my brothers 93z just turned 70k miles and is basically stock except the mods in the sig. What is all required for tuneup? plugs/wires (ngk tr55s maybe?), power steering fluid, brakes, coolant, trans, diff, oil, clean injectors, what else am i missing? any help or reccomendations would be appreciated. thanks

 

pcv valve ,fuel and air filters

 

dont forget the small things like checkin air pressure in tires and such little things like that can improve handleing, tire life, and mpg and it only takes a few minutes

 

All the Above Plus:

 

Just want to reinforce the importance that the O2 sensors, should they be replaced, should only be replaced by GM stock.

 

Run a bottle of Techron fuel system cleaner,or you can get them done at Jiffy Lube for like $79.99.Buy a bottle of the "Oil System Flush" and run that through when you do an Oil/Oil Filter change.Use synthetic oils such as Mobil 1

 

awesome thanks for all the help guys, both of us currently run mobil 1 in both our cars/trucks. I was always told never to put anything in my gas tank but 92+octane, so im not sure how those fuel cleaners work. anyone ever hear good things about that sea foam or whatever its called?

 

I run Techron,Amazing liquid!

 

Wow, that's low miles for a '93.

Anyways, I just hit 70k myself and this is what I did recently, or what I recommend:

Change Tranny and rear end fluid. Just use standard ATF for the tranny and the appropriate gear lube in the rear(with the GM limited slip additive).(80W90?)

Flush and refill coolant system.

Check brake pads/rotors

Bleed brakes and replace with new fluid. I recommend ATE TYP 200 from www.raceshopper.com

Check PCV valve

Check Power steering fluid level

Change plugs to NGK TR55's, and hand gap them to "0.050. Don't trust that they are gapped correctly right out of the box. None of mine were.

Fuel Filter

Air Filter (if needed)

A good fuel system cleaner is good to do on a regular basis. I normally go about every 6000k miles and then put in a concentrated cleaner, such as Techron.

Get ready to start saving for a new optispark too

 

hes going to end up doing that coil pack conversion , its his 3rd opti unlike my original.
I dont even have 60k on my 93z. is techron a company like redline? thanks agian

 

Why would you want to send someone to Jiffy Lube to get a service done on a car????? expecially one that someone cares about....GM dealers 60k sercive is Brakes all around, fuel filter, air filter,oil change, diff service,tire rotation..

Recommended tune up from gm dealers is 100,000. which they then replace, spark plugs,spark plug wires,cap& rotor(but most of the time they end up having to replace the whole distributor because the little screws break)pcv valve, timing chain.

Differential is recommended every 30k
trans is every 40K

 

Damn 70k on a 93? My 98 SS has 78k on it...lol
