if you're pushing 160hp then sure it won't be as reliable....but none of that stuff is a super increase in power. The timing chain is a reliability upgrade. People daily stuff that's more souped up than that and it's fine. how well is that motor built, well 
Well, it's a pretty big gamble to to buy this motor and I'm not the betting type. I probably just wasted space on the forum haha. But thanks for the response.
