This is what you need.
On OBD2a b16a2 with gear box. If you cant find an obd2a you can still do the swap but you''ll need to get either and obd2a D16y7 loom and have it converted to fit the B16a2 engine, or get a 96 to 98 EK vti engine loom but they are hard to find.
B Series drive shafts,
B series engine mounts for an EK.
B Series power steering pump.
B series alt
B series Starter.
B series gear linkage and shifter.
B series Rad as the D series has a smaller inlet and exit pipe. Can be bodged but is not smart.
P28 ecu and obd2a to obd1 conversion harness.
Or a non immobilized obd2a ecu like a jdm teg ecu or obd2a ek9 ecu.
hope this helps you out.
Any questions drop me a pm.
