A twin turbo source for SC400
http://www.mechtech-ms.com/html/turbo.html
Here is a blurb grabbed from above link:
MECHTECH TWIN-TURBO SC400
Adding a performance heart to a lavish Luxo-Cruiser
TEXT & PHOTOS BY LAWSON MOLLICA
Back in 1993, a leading consumer magazine rated the Lexus SC400 one of the best cars ever-at any price. The only reported drawbacks were its lack of overall power and its somewhat sparse rear-seating capacity. For Bill Craig, owner of this sleeper '94 Lexus SC400, these drawbacks really didn't matter. "I didn't care about rear seat room," says Bill, "and it has been my goal since purchasing the vehicle to turbo or supercharge it to get the performance." When the time came, Bill contacted TRD USA and the local Lexus dealership and both suggested that he look into quenching his thirst for power with a twin-turbo set-up that was being developed by MechTech in Escondido, California. Having received such high recommendations, Bill made a call to MechTech owner Jim McFarland and the rest, as they say, is history.

Not worth it...... I would suggest that if you REAAALLLYYY want to run HIGH HP ...... get a 300.
I was looking at one the other day and al,most pulled the trigger on the deal...but I thought I'd think about it over the weekend
2 SC coupes at one house (girlfriend)may not help the relationship... lol

Custom? $$$$$
Trying to get power from an SC400 is hopeless. Opening up my '93 has improved it I think to about it's limit, my 1/4 miles tell me the car's making about 225-235 at the tires. Forced induction is the only place to go from here, and like the old Powerglides (powerslip is their nickname) luxury and performance don't mix when it comes to automatic transmissions. Yeah I could run NOS, but I'd have to have a tank the size of the trunk to match my driving habits
God, I wish Toyota would build the Supra again.

Mad Max,
What are your mods to get 230-235 at the wheels. I have measured about 195-200 rwhp with a gtech. I only have a custom exhaust with rear cat removed and true duals from the convertors back. Still have the stock mufflers. I am thinking of removing the front cats and adding some dynomax ultraflo's. Do you think it would help??

its not that simple... but 800hp isn't the limit for the car... plenty making more than that around the USA... and the j-spec motor is about the same as the US-spec
This brings me to my point, just BUY an SC300 with a 5-speed and if you can't find a 5-speed get one with an auto for a good deal if you can find it; this is all if you intend to make the car go fast...
95rwhp extra from a twinturbo mod? LOL then it will be ALMOST able to hang with a $22k Z28

Mechtech
I called Mechtech about their so called turbo kit. They told me it wasnt available as a kit and that they only did that one car. And if I wanted it done I would have to send my car to them and pay about 15K. For 250 - 300 whp?@#$@ No way! Not worth it at all.
As far as how string the SC400 motor is, not many people have tried to take the motor to the limits in stock form. So its hard to say. But I have read and heard people say that it can handle 500 - 800 hp. Transmission is another story. Heres a modifier that is doing some cool things with the SC400. Check it it out : http://powerhousecorp.net/lexus.htm

The car's sound is interesting.. I left everything stock in the exhaust system except for the weak points, I replaced the mufflers with magnaflows and instead of running a true dual I put in a crossover. I also use a weapon-r shielded cold air intake with their V2 air filter. I'm using the equation, weight of car + driver and the trap speed, but it would be fun to see what one of those performance meters says.
