The Mitsubishi 4G63T engine came in three generations. The first generation came from 1987 to 1996 and powered many Mitsubishi production and racing cars, from the Galant VR-4, Lancer EX 2000 Turbo, and Lancer EVO I to III.
The second-gen 4G63T entered the scene from 1996 to 2001, and powered the Lancer Evo IV, V, and VI to rally dominance. Swedish rally driver Tommi Mäkinen won consecutive WRC championships from 1996 to 1999, culminating in the rare Lancer Evolution 6.5 TME (Tomi Mäkinen Edition). The third-generation 4G63T came from 2001 to 2007 and powered the Lancer Evo VII, VIII, and IX. The Mk3 4G63T is unique for its MIVEC-equipped valvetrain.
All three generations of the 4G63T share a bore and stroke of 85 mm x 88 mm, and have an aluminum cylinder head and a cast-iron cylinder block with oil jets to cool the pistons. The sturdy engine block has cast aluminum pistons, a forged steel crankshaft, and forged connecting rods, enabling the 4G63T to handle more power than stock.
Proof of the 4G63T engine’s potency is the Evo VIII FQ-400, a UK-bound special that is as rare as it is quick. Tuned by Mitsubishi Ralliart UK, only 100 FQ-400s left the factory: Each has a heavily reworked 4G63T with 405 horsepower, enough to push it from 0-60 mph in 3.5 seconds. The robust construction and astronomical tuning potential have made the Mitsubishi 4G63T a byword in the racing and tuning community.
