Performance Highlights

✅ Street-Friendly with Rapid Response

• 55mm/62mm turbine wheel + optimized A/R ratio for fast low-rpm spool-up, no obvious lag in daily driving
• 62mm compressor delivers continuous high-flow output between 3000–6500rpm, with a deeper and more powerful 5-cylinder exhaust note

✅ Track-Grade Potential & Stable Output

• Forged aluminum compressor wheel + stainless steel turbine wheel, high temperature resistance and anti-deformation, supporting continuous high boost pressure
• Heart-cut enlarged design, flow upper limit far exceeding the original, can break through 800 HP with full upgrades

✅ Original Compatibility & Hassle-Free Upgrade

• Retains the original turbo housing appearance, low-key and unassuming
• Oil passages, water passages and flange positions 1:1 matching the original, greatly reducing installation time
