You quoted me, does that mean you’re asking how I would fix it? I would have approached this entire build differently and I probably would have said no in the beginning, these “fix it, it don’t make enough power” deals are a fool’s errand when the budget is as limited as this one seems to be. But if I did take it on I would have done a LOT more measuring and testing before a single nut or bolt was loosened from that engine. It appears to me that Nick is guessing at likely possibilities and he’s going to try each one until one of them gives him the results he wants, then say “I knew I could fix it”. Maybe he does that for content IDK, part 1,2,3,4 etc. Anyway, I won’t even venture a guess as to what’s wrong with it without having more info, as it would just be a guess. But I’d bet a dollar a turbo would work.
