Yes: the B-series hydraulic-clutch manual transmission (cable-to-hydraulic conversion) from the Integra GS-R (1994-2001) fits the Integra (DA) (1990-1993) — moderate difficulty, modifications required.

Installation notes

Yes — a hydraulic-clutch B-series manual transmission such as the one from a 1994-2001 Integra GS-R (DC2) fits a 1990-1993 Integra (DA) with a hydro transmission mount, a hydro rear bracket and a cable-to-hydraulic clutch actuator. Hasport sells a 90-93 Integra transmission mount specifically for the B-series hydraulic transmission. Innovative lists its 49350 kit for the 90-91 DA9 and 92-93 GS-R with B18A/B17A engines and a hydraulic transmission, and says it also works for cable-to-hydraulic conversions. This is the usual route when a DA owner wants a later hydraulic gearbox.

Required modifications

Transmission mount: a 90-93 Integra mount made for the hydraulic B-series transmission (Hasport DAHYRH, manual chassis only). Rear bracket: Hasport EFRB-HY is the B-series rear engine bracket for 88-91 Civic/CRX and 90-93 Integra with the hydraulic-style transmission. Clutch: the DA uses a cable clutch, so a cable-to-hydraulic actuator is needed (Innovative 41000 or 41001); Innovative's 49350 DA kit covers the cable-to-hydraulic conversion but is sold without the actuator in the Hybrid Racing listing. Axles and shift linkage must suit the hydraulic B-series gearbox.

Caution

Important caveats

  • Hasport's DAHYRH mount is listed for manual-transmission chassis only.
  • Innovative lists its DA hydro kit for B18A/B17A engines; confirm the timing-side post mount if you are also changing the engine.
  • Hasport and Innovative split the 90-93 Integra into 90-91/92-93 GS-R and 92-93 non-GS-R versions for some mounts; order by your exact car.
  • Innovative's 49350 kit is sold without a clutch actuator in the Hybrid Racing listing; a cable-to-hydraulic conversion also needs a B-series actuator (41000 or 41001).
