• 1983 Audi quattro-Assembling the Bottom End

    It was about time to start building up this engine. But to build one up, sometimes, you have to tear one down. So, here we go…

    Lonely block in the shop…

    Getting prepped for some paint…

    If it didn’t weigh an extra 51 lbs, and have rust in the passages, I may think this was a shiny aluminum block…

    Stock internals…

    Stock I5 rods and shells…

    AAN pistons…

    Oh, what do we have here???

    Some H-beams…

    Putting in the pistons…

    Bottom end assembled. Everything was plastigaged and radial clearances are .0015-.002 pretty much all around. Pretty typical for anything between new and 200K, lol…
