Honda Integra Type R Civic VTi B18C Forged Piston Kit 81mm 1995-2000

Honda B18C Forged Piston Kit — 81.00mm Bore | 12.0:1 High Compression VTEC

The engine that made VTEC legendary — built to make it hit even harder.

Purpose-built for the iconic B18C, this forged piston kit is designed for enthusiasts chasing the high-revving, naturally aspirated character that made this engine a legend. A 12.0:1 compression ratio sharpens throttle response and maximizes VTEC crossover power, while 4032 forged aluminum construction ensures the strength to handle sustained high-RPM abuse reliably.

Whether you're building a track-focused DC2, refreshing a tired SiR-G, or chasing maximum naturally aspirated output from your EK4, this kit is engineered to extract everything the B-series has to offer.
