FAQ

Q: What makes this Stage 3 vs Stage 2?
A: Stage 3 features a premium ceramic ball bearing turbo with billet wheel rated at 650HP (vs 500HP for Stage 2), larger S3 intercooler, and upgraded components throughout. It's designed for 500-650+ HP builds with built motors.

Q: Will this fit my H23A1 engine?
A: No, this kit does NOT fit H23A1 (non-VTEC). It's designed for H22A and F20B VTEC engines only.

Q: Do I need an alternator relocation bracket?
A: Yes, absolutely required for this kit. The turbo manifold requires relocating the alternator. Bracket sold separately.

Q: Can I run this on a stock motor?
A: You can run lower boost (10-12 PSI, ~450HP) on a stock H22A4 with proper tuning, but this kit is designed for built motors. Stock H22A1 should not exceed 400HP.

Q: What's the advantage of ceramic ball bearing?
A: Faster spool, less lag, better oil flow, longer turbo life, and can handle higher RPM compared to journal bearing turbos. Essential for high-HP builds.

Q: Do I need a standalone ECU?
A: Yes, for this power level you need Hondata S300, Neptune RTP, AEM Infinity, Haltech, or similar. Stock ECU cannot handle this power safely.

Q: What power can I realistically make?
A: Stock H22A4 (conservative tune): 400-450HP. Built motor (forged internals): 500-650HP. F20B: 450-550HP built. Always tune conservatively and monitor AFR.

Q: Is this worth the upgrade over Stage 2?
A: If you're building for 500+ HP, yes. The ceramic ball bearing turbo rated at 650HP, billet wheel, and larger intercooler justify the premium. For 400-450HP builds, Stage 2 is sufficient.

Professional installation and tuning required. May require fabrication or welding. Built motor recommended for power levels above 450HP. Alternator relocation bracket required (sold separately).
