The 4G64 is an extended version of the 4G63 engine. Its features include 750cc fuel injectors, a 3-inch exhaust system, and an EVO turbocharger. The car’s engine is mostly used in Chinese cars and is known to be prone to rough idle and vibrations.
Needs 750cc fuel injectors
When the fuel injectors in your car begin to fail, you’ll need to replace them. This procedure requires a lot of time, patience, and gas. Choosing the right injectors for your car is an essential first step. Make sure the ones you buy will fit the engine and your vehicle.
If you’d like to improve your 4G64’s power, consider upgrading to 750cc fuel injectors. These injectors will produce more power and have a faster spool than the stock injectors. This modification will require a new fuel pump, ECU, and exhaust system. You’ll need a 3-inch exhaust system for the 750cc injectors, and the engine will need a 255 lph fuel pump.
The Mitsubishi 4G64 engine is a member of the Sirius family of engines. It was first introduced in 1989 for the Fifth Generation Mitsubishi Galant. It is made by SAME in Shenyang, China, and is assembled through semi-knockdown kits. The 4G64’s torque peak occurs at 3,500 rpm, and it has class-leading fuel economy.
Needs 3-inch exhaust system
The Mitsubishi 4G64 engine is a four-cylinder engine that is a part of the Sirius Family. This engine first debuted in 1989 on the Fifth Generation Mitsubishi Galant. It is a quarter-liter inline-four engine that is made in Shenyang, China. The first engines were assembled by Shenyang Aerospace Mitsubishi Motors Engine Manufacturing in 1998, and regular assembly was not completed until April 2000. The 4G64 engine is still manufactured and primarily sold for the Chinese market.
The engine is similar to the 4G63 but has a smaller displacement. The 4G64’s head is a DOHC with a modern 16-valve head. It has a 9:1 compression ratio, and it can produce 156 horsepower at 6,000 rpm. This engine requires a 2.5-inch exhaust system and a 4-2-1 header. It also has forged internals and can be configured to produce up to 200 HP.
Needs EVO turbocharger
The 4G64 engine can be upgraded with an EVO turbocharger by replacing the stock head with an EVO one. The EVO head comes with a 3” exhaust system and can increase horsepower by 300 to 400 HP. The EVO turbo also comes with a larger radiator and requires a custom ECU configuration. The 4G64 engine with EVO head is equipped with forged pistons and 150-mm connecting rods. The car also requires EVO spark plugs, ignition coils, and headers.
The Mitsubishi EVO lacks mid-range torque, and this can be a problem for daily drivers. Thankfully, there are plenty of options for increasing the displacement of the engine. Adding a 100mm 4G64 crankshaft and 4G64 blocks are some of the options that can increase displacement.
Needs LPG version
The 4G64 is a gasoline-powered engine with an 8-valve SOHC head. The displacement is 275cc, and the four cylinders are linked in a V-shaped fashion. The four-cylinder engine develops 115 hp at 5,000 rpm. The engine uses a belt drive for timing. A replacement belt is required every 60,000 miles. The 4G64 is part of the Sirius family, which also includes the 4G63, 4G61, and 4G62 engines. The 4G64 GDI is a variant with a 16-valve SOHC head and direct injection. It is found in the Mitsubishi Canter and is available in a petrol-powered version.
The 4G64 engine was first developed by the Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co. in 1983, and is still in production today. This engine is available in both the petrol and LPG versions. It is the best option for cars with eight and 16-valves. It is also used in forklifts. Its LPG version was released in March 1996.
