We've replaced and upgraded many SC430 stereo systems over the years. The best solution on the market currently is the Alpine INA-W900. The headunit is packed with all the features you need to make your SC sound great. Your main decision will be how extensive of an upgrade you are looking for. Some of our clients just opt to replace the blown speakers (if there are any) and just integrate the new DVD headunit into the factory system. Headunit installation should be handled by an experienced audio shop as a decent level of customization will be required. When we perform a headunit installation on the SC430 we make a custom kit/bezel for the new Alpine headunit to fit in the stock location. We maintain full operation of the motorized door during this process. Most importantly though is that the circuit board from the factory headunit is removed and maintained. If not, some vehicles lose total function of the navigation and climate control functions. An experienced shop should be able to install a new headunit for you and maintain operation of all interior electronics including the factory subwoofer. If you are looking for a total system upgrade then I suggest replacing all the speakers and factory amplifier with high quality components. Hope this helps a little.

TO SAVE ALL THE HASSLE AND HEADACHE I WOULD JUST CLAIM IT ON YOUR INSURANCE. YOU ARE NOT OBLIGATED TO LET HIM FIX YOUR VEHICLE. YOUR INSURANCE COMPANY WILL FIX YOUR VEHICLE PROPERLY AND THEY WILL SUE HIM OR HIS INSURANCE POLICY DIRECTLY. THE GUY IS ALREADY TRYING TO SAVE A FEW BUCKS BY FIXING IT HIMSELF. IF YOU'RE NOT CONFIDENT IN HIS ABILITIES I'D JUST FIND THE BEST BODY SHOP POSSIBLE AND TAKE IT FROM THERE. I WOULD ACT QUICKLY AS THE MORE TIME THAT PASSES THE MORE COMPLICATED THE SITUATION BECOMES AND PEOPLE MYSTERIOUSLY CATCH AMNESIA.

STOP WRITING IN ALL CAPS!!!!

LET ME EXPLAIN SOMETHING TO YOU SIR. I'M A GROAN MAN AND CAN TYPE IN ANY WAY I SO PLEASE. THE PEOPLE HERE IN THIS FORUM ARE ADULTS LOOKING FOR AND SHARING INFORMATION ABOUT THEIR VEHICLES. I THINK THE LEAST OF IMPORTANCE IS HOW SOMEONE CHOOSES TO TYPE. I UNDERSTAND THAT CHAT AND FORUM "ETIQUETTE" SAYS THAT ALL CAPS IS YELLING. GIVE IT A BREAK. IF YOU DO NOT LIKE WHAT SOMEONE TYPES THEN MOVE ON. THEIR ARE SO MANY MORE IMPORTANT THINGS TO WORRY ABOUT SIR.

I NEED HELP ,,,,MY CUSIUE CONTROL STOP WORKING THE LIGHT COMES ON BUT IT WONT WORK,,PLUS I DONT KNOW HOW FAST I'M GOING HELP ,,CLUSTER IS GOOD BUT THE SPEEDMONEDER WONT MOVE.

SOUNDS LIKE A SPEED SENSOR PROBLEM. I HAD THE SAME EXACT PROBLEM WITH AN ACURA LEGEND MANY YEARS AGO. THE SPEED SENSOR SENDS INFORMATION TO THE COMPUTER AND THE CRUISE CONTROL MODULE GATHERS SPEED SENSOR INFORMATION ALSO. I WOULD START THERE.

I have a 2002 SC430. I have P0155 (H02S) Heater Circuit Malfunction Bank 2 Sensor 1.

I need to know this location in the car and how to replace the Bank 2 Sensor 1.

The Lexus dealer gave me the price $150 just for diagnostic the problem. I think I could do it with your great instruction.

Please help

Thanks in advance

BANK TWO REFERENCES THE PASSENGER SIDE OF THE MOTOR. SENSOR ONE REFERENCES THE O2 SENSOR CLOSEST TO THE ENGINE. THIS IS NOT A VERY DIFFICULT PROCEDURE BUT WILL CERTAINLY REQUIRE THE VEHICLE TO BE LIFTED UP TO GAIN ACCESS. YOU WILL NEED A BASIC TOOL SET WITH SOME WRENCES. AFTER CHANGING THE SENSOR THE CHECK ENGINE LIGHT MAY REMAIN ON. YOUR LOCAL AUTO PARTS STORE SHOULD BE ABLE TO TURN THE LIGHT OFF FOR YOU.

I WOULD BUY THE SENSOR FROM THE DEALERSHIP. I'VE HAD TROUBLE WITH AFTERMARKET SENSORS BEFORE.

