Tune-Up Options

[DIONYZUZ]

Hi my 99 GT currently has 130k on it and has never been tuned-up and has no performance parts on it (100% stock >.<). So the next time I change the oil, I plan to give it a tune-up. What I want to know is what would be the best parts to use on my 5sfe, because I plan on putting a T3T4 tubo in it by the end of the year so I want it to run smoothly. Also If someone could point out what size/syle spark plugs, air filters etc I should use and any other parts I should replace due to the mileage... I would greatly appreciate it. Thank You

Where the hell have you guys heard to replace your fuel pump every year? From all the mechanical training I've had I've never heard anything like that. I've seen 20-30 year old cars on their original pump with no problems, just replaced one on a 1987 Thunderbird Turbo-Coupe the other day and it was the factory pump.

There are varying ideas on how often you should replace your fuel filter, even different Toyota dealers have told me different things on that. One said replace it every 60,000 miles, one said replace it if there's a problem, another said it's a "lifetime" filter and should never need replaced unless there are other problems with the fuel system.

Now for fuel pumps, after 60,000 miles it might be good to pull it out of the tank and make sure the sock is clean (if you feel like being very thorough with the car), but unless it's giving you issues I would just leave it alone. Plus if you've going to be that nit-picky about it you should also drain and clean you tank and probably use a coating inside it like Red-Kote or POR15.

As far as maintenance, has your timing belt ever been done? Timing belt and water pump are a 60,000 mile maintenance item. If you want to do brake lines I'd go for some braided steel lines, and I'd leave the fuel lines alone unless you're having an issue. A big tune-up item on my 99 GT was cleaning the throttle body, I took it off and cleaned the whole thing out with carb-cleaner and it made a huge difference in how my car performs.

You replaced the wires, but not the plugs?
