Did the coilpack engine come with the throttle body?
You need to first find out wehter your coilpack engine is an OBD1 coilpack, or an OBD2.
As your dizzy engine is an OBD1.
And obviously there are huge changes to the management on each engines, so you cant use your old ecu.
Once you have found out what your engine is, you then need the correct ecu, loom, sensors etc to match.
And i dont think the obd1 and 2 engines share the same head exactly, due to something i read on vr6oc.
They dont share the same inlet and tb either.