SEEMS TO ME THAT THE FACTORY ALARM ISN'T BEING DISENGAGED WHEN THE REMOTE START SYSTEM ACTIVATES THE IGNITION. THE UNLOCK/FACTORY ALARM DISARM WIRE IS AT THE THEFT ECU BEHIND THE GLOVE BOX OR PASSENGER KICK PANEL. IT IS YELLOW/BLUE AND NEGATIVE IN POLARITY. THERE SHOULD BE A WIRE FROM THE REMOTE START MODULE THAT SENDS GROUND TO THE UNLOCK/FACTORY ALARM DISARM WIRE TO DISARM THE FACTORY ALARM WHEN THE REMOTE START SYSTEM IS ENGAGED. YOUR WIRING WOULD HAVE TO BE INSPECTED BY A TECHNICIAN TO CONFIRM THIS.

I HAVE A 2002 SC430, WAS IN A ACCIDENT,,NOW THE ENGINE DOES NOT START ,, IT CRANKS BUT NO START..CANT SMELL ANY GAS,,WHAT SHOULD I CHECK,, AND THE ROOF STARTS FOR ABOUT 2 OR 3 SEC,THEN IT STOPS,,I HAVE TO TURN THE KEY OFF AFTER EVEY STOP TO COMPLETE THE OPEN OR CLOSE OPERATION

WHAT PART OF YOUR VEHICLE ENCOUNTERED THE COLLISION? WAS THE COLLISION MAJOR?SOUNDS LIKE MAYBE THE REAR SINCE THE TOP HAS BEEN AFFECTED. I'VE WORKED ON THESE VEHICLES AFTER REAR END COLLISIONS AND SEEN THEM WITH DAMAGE TO THE ARMS OF THE TOP MECHANISM. YOUR FIRST STEP WOULD BE TO CHECK FOR FUEL PRESSURE UP FRONT IN THE ENGINE COMPARTMENT. NEXT I WOULD CHECK TO SEE IF THE SPARK PLUGS AND INJECTORS ARE FIRING. YOU MIGHT WANT TO TAKE THE VEHICLE IN TO A SERVICE SHOP FOR A DIAGNOSTIC. SEVERAL SYSTEM MUST BE CHECKED WHICH WILL REQUIRE SOME DIAGNOSTIC TOOLS.

TRY WWW.TAPRECYCLING.COM ALSO. THEY SPECIALIZE IN TOYOTA/LEXUS VEHICLES.

I HAVE A 1993 SC400 AND I INSTALLED THE TAIL LAMPS FROM THE 1997+ SC400 IN MINE. NOW THE BLOWN BULB INDICATOR TURNS ON IN THE DASH. IS THERE A WAY TO PREVENT THIS FROM HAPPENING OR SHOULD I JUST DISASSEMBLE THE INSTRUMENT CLUSTER AND TAKE THE BULB OUT?

MY 2002 SC430 HAS THE FACTORY BRIDGESTONE POTENZA TIRES.  ANY UNEVEN ROAD SURFACE TRIES TO TURN THE TIRES.  DEALERSHIP TOLD ME THIS WAS A FRONT END ALIGNMENT PROBLEM.  BUT AFTER THE FRONT END WAS ALIGNED, THE PROBLEM IS ONLY SLIGHTLY BETTER.  IS THIS AN INHERENT PROBLEM WITH THE POTENZAS?  WHAT TIRE WILL PROVIDE THE BEST ROAD HANDLING PERFORMANCE SO I CAN ENJOY DRIVING MY FUN CAR?

I'VE BEEN USING NITTO NT555'S ON MY COUPE FOR MANY YEARS AND I LOVE THEM. GREAT FEEDBACK, DRY AND WET WEATHER TRACTION. I USE 245/40/18 ON FRONT AND 265/35/18 ON BACK.

THE TRANSMISSION COOLER IS INTEGRATED INTO THE BOTTOM OF THE RADIATOR.

IF GOING THE CUSTOM ROUTE, WHAT SIZE PIPING SHOULD BE USED AND WHAT REAR SECTION MUFFLERS WORK BEST?

WHAT ARE THE BEST OPTIONS FOR AN EXHAUST SYSTEM?

WHAT ARE MY OPTIONS FOR FRONT LOWER CONTROL ARM BUSHING REPLACEMENT. THEY WANT $550 EACH SIDE AT THE DEALER. IS THERE A BUSHING REPLACEMENT KIT OUT THERE. THANKS!!!

