JDM 98 Spec B18C-R engine swap guide for any 99-00 CX/DX Civic HB

Mounts:
· JDM-R front passenger side mount
· P54 Del Sol front driver’s side mount bracket (Honda P/N 38930-P54-000) if you wish to keep A/C. Use the JDM-R front driver’s side mount bracket if you don’t.
· 99-00 Civic Si driver’s side upper engine mount bracket (Honda P/N 11910-P30-000) w/ 99-00 Civic CX/DX driver’s side upper mount and frame mount.
· 99-00 Civic CX/DX passenger side transmission mount and frame mount.
· 99-00 Civic Si rear engine mount bracket (Honda P/N 50827-S04-N10) w/ 99-00 CX/DX Civic rear frame mount.

Wiring:
· Si Wiring harness
o IAT sensor plug needs swapped from stock JDM harness to Si harness and wires extended.
o Vehicle Speed Sensor plug needs swapped from stock JDM harness to Si harness.
o EVAP sensor plug needs swapped from stock JDM harness to Si harness and wires extended.
o Plastic mounting bracket for injector plugs needs swapped from JDM Harness to Si harness.
o Borrow the EVAP sensor and 2 way valve from the stock CX/DX motor and install/connect the vacuum lines and sensor plug.

· 98+ Spec JDM-R ECU
o An OBD2b -> OBD2a jumper harness is needed for the OBD2b 99-00 Si harness to be usable with a 98+ Spec JDM-R ECU(unless you want to swap plugs and wire everything yourself).

Fuel supply:
· Replace the fuel feed line from the filter to the rail and also the fuel return hose from the rail to the hard line runnning under the vehicle w/ 98-01 ITR units.
· Replace the OEM fuel pump with at least an OEM 98-01 Integra GS-R/ITR fuel pump.

Exhaust:
· A 2.5” converter is needed for the JDM 4-1 header. Just have a muffler shop cut your exhaust to length and weld on the converter.

Power Steering:
· Replace the OEM CX/DX PS pump with the JDM-R PS pump provided with the swap. The OEM Civic power steering line and return hose will connect to the JDM-R pump with no hassles.

Cooling:
· Fluidyne aftermarket radiator designed for the 96-00 Civic, but I've been told that a DelSol DOHC VTEC radiator will work just fine.

Misc parts:
· 98-01 ITR radiator hoses
· 98-01 ITR TB gasket(Recommended so you don’t break the TPS during install)
· 98-01 ITR Exh. Manifold gasket
· 98-01 ITR throttle cable(The stock cable will work, but it’s quite a bit longer than is needed)
· 98-01 ITR axle seals
