We will repair or replace any part or turbo that we provided (original purchaser only) that is found to be defective due to failure of material or workmanship for a period of twelve months from date of invoice. This WARRANTY IS LIMITED to the turbocharger only, and does not include any parts or components associated with, attached, or connected to the turbocharger unit. At the sole discretion of the G-Pop Shop, customer provided used core parts may or may not be covered by warranty if they fail. This limited warranty does not cover incidental or consequential damages or expenses of any kind. Our warranty provides only for the repair or replacement of any turbo part(s), as determined solely by us. Our warranty does not cover or provide cash or like refunds of any kind.

This warranty is also limited in that it does not apply to any turbo which has been subjected to oil related problems (most commonly oil starvation and/or oil contamination - which are both clearly owner/installer responsibilities), improper installation, foreign object damage, over-speeding of the turbo, misuse, neglect, accidents, any modifications made to the turbo by the purchaser, or if the turbo has been disassembled by anyone other than the G-Pop Shop.

In order to warranty a part or turbo, it must be returned to us for inspection in its "as-is" condition (not cleaned or disassembled). In some cases, we must forward the part or turbo to the manufacturer in order for them to do their own inspection. This isn't a long process, but does require a little time (about 7-10 days).


Too often, in the event of malfunction of a turbocharged engine, the turbocharger is immediately assumed to be at fault and is replaced. Frequently, the replacement unit soon fails, finally prompting an investigation into the real cause of the initial failure. Such a sequence of events is frustrating as well as expensive.


Stringent quality control makes it highly unlikely that a turbocharger could leave the factory, or our shop, incorrectly assembled, or not up to specifications. A "bad" turbocharger would operate badly almost from the moment of installation, but a turbocharger which has operated successfully for a period of time, and then fails, almost invariably fails because of a deficiency in the operation of the associated engine systems. Years of actual experience with service failures demonstrate the major cause of turbocharger failures to be faulty lubrication systems. Abnormal wear in the bearings or seals results from abrasive contaminants in the oil, or an insufficient supply of oil. Other systems, such as fuel and ignition, can also play a part in causing engine troubles in which turbocharger system malfunction is originally suspected.

The overall objective of trouble-shooting is to find the cause of trouble and take corrective action to prevent a recurrence. This objective must be kept in mind even while determining whether anything is actually wrong with the turbocharger system components, and just what is wrong, to enable repairs.

Even perfectly operational turbocharger system components cannot compensate for incorrect engine operating procedures, deficiencies in the engine oil supply, oil drain, ignitions, air induction, fuel, or exhaust systems, or for damaged internal engine components.
