ENGINE CHOICE 7M-GE 3.0L Cast-iron I-6 with Aluminum DOHC (9.1:1) 190-204hp @ 6000 Found in: * 1989-1992 Toyota Cressida MX83 * 1986-1992 Toyota Supra MA70 * 1988-1993 Toyota Soarer MZ20 The stock powerplant for the MX83 Cressida. Under heavy stress they usually suffer from head gasket failure(s) and occationally have rod failures due to extended abuse. The 7M is the 3.0L DOHC punched out last version of the Toyota M series engines that originated in the 60's with over 10 revisions throughout the decades. 7M-GTE 3.0L Turbocharged Cast-iron I-6 with Aluminum DOHC (8.4:1) 232hp @ 5600 Found in: * 1986.5-1992 Toyota Supra Turbo MA70 * 1988-1993 Toyota Soarer MZ20 The turbo version of the 7M-GE. Uses a single CT26. 1JZ-GTE 2.5L Twin-Turbocharged Cast-iron I-6 with Aluminum DOHC (8.5:1-9:1) 280hp @ 6200 Found in: * 1990-2003? Toyota Chaser, Mark II, Cresta, Verossa JZX81, JZX90, JZX100, JZX110 * 1990-1992 Toyota Supra 2.5GT JZA70 * 1991-1996 Toyota Soarer JZZ30 * 1999-2003 Toyota Crown JZS170 (Athlete V) Yamaha head design. Uses a parallel twin-turbo setup using two Toyota CT12a turbos. Coil-per-plug ignition, and a front mount intercooler. The engine mounts from the JZX81 will allow the 1JZ to bolt into an MX83. With the JZA70 1JZ and 5-speed R154 transmission, the shifter fits through the mx83 shifter location. The R154 transmission requires some work to fit to the mx83 (Hammering the doghouse sides and top to make room). 2JZ-GE 3.0L Cast-iron I-6 with Aluminum DOHC 215-230hp @ 5800-6000 found in: * Lexus IS 300 JCE10 * Lexus GS 300 JZS147, JZS161 * Lexus SC 300 JZZ30 * Toyota Aristo JZS147, JZS161 * Toyota Supra JZA80 Solid choice for a reliable but low power N/A build. Requires a lot of investment to bring the power up to the 300+ levels. Strong reliability, fairly low cost, and seemingly indestructibile durability make this engine a good choice to replace the 7M-GE. The Fly-by-wire VVT-i version in later cars might be harder to swap due to electronics. 2JZ-GTE 3.0L Twin-turbocharged Cast-iron I-6 with Aluminum DOHC 280-310hp @ 5600 Found in: * Toyota Aristo JZS147, JZS161 * Toyota Supra JZA80 The 3.0L version of the 1JZ. The Aristo version is equipped with the front sump oilpan that's required for a Cressida swap (the JZA80 Supra is mid-sump). JZX81 engine mounts also work with the 2JZ. 1.5JZ 3.0L Twin-turbocharged Cast-iron I-6 (2JZ) with Aluminum DOHC (1JZ) A hybrid version of the 1JZ and 2JZ where a 1JZ head is put onto a 2JZ. Usually to increase the displacement of a 1JZ setup. Not really different from a 2JZ-GTE other than the head manifold and some porting differences. Also, with the low cost of the 2JZ-GE shortblock and 1JZ-GTE engine sets, a 1.5JZ could be a cheaper alternative to a 2JZ-GTE in some places. 1UZ-FE 4.0L Aluminum V8 with Aluminum DOHC (10:1-10.5:1) 256-290hp @ 5600 Found in: * 1989-2000 Lexus LS 400 UCF10, UCF20 * 1989-2000 Toyota Celsior UCF10, UCF20 * 1990-2002 Toyota Crown UZS130, UZS140, UZS150, UZS170 * 1991-2000 Lexus SC 400 UZZ30 * 1991-2000 Toyota Soarer UZZ30 * 1992-2000 Lexus GS 400 UZS161 * 1992-2000 Toyota Aristo UZS161 The V8 that Toyota spent a reported $1B US on development to break into the luxury market in 1989, this ultra-overengineered all-aluminum DOHC engine has forged pistons and crank, 6-bolt main crank bearing caps (4 main bolts and 2 side bolts). Most 1UZ's also came with tubular header exhaust manifolds. The 1UZ is usually equipped with a number of catalytic converters and a very conservative factory ECU setting. The 1UZ benefits most from ECU tuning or replacement, and replacing the exhaust to allow a more tuned exhaust flow. The 1UZ has also been known to rev to 9000rpm with tuning. Dellow Automotive and some other companies make 5-speed conversion parts for the 1UZ to adapt Toyota R and W transmissions. An X83 Cressida with a 1UZ would be the best N/A setup for the investment since 1UZ motors are relatively inexpensive. After 2000 the 1UZ was replaced by the 4.3L Version with slightly increased torque called the 3UZ-FE.

NISSAN SR20DET 2.0L Cast-iron I-4 with Aluminum DOHC This swap has been done in a Cressida in the US (Vids). and works out really nice. NISSAN RB 2.0L-2.6L Turbocharged Cast-iron I-6 with Aluminum DOHC RB motors have been put into JZX81 and GX81 models. OTHERS 3S-GTE 2.0L Cast-iron I-4 with Aluminum DOHC 185-256hp @ 6200 A decent 4 cylinder found in the ST215, ST246 Toyota Caldina (Japan), SW20 MR2 turbo, ST185, ST195, and ST205 Celica GT-FOUR, and the Toyota Altezza SXE10 (non-turbo) that could be adapted to a Cressida. The Altezza BEAMS/YAMAHA 3S-GE has the proper front oil sump location and the AZ6 rwd manual transmission should fit well into the stock shifter location. Engine mounts from a JDM SX81 Mark II would probably work, switching to low compression pistons and adding a turbo setup to create a 3SGTE would probably work out pretty well too. Not cheap, but would work. The Aisin AZ6 gearbox is the same one used in the 99-05 6MT Miata, 6MT RX8 and S15 Silvia. driveshaftshop.com might be able to make a driveshaft for this setup too. LS1 5.7L Aluminum V8 with Aluminum pushrod design Found in: * 1997-2004 Chevrolet Corvette C5, excluding Z06 * 1998-2002 Chevrolet Camaro Z28, Z28 SS * 1998-2002 Pontiac Firebird Formula and Trans-Am * 2004 Pontiac GTO GM's new aluminum block 350 would fit, but yet to have been done in a Cressida. The cast iron 350's could be used too, but since the LS1 would represent the lighter more advanced choice, there are better (easier) options. 13B (RE, REW, 20B) Turbocharged Rotary Found in: * Mazda RX7 and Cosmo Because of its light weight, compact size and tuning potential stemming from is inherent high power to weight ratio the 13B could be put to use in a Cressida. 1GZ-FE 5.0L 48 valve DOHC V12 280hp @ 5200 Found in: * 1997-present Toyota Century Do it people.
