    2.7 stroker TearDown

    hey got a few questions I posted about how my engine wasn't turning over and it ended up being I spun a bearing , got the motor to turn found out 3rd cylinder was done 65 psi , everything else showed 150 along the boards , so no I took the head apart noticed 3rd was lower than 4th when a TDC so im thinking its a spun bearing or bent rod but I doubt the rod bent the car ran for nearly 5 seconds and shut off when this happened I was told by a mechanic it was spun before hand it finally went on me .

    im swapping In a fully re serviced m20b25 as this is my dd clean 230k runs strong and is quiet !

    thing I wanna do with the stroker is rebuild it and get it turbo ready
    what I want to do and need your help on is knowing if I would be able to just replace all the bearings if the cranks okay and the rod hasn't gotten any damage on them as the rings on the pistons were still sealing fine with no problems , if all goes well and I do this get the head decked resurfaced cleaned and put back together few things I had in mind tho are

    -O Ring the block
    -Weld the cylinder head < what r the advantages and disadvantages of this while boosted
    -arp studs
    -all new gaskets
    -Goetz HeadGasket

    and if there anything else I can do im gonna be dd this car ill probably ask the shop to give me 2 tunes for track use and 1 for a dd e30 running a few pound on the road ,

    here's a some pics and 2 videos of my parts car and motor running ,
