Default How much to pay?

93 Z-28. The car is truly like new in appearance inside and out. It has 94,000 miles on it. Was wondering what I should offer?

Auto, 6speed? Wich rear (2.73's or 3.23's) and trans (M28 or M29 - 6 speeds). Those dont mean much in value but make for a more desirable car. I would say 3900 on the top end. 3350 would be a good middle ground

not more than 4 but I wouldnt pay over 2500 for a car that old. Do your research b4 you buy an LT1 car know what your getting to. If you want to just do boltons and be fast I would not suggest getting one.

Something like that would go for around 3,000-3,800 around my area.

agreed, $3000-$3600 range would be a fair price. As far as the bolt ons comment above...you can still make it a 12 second car for less than $7500 total including the price of the car if you pay around $3500 for it.

O.K. so I can get it for 3500=3800. What bolt ons are going to be the most beneficial in terms or quickness. My plan is to street/strip the car. Cost aproximately. Goal for the car will be somewhere in the 12s.

well i am biased here but a 1993 LT1 (especially a Z28) is/was the best LT1 fbody ever built!! LOL

seriously though, the auto could have either gear out back. I "think" the 3.23 rear gear car has PRND21, but i am not sure. 1993 has a few differences that the 94+ cars. the car is Speeddensity (no MAF), non vented spline drive opti (93-94 use this type), the ECM is a EPROM "chip" computer that makes tuning different that 94+ cars (still obd1 though), and a few other things.
Check out this:
http://www.speeddensity.org/showthread.php?t=679

I love my 93. It by far has responded to many minor mods better than other LT1 cars i have worked on. My car has 60K (papmered) miles. 94K is good too, but be aware it is still 17 years old and there will be normal maintance issues. For instance all my rubber pieces were shot when i got the car. I say take the dude somwhwere above 3 grand and see what he says. Is not like the market on these is great right now anyway.

Good Luck!

I am 13.0 - 13.2 with all bolt ons on a decent tire. I am not good a launching a 6 speed. I cant crack a 2.0x 60'. Bolt ons and some spray will get you 12's. I got about 2000 in parts (used and new) tied up in mine for performance and suspension. I have about another 2 grand in "appearance" mods. I paid 7 grand in 2002 when the car was 100% stock and 38K miles.

high 12s are easy if thats what you want.
LTs,ORY-500.00
cat back-200.00-800.00
mail order tune-175.00
52mm TB-250.00-350.00
free mods-free
CAI or LS1 lid-250.00
good tires-350.00
stall,gears-(im not sure how much stalls cost)
LCA,PHB-175.00-250.00

Im sure im missing some things but thats pretty much what I have + or - a couple of things. my times are in my sig I could be in the 12s with a good launch.

A 93 is unique in a few ways, including:
The transmission is a 700r4/4L60 (no e for electronic control)
You can't flash tune the PCM, it has a chip on it which has to be replaced/reprogrammed
You have no MAF, so you have a Speed Density tune, which many tuners will argue is the better way, including a quicker throttle response

Most likely the rear gear is a 2.73. 3.23s were for "performance packages". The only real way to check is the RPO code on the driver's door. IDK the codes, but the Gearing section in this forum will be able to tell you.
Stock, it is a low to mid 14s car.
The weak points are the 10 bolt rear and the 4L60, but for your goals they should hold up. Autos are easier on the rear, thank god.
For the rear, I would upgrade to a 3.73 and a TA girdle.
For the tranny, I would put in a TransGo HD2 shift kit.
A 3200-3500 stall would be good, but not cheap. Expect to pay $500-700 for a quality unit. You don't want to go cheap b/c if it goes, it takes the tranny with it.
And most certainly install a transmission cooler no matter what. When you do, take the radiator "cooler" out of the loop.
Engine and suspension mods listed by 97camaross are good, except I would add a good quality adjustable torque arm from UMI or BMR.
If the Opti needs to be replaced (not uncommon) go vented. Much better design and not difficult to do.
I would look into converting the PCM to a 94-95 style, which is flash reprogrammable. Not sure what is involved, but it is far easier to work with. And expect a mail-order tune to get you into the ballpark, but leave hp sitting on the bench since each car will be a little bit different to tweak.
Best of luck.

Thanks for the help guys. I am still trying to find a good F body to buy. Right now I am not having any luck at all with the 93 as he is convinced he can get his price of 4350 for it. I just know I am gonna have to spend a bit more to get it to where I want it so I won't go that high. I will keep looking.

Look up the Kelly Blue Book Private Party price for that car and print it out and show him the paper. If anybody buys that car for that price, they are stupid

the only 1993 camaro worth a good amount of money would be one of the 19 1LE cars or 1 of the 633 Indy Pace Car replicas. My friend is trying to sell his indy and having a hard time even..

I'd keep in touch with him and stay firm with yur offer...he'll come around, and if not...you don't wanna buy a car from someone that unlevel-headed anyway.

FWIW, I paid $4K for mine about 6 months ago. 93Z, green gray metallic, A4, 3.23 rear, cloth seats, hardtop, and only 88K miles. Personally I think I got a steal, but that's just me. Paint is a 10 footer but it was stored most of its life.....and now it's my DD

FWIW the rear axle codes are GU2 for 2:73 and GU5 for 3:23.
