had my 94 z28 for a couple weeks now wondering if you guys know and cheap upgrades i can do thinking about getting a new intake and exhaust and maybe a new chip

2000GTP

There is no removable "chip" on the 94 PCM. A tune would be a good idea though and a mail order tune is the cheap avenue to do so. www.madz28.com or http://www.pcmforless.com/ are a couple of good tuners with a good rapport on here. A cold air intake and a catback exhaust are also very good beginner mods. Not sure what you classify as cheap, but the tune will run around 150 bucks, the catback can run anywhere from the 300-800 range depending what you go with, and the cold air intake can go as high as 200 bucks depending who you go with.

ya thats how much i thought it would be this guy told me to cut off the calatic converter and just run a striaght pipe

How many miles on it? Has everything on the engine and drivetrain been changed or checked? I'd start with replacement of all fluids (oil, tranny differential, coolant and brake fluid) and filters, PCV valve. Check the plugs and wires - it they don't look new, replace them. Check all vacuum hoses for cracks or leaks. Have the PCM scanned for codes.

Make sure you have a healthy foundation to build on. Then start the mod's.

Not a lot to be gained by deleting the cat.

Throttle body coolant bypass is less than $1 for a connector, and good for 6HP.

ya have to take the starter and eveything esle just to change the plus

Injuneer

Not necessarily.

i was thinking about doing the headers and intake because i have none all is the black pipe but no system

2000GTP

I'm a little confused by the wording, but are you saying that you have the intake tube but no airbox?

josefiak3

yep should i throw on a cold air intake

You should put an air filter on it for sure...

josefiak3

what would be the best intake system

dangalla

thats for sure, and i second the opinion that doing the proper routine matinence first is very important

2000GTP

Yeah, you definitely want to get an air filter or something on there. Its hard to say what the best brand is in cold air intakes, it seems to be a matter of preference and they all perform pretty much the same. Check out some of the supporting vendors, you will find most of the parts that you are currently after.https://www.camaroz28.com/links/browselinks.php?c=2
