Ok people it's time for an ICONIC ENGINES video of Mitsubishi's glorious 4G63! The 4G63 is such a great design that people didn't get sick of it was the Mitsubishi Lancer Evolution for 9 generations. When the Lancer X got a brand new, more modern engine, everybody was totally dissapointed. They still wanted the 4G63. They didn't get sick of it after 9 generations.

But if your think that the 4G63 started it's life with the Lancer EVO you are wrong! The first car that had a 4G63 in it was a Mitsubishi Lancer, but it wasn't an evo. The first car that had a genuine 2 liter turbo 4G63 in it was the Mitsubishi Lancer EX 2000 turbo from 1981. This thing was SOHC but still a genuine 4G63 that kicked ass even back in the early 80s. It made more power than it's competitors (lancer ex 2000 turbo - 170hp, bmw 323i - 143hp) and already had a lot of the evo recipe in it. It wasn't AWD but it was a boring looking four door sedan that would kick sports car butt.

Later on the 4G63 both in turbo and naturally aspirated form would appear in a real laundry list of different cars and it's still being manufactured today. So, how much HP does a 4g63 have? Well, as you can see this thing has been in production for more almost 39 years (yet it's still being installed in some Chinese vesicles today, although these are of questionable design) so there have been many different versions and revision of the 4g63. The 4g63 in factory form it makes anywhere from 170 to 400+ horsepower hp. The 400+ hp figure belongs to the Ralliart FQ400 special edition Lancer evos. But 250-300 hp is the usual factory figure for a modern 4G63.

So what about the specs? The specs are what makes any engine great and the 4g63 has all the right ones for making power. A cast iron block with closed deck design ensures the 4g63 can take all the boost you can come up with. Beefy internals? Check! Forged steel fully counterweight crankshaft? Check! Good cylinder head design? Check! The 4g63 has it all. Another interesting feature of the 4g63 is that Mitsubishi didn't just want to impress people with the power, it wanted to the impress people with how smooth and quiet the 4g63 is at idle and how it doesn't transmit the noise vibration and harshness that a typical 4 cylinder does. So inside the block of the 4g63 we can find some balancing shafts and in the cylinder head some hydraulic valve lifters. Both of these are ok for street applications but for high horsepower builds both will likely need to go away.

The 4g63 engine has been around for a very long time so many amazing builds have appeared over the years. Since its plentiful and popular it also means that the 4G63 has an amazing aftermarket and you can build an amazing engine. 4g63 stock internals are safe and reliable up to about 400 hp and a bit more if you do your tuning right. People even build up the stock internals and turbo to 500hp but I'm pretty sure reliability and driveability starts falling off right around 500 hp. Beyond 500 hp on a 4g63 you are likely looking at forged rods and pistons, camshafts, cam gears, turbo manifolds, forged internals, and a lot more. The stock crank can stay even at 700-800hp.

Another useful thing Mitsubishi owners or anyone building a 4g63 (swap perhaps?) can make use of is the 4G64 engine. It's basically a 2.4 version of the 4g6 family of engines. The 4g64 is super plentiful and widely available and is an easy and cheap way to get more torque and increase the displacement of your 4g63/ 4g64 build.

All in all the 4g63 is definitely deserving of the ICONIC engine status! It's well made, reliable, well-designed, has a rich racing history, it's capable, has amazing torque and on top of that it has a great aftermarket and astounding power potential!
