Stage III Camshaft for Honda D16Z6 SOHC VTEC
BXCM-20101-Z3 is a Stage III performance camshaft for highly modified Honda D16Z6 SOHC VTEC engines. It requires a coordinated engine build with upgraded valvetrain, cylinder-head machining and porting, high-compression pistons and ECU tuning.
Key Features
- OEM-spec chill-cast camshaft core.
- Stage III profile for highly modified to full-race engine builds.
- Intake duration 247 degrees and exhaust duration 230 degrees at 0.050 inch.
- The BXCM-20101-Z3 is an individual SOHC camshaft, not a pair.
Fitment
| Years | Make | Model | Submodel |
|---|---|---|---|
| 1992-1995 | Honda | Civic | EX |
| 1992-1995 | Honda | Civic | Si |
| 1993-1995 | Honda | Civic del Sol | Si |
These applications require the D16Z6 engine and the supporting modifications specified by BLOX Racing. The manufacturer also permits D16Y8 use with the appropriate BLOX cam gear; that engine-specific arrangement does not establish direct fitment to other vehicles. Verify piston-to-valve clearance before final assembly.

FAQ
What is the BXCM-20101-Z3?It is one BLOX Racing Stage III camshaft for a suitably prepared Honda D16Z6 SOHC VTEC engine.
Does this listing supply two camshafts?No. This is one camshaft for the specified single-overhead-cam application.
Can I fit it to an otherwise stock engine?No. BLOX requires upgraded valvetrain, head machining and porting, high-compression pistons and ECU tuning.
Does the engine need tuning?Yes. ECU tuning is required, and the camshaft must be degreed in before final installation.
Must piston-to-valve clearance be checked?Yes. The manufacturer specifically requires this clearance to be double-checked.
Can it be used in a D16Y8?BLOX states that D16Y8 use requires a compatible BLOX cam gear. Confirm the complete engine build and timing setup with your engine builder.
Is it CARB legal?The distributor lists this part as not CARB legal. The manufacturer describes non-exempt performance products as intended for off-road use.
Who should install and set it up?Use a qualified engine builder or technician who can check clearances, degree the camshaft and complete the required tuning.
Installation Instructions
- Confirm the D16Z6 engine and complete supporting build, then review the official Stage III technical sheet and factory service manual.
- Have a qualified engine builder inspect the valvetrain, cylinder head and piston-to-valve clearance before assembly.
- Degree the camshaft before final installation and set up the timing and valve clearance according to the verified technical data.
- Complete ECU tuning and check engine operation before performance use.
