I want to start a conversion of my AE82 1986 seca with a 4age to a 4agze. I was wondering whether if I get the motor, gearbox and ecu is there anything much else i will need. Will i need a bigger fuel pump..or fuel line. I could get an engine and charger with loom for $680 and source a computer somewhere else. Someone was telling me to check if you get a spark ignitor with it as this is worth about $600 and links into the ecu (not quite sure what it is). The wrecker was telling me i could run the gze off the ge ecu (with switch for charger in car and retard timing but i doubt this claim)
