They do make Torque Converter for the SC300. Its runs about $900. I'm not sure how they work exactly, but from talking to people that have them they are great upgrades. Biggest bang for the buck (besides turbo).

Yes, scpower, a converter is available for the SC3. What a torque converter does is multiply the torque of the engine through hydraulic principles. Stall is the speed to which the engine turns while holding the brakes, before the tyres start to spin, it's the speed at which the converter 'locks' and applies all available engine torque to the input shaft of the transmission. Flash stall is the rpm the engine will reach before the car moves, when you're just taking your foot off the brake and nailing the gas from a stop. Several things can affect the stall speed a converter actually gives you, but the biggest factor is engine torque. More torque, with all other things being equal, will result in more 'stall,' the converter will flash at a higher rpm. A converter can be reworked by playing with stator angles and so forth, to give you more or less stall, but we won't get into how to rework a converter. There are no drawbacks, the 0-60 time on these cars improves dramatically with a nice converter, you'll wish you had installed one sooner. The best out there is the Precision Industries 'Dragon' unit, it is 9.5" (smaller generally equals more stall) and is a completely new casting with anti-baloon plate and the like. Cost is prohibitive, it's a bit under a grand, but it's not a reworked stock core like everyone else's, and if you're in manufacturing, you will understand why it costs so much to develop a completely new unit. You can contact Precision directly at converter.com, or you can buy one from SRT. Installation from Lexus will border on $500, i'm sure you can get a competent local shop to do it for less if you want. One alternative I can provide for you is a local guy here that I know that'll build a reworked core to stall at about 2700-2800rpm for about $300 bucks (no that's not a typo). This is the gentleman that builds the converters for the Performance Factory NYC's low 8-sec Supra.

Lex luthor ,

Thanks for also answering my question.

I was just curious what is the factory stall on a SC300. I was playing with the car the other day and I can get the car to about 2100 RPM with no tire spin or anything while in drive.

Would a stall of 2800 RPM be that much different and help me that much more?

How long does your friend in NY take to re-build/ship the converter back?
