CP Pistons Forged Kits for LS, Coyote, 2JZ, K20 and RB26 Builds

What This Collection Covers

CP Pistons forged components are designed for engine builds that need carefully matched piston specifications and ring sealing. The selection covers piston kits, replacement ring sets and wrist pins for popular four-cylinder, six-cylinder and V8 combinations.

Built for verified applications

Use the fitment details and product specifications on each listing to confirm the correct application before ordering. Components that look similar can use different sizes, mounts, threads or clearances.

Forged Pistons for Boost and Compression

Build around the correct specifications

A forged piston kit must match the finished cylinder bore, combustion chamber, deck height, rod length and intended compression target. Review the listed bore, compression height, dish or dome volume and pin dimensions with your engine builder before ordering.

Piston Rings and Cylinder Seal

Use the matched ring package

CP ring sets and replacement rings are specified for particular piston families and bores. Confirm the exact piston part number, ring groove dimensions and cylinder finish, then set end gap to the engine builder or piston manufacturer recommendation for the application.

Import and Sport Compact Platforms

Popular engine families

Current CP Pistons listings include options for Honda K20, Acura B18, Toyota 2JZ-GTE, BMW B58 and Nissan RB platforms. These engines demand attention to bore, compression target, turbocharger use and fuel choice.

Machine Shop Planning

Confirm details before assembly

Pistons are a core engine-build decision. Give the machine shop the exact piston kit before final bore and hone work, then check piston-to-wall clearance, ring end gap, pin fit and deck clearance as part of the build plan.

Common Questions

What does CP Pistons make?

CP Pistons makes forged pistons, piston-and-ring sets, replacement rings and wrist pins for high-performance engine builds.

Which engines are covered in this CP Pistons collection?

Current listings include applications for Honda K20, Acura B18, Toyota 2JZ-GTE, BMW B58 and Nissan RB engines, among others.

How do I choose the correct piston bore?

Order from the finished cylinder-bore specification supplied by the machine shop. The cylinder should not be final-honed without the piston specification.

Why does compression ratio matter?

The piston compression ratio must work with the combustion chamber, head gasket, camshaft, fuel and boost plan to achieve a safe engine combination.

Do piston kits include rings?

Many CP piston kits include a ring set, but contents vary by part number. Confirm the product description and use the listed replacement rings when needed.

Can I use forged pistons in a turbocharged engine?

Forged pistons are commonly chosen for boosted builds, but the exact piston, clearance, ring gap, tune and fuel strategy must suit the engine plan.

What is a compression height?

Compression height is the distance from the wrist-pin centerline to the piston crown. It must match the rod, crankshaft and deck-height combination.

Should I replace wrist pins with the pistons?

Use the pin supplied or specified for the piston kit. Replace any worn or incorrect pin rather than mixing unmatched components.

Can I install pistons without machine-shop work?

Most forged piston builds require careful measurement, machining and assembly checks. Use a qualified engine builder for final fit and clearances.
