Chris if the engine and current ecu came out of euro p11 primera, do you think the ecu would be odb2? Also ill tell you why I am looking, is my buddy bought a b13 with a redtop swapped in car was running fine then one day no start just crank. We changed fuel pump,fpr, distributor, fuel filter, test injectors.. temp sensor, MAF, and CAS still just cranks. So we figure something with ecu any ideas or would odb2 work?
