    Hello!
    Iv been having some "issues" with fp green flange threads. Seems like everytime i take turbo apart from manifold it breaks threads from turbo. Its anyoning to pull manifold out to repair thread with helicoil. Never had problems with mhi turbos. Any work around this issue as i dont want to drill it everytime?

    Make sure you use the nickel anti seize on bolts.

    Drill them out and use m8 nuts and bolts with washers. When they seize(they will) you can easily break them in half with a breaker bar, and just replace with new.

    True! Bolts n nuts must be fastest way to do this.

    What bolts are you using when you replace them?

    Best advice right here. I went through this bs many years ago. I tried the good antiseize the mhi bolts heating it up and never failed I always had one or all if they didn't snap the threads would be so galled they'd be unusable. Only had this issue with my 7cm evo 3 housing mind you. I just drilled the holes out and went with I believe 3/8 bolts and washers I ground the bottom side a bit so its flattish 10 yrs later no problems.
