    Over the last year or so, I've spent a lot of time reading about these engines and their applications in L200/Triton trucks on UK, Aussie, Filipino, Caribbean and New Zealander boards. Not that theoretical knowledge is the same worth that practical experience has. I'd like to think I'm not flying totally blind here (I hope), I'd done homework, but I'm sure everyone would be happy to hear any advice you have to give.

    I'm also not doing a straight swap on a 1st Gen like you did. Is there some issue you've run into with the oil pan that I haven't read about? The only potential issue I've seen is two bolt holes on the oil pan don't quite line up when swapping all the accessories over from a 4D55 on a straight long block swaps. Everything else I've read says it's essentially bolt-in like any Mitsubishi wideblock because the form factor hasn't changed since the 4D55 days.

    There were some issue with fitment when you upgraded the turbo on the brown restoration truck, IIRC, right?

    The exhaust and the turbo are different an that does effect the way the exhaust bolts up. This is not a big deal but needs to be accounted for when making a swap. The valve cover and the head are different.

    The valve cover on a Mitsubishi 4D56 has 2 bolts for the valve cover and the Kia 4D56 has 3 bolts. To make the two interchangeable you will need to machine the head. Machining the head and adding the Mitsubishi Valve cover is about $400. Not a big deal but this is something buyer should be aware of.

    The alternator is different and you will need to address this wiring issue.

    The oil pan is reversed. One is a front sump, while the other is a rear sump. This is kind of a pain and can be a bit pricey to address. Plan on spending a couple hundred bucks to address this issue.

    The water by-pass pipe on the Kia 4D56 end in a 45* instead of a 90* angle like is found on the Mitsubishi 4D56. This is like a $50 Fix.
