These have four O2's. Two before the cats and two behind. That would be four wires then. I dunno.

TAP is in Cali also.

You ought to try TAP recycling. They part out salvaged SC's. 1-800-765-7100.

Thanks for the info guys. I may just try out those Tokico blues. Do you all think these are just as good as Koni? Are the Tokicos good for life like the Konis? Thanks.

I was looking into putting a set of Koni shocks on my SC400, but found that they dont make a set for the SC's. I called Koni and they verified this. However, the Koni guy did say that someone had told him that the Supra Konis were interchangable with the SC400. He was just not positive. Has anyone here tried the Supra Konis on an SC? Also what are considered the best shocks for the SC400? Thx.

I havent lowered it. I do have the '95 rims on it. I believe they are the same size though.

I'm experiencing heavy wear to the inside on my tires, front and back. The car tracks perfect though. I take my hands off the wheel and it goes straight as could be. The tire guys tell me that my alignment is off. Have any of you all experienced this problem. Is this some sort of a performance inhancement for increased handeling? I've noticed Porsche 911's rear wheels with this negative camber as I believe it's called. I also only got 14k off these Dunlop S5000's. Does the SC typically burn through tires this fast? Thanks.

A good place for used lexus parts is www.taprecycling.com out of CA. They buy wrecked Lexus and Toyotas then part them out.

Oh well, When I think of long engine life I'm thinking of 250-300k. You have apparently blown that out of the water. Thats really good to hear. So apparently your friend has had no problems with non-synthetics breaking down and leaving any residue sludge in the motor? I really have no experience with owning high mileage vehicles. This 93' SC400 would be the highest I've ever had at 123k. It sounds like your getting along fine and should probably ignore my posting. I just thought that it sounded like some really killer stuff and was coming from mutiple sources, who I felt to be credible, with nothing to personally gain from their recomendation. Do you happen to know how long one can expect to have an SC400 engine last with proper maintenance? Thanks

Hello...1993 SC400 here, I would recommend everyone look into switching to a high grade synthetic oil for any age vehicle regardless of what the dealer might say. I've recently met up with various serious racing and high performance insiders. When I've had the opportunity to pick their brains one product keeps creeping into the conversation. Amsoil. They have especially been impressed with the Series 2000 line 0w30. This is supposedly some really killer sh@t. In the area of wear protection and longevity nothing even comes close. I've had a friend run it in his 94 SC400 for the last year. Amsoil recommends a change interval of 35,000 mi or one year with filter changes at 12k. Although one guy I talked to sent a sample of his batch into the Amsoil lab for analysis after 50k and the results reported no degeneration detected. Also these lab tests are supposed to give you an idea of the condition of your motor. I mentioned Mobil 1 to these guys and they just laugh. I always thought Mobile 1 to be one of the best. Apparently there is no comparison according to the people who are in the know. These people had nothing to gain by teling me about this product as they werent dealers and several of the guys I talked to didnt even know each other yet had the same advice. I went ahead and put Amsoil diffential, transmission and motor oil 0w30 in last week. It ran about $145.00 for the products alone, but from what I've heard this is probably worth while. You may want to look into these synthetics for yourself. I believe in them. The dealer and other mechanics arent neccessarily concerned with your car's longevity. Look at the marine industry. I dont think anybody still uses non-synthetic anymore and marine motors really get put through the ringer. Also, stay away from any of these oil additives!! BAD NEWS!! ..No SLICK 50!!... No Dura LUBE!! The teflon does not get hot enough to bond to moving parts and they end up clogging your filters and oil pick-up!!!! STAY AWAY!!! That news is probably well know by now though. And with Duralube its like a chroline bleachy substance that gives temporary friction reduction but then with the heat converts into some caustic material that proceeds to eat up your motor. Well gotta go. Hope I helped.
