The FAJS 48 is an affordable and extremely potent carburetor, perfect for those building a true race engine, rally car, or an aggressive street build where maximum airflow and peak performance are essential. Important Note: Although FAJS markets and names this carburetor as a "48 DCOE", it is technically and structurally a reproduction of the classic Weber 48 DCO. This is crucial to keep in mind when ordering specific internal spare parts.
With its large 48 mm throttle butterflies, this carburetor is highly capable of feeding large displacement engines running aggressive camshafts. The carburetor comes complete with air horns (trumpets, approx. 60 mm long) and a standard linkage mechanism, making it adaptable for most high-performance applications.
Included Base Jetting (Factory specs):
- Choke (Venturi): 40 mm
- Auxiliary Venturi: 4.5
- Main Jet: 155
- Emulsion Tube: F2
- Air Corrector Jet: 200
- Idle Jet: 65F8
- Pump Jet: 45
- Exhaust Pump Valve: 40
- Needle Valve: 2.50
Important Installation Advice: For the carburetor to function flawlessly and to avoid flooding, it is critical that the fuel pressure is kept in check (maximum 0.25 Bar / 3.6 PSI). We strongly recommend using a high-quality fuel pressure regulator, such as the Filter King, during installation. Please note that the jetting provided is a factory baseline; fine-tuning the jets to perfectly match your specific engine will likely be necessary.
