Max boost on stock internals?

[MidWest240Collector]

Just what the title says. I plan on running a Garrett GT3071 on an RB20 with supporting mods of course.

<Throws on Flame Proof Suit > I would ask CarlH he has a quick rb20, i think he had 450ish i am guessing, i could be wrong with a gt30, use search... for exact details

how long do you want it to last?the 'how much boost' question is kinda obtuse as there are too many variables that come into play.it all depends on the condition of the motor and how its tuned and driven, hard to say tho.i would be more worried about blowing out hg's than the internals taking a crap at higher boost levels.
