Here's what I got. B20z w/ obd1 gsr head already put togther including complete oil line kit. This is going into a 91 crx si. I have an obd1 gsr wiring harness and ecu with a jumper harness and chipped with chrome. What else will I have to do to get this running? It's already installed in the car as of 25 mins ago by the way with 97 ITR tranny. Any help will be greatly appreciated. This is my brothers account but he said he always got good info here and on b20vtec.com. thanks again
