The best way to find a Mitsubishi engine is through a person who has one that has been wrecked. If you are lucky you can locate a car that was involved in a rear end collision that will not effect the motor in anyway. Search the papers in your area to find wrecked Mitsubishi cars and start calling the numbers. You will find that most of them are just for parts as they have been involved in front end collisions or the motor has been blown in one way or another. Non-modified motors are hard to come by as well as most will immediately modify the engine to bring it to peak performance. One of the most common modifications is new heads that have larger ports for injection. This increases the overall performance of the engine as it relates to the amount of fuel it needs to attain top speed. You will also find that most of the time the injection systems have been changed, this works to increase power as the flow of fuel from the tank to the engine is increase three or four times over. The problem is, if someone wants the engine for a regular car then they need to undo what modifications have been done. This is because some of them are not street legal and also they decrease the fuel efficiency way to far to be affordable for everyday driving. The normal Mitsubishi engine is affordable because it is power and fuel-efficient at the same time. If you are lucky enough to find an engine that has received no modifications then you have a jewel that is very valuable. The best course of action is to sell the motor if it does not fit your needs. You will get enough money from the sale to purchase two non-modified motors.
Internet auction sites are the newest tool in the search for the Mitsubishi engine. There has been a definite increase in the number of engines that have listed at these sites and the prices tend to run high. They work as a good tool because not only can you purchase the engine but also the necessary parts to make it what you want. There are more than enough parts dealers on the web to make this become a reality.
