Block off plates Turbo oil

So I'm getting conflicting information on bock off plate on turbo motor that it will mess up rods.This is from 5 time national turbo bike rider also said stock crank and regular bolts hold up to 500 hp..............,..Now this is what done to my motor block off plate with mcc flat oil pan with high gear for oil pump.Which i was told raise oil pressure so I bought high performance relief valve 125 and to oil line to turbo .045 restrictor to keep oil pressure to turbo 40-80 psi so high oil pressure suppose to help keep motor crank oil week spot on 1000 the release valve keep from over pressure the block blowing oil filter and such Also have have 5lb release Valve to oil line to turbo so it don't leak when off........Ok what do I do and am I completely wrong and what do I need to do differently?I don't have answer I'm trying find out have lot in motor and turbo and still have lot to do but I need to address this first the person that have me questioning all this does have credentials like I kept being told he 5 time turbo bike national winner but he would say thing with no explanation like ...........block off plate will mess up rods....That a stock crank with standard bolts not studded will handle 500 hp .......that all he saids just comments well it don't sound right to me so I need honest opinion well facts what works and don't work and I know there enough guys on this forum that knows the facts any help will be appreciated. I am learning but I want make sure get right information not just statements that I question.Im not saying I have 500hp motor he just said that comment like it law nobody ask questions seem to care just took his word I won't say his name but from Canada I'm not going bash him......I don't know enough to do so if I wanted to.
