All Honda ECUs are interchangeable as long as they're from the same generation.

Generations are:
'88-'91 = OBD-0
'92-'95 = OBD-I
'96-'98 = OBD-IIa
'99-'00 = OBD-IIb

If your ECU is a different OBD, you need a conversion harness and it'll plug right into the existing ECU harness and then plug into your ECU. You can pickup a conversion harness at http://www.jdmshit.com

As far as the trans goes...yeah, it'll work..but make sure it's not a 4wd trans or you're going to have a gaping hole in the back where the rear wheel drive driveshaft goes into.

EDIT:
PS: Using a B20 ECU on a B18 will throw the fuel tables off - they use different fuel tables - it won't run optimally meaning you won't get all the power out of it, and you won't get as good gas mileage as you should be getting.

 

what ecu should i go for when i want more power but i can find easy. unlike a gsr or si ecu.

 

i apoligize for my noobishness but i was wondering what are the benifits of putting a b20 on a b18a1 motor? Isnt the b20 tranny a CRV tranny?
