i recently bought an em1 with a blown motor. i picked up a complete sir2 swap pretty cheap.. what is all needed to complete this swap and it be headache free..? considering the b16a is an obd1 motor and my car is obd2, what would i need to do to retain obd2 and keep using the p2t ecu..? can't switch to obd1 because of emission testing here in tx.. i know the jdm motors dont have the crank sensor, but aside from that (which can be fixed), what else would i need..? my friend has this exact swap but runs like complete crap..
