ok guys I'm kinda stuck here, i have a boosted 97 civic lx thats obd1 and has no cat and no o2 sensors except one is hooked up to an air fuel gauge. i was told i could just put the o2 sensors in and an obd2 ecu and it would be fine but it doesn't have the stock engine. its a zc block with a d16y8 head so will i run into problems if i put the obd2 ecu in it? i thought id be able to just get the exempt sticker but i need to own the car for a year first

any help will be greatly appreciated
