88 Civic HB

Hey hoda lovers I got a question... Just bought an 88 civic DX with a 1.5 DPFI. I have heard of people building up the 1.5 with mini me swaps and what not, but I have also thought about going with the d16a6. If I go with the 1.6 would I have to change my Tranny and ECU?
Any help would be appreciated. Thanks
