Stock 1mz short block @ 90k. Just had the heads off and cylinder walls, tops of pistons look perfect. The charger went on at ~ 30k so 60k of boost and really no wear. It has stock port matched heads now, just took off "Jims low compression heads" (could never do better then 285 hp with those). Port matched lower intake and supercharger. Throttle body bored a couple of mm. Supra injectors, supra tt maf, cai, fuel pump and of coarse Jp's headers and 3" exhaust. I am controlling the fuel and timing with one of Split Seconds box's (can't remember which one). Also have a SS frequency clamp to unlock the governor (cool to watch speedo point straight down at odometer!).......off the top of my head I thinks the major stuff.
Edit...I normally run 7psi for around 280hp
