    This whole thread is worthless. If you were serious about this you would do the research yourself. Similar builds have been done on bfc. Search!

    the cylinder wall spacing is exactly the same on all x5x motors. in fact, it's exactly the same as the M20 and M42. I really doubt there is a real difference in cylinder wall thickness, and even if there were, have you EVER heard of somebody blowing out a cylinder bore from boost? I've never heard of such a thing. Usually people end up with broken ring lands from too much advance, or burned valves from not enough, and head gaskets that push out because they used shitty bolts.

    But blowing a hole through the side of the cylinder wall? That's never going to happen. Maybe if you throw a rod through the block, but that's likely from improper assembly or a $shift. If 1 mm less material (on the radius, for 2mm overall) makes the cylinder wall suddenly collapse, I don't think you'd want to use that particular engine for boost in the first place.

    Boring it to 86mm isn't going to hurt it for boost if you use the right hardware. the S52 is already larger than that and they're fantastic for boost. Same damn block too, so you aren't going to suddenly punch through the walls because you did a measily 2mm overbore.
    thanks for the post nando. from what i've read, the problem with boring out an m50/m52 to 85mm+ is that there wont be much headgasket between the cylinders. seems like it would be quite easy to pop at >1.0 bar of boost

    you have no reason to be posting in my thread unless you have knowledge and experience with said situation, and are willing to share in a constructive way, so please stop wasting your time and mine, and gtfo

    Bwahaha you got the same response over there. Awesome. Like Lee said, if your build was actually going to happen you wouldnt be posting dumb questions like these. I have no intention of ever building a M50 stroker yet Ive come upon at least 20 threads detailing the exact parts that go into it over on bfc. I dont know about you but Id rather be an asshole than a moocher anyday.
    go fuck yourself
