Wiseco WK748M83 – forged piston kit for VW/Audi 2.0 TSI EA113

Key benefits

• 4032-T6 forged aluminium – lower thermal expansion than 2618, allowing tighter clearances and quieter operation on daily-driven engines.

• –11.25 cc inverted dish yields a street-friendly 9.25 : 1 compression ratio with the stock 92.8 mm stroke—safe head-room for big turbos and E85.

• ArmorGlide skirt coating minimises friction and cold-start scuffing.

• Asymmetrical FSR skirts: narrow thrust face cuts weight and drag, wider major skirt stabilises the piston at high rpm.

• Lateral gas ports keep the top ring sealed under heavy boost.

• Thick-wall 20 mm wrist pins included—built to survive 600 hp+ and nitrous shots.

• Delivered with a matched Wiseco ring pack, ready for assembly.

Typical applications

• Stage-3 + EA113 TFSI builds with large single or hybrid turbos.

• Drag, drift and time-attack engines targeting 600 hp or more.

• Conversions to E85 or methanol where lower compression and detonation resistance are essential.

Technical specifications

* With stock 92.8 mm stroke and EA113 cylinder head.

Kit contents

• 4 × Wiseco pistons WK748M83

• 4 × 20 mm wrist pins with wire locks

• Complete Wiseco ring set (1.0 / 1.2 / 2.8 mm)

• Installation sheet with clearance and torque data

Installation notes

• Piston-to-wall clearance: 0.04–0.05 mm for street use, 0.06 mm for boost levels above 30 psi.

• Gap rings to suit target boost (≈ 0.14 mm per 25 psi on the top ring).

• Verify valve-to-piston clearance with cam lifts ≥ 11 mm; deepen pockets if required.

• Use high-zinc 5W-40 / 15W-50 oil and shorten change intervals on engines exceeding 500 hp.
