Identifying the Correct Turbo
The best way to identify the correct turbo for your car is to take a look at the turbochargers name plate on the unit itself, engraved on the plate will be the turbo model name, turbo manufacturer's part number and the vehicles manufacturer's part number of which you can match up when searching for a replacement.
If the name plate is missing or difficult to read on the turbocharger, please obtain the following information to help us determine the correct turbocharger for your application using our vehicle parts database and email us over your:

Symptoms of a Turbocharger Failure:
The easiest way to diagnose a weak turbo is to observe the vacuum/boost gauge or boost indicator light. If at full throttle it doesn't show full boost (typically 9 to 14 PSI for many OEM turbo systems) it's best to have it looked at by a professional mechanic. However be warned, as excessive backpressure (often due to a clogged catalytic converter) can also prevent the turbo from developing its normal boost pressure.
What is a VGT or VNT Turbo?
Variable-geometry turbochargers (VGTs) are a family of turbochargers, usually designed to allow the effective aspect ratio (sometimes called A/R Ratio) of the turbo to be altered as conditions change. This is done because optimum aspect ratio at low engine speeds is very different from that at high engine speeds. If the aspect ratio is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust manifold pressures, high pumping losses, and ultimately lower power output. By altering the geometry of the turbine housing as the engine accelerates, the turbo's aspect ratio can be maintained at its optimum. Because of this, VGTs have a minimal amount of lag, have a low boost threshold, and are very efficient at higher engine speeds. VGTs do not require a wastegate. VGTs tend to be much more common on diesel engines as the lower exhaust temperatures mean they are less prone to failure. The few early gasoline-engine VGTs required significant pre-charge cooling to extend the turbocharger life to reasonable levels, but advances in material technology has improved their resistance to the high temperatures of gasoline engine exhaust and they have started to appear increasingly in, e.g., gasoline-engined sports cars.
WARNING - THE EXPENSIVE TRUTH ABOUT CHEAP TURBO'S!
Please be VERY aware of non original turbochargers on the market.
The first instance is to think 'I'll get that one because it's the cheapest', however most are actually counterfeit Chinese pattern part turbo's. Companies that sell this type of turbo will often have no PRODUCT LIABILITY INSURANCE because an insurance company will only give product liability insurance to a company for the manufacture of a serious engine component if they have a comprehensive quality control program.
Cheap counterfeit turbochargers will fail prematurely and can easily cause serious engine damage as they break up.
Many counterfeit Chinese made turbo's appearing on the market have undergone thorough testing side by side with genuine units by experts such as Cummins Inc. and have been proven that they do NOT meet safety standards when tested to destruction because of the low quality materials used during manufacture.
Genuine Turbo's have to pass stringent tests to make sure that in the event of a failure, the internals are kept within the housing, counterfeit turbo's have been found to EXPLODE off the testing bench under the same operating pressure.They have no where near the same depth of precision and quality as an original unit! So if you want to look after your car and your pocket in the long run, buy an original manufactured turbo!
