Not very long at all.

It is definately a milestone in KA-t progression, and further proves that tuning is a much more important factor in keeping an engine alive then how beefy your internals are.

I see people with forged internals put rods through their blocks alot, and other people with stock internals going forever at 300+ hp.

I dont think this setup would be too reliable, but who needs reliability when you have 500hp I think it does a great job at proving what oem nissan parts can take though, and makes those people running 250-300hp on stock bottom ends feel a bit safer.
