    Astravan engine conversions - what options?

    With diesel prices soaring through the roof, I'm pondering on swapping out the gutless GM lump in my Astravan for something petrol and going LPG.

    Just wondered what conversions others had done and how hard they were (v6 etc)

    thanks

    mk4 - z20let, 1.8, 2.2 etc anything from a mk4 will go straight in.
    c20xe/let z20leh, c25xe x25xe and other v6s and older engines will go in but mounts and wiring needs altering depending on which one.
    depends what your after, economy or performance.
    if your dead set on economy and dont care what so ever about performance you could go with the 1.6 8v that came in the astra mk4 already running dual fuel.

    Would like something with better performance really, the z20let sounds promising with 200horses.

    you need to use a big block gear box, ideally the f23 that came from the zlet
    easiest way to do it is swap everything from a coupe then you'll get Air con cruise control etc etc.
