    So recently put a gtx2867r turbo on the 12 MS3. Long story short I had a kinked line that caused low boost, after fixing and using an old tune (per tuner) the turbo overboosted and went boom before I could get off the gas (doing a 3rd great log).

    Have a friend looking at it but I'm guessing I blew up a piston and the bottom out of the block (saw some metal pieces in the oil pool). Hopefully the turbo is ok but wondering if it's worth getting a stage 1 built motor or moving to another platform? Guessing my core is shot and a stage 1 built motor would run roughly 8-10k. New turbo would be another 2k.

    Have a buddy looking to get rid of a G8 GT that is well maintained and pretty well fully bolted (next step is a supercharger). He is giving me a hell of a deal on it (<$20k)but thought I would ask for people's opinions here.

    Thanks

    Depends on what you want to do. You should probably at least get a used motor to drop it in and sell if your looking to change platforms now would be the time

    You think it's worth spending the money on the used motor to sell?

    That's exactly what he said, getting a cx7 motor from a JDM seller, popping it in and selling that will probably be better than trying to sell the roller.

    Although IF your chassis in in good condition then selling it as a roller may be the better option, all depends on what the speeds are going for in your area and how much a used motor will cost you.

    Who would buy a roller? Looking at used JDMs and they are around 2-3k. Chassis is good. Probably worth putting stock parts back on and selling performance parts separately?

    People that want a project, or had a built engine and their chassis is toast.

    Yes if you put a JDM engine in I'd sell it stock and sell performance seperatly especially if you have all your stock parts.

    Where would I post a roller to see if someone wants it? Thanks for all the help I just have never had this happen before and not sure what to do.

    If the chassis is clean and low mileage you will get decent money for it. A roller will probably be around 2000$ regardless of condition
