Prelude Engines are not appliacble to this swap information
the wiki is here
Engines can be sourced from 90-01 Intgra, 99-2000 Civic Si, And Crv 95-01. Transmissions can only come from 90-01 integra Manual, and 99-00 Civic Si.
As well, if you request any engine/transmission applicable to these cars for your Local Japaneese Importer, he will provide you with a JDM compatible engine
Hasport Has mounts and axles readily availble.
you wil need a 90-93 intermediate shaft.
94-01 Integra /99-00 Si axles and intermediate shafts are too wide and hit and bind a bit
Hapsort Mounts Hydro or Cable transmission
Wiring can be transplanted from si Civic/CRX models from 86-91. you will need to depin and repin for the ecu. Dx models are either carbed or Dual Point injection. you may choose to transplant a full obd1 or obd2 firewall harness into the car. a good many of the plus are plug and play. specifics are way to detailed to go into into this post. if you choose to maintain the OBD0 wiring, you can add a jumper harness for obd1 conversion to use a newer ecu. obd0 ecu is only compatible with obd0 Distributor. Obd1 and Obd2 are compatible with either ecu/dizzy combo but not compatible with obd0.
