    Astra MK4 engine change.

    guys ,

    i did a search but probably wasnt putting in the correct wording as i found nothing .

    i have a 2001 1.6 sxi astra g Z16XE 104k mileage. i was pondering an engine change to get some more whizz and a lower milage.

    can anyone see any problems or give me a some pointers as to what to go for.

    i was thinking a 2ltr vectra or something similar. what engines will fit/ work with the ecu? will i have to change ecu? can i re use the existing wiring looms?

    cheers

    simon

    your ecu will only work on z16xe's and the ecu has to be kept with your key chip and transponder so if your fitting a different size engine you will have to have the ecu, key chip & transponder.

    if you take the engine from a post 2001 mk4 i don't think you'll have to change the engine bay wiring loom(might have to for some engines?) before 2001 mk4 will have to change the engine bay wiring loom.

    if your putting a faster engine in bigger brakes would be required.

    the fuel line unions might be different, easy swap though.

    different exhaust. different driveshafts. engine mounts. suspension.

    engines from other cars can be made to fit but i don't know enough about that to advise you.

    a good idea is to buy a "donor car" to take all the bits you'll need off.

    the z20let is the most common upgrade in the mk4's as its the fastest mk4 engine.

    it all depends on the engine your wanting to put in
    ps. you'll need an engine hoist or some other way of lifting the engine

    A Z18XE is a very easy swap for an extra 30 bhp.
