Me too! To soon to guess without knowing management and tune/boost etc. I wonder if they'll push it up to around 10 - 12 psi. Definitely subscribed.

Does the 2ZR-FE have decent rods or are they made of cardboard like the 1NZ and blow up before 10psi?

All I know is that the MonkeyWrench Racing guys say that there are a lot of stock 2ZR-FE engines with the turbo kit and minimal failures, assuming a good tune. I was inquiring about my transmission's ability to handle the extra torque. They said that over 275 HP the automatic transmissions started to slip. Despite what they said, I personally wouldn't trust it much beyond 220 - 230 HP. I believe that the engines up to 275 HP were not built engines. I deduced that the engine could therefore hold together up to 275 HP. I would feel reasonably comfortable at 250 crank HP with a good tune, good fuel, decent intake temps and not constantly thrashing on it. By extension, my guess is that the engine should handle 12, maybe 14 psi. Again, very good tune, minimal thrashing. All of this is pure supposition on my part, however. That said, I don't think either MWR or Turbokits would be selling these kits (8.6 psi), intended for a stock engine, if there wasn't some headroom there. It could ruin your rep pretty quickly with a lot of early failures.
