    Bottom end deaded... what would you do?

    So it finally happened. Haven't really gotten into it yet to see exactly what failed but I'm getting serious blowby so something let go in the bottom end. The m52 lasted about 20,000miles or so of 20psi and ~450wtq so realistically I can chalk that up to a win. Right now my priorities are to the point where I really can't dump a ton of money into it so now I need to figure out what to do.

    I'm running a gt3582r with a spa t3 manifold on pump gas. It was making ~510whp/ 460wtq.

    So I guess it is ...

    1) buy another m52 and get right back where I was
    2) maybe see if the cylinder walls are salvable and keep it a 2.8 and throw some rods/ pistons at it
    3) bore it out a bit and do rods/ pistons

    What would you guys do if you were in this situation? HELP :p

    For 500/450 buy another M52 for $700. It's the most bang for the buck. If you have more money buy an S52 and lower the boost. If you have even more money build a motor, preferably with an S52 crank and S52 bore pistons and aftermarket rods. Or if on a budget, M50 NV rods and aftermarket pistons. Plus cut ring gasket and ARPs.

    Dang I thought you could get an m52 for easily under 500.

    Anything building the engine would be a minimum 2-3k in parts alone I'm sure ehhhh.

    I traded a 3.5" MAF for my m52. They can be had cheap.

    I've gotten whole m52 swaps, with transmissions and harnesses for 400$

    But I'd put an ls in it

    Just get another motor swap it in. Do cutring/spacer. I could pull a motor where I live at the salvage yard for $250usd
