WISECO Forged Pistons

Wiseco Performance Products exceptional quality and forging process enables them to produce state of the art forgings in typically 2618 T6 alloy for race applications and 4032 T6 alloy for performance street and race engine builds.

The unique squeeze forging process allows grain flow to be optimized, this add's toughness, impact resistance and fatigue strength. These are all key requirements to produce a race engine piston.

Speedfactor has carried a range of Wiseco pistons ever since they opened for business in 2001.

There are many applications covered in whats known as shelf stock (catalogued) for common Japanese and some European engines plus a huge range of V8 performance options.

We are now one of New Zealand's leading suppliers of import engine pistons.

Also working closely with Wiseco, we offer a comprehensive data base of custom applications, purpose built unique pistons that can be made to order for your specific requirement.

most of our custom pistons are produced in 4032 material

We carry a range of replacement piston ring sets to suit the Wiseco range and these are sometimes also compatible with JE and CP pistons.

Check with us for pricing and applications if you are wanting a race bred piston and ring set designed for use in some of the harshest environments.

We carry H beam connecting rods for the majority of piston offerings as well as most engine components to complete a comprehensive rebuild.

With the growing requirement for specific and unique engine developments and with the introduction of Ethanol fuel etc, there has been a need to produce many custom pistons to fill the market sector

We generally make all the custom applications in 4032 for performance and race applications and utilise specific and upgraded ring and pin components to maximize the longevity for these hard working engines
