well the 6 b16s ive had RINGLANDS blow up ive had to rebuild beg to differ than 300whp is reliable.
you were lucky, thats all, to my customers, 300whp every day is NOT RELIABLE, the stock motors arent designed to handle that , sorry

i BUILD cars for customers that dont expect to rebuild their motors every month. While it might be ok for YOU to do this, an push the limits so aggresively, its not what we do. We push the limits, but within reason.
