I thought one of the weaknesses with the original VQ35 motors was their rod bolts were the first to let go with big power/torque numbers. Does anyone know if the OE bolts were improved over the years with the HR/VHR motors? I guess if you were going to build a motor you would replace the bolts with ARP, but I was curious about the stockers.
as far as switching HR / VHR heads...it sounds good. i'm just not sure if there needs to be any further intense modification needed of them to interchange (unlike the honda motors). i'd just leave the VVEl and spend more on cooling no?
