Differences between the SC300 & SC400
The SC300 comes with a 3.0-liter 182 ci cast iron inline-6 motor with aluminum heads (engine designation: 2JZ-GE) and a choice between a Toyota A343E 4-speed automatic transmission with overdrive or a Toyota W58 5-speed manual transmission (available from 1992-1997).
From 1992-1997, the power was rated as 225 horsepower @ 6000 rpm and 210 ft/lb torque @ 4800 rpm. From 1998-2000, the power was rated as 225 horsepower @ 6000 rpm and 220 ft/lb torque @ 4000 rpm. Curb weight ranges from 3494 lbs. in 1992 to 3560 lbs. in 2000.
The SC400 comes with a 4.0-liter 242 ci cast aluminum V-8 motor with aluminum heads (engine designation: 1UZ-FE) and a standard equipped Toyota A343E 4-speed automatic transmission with overdrive (from 1992-1997). No manual transmission was ever offered for the SC400.
From 1992-1995, the power was rated as 250 horsepower @ 5600 rpm and 260 ft/lb torque @ 4400 rpm. From 1996-1997, the power was rated as 260 horsepower @ 5600 rpm and 270 ft/lb torque @ 4400 rpm. From 1998-2000, the power was rated as 290 horsepower @ 6000 rpm and 300 ft/lb torque @ 4000 rpm. Curb weight ranges from 3575 lbs. in 1992 to 3655 lbs. in 2000.
Manual transmissions were never offered for the SC400 and were discontinued after 1997 on the SC300. The SC300s that came with optional Toyota W58 5-speed manual transmissions do not come equipped with traction control.
In 1998 the SC400 received a Toyota A650E 5-speed automatic transmission with advanced ECT-i and a burl-wood gated shifter (from 1998-2000), while the 1998 SC300 received a Toyota A343E 4-speed automatic transmission with burl-wood gated shifter (from 1998-2000).
In 1998, both the SC300 and SC400 received VVT-i (intelligent variable valve timing) engine technology. These motors have completely redesigned heads, which boast variable valve timing on their intake camshafts via an oil-driven helical gear-drive. 1998 and newer Lexus models with 4.0L V-8s are capable of low to high 14-second quarter miles. - (info provided by gs400998)
The SC400 came stock with 16x7.5-inch alloy wheels and the SC300 came stock with 15x6.5-inch turbine-cut alloy wheels.
The SC400 came with power automated telescoping/tilting steering wheel, and the third brake light was mounted inside the spoiler as opposed to on the rear dash behind the windshield in the SC300. The SC400 has larger disc brakes (11.7-inch front & 12.1-inch rear) compared to the SC300 (10.8-inch front & 11.4-inch rear). The SC300 had an optional but very rare velour (gray or tan) interior and optional but very rare hard top (no moonroof).
There are no substantial body differences between the SC300 and SC400. Models that did not include a spoiler with LED-third brake light, standard on the SC400 and optional on the SC300, were fitted with a third brake light on the rear deck behind the rear windshield.

Production year revisions in the SC300
Info Provided by Rich @ http://www.intellexual.net/faq.html#001
Production year revisions in the SC300
The rear shifting assembly on the SC300 was changed in 1995 and is the same as the Supra NA (as far as I know '93-98), but it is unknown if the '93-94 Supra NA uses the same transmission because the TRD quick shift kit is designed for '94.1 and later. The transmission change went along with the changes that were made to the transmission tunnel. The 1995 transmission is longer and taller so you can cut the existing hole where the shifter goes through but you will have to hammer part of the tunnel to make it taller. Basically the '92-94 SC300s have the same W58 manual transmission, but then the '95-97 have an updated version. Original info: provided by SDSC300
