Remanufactured
Remanufactured engines are engines that have been damaged, they are sent to machine shops to be remanufactured to the manufacturers specifications. Jasper Engines defines this as to make the engine as close to new as possible. These engines are stronger and more durable than those that come from the factory. Remanufactured engines are often known as Reman engines. There are both positives and negatives to engine remanufacturing. Remanufactured engines are cheaper than rebuilt engines, and the remanufacturer is able to provide a warranty. Allowing the customer to have piece of mind knowing that the company that remanufactured their engine is able to stand behind their work. However, the customer should always remember that the remanufactured engine is not a new engine, meaning that the engine is still susceptable to future breakdowns, wear, and repair.

Chip Tuning
Most modern engines have an Engine Control Unit (ECU), which enables performance enthusiasts to tune your car to be able to run at a greater performance level. These computers are able to be reprogrammed to allow tuning of the engine to run smoothly, efficiently and add an increase of performance. There are many manufacturers that produce these chip tuners, allowing the customer to choose which tuner works best for their car. However, most plug-and-play chips are designed and engineered to be used in stock vehicles. If your vehicle is already modified, additional tuning may be suggested to ensure that the tune is safe for your car. Tuners allow the driver to monitor engine performance, such as 0-60 time, engine RPM, oil temperature, coolant temperature, fuel pressure and more. They can monitor any engine component or accessory that has a sensor reading back to the ECU.

Forced Induction[edit]
Forced Induction happens when an engine has a much greater amount of air being forced into the intake, thus building horsepower. There are two common ways of using forced induction: turbochargers and superchargers. Turbochargers and superchargers are basically air compressors designed to shove more air into the engine. Turbochargers are driven off of the engine's exhaust, the exhaust flow causes the turbine to spin. The turbine compresses the air and pushes this air to the engine, causing a greater amount of air to enter the combustion chamber of the engine. Superchargers are similar but different; superchargers are mounted directly to the engine's intake manifold. Superchargers are driven by a belt or chain running off of the engine's crankshaft. Evidence has shown that superchargers increase horsepower by up to 46 percent, with an increase of up to 31 percent more torque. Superchargers have varying designs, but turbochargers are relatively the same. Some of the common supercharger designs are Roots, Twin Screw, and Centrifugal. Roots and Twin-Screw superchargers provide more horsepower at lower RPMs, whereas centrifugal superchargers increase horsepower at a higher RPM. The advantages of a supercharger are that you can add one to any vehicle, this allows you to increase horsepower on any vehicle that the supercharger fits. Superchargers are just as efficient as turbochargers, but superchargers create instant power, whereas the turbocharger suffers from turbo lag. Turbo lag happens when there is not enough exhaust flow to cause the turbine to build pressure, no pressure means no horsepower gains.

Engine Tune-up[edit]
When performing an engine tune up, there are many ways of increasing the performance, efficiency, reliability, and overall strength of an engine. Some basic ways of increasing the reliability of an engine is to regularly change the air filters, fuel and oil filters, battery, alternator, and many other accessories. Spark plugs are also important to check on, spark plugs are the key to allowing gasoline engines to run. The spark causes an explosion in the combustion chamber, the explosion pushes the piston down causing the crankshaft to spin. The crankshaft transmits power to the transmission, allowing power to flow to the wheels. Timing adjustments are beneficial because timing allows the engine to run smoothly without the components having excessive wear. All of these maintenance suggestions are helpful when a customer wants their engine to run efficiently and smoothly for as long as possible.
