It all depends on what motor. If you go vtec then you will need a different ecu, and you will have to run the wires for it.

If you go obd0 d-series then you just use the stock engine wiring harness and trans and mounts.

If you go obd1 d series (d16z6) then you need to do some wiring. You can use the same motor mounts and trans.

If you go b series non-vtec then i would suggest you find a 90-91 integra and take the whole motor, trans, ecu, and shift linkage from that car. You will have to shorten the shift linkage by 2-3/8. You will have to get a mount kit too. Dont qoute me on this but I have been told by a couple poeple here locally that you can use the da integra motor mounts but the motor sits too high for the hood too shut. My buddy is doing this so i will find out for sure if it will work or not.


If you go b series vtec then you will same as above in the non-vtec b series but you will need more wiring, and a vtec ecu.
