    Wow, I'd never seen one of those with a turbo diesel in it. That's bad-ass. And I love 620s... and that color too.

    All around, that's quite an awesome truck you have there! More pics/info!

    Yeah I'd post of ratsun. I think someone on there will be able to help. Definitely a sweet truck though.

    The engine name is LD20T. :tu:

    Good engine, very stout, and responds well to more boost. Just tough to find parts for.

    Oh, also the LD28 from the 81-84 Maxima shares some parts with this engine, so hunt those down in the JY if you can.

    California isn't really a hotbed of diesel activity, though. :P
