What can I do to my 98 Avalon to... make it go really really fast?

totally. hopefully he posts some pics after he installs a twin turbo, roll cage, and nitrous oxide😉 a fast avalon, now thats a sleeper😉

If I ever feel the need for speed and drive it off a cliff, then I'll need that stuff. 😉

Well, nice alloy wheels help any car. Nice paint . . . and lower it . . . lot's of stickers and a big ass exhaust and a big spoiler. A bad ass sound system and a gorgeous chick are also really improtant. Speed? . . . well then, you'd need to learn to race . . .

😀

I hate (well, not really) to break it to you . . . but some cars were never intended to be modified. Your Avalon is near the top of the "do not modify" list. It CAN be done . . . but then some things should be a crime.

EDIT: I hope you realize I am j/k'ing. Your topic title says you want to go really really fast and then you contradict youself in the first post by saying you DON'T need to go fast. Seriously, if you don't have them already - a nice set of wheels really make a statement on ANY car. If you need a bit more horsepower, simply modify your onboard chip and improve the exhaust flow. If you need to corner better, tune your suspension (ask the shop about your model).
And if you are really serious about racing, learn to drive professionally and buy a real sportscar.
 
how about just a K&N air filter to start with ... not too expensive ... gain a few HP and a bit of torque ... easy to install
 
Cold air intake, K&N air filter, cat back exhaust, and maybe check around and see if an ECU chip is available for your car. All of these could probably be gotten/installed for around $1,500 and if all are available for your car, you could see a gain of anywhere from 40-80 hp depending on how your engine was originally tuned at the factory.

This thread is crackin' me up. Everyone is saying 'Avalon, not worth fixing up' 'not meant to be' 'shouldn't be done' yadda yadda yadda.

But in this guy's original post he mentions finding all kinds of parts for Accords, Altimas, Camrys, Corollas, etc. Like those cars are worth fixing up and making them go faster. Bah, I say.

I'd rather be cruising around in my Avalon any day, than one of those other cars. (Mostly cuz I wouldn't fit in those other cars, I'm 6'7")

Actually, I'd rather be cruising my 😎67 Riviera😎 all day long, but that's another thread. . .

Yeah, you're going to get 80hp from a couple metal pipes that dont even run all the way to the engine

I probably won't be reselling it. I'll be keeping it until I drive it into the ground. 🙂
 
There is only 1 real way to make cars go "really really fast", put more AIR and FUEL in the chamber.

Blower/Turbo/NOS

I have an exhaust to flow better to cool down my motor, the performance gains of the exhaust are very minimal, but the overall benefits from cooling are what I like, Cooler motor = lasts longer, better under hood makes other parts last longer, also makes it so the engine fan turn on less so it doesn't rob power, also cooler block = more power.

The K&N Gen 2 Filtercharger, no increase stock, but with my blower it made it so I could get 1 extra pound of boost.
 
It all depends on the space under the hood. If it's not too tight, you can add a sequential turbo (you need drivability for this car, not top-end). You'd need a blow-off valve, a boost controller, new oil lines, all that intake piping, an optional intercooler, and a wastegate if the turbo doesn't come with one.

With extra boost comes the additional difficulty of firing off the stock ignition. MSD/Crane distributor-less ignitions are excellent - you'll need new coils, and maybe spark plugs. Fine-wire iridium spark plugs will let you fire easily, but they are costly. I'm no expert on Avalons, but the spark gap should stay below .05", depending on boost level.

Additionally, if boost levels are high, you will need a new fuel pressure regulator, and maybe a new fuel pump. Higher-flow fuel injectors will also be needed if the engine is constantly running lean.

To take advantage of all this, you need a modified ECU. Go to a shop that does this.

You'd then want a mandrel-bent exhaust to reduce backpressure (no matter what ANYBODY tells you, BACKPRESSURE IS NOT NEEDED AT ALL!!!), preferably with a diameter of over 2.5", and a straight-through muffler. Magnaflows are nice - and they don't sound like a wacked-out 2-stroke lawnmower. Go for the oval stainless steel ones.

Porting the areas where air flows is costly, and to many people, just isn't worth the price. However, a custom cold-air intake situated near *cough* a 'custom' hole in the fender well would do well to free up some asthmatic flow.

Contrary to what somebody in this thread said earlier, DO NOT disconnect the compressor. The Avalon is a family car and should stay that way (but you can make it faster. 🙂).

On the handling side of things, install bigger vented & slotted brake discs. Brembo kits are nice but costly. Switch your brake pads to EBC Greenstuff pads. Excellent stopping power with very little dust. Then you'd want to pick up lightweight forged aluminum wheels with low profile tires like BFGoodrich g-Force TA/KD[WS] (depending on weather), to reduce unsprung mass and to improve steering response. However, you should end up with the same outside diameter of the wheel, or else you'll have to replace the speedo and odometer. BTW, the thinner you go (sidewall height...) the rougher the ride will be.

Coilovers will let you lower the car for a lower CG, but too low and you will be classified as a ricer 🙂. These are totally optional.

Aerodynamics? You don't need any. Please don't put a wing on your beautiful car.
 
Axis Se7en wheels look great and are pretty light, but at $240 apiece for a 17" tire, they're not the least expensive ones.

It's not that the Avalon isn't worth "fixing up". It ALREADY is a nice car - it's just not the type of car to "rice". Nice wheels, a good paint job and maybe a little boost to the HP is more than enough. Plus, unless you plan on keeping it forever, you have to think of resale or trade-in value.

You forgot a killer sound system! (Hence the nic)

I mentioned it in a previous post. It seemed so obvious (and redundant). 😀