WIDE VARIETY OF CHOICES. THE EASIEST CHOICE WOULD BE TO FIND WHEELS IN 17X8.5 AND USE A 245/45/17 FRONT AND REAR. YOU COULD ALSO GO 17X10 IN THE REAR AND USE A 275/40/17.

THE FRONT BRAKES ON MY 93 SC400 MAKE A CLICKING SOUND ALSO WHENEVER I HIT THE BRAKES IN REVERSE. IT ALMOST SOUNDS LIKE SOMETHING IS LOOSE OR DISCONNECTED. I'VE CHECKED AND EVERYTHING LOOKS NORMAL.

:whistles:              No secret that the 2003 Z has had tire probs--Nissan was replacing them FOC to quell the uproar. Anyone with a 2003 sc430 tried to appeal to Lexus Corp for new/replacements for the early wear on these tires???  Any success??

the runflats on the SC430 only last 12k-15k miles, this is normal. When I went to the dealership they recommended non run flat Michelin Pilot AS tires. I've already put a set on a SC430 and it has made a world of difference. Better ride and last 3 times longer.

BETTER NOT GET A FLAT WHILE OUT OF CELL PHONE COVERAGE!

I HOOKED A CODE SCANNER UP TO MY 93 SC400 AND IT GIVE ME CODES 14 AND 41. DOES ANYONE KNOW WHAT THESE CODES ARE AND WHAT VEHICLE SYSTEMS THEY PERTAIN TO?

How much do you usually charge?

I USUALLY CHARGE $125 FOR A DOUBLE DIN INSTALL IN A LEXUS. MOST IMPORTANTLY, YOU SHOULD FIND SOMEONE IN YOUR AREA THAT KNOWS WHAT THEY ARE DOING. IT'S EITHER GOING TO LOOK GREAT OR IT GOING TO LOOK SCREWD UP.

I'VE JUST INSTALLED AN EIBACH PRO KIT ON MY SC400. LOOKS GREAT AND HANDLES GREAT BUT THE REAR SPRINGS MAKE A LOUD CLASHING SOUND WHENEVER I TRAVEL OVER BUMPS. I TALKED TO EIBACH AND THEY SAID THEY HAD ISSUES WITH THE SPRINGS ON THESE VEHICLES AND THAT THEY REVISED THEM. I HAD TO GIVE THEM THE SERIAL NUMBER OFF OF THE SPRINGS SO THEY CAN DETERMINE IF THE SPRINGS ARE THE OLD OR NEW DESIGN. THEY SAY THAT IF THEY ARE OF THE OLD DESIGN, THEY WILL SEND ME OUT ANOTHER SET OF SPRINGS. IF THEY ARE THE NES DESIGN THEY WILL SEND OUT SOME COIL ISOLATORS TO SLIDE OVER THE COILS TO DAMPEN THE SOUND WHEN COILS COMPRESS UNDER LOAD. HAS ANYONE ELSE EXPERIENCED THIS WITH LOWERING YOUR SC. I'LL REPOST WITH THE RESULTS FROM MY DEALINGS WITH EIBACH CUSTOMER SERVICE.

I USE AMSOIL SYNTHETIC GEAR OIL IN MY REAR END. THE OWNER'S MANUAL SAYS THE CAPACITY IS 1.5 QUARTS.

UNFORTUNATELY THERE IS NO MOUNTING KIT FOR OUR VEHICLE. I RECOMMEND TAKING IT TO A REPUTABLE STEREO SHOP IN YOUR AREA. I'VE INSTALLED COUNTLESS DOUBLE DIN UNITS IN LEXUS' AT MY SHOP.

I'VE READ THAT MY SC400 CAN BE LOWERED 2.5 INCHES BY INSTALLING TT SUPRA SPRINGS AND SHOCKS. WHAT CAMBER KITS ARE AVAILABLE FOR SUCH A DRAMATIC DROP?

I INSTALL THE K40 SYSTEM ON MANY HIGH END VEHICLES AT MY SHOP IN RICHMOND, VA INCLUDING MANY PLAYERS FOR THE WASHINGTON REDSKINS AND BALTIMORE RAVENS. I'VE DONE WORK FOR MICHAEL VICK ON SOME OF HIS VEHICLES AS WELL AND FROM MY REAL WORLD EXPERIENCE WITH THE CONSUMERS DIRECTLY, I'VE FOUND THE K40 TO BE THE MOST RELIABLE. I'VE OWNED AND TESTED EVERY TOP BRAND PERSONALLY.

235/50/16 WILL WORK GREAT!
