Why We're Better
Warranty and Return Policies
Parts Department

We started serving customers in California in October 1982 as PanAsia, Inc.  We import used and rebuilt engines and related engine parts directly from Japan.  Within a short time we expanded our services nationwide.  To satisfy the increasing demand for remanufactured engines, in 1989 we merged with a Japan based company called U.S. Sunny Engines Enterprises, a company solely dedicated to remanufactured engines.

In October of 2001, the demand for quality engines motivated us to begin importing quality engine parts directly from the manufacturing suppliers.  Thus establishing PanStone, Inc., Automotive Engineering.  PanStone, Inc. is the only Japanese engine manufacturer that uses Original (OE Supplier) or Better (Performance and/or Heavy Duty) engine parts.  We believe you cannot make a quality engine without quality parts.  This attitude has made PanStone, Inc. the leader in producing remanufactured Japanese engines, and the only place to find your Japanese car’s original engine parts.  

Compare our prices, quality, and customer service and you will not find another that works harder to help you get, and keep, your car up and humming.
