Friend of mine would like to have 16v engine in his Astra.
Idea is to take out 20SEH engine with F16 gearbox and put in C20XE with F20 gearbox.
What has to be replaced in wiring system? Is it just wires to the ECU?
What other things have to be done?
it is a straight swap just get the xe loom aswell and double check the wires that are on the plug going to the car loom are the same if your car is a pre 1987 car i think there is a slight difference in the plug wires if it is a post 1988 one you should be ok
