That year, make, and model range is listed. Confirm the exact engine code, bore, stroke, rod length, pin size, cylinder head, compression target, and machine-shop measurements before ordering.

Are piston rings included with this 83.50 MM JE piston kit?
The official JE specification lists Ring Set Included as Yes. Confirm pins, locks, quantity, and any upgraded pin option in the What's Included section before assembly.

What must the machine shop measure before final assembly?
Verify finished bore diameter, piston-to-wall clearance, ring end gaps, deck height, piston-to-valve clearance, pin fit, bearing clearances, and final compression ratio for the intended fuel, boost, and power level.

Installation Instructions

Use the current JE Pistons instructions for part number 255773 and the engine builder's measured assembly specifications. A qualified machine shop must verify bore finish, clearances, ring gaps, pin fit, lock installation, orientation, balance, deck height, valve clearance, compression ratio, lubrication, and break-in before operation.

Mazda Miata Parts and Accessories

Mazda Miata Parts and Accessories

Choose Mazda Miata gauge mounts and engine accessories by generation, interior layout and installed engine. A-pillar pods and crankshaft dampers have very different application requirements. Gauge Pods and Interior Mounting Compare the model-year range, pillar shape and gauge count. Single, dual and triple pods provide different arrangements; 52mm and 2-1/16-inch references still require the exact gauge and mount dimensions to agree. Review attachment instructions, wiring clearance and the interior safety equipment before installation. The pod is a mounting component and should not be assumed to include gauges or sensors. Crankshaft Damper Configuration For a 1.8L damper application, compare belt grooves, pulley alignment and the trigger-wheel arrangement. Options described with and without an OEM trigger wheel require separate selection. Confirm whether the stated belt guide is included and which existing components must be retained. An engine conversion needs review against the ac...

Mazda MX-5 Miata Parts and Accessories

Explore Mazda MX-5 Miata intake, exhaust and brake options by generation and engine. Keep earlier 1.8L damper configurations separate from later 2.0L intake and chassis applications. Intake and Axle-Back Exhaust Choices Compare an intake’s exact year and engine coverage, heat-shield contents and sensor connections. Polished and black finishes should be compared only after the underlying part application is established. For a single-exit axle-back exhaust, check rear-section connections, outlet position, material and supplied hardware. Confirm clearance and compatibility with the existing exhaust and body configuration. Dampers and Brake-Service Details Damper selection depends on crankshaft application, belt grooves, pulley alignment and trigger-wheel configuration. A 1.8L damper reference is not a substitute for identifying a later 2.0L engine’s drive arrangement. Match rotor geometry and caliper package separately at each axle. For a brake hose, identify left/right and front/rear ...
