    Default XU9j engine

    I understand these have been used in early Mi16 cars as well as the 205GTI. Apart from the 16valve head, and perhaps pistons, are they identical? Or at least is the block identical?

    They are identical in terms of dimensions but have different features which makes interchangability difficult. eg engine mount, dipstick hole etc.

    So is the block the same casting or not?

    No, different casting, but things like tunnels, oil galleries, sensor locations etc. are the same. So you can make an 8V out of a 16V block, but not vice versa.

    Hmm. Bummer. I was thinking of getting a Mi16 head and whack that on top of my engine. I understand crank, pistons, conrods etc are the same.

    Pistons aren't the same. Why not just buy an Mi16, they cost virtually nothing nowadays, and pull the engine out of that?
    You would need a shortened inlet manifold and a wedge for the exhaust manifold.

    Have you organised the shipping company yet?
    I can pack things up when I know when they are coming and what they require.

    Thank you Graham.

    Dang pistons.

    I am only trying to assess the possibilities yet.

    I wouldn't like to use the heavier, later Mi16 engine, and earlier versions are high mileage so a rebuild would be in order. If that was the case, then I might as well try to rebuild on the block I hope to get from you.

    That's the idea behind my questions right now.

    If that is not reasonably possible (i.e. requires modifications I would object to like cutting the car's body, or who knows what else), then I will just forget about it and stay with the 8V head.

    What is a wedge manifold?

    Re transport, you have pm.
