Re: Zc dohc crank sprocket timing belt washers

yes, you can use ones from the D16 SOHC, however, depending on engine years, both D16 SOHC and DOHC ZC engines came with crankshafts with different diameter front snouts (where the gear goes on) -...

Re: CRX Si Stalling

the ECU does store the codes and they remain there until physically removed by cutting off power to the ECU - the CEL will turn off when the ignition is shut off but the codes remain

Re: Complete D16A6 swap from a D15B2

you would need to use the engine wiring harness that is in your hatch and do the DPFI to MPFI wiring changes - the MPFI engine harness will not plug into the DPFI chassis harness, and the DPFI...

Re: Making D15b2 with D16Z5

Injector Resistor Box – One from any Honda with Multi Point Fuel Injection will work, but one from 88-91 CRX/Civic is preferred since it bolts correctly into the right location.
