Advanced Design Features for Peak Performance
- Anti-Detonation Grooves: Trap excess combustion pressure to prevent ring flutter and protect against hot spots during high-boost runs.
- Accumulator Groove: Collects blow-by gases in the second ring land, maintaining top-ring seal for better combustion efficiency.
- CP Groove (Constant Pressure): Equalizes ring pressure and keeps gas ports clear, reducing carbon buildup for sustained power.
- Dual Forced Pin Oiling: Delivers twice the lubrication to the wrist pin bushing, extending life in high-RPM scenarios.
- Hydro-Ground Skirt with Cam and Barrel Profiles: Minimizes scuffing, noise, and wear while promoting tighter clearances for quicker break-in and higher revs.
These elements combine to provide the thermal stability and ring seal demanded by 2JZ builders chasing track-proven results, outperforming cast alternatives in heat dissipation and load-bearing capacity.
