Draining A 2002 Gs430's Torque Converter
Vette Boy replied to Messerchmidt's topic in 93 - 05 Lexus GS300 / GS400 / GS430
The TC hold 1-2 quarts max. If you want to replace all the fluid, power flush. -
Gs430 0-60 Performance Not To Spec

Gs430 0-60 Performance Not To Spec
Vette Boy replied to cpr_carpenter's topic in 93 - 05 Lexus GS300 / GS400 / GS430
Yes, to get the best times, you'll need to be PWR mode with VSC off. As noted, TC is torque converter. It's the clutch of an auto trans. By loading it up to the stall speed you eliminate any delay in spooling up the drivetrain. With a little practice, you'll max out the number, whatever that is. Meeting magazine nunbers on an auto trans is much easier that a manual. I've been able to max out my old Imapala SS with auto trans, with my manual trans Vette, I'm a 1/2 second slow in the quarter mile, after 6-7 trips to the strip. -
Gs430 0-60 Performance Not To Spec

To get a good launch without spinning the tires: At a complete stop, brake hard and load the TC up by reving the engine to ~1500 RPM (right under the stall speed of the TC). If you have to much gas, the rear wheels will start breaking loose, back off slightly. At the same time, release the brake w/left foot and roll into the throttle w/right foot. This is the part that takes skill. If the throttle is just mashed, then the tires will spin and the time will suffer, if it's not rolled into fast enough, the max performance isn't realized. -
If you go to lexus.com and join the owners area, you can download the manuals for your car. That's the only place I can get a nav manual for my '02 (unless I pay the dealer $20).

Front End Shimmy Under Hard Braking?
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
What's a good brand? I see rotors on-line for ~$120 a set. -
Front End Shimmy Under Hard Braking?
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
So you're saying the shimmy is normal and I need to upgrade the shocks/springs and swaybar bushings to make it right? -
Get Cheap Valet And Wallet Keys For '02 Gs430
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
Sorry, I missed that. I've only seen master keys on ebay, no valet or wallet keys. -
Front End Shimmy Under Hard Braking?
Vette Boy posted a topic in 93 - 05 Lexus GS300 / GS400 / GS430
When I really step on my brakes the front end shimmys just a little bit, I can feel it through the steering wheel. Is it rotors, bushings or something else? -

What does the valve body mod do? -
Newbie Has A '02 Gs430, This Car Rocks!
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
Yer sick brother, get some help I modded up my SS big time. Then I went for an LT4 Vette 'cause it weighs 1000lbs less and has 100 extra HP. I'm keeping my GS stock....once I crack the factory set up and start "improving" the rattles and hassle start coming. I need a clean reliable business ride, the GS is as fast as my SS stock. -
80k Mile Service On An Gs430
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
An auto LT1 w/2.59 gear is a 14.2 sec car, that's 50% of all LT1 Vettes. With your mods you'll take 'em down in style. -
On the Vette forum, people brag about how low their mileage is, proof you're not a waxer His mileage seems about right, I doubt there's any different in mileage between the 6cyl/8cyl motors. With a modern computer controlled engine, mileage is more a function of the weight and aero charactistics (for a given driver). Of course, once you step on it, the bigger engine eats more air, so it needs more fuel. One reason to keep an eye on the mileage (whatever level it's at) is to make sure the O2 sensors are not getting "lazy". As the sensors start to fade, they don't react as quickley to throttle changes and poor mileage is the result. The driver can detect the sensors are going bad by noticing the gas mileage is dropping. Another symtom of fading O2 sensors is poor idle at stoplights, esp if the idle recovers in a few seconds. Unfortunatley, the weak link of any computer controlled engine is that there's no way to detect a fading O2 sensor. The freaking thing needs to be nearly dead before the SES light is set.

