Wiseco Nissan Turbo +14cc Dome 1.181 X 86.50mm

High Performance Piston Pins

Automotive Forged Piston Advantage
Wiseco leads the performance aftermarket by producing the highest quality forged pistons for domestic automobiles, sport compact and racing applications right here in the USA. Wiseco is unique because we forge all of our own pistons in house, and produce all of our own forge tooling right here in the USA. This allows us to control all aspects of our manufacturing process from raw bar to skirt coating finished parts.

In addition, in-house dyno testing gives Wiseco the ability to develop state-of-the-art technology such as new shapes, coatings, and components, and lead the industry through rigorous R&D. Linking all segments of Wiseco's organization through design, testing, manufacturing, and distribution allows us to fulfill market needs with minimum lead-times.

Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.

Piston Engineering / ArmorGlideT Coating
Wiseco's detailed skirt shapes and profiles are very specific to each application. Variable cam programming software developed in house allows Wiseco to produce high-performance shapes unique to only Wiseco. The skirt shape (barrel/cam) is one of the most functional areas on the piston, and provides stability and smooth operation in the cylinder bore. Stability is important for proper ring seal, reduced friction, and quiet operation. Each skirt shape is designed for a specific running clearance, based on coefficient of thermal expansion of the piston alloy. Some forging alloys expand more than casting alloys, but each Wiseco piston is designed with the proper installed clearance to produce the most power, least wear, and best seal at running temperature, for each application. Comparing installed clearances on cast vs forged parts is not indicative of the running clearance at temperature. Wiseco engineers have a strong background in all forms of racing applications, and produce the best shapes and designs in the industry.

Some of our forged pistons offer our new ArmorGlideT skirt coating, which is the result of testing, development, and benchmarking through Wiseco's rigorous in-house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Not only is ArmorGlideT a high-tech lubricant that reduces friction, but it also allows the piston to be fitted tighter within the bore allowing a better ring seal and reduced noise from piston rock.

Custom Automotive Pistons
Wiseco engineers specialize in building custom forged pistons to your exact specifications. These pistons are made using the exact same forging process as our shelf stock parts only they are built from the ground up using specifications or example pistons given by the customer. We have been making custom pistons for drag racing, circle track, autocross, road race, rally, and others for decades so you can trust us with a quality build. We pride ourselves in being able to manufacture just about any piston when other companies may so no because it does not fit into their mold of manufacturing. Wiseco's process is built to handle just about any project you can throw at us. If you would like a custom piston built please reference out customer service page and fill out a custom piston request and we will notify you with a price quote and minimum order quantity.

Domestic Auto / Sport Compact Piston Features
Wiseco domestic auto and sport compact pistons are forged and machined in-house and receive a full compliment of power enhancing features. Light weight forgings, millimeter ring packs, extra-strength forgings, gas ports, skirt coatings, offset pins, and a variety of other features are available to insure each engine exceeds our customer's expectations. Optimized skirt profiles minimize rock and provide long skirt life in stroker applications.

All machining is done on the newest CNC equipment to insure the tightest tolerances in the industry. Our Wiseco domestic auto and sport compact pistons are top of the line performance parts, built for the demanding consumer that wants nothing but the best. Some of our sport compact pistons are even matched with high quality NPR Steel nitrided rings with napier style 2nd rings. Applications are listed for Chevy, Ford, Chrysler, Pontiac, Honda, Acura, Mitsubishi, Toyota and much more.

Pro Tru Piston Features
Pro Tru pistons are forged and machined in-house and are designed to make excellent power with a long life and the best value. Dedicated forgings require minimal machining and insure a strong, lightweight piston at minimal cost. Design work is very detailed to insure the latest piston skirt profiles for minimal rock, tight clearances, and long skirt life.

All machining is done on the newest CNC equipment, insuring excellent machining at tight tolerances. Most Pro Tru pistons use a 4032 alloy, however big block pistons and certain small blocks designed for nitrous or boost receive the stronger 2618 alloy. Pro Tru pistons are generally made for a budget minded consumer in the domestic automotive market running a Buick, Chevy, Ford, Dodge or Chrysler.
