Installation notes

Yes — the H22A engine and manual transmission from a 1993–1996 Honda Prelude VTEC (BB1) fits a 1990–1993 Acura Integra (DA) with Innovative Mounts' DA H/F-series conversion kit, the Prelude H22 post mount 11910-P13-000 and H-swap axles. Innovative says the kit installs an H22 with little modification and includes a clutch actuator that works in the same plane as the clutch release fork. Insane Shafts H22/H23 swap axles are listed for DA and DC Integras. Innovative's EG/DC kit notes say 90–93 Integra axles work with an H-series gearbox when the right axle gets a Prelude/Accord inner CV joint.

Required modifications

Engine mounts: Innovative Mounts 90-93 Integra H/F-series conversion kit (part 29354 on Hybrid Racing's listing), which includes a clutch actuator and needs the 92-01 Prelude H22 timing-belt post mount, Honda 11910-P13-000. Innovative also sells an H22 alternator relocator for this kit. Axles: Insane Shafts H22/H23 swap axles are listed for DA/DC Integra; Innovative's EG/DC H-series kit page says 90-93 Integra axles can be used with an H-series gearbox if the right axle gets a Prelude/Accord inner CV joint (the Prelude/Accord inner spline shaft is slightly longer), and lists a 1990 manual Accord intermediate shaft as an option for the left side. Also needs an H-series shifter setup and ECU/harness.

Caution

Important caveats

  • Hasport does not list an H-series kit for the DA Integra; the mount source here is Innovative Mounts only.
  • Honda post mount 11910-P13-000 is required and sold separately.
  • Alternator clearance may need Innovative's H22 alternator relocator.
  • Axle details (Prelude/Accord inner CV, 1990 Accord intermediate shaft) come from Innovative's EG/DC kit notes; confirm with the seller for a DA.
