Look for a thread on skylines austrailia for "why your RB25 blew up" and 90% of the failures are the top ring/top ring land. Good read at how many people are idiots and boost to 20-25 psi without tuning.
first off hes no idiot, and his car was TUNED, he ran it for around a year at the 500whp hp level with zero issues, it was when he began pumping no2 through its cylinders is when issues arrouse, making 595whp, on standard internals through a th350 non the less and an un opened block is a great achievement, so as you can see it did not last. He simply was testing the limits of the block, and well it seems as if he had found them.
awesome video JT, race could be counted in bus lenghts.
