I'm not sure if this is the correct spot for this so I apologize if it's wrong.

I'm going to be turbo charging a 2000 ZX9R engine for a kit car I'm building. I have seen several threads about guys taking them to 12psi with 250-270hp. At that level they have all upgraded pistons and clutch assembly.

I'm looking to go a bit further. The engine will be fuel injected (megasquirt 3 and FIC injectors) and run on E85.

At this point I'm wondering if anyone knows when components start failing and at what HP numbers. rods at 300? crank at 400?

I have no set goal for numbers as of yet. I'm just trying to get a reasonable figure so I can order my fuel system bits.
