Installation notes

Yes — the B17A1 engine and cable-clutch transmission from a 1992-1993 Integra GS-R (DA9/DB2) fits a 1988-1991 Civic (EF) with an EF B-series cable-transmission mount kit and the Integra-style timing-side post mount. Hasport says its EFB1 kit makes a B-series engine with cable-clutch transmission a bolt-in swap in the 88-91 Civic and CRX. Because the donor gearbox is cable-operated, the EF keeps its clutch cable and no hydraulic conversion is needed. The B17A1 is a 1.7 L DOHC VTEC rated at 160 hp; Wikipedia notes it came with a YS1 cable transmission that has a different input shaft and shorter final drive than other cable YS1 units.

Required modifications

Engine mounts: an EF B-series mount kit for the cable transmission (Hasport EFB1, or Innovative 19150/B19150). Innovative requires the 1990-1993 Integra timing-belt-side post mount (its part B59350) with its kit, and sells an EF B-series A/C bracket (59180) to keep the factory A/C. Clutch: no conversion, because both the EF and the DA Integra GS-R use a cable clutch. Wiring: EF B-swap adapter harness or a full engine harness. Axles and shift linkage must suit the B-series cable transmission.

Caution

Important caveats

  • Innovative states its cable kit needs the 1990-1993 Integra timing-belt post mount; a different post mount will not bolt up.
  • Innovative notes some LS/VTEC combinations and taller-deck B18C engines need minor trimming of the hood underside; the B17A1 uses the lower-deck B-series block.
  • Wikipedia lists the North American 1992-1993 GS-R under VIN DB2 while Innovative refers to the DA9/DB2 chassis; check the VIN of the donor car.
  • The 1990-1993 non-GS-R Integra B18A1 also used a cable transmission; this entry covers the GS-R B17A1.
