help-ls vtec swap in progress-help

hi im only 17 years old but have been around cars my whole life i have a 1990 integra ls and a 2000 civic si on my integra i was going to put racing cams in the ls motor, i got the cams put them in but broke a rocker arm so the car had to set for a few days untill i could get one ordered while it was setting the cams were STOLEN from my motor along with some other things any way that angered me into ordering a gsr head out of a 2000 integra. i was wondering if i will have to put a b17a obd1 ecu in the car becaause of the obd2 head on the obd1 block is this true? what else will i need to do to finish this swap, i have the help of a machine shop were i work but i just need some info from some hardcore gear heads

Alot of that made no sense at all. But I will try and answer.

You have a 1990 Integra, which is OBD0, you will either need to convert to OBDI, and run a chipped P28 ECU, or a PR3 ECU. Or, if you stay OBD0, you will need a PW0, or PR3 ECU. Just because the head was a OBDII, doesnt mean squat.

Damn those filthy theve's, they should all be shot. Thought that was funny how you said that it angered you into buying a 2000 GSR head. Well it beat's violence anyway right?
