaf springs)
all suspension bushings replaced w/ poly
We spent about 16 hours installing these. 6 hours alone shaving and polishing the bushings so that they dont bind. Every other C5 w/ them bind badly and squeak horribly, where is mine is very quiet
Perfect cornerweight and allignment with me in the car (195lbs)
Stock z06 front sway bar, no rear bar installed
very agressive alignment, 2 degrees of negative camber, maxed out castor, a little toe out up front for better response and turn in
I cant stress enough how many hours I have in allignment, cornerweighting, and coilover adjustment to get the car perfectly neutral
Car is perfectly neutral on 315s on all 4 corners, has just the slighest push on the street tires (295 and 315), for a safer street drive

A million Misc things:

HID Low Beams
linelock
short antenna
trailer hitch and wiring for a tire trailer (hell, you can have the tire trailer too for free!)
MSI Roll Bar/ 6 point harness mounts
Harlan Shift light
Lloyds Floor Mats
Foam trunk partition with 'Corvette' embroidered in Red
Both Euro and stock taillamps

That's most of the major mods to the car. I try to be a super honest seller, and will give as much disclosure about the bad of the car as well.

This car is not a show car, or a garage queen. She has been raced, a lot, even in the rain, she has done 3-4 HPDE and has the rock chips to prove it. She does not need paint IMHO, but if you are expecting a perfect car with no blemishes, this is not the car for you. If you want an extremely well sorted car with a LOT of money invested in her to go fast in all types of racing, this is the car for you.

I got rear ended by a 2500 Diesel at about 5mph in stop and go traffic, and it scuffed the bumper and chipped the fiberglass on the driver fender. Probably 1.5"x.5".
I ordered an OEM black bumper from Corvette Recyclers, and have replaced the bumper and fixed the damage. I have pictures to show all of this. You would never know, looking at the car, but I want to be 100% honest with the buyer
There is a 1/2" tear at the seam of the outside bolster of the driver's seat of the car, the result of a Synergy mechanic getting out of the car while doing a Tech II bleed
The foam partition has a 2"x2" shaving in the back for the automatic bottle opener
The rockers do have some war wounds from being ~3" off the ground, but you have to be less than 12" off the ground before you see them
The front does have rock chips in the bumper, and there are scuffs under the radiator on the front subframe
There are a few minor scratches from a blowout, I will post picture
I know this makes the car sound like a disaster, I can assure its not, I just want to let every issue I am aware of be known
That being said, there is NOTHING mechanical wrong with the car that I know; I would not hesitate to drive it tomorrow to Alaska, or straight to the dragstrip, AutoX, or HPDE.
