Choosing the Right Part
  • Engine code: Match the part to your engine code, for example EJ20, EJ22, EJ25, EJ255, EJ257, FA20, G16E-GTS, RB26DETT or VR6 2.8L. Some parts suit only some variants. For example, the Fluidampr RB26DETT damper is listed for the Phase-2 engine (R33/R34 GT-R).
  • Chassis code: Check the chassis code in the product title, such as GC/GD/GE/GH/GR/GV/VA (WRX/STI), BE/BH/BL/BP (Liberty GT), ZC6/ZN6 (BRZ/86), GXPA16 (GR Yaris), GZEA14 (GR Corolla), FK8/FL5 (Civic Type R) or BK/BL (Mazda 3 MPS).
  • Bore size: Pistons, piston rings and head gaskets are listed by bore, such as 99.50mm, 100mm or 101mm. Some ring sets are oversize, for example 100mm +0.13mm.
  • Piston specifications: Piston listings may include dish volume (for example -14.00cc or -15.10cc) and compression height. Check these against your build plan.
  • Bearing details: Bearing sets can be listed by journal size (for example 52mm), thrust position, size (for example STDX) and whether they are coated.
  • Gasket thickness: Head gaskets are listed by thickness and bore, for example .055" with an 83.5mm bore.
  • Cam timing system: Adjustable cam gears may suit only one system. For example, the Tomei set is listed for single AVCS engines.
Installation & What You'll Need

Installation by a professional is recommended for all engine internal components. Always follow the manufacturer's instructions and specifications for your part.

Before ordering, confirm the quantity your engine needs. Some items are sold individually, such as single head gaskets and piston ring sets for a single piston, while others are sold as full sets or pairs.

FAQ

Are pistons and rings sold as sets or individually?
Both are available. Piston sets and kits are sold as a set, while some ring sets are sold for a single piston. Check the product title before ordering.

How do I choose the right bearing set?
Match the engine code, then check the listed journal size, thrust position and bearing size (such as STDX) against your engine's requirements.

Do you stock genuine parts for the Toyota GR Yaris and GR Corolla?
Yes. The range includes Toyota Genuine and OEM G16E-GTS parts such as timing chains, tensioners, sprockets, camshaft timing valves, rocker arms, hydraulic lifters and an overhaul gasket kit.

Does Chicane install engine parts?
No. Chicane Australia supplies parts only. Installation by a professional is recommended.
