Supplied complete with wrist pins, wire locks and a matched JE Pro Seal ring set.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThese are forged race pistons and they need machine work to fit.\u003c\/strong\u003e The block is bored and honed to suit them and the piston-to-wall clearance is set to specification. \u003cstrong\u003eJE supplies the full specification with the set\u003c\/strong\u003e, and that is what your machinist works to. Budget for that work when you plan the build — these are not a part you drop into a standard engine over a weekend.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Hyundai i30 N 2018 on, Veloster N 2019-2022, Elantra N 2022-2026 and Kona N 2022-2023 — 2.0L Theta II turbo. JE cuts this piston at a 30.00 mm compression height on a 22 mm pin for the stock 146 mm rod and 86.0 mm stroke, which are the factory figures for these engines. We sell it for these cars on that basis and on our own engine-building experience with them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJE make this piston in more than one bore size.\u003c\/strong\u003e Tell us what your block measures, or what your machinist is planning, and we will make sure the right one comes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is a full-floating pin.\u003c\/strong\u003e Check that your rod small ends are set up for one. If you are running the factory rods, have them measured first — they may need bushing or honing, and that is more machine work to budget for.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRunning more than about 2 bar of boost?\u003c\/strong\u003e A reinforced piston pin is the accepted upgrade at that level and is a separate part. Tell us your target and we will specify it with you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAbout compression ratio.\u003c\/strong\u003e We deliberately do not print one. The dish volume is a property of the piston and is given below, but the ratio your engine finishes at depends on your cylinder head and head gasket — any figure quoted on a box assumes a stock-thickness gasket, so a thicker one changes it. Tell us your build and we will work it out with you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDetails:\u003c\/strong\u003e set of 4 pistons; compression height 30.00 mm (1.181 in); wrist pin 22 mm (0.866 in), included; round wire locks, included; dish volume minus 5.9 cc, inverted spherical; weight 305 g per piston; JE Pro Seal ring set included, 1.0 mm top, 1.2 mm second and 2.8 mm oil; 2618 T6 forged aluminium; Forged Side Relief slipper skirt with coating. JE notes the design accepts turbo and nitrous. Bore and clearance figures come on JE's own specification sheet with the set.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHave the piston-to-valve clearance checked at assembly.\u003c\/strong\u003e JE does not publish valve pocket or crown geometry for this piston, and these engines are direct injected and tight. Clay-check it on the bench before the engine goes together.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e ON ORDER at our distributor as of 5 November 2026.
