One unique thing about this club is that expertise (and love not to forget) of Racer bro's with this car 
4G63
The 4G63 was a 1997 cc version. There were two different bore and stroke versions, SOHC and DOHC were produced. The DOHC version came turbocharged or naturally aspirated. It is found in various Mitsubishi models including the 1990-1999 Eclipse and Galant.
The Mitsubishi Eclipse, Eagle Talon and Plymouth Laser introduced the DOHC turbocharged version to the U.S. through the Diamond Star Motors joint venture between Mitsubishi Motors and the Chrysler Corporation (now DaimlerChrysler). 1990 to late April 1992 came with beefier rods and used 6 bolts to secure the flywheel to the crankshaft, May 1992 to present EVO versions have lighter rods and use 7 bolts to secure the flywheel to the crankshaft. They are referred to as the "six bolt" and "seven bolt" engines, respectively.
Output for the US-spec 2004 Mitsubishi Lancer Evolution is 271 hp (202 kW) at 6500 rpm with 273 ft¡lbf (370 N¡m) of torque at 3500 rpm. It has a cast iron engine block and aluminum DOHC cylinder head. It uses MPI multi-point fuel injection, has 4 valves per cylinder, is turbocharged and intercooled and features forged steel connecting rods. With the release of the Lancer Evolution IX (286hp @ 6500rpm, 289ft*lb of @ 3500rpm, 7000rpm redline), it has received Mitsubishi's MIVEC variable valve timing system, which gives smoother power delivery and a flatter torque curve.
In the United Kingdom, a special Lancer Evolution, the FQ-400, produces 302.13 kW (405.2 hp), from a 4G63 engine. At 202.9 hp (151.3 kW) per liter, it has possibly the highest specific output per liter of any production engine.
Racing
Its turbocharged variant, 4G63T (also sometimes referred to simply as the 4G63), has powered Mitsubishi vehicles in World Rally Championships for years in the Mitsubishi Galant VR-4, Lancer Evolution, Carisma GT and Lancer WRC04. It was the powerplant of the Lancer Evolution when Tommi Mäkinen won his four sequential WRC championships. The engine is also used in a variety of turbocharged 2-liter models of Galant and Eclipse.
