Adriano, what info exactly are you after?all depends on budget and what you can do yourself.
For ECU you can just go the standard B18C item with a OBD-1 conversion which just means a few changes to the wiring harness really-

For the gearbox I got a B16 cable box from a CRX as my motor didnt come with a gearbox. this is probably the easiest way to do things but cable boxes are becoming rarer these days so you could always do a hydraulic conversion using a kit from Hasport

If you are really lazy you can just use your standard box, but the ratios are pretty average for VTEC.
