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

i would call art at partznet (there is a sticky at the top of the general discussion page with his info), and tell him what you have, and what you want to do. he will give you everything you need to get the job done right with OEM parts (which is hard to beat, especially when it comes to ignition and tune up parts) at a great price.

change your spark plug wires, but if i were you clean you engine first so you wont ruin new spark plug wires, then get some spark plugs, bunch of ppl go for ngk spark plugs idc really. do a fuel pump, fuel filter, k&n is a good filter, its whatever you like honestly.. thats just the basics of what id do. if you have time bleed your break line, if you wanna go that far. meh, i did all that, and then i drained my power steering as well, like i say its whatever you want

most of that sounds like a bad idea IMHO. Unless your car is losing major power, I wouldn't replace your fuel pump; even if was, you should check your fuel pressure first before you go replacing things. No need to bleed your brakes unless your pedal feels really spongy, or just doesn't feel like brakes should. NGK spark plugs are good, fuel filter is often the forgotten filter, so I'd say that's probably a good idea. With spark plug wires, often the damage done due to wear and tear isn't actually visual; it might be internal in the wire without a visual sign or break. K&N is always a good drop in filter, but will run you about 40$, but honestly, for most of the other stuff, OEM is the way to go, like Presure2 said.

well your suppose to change your fuel pump and filter once ever year or so, and our cars being that old it might be a good idea ya know

Ehh, I'm more on the line where i don't replace something unless it's broken. or close to that point, because usually when I do that, it breaks something else.

And plus, a fuel pump is not part of scheduled maintenance. Unless your filter is clogged to the point where it's making the pump work twice as hard, it shouldn't ever really need replacing. (unless it's just deteriorated)

[DIONYZUZ]

Thank you all very much... I went with the K&N Air filter (the reusable washable one) and some bosch spark plug wires. I think I will replace the fuel pump, because of the mileage on the car. I did want to get new fuel lines and better brake lines as well to get the car running like new.

fuel pump and filter should be serviced every 60,000 miles.

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?
