swift conversion

ok i found a 94 swift gt 1.3 dohc engine complite for 350 with intake exhaust alternator startor everything runs its 100miles away from my house waiting on my tax return to come to go get the motor it has 96k miles on it was curious what all i had to change to get it to run i have the fuel pump and filter have a new tranny for it. do i have to change the actual computer system to a obdI? or what sensors do i have to leave out??? and how do i wire in the multi port fuel injection cause the 96 metro with the 1.3 sohc has the singleport carb style injector.
can i just splice the wire and ad the 3 extra injectors or will it not work with the odbII ?
