Download Part # 307-05-0290 Racing Intake Manifold for • 1999-2000 Honda Civic Si • 1997-2001 Acura Integra Type-R • 1992-1993 Acura Integra GSR • 1994-1997 Honda Del Sol DOHC VTEC. Removal 1. Relieve fuel pressure by loosening banjo bolt on top of fuel fi lter. Disconnect the fuel line at fuel rail. It is recommended that the washers be replaced. Next, disconnect the fuel injector harness holder and unbolt. Disconnect hoses from fuel pressure regulator (FPR). 2. Disconnect intake tubing/pipe from throttle body. Next, disconnect all hoses leading to intake manifold and throttle body, including throttle cable bracket on manifold. On throttle body, disconnect throttle positions sensor (TPS) and map sensor. 3. Unbolt manifold bracket from engine block and intake manifold. This bracket will not be used in assembly and installation. Remove intake manifold, throttle body, and fuel rail as one unit. Inspect intake manifold gasket. Replace as needed. Make sure to note all disconnect hoses and sensors. 4. Unbolt throttle body from intake manifold; inspect throttle body gasket for damage. Replace as needed. Unscrew throttle body bolts from fl ange. Remove fuel rail assembly. 5. From factory intake manifold, unbolt and remove idle air control (IAC) valve, intake air temperature (IAT) valve, and O-rings. Inspect O-rings and replace as needed. Unscrew intake manifold bolts from fl ange. *For 99-00 Civic Si: IAT sensor is located on intake tubing/pipe. Evaporative emission (EVAP) purge control solenoid valve is located on fuel rail. Disconnect hoses leading to charcoal canister and manifold. Assembly 1. Screw throttle body and intake manifold bolts into new manifold fl ange. Bolt on throttle body onto new manifold. Make sure that when lining up throttle body gasket, the U-shaped portion faces top-left-corner of fl ange. 2. Bolt on IAC valve, IAT valve, and O-rings onto new manifold. Install fuel rail assembly, making sure O-rings are properly and securely positioned to prevent fuel leakage. 3. Bolt on manifold-throttle body-fuel rail assembly back onto cylinder head, making sure that the manifold gasket is positioned properly and securely. Connect EVAP purge control solenoid valve. In cases where the EVAP solenoid valve does not remount to a factory location, it is recommended that the unit be zip-tied to a secure location. a. For 1992-1995 vehicles: EVAP valve must be secured. One hose will connect to the charcoal canister and the other hose will connect at the small vacuum fi tting on the rear of the manifold. b. For 1996-1997 vehicles: EVAP valve must be secured. A T-fi tting must be placed at the PCV hose fi tting to reconnect the PCV hose and EVAP valve hose. c. For 99-00 Civic Si: To reconnect the EVAP valve hose to new manifold, it is required that a 1/8-pipe tap be used to re-tap thread the sensor bung located on the #2 cylinder intake runner. Place a 1/8×3/8 bung fi tting to reconnect the EVAP valve hose. d. For Type-R: EVAP valve is located along fi rewall. All connections are same as factory. 4. Bolt on and connect fuel injector harness holder and hoses. Connect TPS, map sensor, and fuel line. The FPR hose will connect to the small vacuum fi tting on the front of the manifold. Tighten banjo bolt on top of fuel fi lter. 5. Connect battery and replace coolant. 6. Any unused bungs can be capped off by using vacuum caps.
