Turbo Parts, Intercoolers & Waste Gates

There are a lot of different techniques and technologies available to increase the performance of your four-wheel friend, and some of them come stock from the factory, so you need them to work at their best. One of those is the turbocharger, which is perhaps the most exciting part of the vehicle because it increases power by a big percentage at a very small cost to the engine.

We aim to provide our customers with the finest Turbochargers, Superchargers & Components the industry can offer, which is why we accept no compromise when it comes to the quality. Created by the most reputable names in the industry, such as Delphi, Genuine, Nissens, Victor Reinz, Valeo, AJUSA the Turbochargers, Superchargers & Components we've gathered for you feature precise design and everlasting durability.

The turbocharger uses the exhaust gases from the engine to spin a turbine, which is a set of fan blades very tightly packed together, which packs the air tightly. A compressor then shoves that air into the cylinders in the engine, which means the cylinders are getting more air than normal and are able to burn more fuel. When the turbo is boosting at a high PSI, the cylinders are getting a lot more air than normal.

There is only one type of turbocharger, but it has changed in the years since it was first designed. It uses two turbines, one to pack the air tightly, and the other, to squeeze as much of it as possible into the cylinder. There is a shaft connecting the two turbines, and this often uses a 'fluid bearing,' because of the massive amount of pressure and friction, which is a tightly packed layer of oil being pumped around the shaft. With the turbines spinning at up to 150,000 RPM, it is easy to see how quickly things can go wrong.

Some of the things that can go wrong include the shaft snapping, or one or more of the fan blades breaking. These often occur where the oil is not able to coat the shaft properly, which means the friction is a lot higher than it was designed to handle. Older turbochargers, using metal bearings, can snap those bearings or seize them solid because of the amount of work being done by it. If the waste gate fails, the exhaust gases may not be diverted properly or the compressed air may be leaking from the system.

When one or more of those problems occur, you will find serious symptoms showing themselves quickly. For instance, a large amount of smoke coming from the exhaust can be evidence that the turbocharger is leaking oil directly into the exhaust. If you notice the vehicle is losing boost, or is generally losing power, the turbocharger may not be running as efficiently as it is supposed to, and this is a sign of a serious problem. Oil leaks around the exhaust or the turbocharger are signs that it is on its way out, and if the vehicle begins running roughly, then the problem is serious.

This article will guide you through a generic tune up on most any car or light duty gasoline-powered vehicle built within the last 20 years or so. We will presume that you are tuning up your engine because it has reached the mileage or time point to do so, and that you are NOT performing a tune up to cure an engine performance defect. We make this distinction...
Internal combustion engines are extremely complex and feature a wide array of components that rotate, move up and down, pump, seal, or remain stationary. When repairing or rebuilding your engine, you will come across many different terms when referencing repair manuals and ordering parts. We know it can be confusing, especially when the repair is complex. Even if...

Product was great. Have not installed it yet, but should be no problem. Can't beat the price.
