Definitely not. That would slow down the air flow. Your car would sound louder but lose power. As a bare minimum it needs smooth tubing with gentle bends and a good air filter. No way around spending more money for a decent intake. The engine is a big air/fuel pump. The more air/fuel (at the optimum ratios) = more power. I think you need more like minimum $200 on up to $500 for the best. Ask people in the Modifications forum what ones they have used with good gains. Especially ones where they have gotten before and after dyno results. More noise does not necessarily mean more power.

Clean air filter. Premium fuel. New spark plugs. Proper tire inflation. Upgrade tires when the old ones are worn out. New sway bars and/or polyurethane bushings. Sport shocks when old ones are worn out. Polyurethane steering rack bushings if old ones worn. Window tint. Fuzzy dice. Push the PWR-ECT button.

Alas, technology marches on. Think of it this way; a 2000 Camry only has 194 hp. And while it's true, more power = more fun, personally I'm having a lot more fun driving a classic than a "there's one in every other garage" car.

All depends on how much you are willing to spend (money and/or wrenching). Be aware, the minor mods only give minor (if any) power gains despite what the marketing people claim. A poorly designed aftermarket part can actually cause a loss of power! Especially the cheap "one size fits all". A true performance part has to engineered for a specific application. If you can give a budget, people more knowledgeable than I am, can give you some ideas. Check out the Modifications forum too. Good luck on your quest!

Good to think ahead! A lot of mishaps could be avoided with a little forethought. Bravo! ;)

Have never tried Seafoam, but we had a more fun cure for carbon - find a long stretch of open road, preferably up a looong hill, pedal to the metal and smile! Probably best to do on clean oil since the engine will need good lubrication. I couldn't find any reference in my owner's manual, but a lot of modern engine manufacturers specifically state not to use oil treatments or additives. FWIW, after changing spark plugs at 70k mi., I'm getting 2 mpg. better. B) Edit: Come to think of it, they also did a Fuel Injection Service. p.s.

Glad to hear you are enjoying your Lex! Lexus recommends rotating every 7500 mi. but it is not super critical to be done exactly on time. Rotating them evens out the wear and makes the tires last longer. If you look at the side of your tires, if they are directional they will have an arrow or pointer showing the direction of rotation when driving. (of course don't try to look at them while you are driving, you might get a sore neck or bugs in your hair or something) :P

Did he look up the specs on the particular rims you want? Without knowing width, offset, and tire size he could not truly determine if they will rub. You would also get lower profile tires to keep the overall diameter within specs for your transmission, so that wouldn't be an issue. Low profile tires do have stiffer sidewalls and will ride rougher, relatively speaking. Here is a link which shows the relationship between offset, width, and tire diameter: Wheel / tire size calculator. For example plug in 215/60-16 16x7 ET38 and 225/40-19 19x8 ET32 you can see the diameter is the same and clearance on the inside is the same. Since I don't know the actual specs on the wheels you want, this is just for educational purposes.:whistles: TireRack lists plenty of 19" wheels for our cars: TireRack. Whatever you buy has to have the same bolt pattern 5x114.3mm and use a 60.1mm hub centering ring.

I like to look at pricing from both Kelly Blue Book and Edmunds private party values. They will differ, pick the one you like better. ;) Usually major service is at 60k mi. You might want to ask to get this post moved to the IS forum for more advice. Good luck hunting!

Look for a cat back system. = all the pipes and mufflers past the catalytic converters. Drilling holes can cause exhaust to come into the car interior, plus if you are in an area subject to emissions inspections you may get fined. :o

No. :o

Yes you do have to remove the power steering pulley.

Wow! I can't see how she could reach the pedals? :D

Maybe your springs are not cut, maybe lowering springs from Intrax? Intrax And no, I don't have any wisdom, but a lot of guys run Tein coilovers: Tein Prices They sell lowering springs too. As far as wheels, Zippyguy gave awesome info on fitment. For style, I'm not good at visualizing so all I can suggest is look at as many pictures as you can find until something jumps out.

Repair Manual After you get to Auto Repair Reference Center: 1993>Lexus>GS300>Repair Procedures>Engine Performance and Tune-Up>Engine Electrical>Alternator ;)

Where's a good source for brushes? :)

Service Manual Takes a few steps to get there, but they do have strut and spring replacement procedure for 2nd Gen GS400. I think the only specialty tool you need is a spring compressor. (Use with caution!).
