found a good deal on a 93 z28 with around 80K for 2500.00. all stock and never touched. only thing is that is has the automatic, now i do plan on moding the car but i was just curious if i would be wasting my time becuase its an auto. i want to compete with my 05 gtos, 99 vettes, evos, wrxs , srt 4, stuff like that but i dont want to dump a ton of money into it, so i do plan on using some spray, this is just goin to be a playtoy so im not driving it everyday, im actually just trying to find somthing fast and cheap and saw this even though its stock but seemed like an ok deal...what do you guys think?

My 97 z28 is auto, granted its not as fun as a stick, but it still hauls ***. Buy it and mod that ****!

The manual cars tend to break rearend components MUCH more easily, the auto is much less likely to do so.

The 93s are not as easily tuned, they are speed density so the actual tuning is harder too, they have an unvented opti. The tranny is harder to tune because it is not computer controlled.

On the plusses, the intake and heads are both great starting points for a performance build and I think the ECM when reprogrammed allows it to rev pretty high, but higher than you can take stock parts.

The auto tranny gets a bad rap because of bad builders simple as that, when Joe blow down the street tells you he can build it he is probably lying. I have seen "reputable" builders use proven kits and only get a few hundred miles out of a tranny. Few guys actually know how to do it and put the care and effort into getting it all right. Once you use one of those guys though you can have a tranny that will last into the 9s in the quarter.

Your going to be spending a buch of money if you plan on running with the cars listed. If you do the work yourself it will be a lot cheaper. If the engines in good shape and you only want to spray it would be the cheapest route. Figure $1000-2000 for a good setup done right.

Exactly, whether the car is a 93 or a 97, a manual or a stick, those cars listed are tough to go against. You will have to put some money into the car either way to get it to compete with some of those, especially the turbo AWD ones. Just because it is an automatic tranny doesn't mean it is going to be slow and counted out. Put a higher stall converter in there and you will really wake it up.

hmmm, guess it has its ups and downs, what about simple bolt ons(intake,exhaust,TB,any other simple cheap mods) and a 100 shot, where do u think that would put me? 1/4 mile wise?

what is a unvented opti?

11secgen

low 12's with a gear,stall,headers and 100 shot.oh, and you have to use a wet shot on a speed density motor.later opi (the lt-1 distributor) has a vent line going to it to help clear out any moisture.the best first mods for these are stall, gear, headers and tuning.

2000GTP

Bolt-ons and a 100 shot would put you somewhere in the 12s assuming good track conditions, driver ability, a good running car, and how in depth you go with the bolt-ons. The non-vented optis were in the earlier LT1 motors 92-94 before the vented version came out in 95. The vented version had a vacuum line connected to it that circulated air helping to protect it from the elements.

what gears,what stall,what kind of headers?

2000GTP

3.73 gears and a 2800-3200 stall are popular for bolt-on street cars. As for the headers, there are alot of options. What kind of emissions regulations do you have to deal with?

The trans in the 93 is a 4L60, not electronically controlled like 1994+ cars. 93 Autos because of that don't run in to the OBDI stall wall, I have run a 3200 in mine for years and its fine. On the down side you can't adjust the speedo after gears via tuning, you have to swap the drive and driven gear in the tail shaft. There are a lot of great tunners who can set the 93s up, PCMforless did mine. Most the combinations people run are the exact same or really similar so getting a good tune really isn't that big of an issue. 93s run a non heated O2, FastBird sells a conversion harness, I ran the non heated set up with Hooker LTs but ran in to O2 and idle issues, switched to heated and never had a single problem. I still have my stock 3.23s, but with an auto 3.73 is a good gear and the most you can correct the speedo for with stock tire height via the drive/driven gears. Six speed 93s use a calibration box, you can get them from a nmber of palces, havent really seen any one do that with a auto. Far as Headers go, just depends on emissions and if you have to pass. Far as the opti being unvented, so are 94 F-bodies, you can convert to a vented opti just the same as you can with a 94.

what brand stall and gears? what kind of prices are we lookin at? as far as headers ill need emissiopn legal headers, what the best and cheapest? thanks for the help, still thinking about picking up the car....2500 is a good price, havnt looked at it yet tho....

2000GTP

Might want to try the search feature, there are many different vendors and options for each of those modifications and plenty of good information covering them. Costs will vary depending on what brand you go with. As for the headers, there are several different styles and brands you can go with that are still emissions legal.

take a loan out using the 2500 as a down payment and buy this car. https://www.camaroz28.com/forums/sho...d.php?t=583688
