Pistons

• Forged piston sets: Engine-specific sets from Nitto, CP Pistons, JE Pistons (FSR), Manley and Mahle Motorsport (including coated and PowerPak options).
• Stroker and de-stroke pistons: Pistons made to suit a different crankshaft stroke, offered for engines including the RB25DET NEO, RB26DETT, RB30, SR20DET, EJ20, EJ257, 4G63 and Barra 4.0.
• Piston ring sets: Ring sets from CP Pistons and Mahle, including file-fit rings for setting your own end gaps.
• Wrist pins: Includes Manley 9310 steel wrist pins for EJ25 piston sets.

Start with your engine code, then match the piston specifications to your planned build.

• Engine code and chassis: Nissan RB25DET (R33, WC34), RB25DET NEO (R34, WC34), RB26DETT (R32, R33, R34 GT-R), RB30 SOHC (VL Commodore, R31 Skyline), RB30 DOHC head conversions, SR20DET (S13, S14, S15) and VR38DETT (R35 GT-R). Toyota 1JZ-GTE, 2JZ-GTE and G16E-GTS (GR Yaris GXPA16, GR Corolla GZEA14). Subaru EJ20, EJ205, EJ255 and EJ257 (WRX, STI, Forester, Liberty GT). Mitsubishi 4G63 (Lancer Evolution IV–IX) and 4B11T (Lancer Evolution X, Lancer Ralliart). Ford Barra 4.0 (Falcon BA, BF, FG, FG X and Territory SX, SY, SZ). BMW S55 (F80, F82, F87), Audi DAZA/DNWA 2.5T FSI and Honda K20C1 (Civic Type R FK8/FL5).
• Bore size: Sizes in this range include 84mm, 92.50mm, 99.50mm and 100.00mm. Ring sets may be listed with an oversize, such as 100mm +0.13mm.
• Dish volume and compression ratio: Dish volume is quoted in cc (for example -14.00cc, -15.10cc or -26.00cc). Some sets also list a target compression ratio, such as 8.2:1 or 10.2:1.
• Compression height, stroke and rod length: These must suit your crankshaft and connecting rods. Stroker and de-stroke pistons are designed for a different stroke than the factory one.
• Wrist pin and rings: Pin diameter (for example 22mm or 23mm) and ring sizes (for example 1.0/1.0/2.0mm) need to match the piston.

Installation by a professional is recommended. Fitting forged pistons usually means measuring the bores and machining the block to the clearance the piston manufacturer specifies. File-fit ring sets also need their end gaps set to suit your build.

A piston change is often done alongside other bottom-end and head work, so check our rods, cranks and bearings, gaskets and head studs and engine fasteners. Some listings are complete piston sets and others are single pistons, ring sets or pins, so check the kit contents on each product.

What is a stroker piston?
A stroker piston is designed to suit a crankshaft with a longer stroke than the factory one. Check the listing for the crank and rod combination it is made for.

Do piston sets include rings and wrist pins?
It depends on the listing. Check the kit contents on each product. Ring sets and wrist pins are also available separately in this collection.

What does the cc figure on a piston mean?
It is the dish volume of the piston crown. With all else equal, a larger negative figure means a larger dish and a lower compression ratio.

Which piston brands does Chicane carry?
This collection includes Nitto, CP Pistons, JE Pistons, Manley and Mahle Motorsport.
