    Difference between z20let and z20leh?

    Im weighing up a couple of options with the astra just now and one is the obvious 2.0 turbo conversion to either the z20let or z20leh. Im not really looking for differences between the engine internals but more at the engine mounts, gearbox mounts and loom connectors. Would it be a similar task to drop a LEH into a mk4 as it would be to drop a LET in or are there other issues I would need to be aware of? If its the same the leh would be the first choice with it having extra power standard and a 6 speed box
    It would definitely go better with an engine in it

    Fitting is the same but you need to use the ZLET loom/electronics.

    Also you need to fit a ZLET oil sensor (As the loom plug is different) and if its going in a MK4 Astra fit the ZLET inlet manifold so you can use the ZLET servo pipe.
    The truth is always the truth even if you haven't realised it yet...

    So with the electronics would i need the zlet ECU or would the zlet loom work with the LEH ECU?

    so with the ammount of ZLET bits id need to put on the ZLEH its gonna pretty much defy the point of doing it. I might aswel do the ZLET with a VXR turbo and save myself the arse on with trying to get things to work properly. Cheers for the help

    Its basicly the same as fitting the ZLET but fit the LEH 'engine' instead.
