For a goal of 350 wrhp out of the SR20det what kind of berring should be used on the internals? Stock nissan or should i find some high performance berrings? Who makes high perfromance berrings for the SR20det?

bearings as in.....?

i'd guess all throughout the crank? your stock ones would probably do fine to around 450-500, i hear thats when you need crank reinforcement. i know nismo makes a set, and JUN and TODA probably both have sets, too

SR crackshaft is only good for about 350-400 HP

hmm, thought it was more? other than the crank, what are the internals below the gasket good for, boostwise and HP wise?

The Stock SR internals are good until ~450 HP including the crank and bearings. You can increase the cranks safety limit by having it cryo treated, shotpeaned, magnafluxed, etc. But dont ask me which are better as I am going off info from others on this....... The SR will be fine at 350 hp internally with the proper precautions as far as fuel, etc. An engine management system would make it very much safer but it can be done on a reprogramed ECU.

im talking about the main berrings and stuff. Because i dont want to sink a bunch of money into something then have it spinn a berring 100 miles down the road.
