The 3.0-liter V6 Toyota 3GR-FSE engine was produced at the plant in Japan from 2003 to 2012 and was installed on such popular rear- and all-wheel drive models as the Crown and Mark X, as well as on the third generation Lexus GS300 sedans.
In 2003, a 3.0-liter V6 engine debuted on the new generation of the Crown model, which differed from its GR counterparts by the presence of a D-4 direct fuel injection system. And so this is a simple V-shaped six with an aluminum block and a 60 ° cylinder camber angle, a pair of DOHC cylinder heads with hydraulic compensators, a VVT-i phase regulator on four camshafts, an intake manifold equipped with an ACIS type variable geometry system, timing chain.
The restyled Mark X of the first generation was equipped with a compressor version of this engine. Thanks to the TX15 drive supercharger, this engine developed 320 hp and 412 Nm of torque.
The engine was installed on:
- Toyota Crown 12 (S180) in 2003 – 2008; Crown 13 (S200) in 2008 – 2012;
- Toyota Mark X 1 (X120) in 2004 – 2009;
- Lexus GS300 3 (S190) in 2005 – 2011.

Disadvantages of the 3GR-FSE engine
- The most famous problem with this engine is the appearance of scoring in the fifth cylinder. Two theories are put forward for their appearance: local overheating due to design defects or a gap in the air filter through which dust seeps into the combustion chambers.
- For power units, from 2006 to 2008, production carried out a recall campaign to replace defective valve springs: they could crack due to impurities in the metal.
- Engines of the GR series often pester owners with a crackling of phase regulators at startup. Sometimes it helps to replace only the sprockets, but many have to buy new couplings.
- Also on specialized forums they complain about the ever-leaking pump, short-lived ignition coils and delicate AFS mixture composition sensors and lambda probes, they cannot tolerate low-quality gasoline. On the engines of the first years, there is corrosion of the fuel pipes or leaks at the joints of the cylinder head.
