    Just what I thought. I just bought a std bore block for 584 shipped and it's nice.

    Priced some 1 mm over Pistons, ..$189 each plus $200-300? machine work, $300 gaskets, bearing, stretch bolts, and I'm at $1200.

    Or buy used std block $600, a used piston $50, gaskets, bearings, stretch bolts $300..total $950-1000

    I could also buy a used eBay engine for about $1500, and then sell my surplus parts and recoupe about $500... Total $1000

    1k for an unknown motor or 1k for a freshly built by you motor?.... no brainer.

    Not much progress to report. The engine is completely disassembled and most of the good parts are on the bench, ignore the GP1300r cylinder in the corner, that is a left over from my rebuild of that machine. The block still has a big hole and smashed piston well, so I'll try to sell it on eBay as a mockup block to someone doing a 4 tec conversion. I was thinking of having my other block which is already .5 mm over, bored to 101mm. I'm not sure if there will be enough material in the sleeves. A stock bore block, used stock piston, new bearings, stretch bolts, and gaskets, is my current plan.
    The intake manifold has a lot of aluminum piston pieces in it, I tried flushing them out but still hear some rattling around. An intake manifold from a 215 with the intercooler is on my shopping list.

    For some reason there was piston debris and motor oil in my intake manifold. I tried washing it out with the hose, blowing it out with my air compressor, even tried my leaf blower, but pieces kept rattling inside. Knowing that even a small pieceo of metal going through an engine can be catastrophic, I decided to remove the spark arrestor. Supposedly removing this restriction increases boost by 1 psi. That may or may not be true, but mine had to go so I could remove piston chunks from it. Click image for larger version.

    Are you a salesman for SBT? I'm sure I can put together a reliable engine for half the cost of an SBT rebuild. $1895 for the engine plus shipping BOTH ways, and my core engine has massive damage and would not be accepted, so that is more money.
