Hello,

I have the following and am looking for ideas of what a fair price is to sell the car for:

2002 Z06
25K Miles
American Racing Headers
Borla Exhaust
A&A V3 Ti w/1500 miles total (3.4 pulley)
Mantic ER2 clutch w/7k miles total
MGW Shifter
ESC 4.10 Rear w/hardened output shaft
England Green Cam w/proper accessories (springs, pushrods, oil pump, timing chain, etc).
M/T 305/40/18 100miles on them
NT05 275/40/17 100miles on them
611/532 when it worked

Motor let go after 1500 miles of the A&A being installed. I think a ring let go, can hear piston slap, blowby, etc.

Everything works great except the motor. Interior/exterior in great condition.

Thank you in advanced.

How much is it worth to you?

pics and how much??

Sell the A&A kit, and use the money to repair the engine. Assuming the rest of the car Is nice I’m guessing 20k give or take a little. Most buyers don’t want an expensive car that is a project, and few shops can work on them. I’d bet you won’t get much more money for the car with a blower vs without.

How bad is the engine hurt? Does it just need a piston and ring, or is the block and head hurt? I’ve never done a piston replacement with the block in a corvette, but with a two post lift seems like it would be the easiest way to repair if there’s no other damage.

"Sell the A&A kit, and use the money to repair the engine."
I'm with redcycle13 on this one. Good motor you're in the high teens, bad motor you're lucky to get double digits.

I'll give you $20 to take that headache off your hands


Or like other posters said sell A&A kit.

Or, not knowing the situation, save and keep the kit and have the motor built.

interested, pic's ??? price ????

Not having a good motor really hurts the value. The mods and mileage don't mean a whole lot when the motor is no good. Maybe get the motor fixed before selling?

At least pull the head on the affected side to see the extent of the damage. If the head is reusable, a new piston is an easy fix.

Another vote to fix before selling. If that means pulling the blower... well, it'll probably net you more money separately anyway.

Is it safe to assume that it was #7 that let go?

sportmedtech

Assuming the ring gap was not opened up for the addition of boost correct? That being the case you could have broken a chunk of the piston off and the cylinder is need of a rebore or sleeve. if it were me i would pull it apart and do a shortblock at a minimum perhaps the heads too if they are damged. You wont get much for it with a dead cylinder.

I'm curious to know if the car was professionally tuned after the blower install?....The mods are similar to what I'm running in my car...However mine was dyno tuned at ECS and has held up great...551rwhp 13* no meth...I just snapped my WP pulley off and have read a few stories like the one above about stock lower end cars...I've been seriously considering selling my cammed LS1 along with the A&A Procharger kit...Would lk,e to go with a NA 408 or 427 instead...Option 2 is to drive it till it goes boom,,sell the A&A kit,,and then do the swap..

Hello,

Thank you all for the responses. Sounds like I need to consider fixing it before I sell, which means I won't sell at that point. I was hoping it was worth 15K, but if double digits is a dream, it can sit in my garage until I have the cash to fix it.

To answer a few questions:

Yes, the car was tuned by RMCR in CO and lasted 1500 miles before it let go. Car made 611/532 at the wheels. Not a single issue with the car before this.

Yes, I believe it is #7 that is the issue.

I don't know the extent of the damage to piston, cylinder wall, head, etc. yet. I am going by symptoms at this point, which include excessive blowby, backfire, and what sounds like heavy piston slap.

car is garage art not running....a C5 with a running stock motor will get you at best $8-9K for trade in...no one cares about mods....private sale running maybe $15K, again selling a modded car is a crap shoot people are usually worried how it was treated after the mods.....why I parted out my running driving modded C5...waaaaaaaaay more money in it....more work too but certainly way more money

JR-01

Just do the math. Figure out total cost to fix it. You may want factor in your time inconvenience and stress. If its worth $18K fixed and costs $6K to fix and worth $12K as is then it's a wash. Do what's easier for you.

RSbeast

I'm sure there are people interested in the blower

TBH if it were mine, I'd put a short block in it; unless I was having to pay a shop...at that point I would wager my options. A low mile car like that sounds like it's worth fixing right if you wanted to keep it long term.

If it has a bad ring then it probably has a broken piston ring-land. If so then probably a scored cylinder as well. If the groove is deep enough then it will need to be bored out in all 8 cylinders.

At that point you might as well do the right thing for a FI car and go with forged internals (383 stroker). Better yet, a LS3 stroker.

Do a compression test on cylinder 7 and post the results. #7 is the furthest one back in the intake and has a tenancy to run the leanest with FI as the air rushes back. Broken ring-lands are often a result of a lean condition.

What injectors are you using?
