Honda Civic Turbo HR-V L15B7 Forged Piston Kit 73mm 2016-2021

Honda L15B7 Forged Piston Kit — 73.00mm Bore | Earth Dreams Turbo Performance

Built for the boost your Earth Dreams engine was designed to handle — and then some.

Engineered for the L15B7 turbocharged platform, this heavy-duty forged piston kit is built to withstand increased boost pressure without compromising reliability. Manufactured from 4032 forged aluminum, it delivers the strength and thermal stability that stock cast pistons simply weren't designed for — making it the go-to upgrade for tuned Civic, HR-V, and CR-V 1.5T builds.

Whether you're running higher boost on a stock turbo or stepping up to a larger unit, this kit gives your bottom end the durability to match your power goals.

Why Choose This Kit

• Forged 4032 Aluminum — Handles elevated boost pressure and cylinder loads far beyond stock cast piston limits
• 10.3:1 Compression Ratio — Tuned for a strong balance of power and reliability under boost
• Earth Dreams Turbo Specific — Purpose-built for the L15B7, not a generic adaptation
• Direct Fit — Matched to factory bore and pin specs for a precise, reliable installation

Fitment

• Honda Civic Turbo (2016+)

Confirm your engine code (L15B7) and current turbo/boost setup before ordering — pairing pistons with the right supporting mods matters for reliability.