Installing Torque Converter
Vette Boy replied to Inrevinc's topic in 93 - 05 Lexus GS300 / GS400 / GS430
I'm new here, but I modded up an American V-8 sedan (96 Impala SS). The best mod I every made on it (and I made many!) was a shift kit and looser TC. I see the favorite TC of all the Vette/Camaro/F-bird/Imapala hot rodders is available for the GS430. The PI Vigalante is able to take over 600 ft*lbs of torque, that should cover the Supra Turbo 6 cylinder folks. - IMHO, my GS420 needs another ~1000 rpm stall speed. It takes too long to spool up the motor with the stock TC. - Even with the sport mode shift enabled, it's too long a shift time. - 0.5 seconds in the 1/4 mile seems a little high, I'd expect 0.2~0.3 seconds reduction, making the GS430 a 13 sec car...not too bad. - What do these valve body kits do? - I checked the TransGo site, they make the BEST kit for GM/Ford/Chrysler...nothing for the Lexus :cries: - I doubt you'll need a trans cooler with a looser TC, esp with a kit that shortens shift time (valve body kit?). Unless you go with an outragous stall speed (>3000rpm) the heat build up isn't much for a 2500-2800 rPM stall speed converter. -

I'm afraid to ask...what mods, any 1/4 mile times? -
80k Mile Service On An Gs430
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
For my LT4, 380/380 HP/torque isn't enough, that's why I'm installing long tubes, an 847 cam and porting the heads. 460HP/420FT*LBS should put me in the ~11.5 sec 1/4 mile and a 3.8 sec 0-60, that should take care of the new 911 Turbo -
80k Mile Service On An Gs430
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
I hear ya. I will always own a Vette, I love creaming all the posers in thier Eurotrash M3/5 and 911s. They always ask me how come they lost, R&T, Car & Driver says they should win (never assume a Vette is stock ) As for a daily driver, I can't take the GM interior anymore. I'm looking at the Lexus dealer where I bought my GS, they look pretty pricy too. Owning an Impala has taught me how to fix my own cars. The GS won't be any different. I'm not dropping $1,000 for the 90K service which includes about $150 worth of parts and fluids..... One thing I have noticed is it's lots easier to swap the plugs on a Lexus V8 compared to a GM V8 :) -
80k Mile Service On An Gs430
Vette Boy replied to Vette Boy's topic in 93 - 05 Lexus GS300 / GS400 / GS430
It's cranking fine, just takes a little long to start. I'm used to GM optispark, a piece of junk, but very fast starting, maybe I'm overreacting, The car is only 30 months old and has 70K miles, I figure everything is original. Here's what I was thinking for a 70K mile tune up: sparkplugs (denso iridiums?) O2 sensors (Stock denso; does the GS430 have 4 sensors or 2?) K&N air filter flush brakes (ATE super Blue) power steering (valvoline synth) trans (mobil 1 ATF) rear diff (mobil 1 GL5 75W-90) engine coolant (what kind?) fuel filter (Denso?) anything else? what do you think about the tune-up parts selection? -
80k Mile Service On An Gs430

Yes I do, I read it last night. I guess I'm going to swap all the fluids out and swap the plugs for starters. - Is there a factory service manual? - Any discount Lexus parts from internet sellers? -
Hello All, I just picked up an '02 GS430 with 70K miles. 30 months old, fully loaded with Nav, Mark Lev and 17" wheels. I replaced my 96 Impala SS with many mods, runs a 5.7 sec 0-60 and 14.2 sec quarter. I was tired of the old hag but I couldn't give up the performance...so I started looking at V8 sedans. Then this GS popped up, lots of miles in a short time period, just what I wanted. I also have a 96 Vette, LT4/6 speed with lots of mods and more coming. I plan on keeping the GS430 stock, I love the performace and luxury. It'll take me a few miles to learn to drive the speed limit. My Impala was a lot louder Eric

I just purchased a '02 GS430 with 70K miles on it. It's starting a little slow, I was wondering what was involved with an 80K service. What exactly does the dealer do @ 80K miles? Eric
