BLOX Racing Ti Retainers for B16A - B18C1-5 (1.6L - 1.8L DOHC VTEC) / H22A 2.2L DOHC VTEC
BLOX Racing Ti Retainers are CNC-machined titanium valve spring retainers designed for B16A B18C1-5 and H22A DOHC VTEC cylinder heads in select Honda Civic Integra and Prelude Acura Integra models. These retainers replace heavy OEM steel units to slash valvetrain reciprocating mass by over 190 grams total and enable revs beyond 9000 RPM without valve float. Track enthusiasts rely on them for sustained durability in high-boost high-RPM competition engines.
Key Features
- 6AL-4V Titanium Construction: Aircraft-grade material delivers high strength at low weight for precise valve control during extreme boost and RPM loads
- Weight Savings Per Retainer: 3.9 grams each compared to OEM 10 grams cuts total valvetrain mass by 190 grams for faster engine response and revving
- Dual Valve Lock Grooves: Secure hold for OEM Honda locks and leading aftermarket options prevents movement under aggressive valve lift and duration
- Precision CNC Machining: Perfect balance and OEM dimensions allow direct drop-in fit in B-series and H-series VTEC heads with no modifications
- High RPM Durability: Rated for 10000+ RPM with matched dual valve springs maintains stability for consistent power in drag and circuit racing
Product Notes
- Set of 16 retainers equips one full DOHC VTEC cylinder head
- Direct OEM replacement preserves stock valvetrain geometry while adding performance weight reduction
- Packaged in protective foam insert inside 6 x 4 x 2 inch box prevents shipping damage
Installation Notes
- Professional installation recommended.
- Cylinder head requires full disassembly for valve access
- Works with OEM Honda dual valve locks and springs up to 100lb seat pressure
